Construction Vehicle Crane

1 Safety device

Safety device includes torque limiter, swing table lock device, winch over-winding and over-relaxation protect device, outrigger lock device, outrigger bidirectional hydraulic lock, Rear axle steering lock and rear wheel return detector, emergency steering power device, gradienter, hydraulic system overflow valve, balance valve.

2 Torque limiter

Detecting function: Detect the angle of the boom automatically.

Display function: Show operating information such as actual load, handing radius, boom angle.

Caution function: When the actual load exceeds rated lifting load. Torque limiter will give an alarm and stop the operation.

3 Swing table lock device

During the driving process, a plug devise is used to connect the swing table and the carrier to keep the steering parts (swing table, boom) from swing caused by inertia.

4 Winch over-winding protect device

When the load reaches a certain height, torque limiter will stop the lifting and indicating light on the instrumentation board will be on.

5 Winch over-relaxation protect device

When only 3 laps of rope is left on the winch, torque limiter will stop the falling and indicating light on the instrumentation board will be on.

6 Outrigger lock device

During the driving process, a plug device is used. By plugging the outrigger, the device keeps it from extending.

7 Outrigger bidrectional hydraulic lock

Outrigger bidrectional hydraulic lock is used to keep both horizontal and vertical cylinder from retractation.

8 Rear axle steering lock and rear wheel return detector

During the driving process. only front axle steering is needed and the rear should be returned aligned. For this reason a lock device is used and indicating light on the instrumentation board shows the status.

9 Emergency steering power device (emergency pump)

If there is an emergency that the engine can not be started, the crane can be dragged by other vehicles. The emergency pump is driven by battery and supplies power to power cylinder.
