The main control station is equipped with a key/starter switch, oil and alternator warning lamps, water temperature gauge, glow plug indicator lamp and an hour meter.
When you turn the key, the 12 volt system is energised and the run stop control solenoid to the run position. The engine can now be started. Movement of the joysticks signals the engine speed control (solenoid pneumatic actuated air cylinder) to maximum speed. When the joysticks are returned to their neutral position the engine speed returns to low idle after approximately three seconds. (A timer unit is fitted in the main junction box and set to three seconds to give this delay).
The remote control is equipped with two joysticks to operate all hydraulic functions. The two-function selector switch allows selection of stabiliser legs or crane arms. The three-function selector switch allows crane combination selections of front 20', 40' and rear 20'(where applicable). This allows joystick signals to be transmitted via relays in the main junction box to the Danfoss control valves and function diverter valves. The joysticks also incorporate micro switches that independently signal the dump solenoid relay and the "PVEM power relay" (powers up the Danfoss control valve coils and sends signal to truck).
An emergency stop button "Mushroom" type is fitted to the remote control to shut down all systems in an emergency.
There are more details on how to use the remote control to operate the cranes in the Section: Crane Operations.
