A freight elevator is a vertical transport system engineered to move goods, pallets, equipment and materials between floors of a building. Unlike a passenger lift, it is designed around load-bearing structure, reinforced flooring, wide door openings and controlled loading procedures rather than ride comfort. For warehouses, factories, hospitals, hotels and multi-storey retail across Pakistan, the freight elevator is the piece of infrastructure that determines how fast stock moves and how safely staff work.
Hub Elevator supplies, installs and maintains cargo and freight elevators across Pakistan. This guide covers freight elevator classes, capacity and shaft specifications, drive systems, safety standards, application scenarios and the specification checklist our engineering team uses on site surveys. It is written for building owners, architects, procurement managers and facility teams who need to specify the right unit the first time.
What Is a Freight Elevator?
A freight elevator — also called a cargo lift, goods lift or service elevator — is a powered platform enclosed in a hoistway, rated to carry material loads under a defined loading class. The rating is not simply a weight figure. It defines how the load may be placed into the car: whether by hand, by pallet truck, by forklift that drives in and reverses out, or by a vehicle that parks inside the cab.
That distinction matters structurally. A car rated for forklift loading needs a platform and guide rail assembly that can absorb the concentrated point load of a wheel and the dynamic impact of a truck driving across the sill. A car rated only for hand loading does not. Specifying the wrong class is the single most common and most expensive error we see in the Pakistani market.
Key Components and Structure
Every freight installation is built from the same core assemblies: the car (platform, reinforced flooring, side walls, protective bumper rails), the hoistway (shaft, guide rails, buffers, pit), the drive (traction machine and ropes, or hydraulic pump and jack), the doors (typically vertical bi-parting or vertical lifting for freight duty), and the control system with its safety chain — overload sensing, door interlocks, terminal limits, emergency stop and the governor and safety gear assembly.
Freight cars use heavier gauge steel, checker-plate or hardwood flooring, and door types that maximise clear opening width. Vertical bi-parting doors are common in freight duty because they give the full car width as usable opening and tolerate impact better than horizontal sliding panels.
Freight Elevators vs Passenger Elevators
Buildings frequently try to serve goods movement with a standard passenger car. It works until it does not — finishes get damaged, the door operator wears prematurely, and the unit is out of service during peak trading hours. The two products are engineered to different priorities. If you are also specifying passenger units for the same building, our complete guide to passenger elevators in Pakistan covers that side of the specification in the same depth.
| Parameter | Passenger Elevator | Freight Elevator |
|---|---|---|
| Design priority | Ride comfort, aesthetics, speed | Load capacity, durability, loading access |
| Typical capacity | 4–26 persons (approx. 320–2000 kg) | 500–5000 kg and above |
| Car flooring | Granite, vinyl, decorative finishes | Checker plate steel or reinforced hardwood |
| Car walls | Hairline or mirror stainless, laminates | Heavy gauge steel with bumper rails |
| Door type | Horizontal centre or side opening | Vertical bi-parting or vertical lifting |
| Typical speed | 1.0–2.5 m/s and above | 0.25–1.0 m/s |
| Levelling accuracy | Comfort-driven | Critical — must match forklift sill tolerance |
| Operation mode | Automatic, unattended | Often attendant-operated or key-controlled |
The levelling row deserves emphasis. A passenger car that stops a few millimetres out of level is a minor comfort issue. A freight car that stops out of level creates a lip that a loaded pallet truck must be forced over — which damages the sill, stresses the platform and creates a genuine injury risk for the operator.
Matching Elevator Type to Building Use
Offices and commercial towers. Passenger units handle people; a single service or freight car handles fit-out material, furniture, catering and waste. Without it, goods traffic runs through the passenger lobby.
Factories and warehouses. Freight duty dominates. Specify to the forklift or pallet truck, not to the pallet, and expect Class C1 or C2.
Retail and multi-floor stockrooms. Cage trolley movement during trading hours. Capacity is usually modest but cycle frequency is high and levelling accuracy matters.
Parking structures and showrooms. Class B vehicle loading, where the car is sized to the vehicle envelope and the rated load is the vehicle weight.
Mixed-use buildings. The hardest case. Residential, retail and office tenants have different peak hours and different goods flows. A dedicated freight core, separated from passenger circulation, is almost always the right answer even though it costs floor plate.
Freight Elevator Loading Classes
Loading class is the specification that governs everything else. It is defined by how the load enters the car and how it is distributed across the platform. Getting this right at survey stage determines the platform construction, the guide rail size, the safety gear rating and the machine selection.
| Class | Duty | Loading Method | Typical Application |
|---|---|---|---|
| Class A | Light — general freight | Hand loading, or hand truck within rated load; no single item over 25% of capacity | Offices, hotels, retail stockrooms, hospitals |
| Class B | Medium — motor vehicle | Passenger vehicles driven into the car; load limited to vehicle weight | Car parking structures, showrooms, workshops |
| Class C1 | Heavy — industrial truck loaded | Forklift drives in and remains in car during travel | Warehouses, distribution centres, cold storage |
| Class C2 | Heavy — industrial truck unloaded | Forklift drives in, deposits load, reverses out | Factories, manufacturing plants |
| Class C3 | Heavy — concentrated load | Loading by other means; heavy concentrated point loads | Machinery rooms, plant and equipment transfer |
Classes C1, C2 and C3 all require the platform to be rated for the additional stress of the loading operation itself, not just the static payload. For C1 duty in particular, the combined weight of the forklift plus its load must sit within the rated capacity — a detail regularly missed in tender documents, where only the pallet weight is stated.
Capacity and Car Size Reference
Capacity selection should start from the largest single item you will ever move, not from an average. Measure the footprint of your loaded pallet, cage trolley or machinery skid, add clearance for the operator and for the bumper rails, and work outward from there. The table below gives indicative car platform sizes against common capacity ratings for planning purposes.
| Rated Capacity | Indicative Car Width | Indicative Car Depth | Clear Door Opening | Typical Duty |
|---|---|---|---|---|
| 500 kg | 1100 mm | 1400 mm | 900 mm | Light goods, kitchen service, small stockroom |
| 1000 kg | 1400 mm | 1800 mm | 1200 mm | Hand and trolley loading, retail, hospital |
| 1500 kg | 1600 mm | 2100 mm | 1400 mm | Pallet truck loading, light warehouse |
| 2000 kg | 1800 mm | 2400 mm | 1600 mm | Standard pallet duty, distribution |
| 3000 kg | 2000 mm | 3000 mm | 1800 mm | Forklift entry (C2), manufacturing |
| 5000 kg | 2400 mm | 3600 mm | 2200 mm | Heavy industrial, forklift in car (C1) |
These are planning figures. Final car dimensions are set by the site survey, the available shaft, the loading class and the applicable standard. Two buildings with identical capacity requirements can need materially different cars once door swing, turning circle for the pallet truck and structural constraints are accounted for.
Shaft, Pit and Overhead Requirements
The most common cause of programme delay on a freight project is discovering, after the structure is poured, that the pit depth or overhead headroom will not accept the specified unit. Shaft requirements should be fixed before the structural drawings are issued, not after.
| Capacity | Indicative Shaft Width | Indicative Shaft Depth | Minimum Pit Depth | Minimum Overhead |
|---|---|---|---|---|
| 500 kg | 1800 mm | 1700 mm | 1200 mm | 3600 mm |
| 1000 kg | 2100 mm | 2100 mm | 1400 mm | 3800 mm |
| 1500 kg | 2400 mm | 2400 mm | 1500 mm | 4000 mm |
| 2000 kg | 2600 mm | 2800 mm | 1600 mm | 4200 mm |
| 3000 kg | 2900 mm | 3400 mm | 1800 mm | 4500 mm |
| 5000 kg | 3400 mm | 4000 mm | 2000 mm | 4800 mm |
Pit and overhead dimensions vary with drive type and travel speed. Hydraulic units generally need a shallower overhead but a stronger pit floor to carry the jack reaction. Traction units need greater headroom for the machine and rope terminations, but allow much longer travel. Where headroom is genuinely constrained, a machine room-less configuration or a reduced-stroke buffer arrangement may be viable — both need to be confirmed against the governing standard rather than assumed.
Structural loading is the other half of the conversation. The shaft walls must carry the guide rail bracket reactions, and the pit floor must be designed for the buffer impact load under the emergency condition, not the static car weight. Provide your structural engineer with the manufacturer’s reaction schedule at design stage.
Types of Freight Elevators and Drive Systems
Traction Freight Elevators
A traction unit lifts the car on steel ropes or coated belts driven by a sheave, with a counterweight balancing the car and part of the rated load. Because the counterweight carries most of the static load, the motor only works against the imbalance — which makes traction the efficient choice for tall travel and frequent use. Traction suits buildings above roughly five stops, high daily cycle counts, and any application where travel exceeds the practical reach of a hydraulic jack.
Hydraulic Freight Elevators
A hydraulic unit raises the car on a jack driven by a pump and reservoir. There is no counterweight and no load bearing on the building’s roof structure, so all reaction is taken into the pit. Hydraulics handle very heavy loads at low rise economically and are common in warehouses, workshops and two- to four-stop industrial buildings. Trade-offs are slower speed, higher energy use per trip, greater heat generation, and oil temperature management in Pakistan’s summer ambient conditions.
Machine Room-Less (MRL) Configurations
MRL units place a compact gearless machine inside the hoistway, removing the separate machine room. For freight duty MRL is viable at moderate capacities and is attractive where roof space is unavailable or where a machine room would compromise lettable area. At the heaviest capacities and highest loading classes, a conventional geared traction machine in a dedicated room usually remains the more serviceable choice.
Choosing Between Traction and Hydraulic
The decision is driven by travel height, duty cycle and building structure rather than preference. As a working rule: below four stops with heavy loads and low cycle counts, hydraulic is usually the economical answer; above four stops, or with high daily usage, traction wins on running cost and cycle time. Where the building has no roof structure available to carry machine loads, hydraulic removes that constraint entirely. Where oil temperature and ambient heat are a concern in a continuously operating facility, traction is the safer long-term specification.
Safety Systems and Standards Compliance
Freight elevators carry higher consequence risk than passenger units because loads are heavy, loading is dynamic and operation is often by trained staff under time pressure. The safety chain is not optional equipment — it is the specification.
| Standard | Scope | Relevance to Freight Duty |
|---|---|---|
| EN 81-20 / EN 81-50 | Construction and installation of lifts; design rules and testing | Governing European safety standard for new lift installations |
| EN 81-31 | Lifts for goods only, accessible for inspection | Applies to goods-only lifts not intended to carry persons |
| ASME A17.1 / CSA B44 | Safety code for elevators and escalators | Defines the freight loading classes A, B, C1, C2 and C3 |
| ISO 25745 | Energy performance of lifts | Basis for energy classification and consumption measurement |
| ISO 8100 series | Lifts for the transport of persons and goods | International alignment of design and safety requirements |
Core protective devices you should confirm are included and tested at handover: overspeed governor and progressive safety gear; final and terminal limit switches; door interlocks preventing movement with any door open; overload detection that inhibits start; buffers sized for rated speed and mass; emergency stop within the car; two-way emergency communication; and a manual lowering or rescue provision appropriate to the drive type. For C1 duty, confirm the platform has been designed for the forklift wheel loading, and that the sill and guard are rated for repeated impact.
Insist on a documented commissioning test — load test at rated and overload condition, governor trip test, safety gear set test and buffer test — with signed results. This documentation is what an insurer or a factory inspector will ask for, and it is far easier to obtain at handover than two years later.
Applications by Industry
Warehousing and distribution. Multi-level storage only works if pallets can move vertically at the same rate they move horizontally. Class C1 or C2 units sized to your pallet and truck dimensions are the norm, with levelling accuracy and cycle time as the governing performance criteria.
Manufacturing. Work-in-progress between production floors, raw material to line and finished goods to dispatch. Duty cycles are high and downtime is measured in lost production, so drive selection and spare parts availability matter more than first cost.
Hospitals and healthcare. Bed, equipment, linen, catering and clinical waste movement, kept strictly separate from public passenger circulation. Hygiene-friendly car finishes and reliable levelling for trolley transfer are the priorities.
Hotels and hospitality. Back-of-house service lifts move housekeeping trolleys, F&B, luggage and waste without those flows ever appearing in guest lifts. Service lift capacity is what protects the guest experience during peak occupancy.
Retail and multi-storey stores. Stock replenishment from basement or upper-floor stockrooms to the shop floor during trading hours, sized to cage trolleys rather than pallets in most cases.
Cold storage. Specialised requirements around low-temperature lubricants, condensation management, door sealing and material selection. A standard unit relocated into a chilled environment will not perform reliably.
Why a Dedicated Freight Lift Is Worth the Shaft Space
The argument against a dedicated goods lift is always the same: it consumes floor plate that could be let or sold. The argument for it is operational, and it compounds daily.
Using passenger cars for goods movement damages finishes and door operators, driving unplanned maintenance and premature refurbishment. It occupies passenger capacity during exactly the hours when passenger demand peaks. It creates a manual handling and injury exposure every time staff manoeuvre a loaded trolley through a door designed for people. And it caps throughput — the whole building’s logistics run at the speed of a lift that was never specified for the job.
A correctly sized freight lift removes all four problems at once. It also protects the passenger installation’s service life, which is usually the more expensive asset to refurbish.
Freight Elevator Specification Checklist
Bring these answers to your first supplier conversation and the quotation you receive will be comparable, accurate and far less likely to change:
- Loading class — how does the load physically enter the car? Hand, pallet truck, forklift in, forklift out, or vehicle?
- Rated capacity — heaviest total load including the handling equipment itself, not just the payload
- Largest item dimensions — footprint and height of the biggest thing you will ever move
- Number of stops and travel — total rise floor to floor, and which levels are served
- Door type and clear opening — vertical bi-parting, vertical lifting, or horizontal sliding
- Front, rear or adjacent openings — does the car need to be loaded through more than one face?
- Duty cycle — trips per hour at peak, and hours of operation per day
- Power supply — available three-phase supply, and generator or backup arrangement
- Environment — ambient temperature, dust, humidity, chilled or corrosive conditions
- Structural constraints — existing shaft, pit depth, headroom, and roof load capability
- Standard to be applied — the code the installation must be certified against
- Maintenance and spares — response time commitment and parts availability in-country
What Drives Freight Elevator Cost
We do not publish price lists, because a freight elevator quotation that is not preceded by a site survey is a guess. What we can set out clearly is which variables move the number, so you can interrogate any quotation you receive.
- Loading class — C1 duty requires substantially heavier platform and rail construction than Class A at the same rated capacity
- Rated capacity and car size — the dominant driver of steelwork, machine and rail sizing
- Travel and number of stops — each additional stop adds a landing entrance, door set, fixtures and wiring
- Drive system — traction versus hydraulic changes both capital cost and lifetime running cost in opposite directions
- Door configuration — vertical bi-parting freight doors and multiple openings add cost over a single sliding entrance
- Speed — higher rated speed increases machine, governor and buffer specification
- Civil works — whether a compliant shaft exists, or pit and headroom modification is required
- Environmental specification — cold store, dust-proof or corrosion-resistant builds carry a premium
- Standards and certification — the certification regime and testing documentation required at handover
- Maintenance contract — response time, visit frequency and parts coverage over the asset life
Judge quotations on whole-life cost rather than capital cost alone. Energy consumption, expected component life, parts availability and maintenance response time typically outweigh the initial difference within a few years of operation.
Installation and Maintenance
A freight installation runs through site survey and structural verification, shaft preparation and civil works, guide rail and machine installation, car and door assembly, wiring and controller commissioning, load and safety testing, then certification and handover training. Lead time is driven mainly by manufacturing and shipping of the car and machine, with civil works usually running in parallel.
Maintenance matters more on freight duty than passenger duty because the loads are heavier and the loading action is dynamic. A planned programme should cover rope or chain condition and jack sealing, guide rail alignment and lubrication, door interlock and sill inspection, safety gear and governor testing, brake adjustment, overload device verification, and levelling accuracy checks. Levelling drift is the early warning sign on a freight unit: when operators start reporting a lip at the sill, the installation needs attention before the sill damage becomes structural.
Frequently Asked Questions
What is the difference between a freight elevator and a cargo lift?
In practice the terms are used interchangeably in Pakistan. Both describe a lift designed to carry goods rather than passengers. Formal standards use “goods lift” or “freight elevator”, and the meaningful distinction is not the name but the loading class the unit is rated for — Class A hand loading through to Class C1 forklift-in-car duty.
What capacity freight elevator do I need?
Start from the heaviest single load you will ever move, including the handling equipment. If a forklift drives into the car, its own weight counts toward the rated capacity. Common industrial ratings run from 1000 kg for trolley duty up to 5000 kg and above for heavy manufacturing. Capacity should be confirmed by site survey against your actual pallet and equipment dimensions.
Can a passenger elevator be used to carry goods?
Occasionally and within its rated load, yes — but it is not designed for it. Passenger cars have decorative finishes, horizontal doors and platforms not rated for concentrated point loads. Routine goods use damages finishes and door operators, consumes passenger capacity at peak times and creates manual handling risk. Buildings with regular goods movement should specify a dedicated unit.
What shaft size does a freight elevator need?
Shaft dimensions depend on capacity, drive type and door configuration. As a planning guide, a 1000 kg unit typically needs roughly a 2100 × 2100 mm shaft with 1400 mm pit and 3800 mm overhead; a 3000 kg unit needs roughly 2900 × 3400 mm with 1800 mm pit and 4500 mm overhead. Final dimensions must come from the manufacturer’s drawings before structural design is frozen.
Should I choose a hydraulic or traction freight elevator?
Travel height and duty cycle decide it. Below about four stops with heavy loads and moderate usage, hydraulic is usually more economical and puts no load on the roof structure. Above four stops, or with high daily cycle counts, traction is more efficient to run and faster per trip. Ambient temperature is a further factor — sustained heat is harder on hydraulic oil.
What safety standards apply to freight elevators in Pakistan?
New installations are generally specified against EN 81-20 and EN 81-50, with EN 81-31 applying to goods-only lifts not intended to carry persons. ASME A17.1 defines the freight loading classes A, B, C1, C2 and C3 that are referenced in most tender documents. Insist on documented load, governor, safety gear and buffer testing at handover.
How long does a freight elevator installation take?
Lead time is dominated by manufacture and shipping of the car, machine and doors rather than site work. Shaft civil works normally run in parallel. A realistic programme is set at survey stage once capacity, loading class, travel and door configuration are fixed, and once any pit or headroom modification has been scoped.
What is a Class C1 freight elevator?
Class C1 means the unit is rated for an industrial truck — typically a forklift — to drive into the car and remain inside during travel. It is the most demanding common class, because the platform must carry concentrated wheel loading and absorb the dynamic impact of the truck crossing the sill. The forklift’s own weight forms part of the rated load.
How often should a freight elevator be serviced?
More frequently than an equivalent passenger unit, because loads are heavier and loading is dynamic. Visit frequency should be set against duty cycle and operating environment rather than a fixed calendar. The programme must cover ropes or jack sealing, guide rail alignment, door interlocks and sill condition, safety gear and governor testing, brake adjustment and levelling accuracy.
Why is levelling accuracy so important on a goods lift?
Because a car that stops out of level creates a lip at the sill. Every loaded pallet truck then has to be forced over that lip, which damages the sill and platform, stresses the operator and creates an injury risk. Levelling drift is the earliest reliable warning that a freight installation needs attention.
