valve. Remote control is proportionally variable. Remote control (10) is provided with an emergency shutdown
capability and designed so that when activated, all remote control crane functions cease. The operator can operate the
remote control anywhere within 30 ft (9.2 m) of the crane base. The controller has multiple functions to match control
levers on the crane controls.
