Power Lock System for Stage Truss Towers

摘要

A power lock system for stage truss towers for remotely locking a climbing truss sleeve block with its tower, thereby distributing the downward load directly into the tower and preventing upward motion. The power lock system for stage truss towers generally includes a remotely controlled locking mechanism that is mounted within a truss tower section with adjustable locations. The sleeve that slides or rolls up the tower is equipped with stirrups to provide a structural receptacle for the locking forks. The sleeve and the locking mechanism are equipped with sensors that indicate the sleeve is in the correct location for locking. The control system displays the status of the sensors and limit switches and uses logic to exercise the rules of operation.
