Boom Lift vs. Scissor Lift: How to Choose

Both machines lift people to work at height, but they move differently.

Scissor lifts: straight up

A scissor lift raises a large platform vertically. It suits work directly above the machine: ceilings, lighting, ductwork and drywall. Electric models are common indoors; rough-terrain models are designed for outdoor ground.

Boom lifts: up and out

A boom lift puts a smaller platform at the end of an arm. Telescopic booms give long straight reach; articulating booms can reach up and over obstacles. They suit exterior work such as building facades, roofs, signage and trees (keeping away from power lines).

How to decide

• Can you park directly under the work? A scissor lift may be enough.
• Is there an obstacle or gap between the ground and the work? Consider a boom.
• Is the floor finished or weight-limited? Ask about non-marking tires and machine weight.

How OSHA classifies them

OSHA treats boom-type aerial lifts under 29 CFR 1926.453, which, among other things, requires that only authorized persons operate them and that a body belt (restraint) or harness and lanyard be attached to the boom or basket. OSHA has stated that scissor lifts are not aerial lifts under that rule but are mobile scaffolds, covered by 29 CFR 1926.451–452 (including guardrails and stability requirements). See the sources below for the official text.
