MEC has introduced its Proactive Platform Safety System for select slab scissorlifts. The solution is designed to alert MEC scissorlift operators by proactively warning them of overhead hazards with the goal of collision and entrapment avoidance.

A “cone” of safety is projected to detect objects above the machine operator. The sensor will begin detecting obstacles 12 feet 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 system also provides for collision and entrapment avoidance. PPSS provides a proactive warning through an ultrasonic sensor to greatly reduce the risk of an overhead collision or entrapment. The unique 45-degree orientation of the MEC lift control handle is designed so that forward/downward movement will cause the machine to lower if contact is made with an overhead obstacle.
