Abstract
An aerial work platform supported by a riser boom, a telescoping main boom, and a jib boom. Boom movement may be controlled by a platform control module or a ground control module connected to a controller by a controller area network (CAN). Movement of the platform and the jib boom are limited to a predefined envelope. If an operator attempts to move the platform outside the envelope, the controller automatically retracts the telescoping boom section or automatically levels the jib boom section in order to maintain the platform within the acceptable envelope. Boom section select switches permit the operator to select and move sequentially or simultaneously in different directions. Timers which are part of the system include various interlocks to accomplish safety and power saver features.
