PLATFORM
The platform has a reinforced steel floor, 1.11
m (43.75 inch) high guardrails with midrail, 6
inch (152 mm) toeboards, and an entrance
gate at the rear of the platform.
PLATFORM CONTROLLER

by an electric motor, powers the cylinder.
Solenoid operated valves control raising and
lowering.
CHASSIS

The platform is raised and lowered using a scissors mechanism. Lift is achieved using a single
stage cylinder.
PURPOSE OF EQUIPMENT
The objective of the work platform is to provide a quickly deployable, self- propelled, variable
height work platform to elevate personnel and materials to overhead work areas.
