The capacity indicator gauge is located in a box
attached to the left side of the platform control console.
This gauge indicates the maximum platform capacity
allowable at any given boom angle and extension based

tioned to HIGH under certain conditions. With the main
boom below horizontal, HIGH ENGINE SPEED will oper-
ate with DRIVE, TOWER TELESCOPE, and TOWER
