Lift for façade work: how to choose

A building façade is one of the most common uses of a rented lift: insulation, painting, cleaning, installing advertising and flashings, replacing windows, repairing gutters. The machine is chosen differently than for work in a hall: it is decided not only by the height but by what stands under the wall and what the machine will drive over.

Step 1. Calculate the real working height

Start from the height of the highest working point (eaves, cornice, chimney, gable), not from the height of the building. You choose the machine for that figure, remembering that working height is the platform height plus the reach of a person’s arms (taken as 2 m). We describe the details in the article on choosing the working height. For façades it is worth taking a machine with a small margin: a façade is rarely flat, and the platform has to be set at various angles.

Step 2. Check what stands under the wall

This step decides the type of machine:

• Wall accessible head-on, hard ground — a scissor lift is enough. The large platform holds the crew and materials, and the capacity is the greatest in its class.
• Paved strip, shrubs, steps, drive, entrance canopy — you need an articulating boom lift, whose platform goes over the obstacle and beyond it.
• Tall façade, machine must stand far away — telescopic boom lift: a straight boom gives the greatest reach both vertically and horizontally.
• Work inside an atrium or glazed lobby — an electric machine with non-marking tyres, so as not to damage the floor.

Step 3. Assess the ground and access

Around buildings there is rarely level concrete. Fresh fill after an excavation, lawn, paving on a bedding layer or manholes are typical traps. On soft ground you need a 4×4 rough terrain machine, and plates are laid under the wheels and the feet of the outriggers. Also check which way the trailer will drive onto the site and where it will stand during unloading; we have collected a practical checklist in the article how to prepare a site for a lift delivery. For work over basements, an underground garage or a freshly poured slab, allow for the limited load capacity of the floor; there is a separate article on the weight of a lift and floor load capacity.

Step 4. Capacity for materials, not only for people

On a façade it is rarely just one person with a brush. Polystyrene boards, mineral wool, adhesives, flashings, advertising elements: all of this counts towards the platform capacity together with the operator and tools. On boom lifts the capacity is sometimes additionally limited at full reach: the manufacturer then gives two values (unrestricted and restricted range). How to read this is shown in the article on the load and reach chart.

Step 5. Wind, people and formalities

• Wind — the manufacturer gives a permitted wind speed (12.5 m/s for most platforms). On a façade there is also the “sail” effect: large boards in the platform catch gusts and in practice shorten the weather window.
• Zone under the machine — when working over a pavement or the entrance to a building, the area must be fenced off and marked; occupying the road reserve requires the consent of the road authority.
• Qualifications — operating a mobile elevating work platform requires a UDT licence (UDT is the Polish Office of Technical Inspection). If the crew does not have them, we run training courses with an exam, and beforehand you can test your knowledge in the online test.

A lift or scaffolding?

In short: a lift wins for spot, scattered jobs and where scaffolding cannot be erected (drives, planting, a pedestrian route, work over the roof of an annex). Scaffolding wins for insulating a whole wall and continuous work over many days, because it is a permanent working platform and a store for materials. On large projects the two solutions are most often combined.

Frequently asked questions

Which lift should I use for a building façade?

For a wall with no obstacles, a scissor lift is enough: it gives a large platform and capacity for materials. If there is a paved strip, shrubs, steps, a garage ramp or an entrance canopy under the wall, you need an articulating or telescopic boom lift, which reaches over the obstacle. For tall façades (above about 20 m) a boom lift is practically always the answer.

Can a lift replace scaffolding on a façade?

For spot and short jobs (repairs, painting a section, installation, cleaning, replacing flashings) a lift is quicker: there is nothing to erect or take down. For insulating a whole wall, where a crew works for weeks across the whole surface, scaffolding usually wins on cost and on convenience for storing materials. A mixed solution is common: scaffolding on the main wall, a lift for the gables and for places where scaffolding cannot be erected.

How far from the wall should the lift stand?

It depends on the obstacles under the wall and on the type of machine. A scissor lift drives almost up to the wall, but it cannot reach sideways. A boom lift is positioned further away and its arm “goes over” the obstacle, which is why, when choosing one, horizontal reach counts, not just height. The values for a specific machine are read from the reach chart.

Can a lift be used over a pavement or street?

Occupying the road reserve or a pavement requires the consent of the road authority and signage of the work zone; this is the contractor’s obligation, not the rental company’s. When working over a pedestrian route, the area under the platform must be fenced off, because falling tools and material are a hazard.

Which lift should I use for a façade with soft ground around the building?

On a lawn, fresh fill or an unpaved strip along the wall you need a rough terrain machine with 4×4 drive and large wheels, and load-spreading plates are laid under the outriggers and wheels. A typical “floor” machine (an electric scissor lift on non-marking tyres) will sink in and will not get in.
