Doorways, elevators, narrow aisles, and which lift fits

Most facility managers learn to ask the wrong first question about access equipment. They ask how high it goes. The right first question is whether it gets to the work at all.

Indoor buildings are dimensioned around human passage and goods movement, not equipment access. The standard interior doorway in EU commercial construction is 800 mm rough opening, with effective clear width often closer to 740 mm after door hardware. Standard goods elevators in commercial buildings range from 1.0 to 1.4 metres clear width and 1.2 to 1.8 metres clear depth, with door openings narrower than the cab. Aisles in retail back-of-house and warehouse picking corridors range from 800 mm to 1.4 metres clear.

Indoor pillar lifts are dimensioned for these constraints. Most other powered access equipment is not.

The pass-through dimensions for the Safelift range

Model	Working height	Platform width	Platform depth	Unit weight
PA35	3.5 m	0.55 m	0.65 m	236 kg
MA50	5 m	0.53 m	0.76 m	331 kg
PA50	5 m	0.53 m	0.76 m	331 kg
MA50H	5 m	0.54 m	0.77 m	445 kg
MA50-R	5 m	0.56 m	0.52 m	343 kg
SP50	5 m	0.63 m	0.59 m	386 kg
MA60	6 m	0.53 m	0.76 m	466 kg
PA60	6 m	0.53 m	0.76 m	466 kg

Every model in the range passes through a 740 mm clear-width doorway with hardware mounted, fits inside a 1.0 metre wide goods elevator, and operates in a 1.2 metre wide picking aisle. The MA50-R variant is dimensioned for the narrowest passes, with a 0.52 m platform depth that helps in particularly tight aisles.

What the Safelift dimensions enable that scissor lifts do not

For comparison, an indoor electric scissor lift in the 6 metre class typically has a base width of 800 to 1,200 mm, a stowed length of 1.6 to 2.2 metres, and a unit weight of 1,400 to 1,800 kg. A scissor lift of that size:

• Often fails to pass standard 800 mm doorways, particularly with door frame mouldings reducing clear width
• Rarely fits inside standard goods elevators
• Cannot operate in 1.2 metre picking aisles
• Loads commercial floors at 700 to 900 kg per square metre, exceeding floor ratings in some retail and hospitality buildings

The Safelift range loads floors at around 200 to 300 kg per square metre at the wheels, well inside any commercial floor rating, and passes doorways and elevators by design.

The 740 mm rule

The practical clearance number to remember for indoor work in EU commercial buildings is 740 mm. This is the typical effective clear width of a standard 800 mm rough-opening doorway after door hardware (hinges, latch hardware, doorstop) is accounted for. Older buildings and historic structures often have less.

Every Safelift model has a stowed width below 740 mm, including the wheel housings, with the 530 mm platform variants having particularly comfortable margin.

For routes that include a known sub-740 mm passage, the practical questions are:

• Is the constraint at one specific pinch point or does the whole route narrow?
• Does the constraint occur at the work entry or at a transit junction?
• Is the lift used in this constrained area daily or occasionally?

For occasional access through a tight pinch point, the PA35 (3.5 m, 236 kg, narrow) often solves the problem at a smaller working height. For daily access in tight aisles, the MA50-R (5 m, 343 kg, 0.52 m depth) is purpose-built for it.

Goods elevator considerations

Goods elevators are the second-most-common pinch point and the more frustrating one to discover after purchase. The variables are:

• Door width. Often narrower than the cab itself. Common values are 900 mm to 1,400 mm.
• Door height. Usually 2,000 mm to 2,200 mm. Most pillar lifts in stowed configuration are well below this, but check.
• Cab depth. Common values are 1,200 mm to 1,800 mm. The Safelift platforms in stowed configuration have an overall length of around 1.4 to 1.7 metres including the chassis, so cab depth of 1.5 metres or more is needed for most models.
• Cab load rating. Goods elevators are rated for 600 kg to 2,000 kg or more. The MA60 at 466 kg plus operator and tools sits well inside the 1,000 kg class typically rated for goods elevators.
• Floor finish. Some commercial elevators have polished or smooth metal floors that can mark under the wheel point loading of a 466 kg unit. Castor selection on the Safelift range is non-marking on standard commercial floor materials, but verify on metal-finished elevator floors.

For multi-floor facility work, the goods elevator dimensions and rating should be checked at the site survey stage. The Safelift dealer network does this routinely.

Floor loading

Less commonly raised but important for hospital, museum, and historic-building work: floor loading.

The Safelift range applies wheel point loads of around 80 to 150 kg per wheel under operating conditions. Standard commercial floor ratings of 250 to 400 kg per square metre comfortably accommodate this. Older or specialist floors (suspended timber, museum gallery floors, historic stone) sometimes have lower ratings or specific point-load constraints, and a site survey is needed.

Practical model selection by building type

Building type	Typical constraint	Recommended starting model
Retail store, mid-size	850 mm storeroom doors, 1.4 m goods elevator	MA50 or MA60
Hotel public area	Marble floors, narrow service corridors	MA50 (low floor loading, narrow)
Office building	Standard 800 mm doors, passenger elevator	PA50 or MA50
Warehouse picking aisles	1.2 m aisles, 6 m ceilings	SP50 (with picking table) or MA60
Older or historic buildings	Sub-740 mm doors, lower floor ratings	PA35 (smallest)
Hospital wards	Strict floor protection, narrow service routes	MA50-R (narrow depth)
