Indoor Mast Lifts That Fit Through Standard Doorways

Common building constraints

European building standards establish minimum dimensions that affect MEWP access throughout interior spaces. EN 14122-3:2016 requires minimum 800mm clear width for access openings, establishing the baseline for equipment design. Most commercial buildings feature doorways between 800mm and 900mm clear width, measured between door stops with the door open at 90 degrees.

Service elevators present additional constraints, typically accommodating 1000-1500kg loads with 1100mm door widths. The elevator cabin dimensions and weight capacity determine which lifts can move between floors. EN 81-20:2020 requires clear capacity marking visible to users, simplifying equipment selection.

Floor load ratings vary significantly between building types. EN 1991-1-1:2002 specifies office floor loads of 2.5-5.0 kN/m², while raised access flooring systems commonly support 250-500 kg/m² distributed loads. Emergency egress requirements mandate minimum 1200mm corridor widths, though many buildings exceed this for operational efficiency. Modern offices typically feature 2700-3000mm floor-to-ceiling heights, while older buildings may restrict vertical clearance to 2400mm.

Lift dimensions that fit

Successful interior access depends on matching lift specifications to building constraints. Transport width remains the critical dimension - the lift must measure less than the doorway clear width minus adequate clearance for safe maneuvering. A 50mm minimum clearance allows operators to guide equipment through openings without damaging door frames or lift components.

The Safelift PA35 exemplifies doorway-compatible design with 550mm transport width, fitting comfortably through 800mm doorways. The MA50-R narrow self-propelled model achieves similar access at 560mm width despite incorporating drive motors. Both models maintain full functionality while prioritizing compact dimensions.

Weight distribution affects floor compatibility as much as total mass. The PA35's 236kg weight spreads across a 550x650mm footprint, generating acceptable ground pressure for most raised floors. Stowed height determines overhead clearance requirements - all Safelift indoor models remain under 2000mm when lowered, clearing standard doorway headers and corridor obstructions.

Platform dimensions directly impact operator workspace. The PA50 provides 530x760mm platform area while maintaining 530mm transport width, demonstrating efficient space utilization. EN 280:2013+A1:2019 requires 100mm minimum clearance around platform edges during operation, influencing platform design within transport width constraints.

Ones that don't (and why)

Many MEWP types exceed interior doorway dimensions due to fundamental design requirements. Scissor lifts typically measure 760-1200mm transport width because their lifting mechanism requires substantial chassis width for stability. The scissor stack must fit within the base frame when lowered, preventing significant width reduction.

Boom lifts face similar constraints from counterweight requirements. EN 280:2013+A1:2019 stability standards mandate adequate base dimensions relative to boom reach and platform height. Self-leveling outriggers or counterweights add width that cannot be eliminated without compromising safety.

Heavy-duty mast lifts rated above 200kg capacity generally exceed doorway widths due to larger platform requirements and reinforced mast structures. Outdoor-rated units prioritize rough terrain stability over compact dimensions, featuring wider wheelbases and larger tires unsuitable for interior use. Some self-propelled models exceed 600mm width due to drive motor placement alongside the mast rather than within the base frame.

Safelift product matches

Safelift's indoor mast lift range specifically addresses doorway access solutions through vertical mast design and optimized dimensions. The PA35 leads with 550mm transport width and 236kg total weight, ideal for buildings with 800mm doorways and passenger elevators. Its 3.5m working height suits most interior maintenance tasks while maintaining exceptional maneuverability.

The MA50-R represents the most compact self-propelled option at 560x520mm transport dimensions. Despite integrated drive motors, it maintains doorway compatibility while offering 5m working height and 150kg capacity. The rectangular platform design maximizes usable space within the compact footprint.

Standard PA50 and MA50 models feature 530mm width with longer 760mm platforms, balancing interior access with enhanced workspace. Both achieve 5m working height at 331kg weight, suitable for freight elevators and reinforced floors. The MA60 extends reach to 6m while maintaining the same 530mm width profile.

All models utilize push-around or compact self-propelled designs, eliminating width penalties from traditional drive systems. Vertical mast architecture minimizes transport footprint while providing stable, vibration-free work platforms compliant with EN 280:2013+A1:2019 requirements.

Site survey checklist

Accurate site assessment prevents access problems during equipment delivery and operation. Begin by measuring actual clear doorway width - the distance between door stops with the door fully open, not the frame-to-frame dimension. Door thickness, hinges, and handles reduce usable width by 50-100mm compared to nominal door size.

Verify elevator specifications from capacity plates required by EN 81-20:2020. Record maximum weight, internal dimensions, and door widths for both passenger and freight elevators. Measure diagonal clearance if equipment must turn within the elevator cabin.

Document floor load ratings throughout the intended work area. Raised access floors require special attention - obtain manufacturer specifications or conduct load testing if documentation is unavailable. Standard office areas typically support 2.5-5.0 kN/m² per EN 1991-1-1:2002, but verify specific ratings.

Map the complete access route from delivery point to work area. Identify minimum corridor widths, tight corners requiring maneuvering space, and overhead obstructions like sprinkler heads or cable trays. Establish storage locations with electrical access for battery charging - allow 1m² minimum area per unit with adequate ventilation.
