A standard passenger elevator typically has an interior depth of around 1.4 to 1.6 metres. A hospital bed, fully extended with a patient and attending staff on either side, needs a minimum interior depth of 2.7 metres just to fit — and ideally 3.0 metres or more to allow staff to work during transit.
This single dimension makes the case for a specialised hospital elevator more clearly than anything else. A hospital that installs standard passenger lifts during construction and then discovers they cannot move patients on beds or stretchers between wards faces one of two outcomes: a costly retrofit, or a building that does not actually function as a hospital should.
This guide is written for hospital administrators, healthcare facility managers, and contractors involved in medical facility design or renovation in Pakistan. It covers what a hospital elevator must be able to do, how it differs from a standard passenger lift, and what to look for before specification.
Why Standard Passenger Elevators Are Unsuitable for Hospitals
A standard passenger elevator is designed and sized for ambulatory occupants — people who walk in, ride, and walk out — making it fundamentally unsuitable for the primary patient-movement demands of a hospital.
The problems with using standard passenger elevators in medical facilities stack up across four areas:
Size: Standard cabs cannot accommodate a hospital bed with a patient, attendants, and equipment such as IV drips or monitoring devices simultaneously. The minimum cab dimensions required for bed and stretcher movement exceed standard passenger elevator specifications by a significant margin.
Speed and deceleration: Hospital elevators carry patients in critical or post-operative conditions where sudden acceleration or jerky deceleration causes real clinical risk. Standard passenger elevators are not configured for the ultra-smooth deceleration profile that bed and stretcher movement requires.
Infection control: Standard passenger elevator interiors — wall panels, floor coverings, handrails — are not specified for the cleaning regimes or antimicrobial surface requirements of a hospital environment. Horizontal surfaces, gaps, and porous materials that are acceptable in an office lobby become infection vectors in a healthcare setting.
Backup power: A standard elevator without dedicated backup power integration stops during a power failure. In a hospital, a patient in transit between an ICU and an operating theatre cannot wait for power to be restored.
What Makes a Hospital Elevator Different?
Cab Dimensions for Beds and Stretchers
A hospital bed elevator is specified with a significantly larger cab than a standard passenger lift, with interior dimensions designed to accommodate a fully extended hospital bed, a patient, and two to three attending staff members simultaneously.
International healthcare facility guidelines — including those referenced in WHO facility design standards and widely adopted in South Asian hospital construction — recommend a minimum interior depth of 2.7 metres and a minimum interior width of 1.4 metres for a basic bed elevator. For facilities handling bariatric patients or high-dependency units, larger cab dimensions are specified.
Door Width and Door Type
Standard passenger elevator doors typically open to 800–900 mm. A hospital bed elevator requires a minimum door clear opening of 1,100 mm, and more commonly 1,200 mm or wider, to allow a bed or trolley to enter and exit without angling or forcing. Centre-opening doors are standard for hospital elevators, as they provide the widest possible clear opening from both sides simultaneously and eliminate the risk of a door edge contacting a patient or equipment during transit.
Speed and Smooth Deceleration
Hospital elevators operate at moderate speeds — typically 0.63 to 1.0 m/s — which is slower than a commercial high-rise passenger elevator but is not the primary specification concern. More important is the elevator’s deceleration profile: the rate at which it slows to a stop at each landing. Hospital elevators are specified for ultra-smooth, gradual deceleration to prevent movement-induced discomfort or clinical risk for patients in transit.
Hygiene and Surface Specification
Hospital elevator interiors are specified with non-porous, antimicrobial wall and floor surfaces that can be cleaned with hospital-grade disinfectants without degradation. Handrails, if included, are typically stainless steel. Control panels inside the cab are either covered with antimicrobial film or specified with sealed, smooth-face buttons that do not trap contaminants in gaps around the controls.
Flooring is typically a sealed, seamless surface rather than the textured or jointed floor coverings common in commercial passenger elevators.
Backup Power Requirements
A hospital elevator must be integrated with the facility’s backup power system — generator or UPS — to ensure continued operation during power failures, since patient transit between critical care areas cannot be interrupted by load-shedding or outages.
In addition to generator integration, hospital elevators should include an Automatic Rescue Device (ARD) as a secondary backup, ensuring the cab reaches a floor landing and opens even if generator switchover is delayed. For a full explanation of the ARD and its role in compliant elevator installations, see our Elevator Safety Standards guide.

Capacity and Door-Width Requirements in Detail
Capacity specification for a hospital elevator is driven by the combined weight of bed, patient, equipment, and attending staff — not by passenger count in the conventional sense. A standard hospital bed weighs approximately 100–150 kg. A patient and two attendants add another 200–300 kg. Equipment — IV stands, monitors, portable ventilators — adds further load. A minimum rated capacity of 1,600 kg is considered the practical floor for a bed elevator serving general wards; high-dependency and ICU elevators are typically specified at 2,000 kg or above.
Door width is the physical constraint that most often catches hospital planners by surprise. A standard 900 mm door opening cannot accept a hospital bed without angling it, which is both impractical and clinically risky with a patient on board. The 1,100–1,200 mm clear opening requirement should be treated as non-negotiable in the shaft and structural design process, since retrofitting door width after construction is among the most expensive correction scenarios in any hospital building project.
Compliance and Infection-Control Considerations
Hospital elevators in Pakistan should be specified and maintained in line with the facility’s broader infection prevention and control (IPC) framework. This has practical implications for elevator maintenance:
- Cleaning schedules for elevator interiors in clinical areas should be integrated into the hospital’s IPC cleaning programme, not treated as a separate building maintenance task
- Maintenance visits by elevator technicians entering clinical-area lifts should follow the facility’s infection control protocols for contractors — personal protective equipment, access controls, and post-visit documentation
- Any component replacement that involves opening wall panels or flooring should be coordinated with the IPC team to avoid disruption to sterile zones
On the compliance side, hospital elevators should be commissioned with the same load testing and safety device certification as any other elevator installation — and the documentation should form part of the hospital’s building compliance record for any regulatory inspection or accreditation process.

Frequently Asked Questions
Q: What is the standard size of a hospital bed elevator?
A hospital bed elevator should have a minimum interior depth of 2.7 metres and a minimum interior width of 1.4 metres to accommodate a fully extended hospital bed with a patient and two attending staff members. Facilities handling bariatric patients or high-dependency cases typically specify larger cab dimensions. Door clear opening should be a minimum of 1,100 mm, and ideally 1,200 mm, with centre-opening doors as standard.
Q: Do hospital elevators need backup power?
Yes. Hospital elevators serving clinical areas — patient wards, ICUs, operating theatres, emergency departments — must be integrated with the facility’s backup generator system to ensure continued operation during power failures. An Automatic Rescue Device (ARD) should also be included as a secondary backup to bring the cab to a floor landing safely in the event of power interruption before generator switchover completes. In Pakistan’s power environment, backup integration is a clinical necessity, not an optional upgrade.
Q: How are hospital elevators different from passenger elevators?
Hospital elevators differ from standard passenger elevators across five main areas: cab dimensions (significantly larger to accommodate beds and stretchers), door width (wider clear opening, centre-opening configuration), deceleration profile (ultra-smooth for patient safety), interior surface specification (antimicrobial, non-porous, hospital-grade cleanable), and backup power integration (mandatory generator and ARD). A standard passenger elevator cannot be used as a substitute for a hospital bed elevator without compromising both patient safety and facility functionality.
Planning a Hospital Lift Installation or Retrofit?
Hospital elevator specification needs to happen at the structural design stage — not after the building is framed. Getting the shaft dimensions, door openings, and power integration right from the start avoids the most costly corrections in any healthcare construction project.
Hub Elevator‘s team works directly with hospital administrators, facility managers, and project contractors to specify, install, and commission bed and stretcher elevators that meet clinical operational requirements.
