United Academy Scissor Lift 3A Operator Certification Practice Test

In a 3A MEWP the __________ can be positioned at various heights over the base.

Engine Wheels Platform Boom

Correct Answer:

Platform

Explanation:

The platform is the part that can be raised to different heights above the base. In a MEWP, the base stays on the ground (supported by wheels or outriggers), while the lifting mechanism moves the platform up or down to the desired height. The engine provides power to that lifting system, and the boom (if present) helps with reach, but the actual vertical position of the work area is controlled by raising or lowering the platform itself. This is why the platform is the best answer: it is the elevated work area whose height changes relative to the base.
