MEC introduced the Proactive Platform Safety System (PPSS) for select slab scissor lifts, designed to alert MEC scissor lift operators of overhead hazards in order to avoid collision and entrapment.
PPSS works by projecting a “cone” of safety through ultrasonic sensor to detect objects above the machine operator. The sensor begins detecting obstacles 12 ft. above the platform floor. An alarm will sound when an object is identified within the cone, and the frequency of beeps will increase as the object gets closer.
With a predetermined safe distance setting, the frequency of alarm beeps becomes constant, and the machine stops lifting. An override button is available for deliberate closer positioning towards an object.
The unique 45° orientation of the MEC lift control handle is designed so that forward/downward movement will cause the machine to lower if contact was made with an overhead obstacle.
