Abstract
A power actuator on the base section of a multisection telescoping crane boom can bridge at least one intermediate boom section to operate a biased locking pin retract mechanism employed in a system for remotely controlling the operation of a manual fly section of the telescoping boom. To enable the crane operator to know with certainty that the biased locking pin is in a fully engaged position, a visual indicator on the boom readily viewable from the crane operator's cab is directly mechanically linked to the biased locking pin and moves to the indicating position only when the locking pin is fully engaged.
