How to use wrecker truck crane to lift accident vehicle

The opportunity of heavy duty wrecker truck using the crane to lift the vehicle is not many large wrecker, generally used for uneven pavement or on the ground more obstacles. 
Its work program includes the following aspects: 

1, select the parking space. When the wrecker truck arrived at the scene when the first on-site investigation, the selected point and the main vehicle parked car accidents 
hanging vented, they should try to choose a relatively flat parking places lifting. At the same time to estimate the actual lifting by crane when the weight of the crane observe 
the vehicle is within the working range of the boom, try to make the car close to the main crane vehicles. Consider when choosing a distance by crane in parking spots, including 
the boom in weight lifting to meet the premise of maximum expansion stroke, the tilt angle and horizontal spatial rotation radius covered, remove or avoid obstacles space 
required to rotate the boom thereof, it is possible to reach for the sky to clear cables and other obstructions can not be taken away from a power outage or other special 
measures. 

2, the wrecker truck into parking spots, put it in neutral, pull the hand brake, linked to second gear, so that PTO engaged. Operation, the front and rear left and right legs 
extend control (rear legs around each of the two stop pins must retract it pinned prevent external danger), so that the wheels off the ground about 20 ~ 50mm. If the leg soft 
ground, need to add the sleepers were stuffed cushion. 

3, clean up the towed vehicle. Car accident does not allow officers to stop, the car may affect cargo and lifting objects should be removed to reduce weight, the weight of the 
lift when controlled within a prescribed range, while reducing the impact on the body and objects possibility of hazardous occurrence. 

4. Select crane hook the hook in the car accident where the requirements of the hook or lanyard must have sufficient strength to withstand the weight of the vehicle itself. 

5, hanging out of the rotation stopper pin holder, rotating wrecker truck crane jib to be the direction of elongation of the boom so that the boom is located above the top of 
the vertical center of gravity by crane (estimated), and ready to lay down cables, steel hanging by crane. Before hanging to be carried out and take a good joint, allowed cable 
kinked. Operating shrink cable height, balance hanging objects, uniform rise in order to prevent rollover in an accident when the car lifted to a certain height, the boom will 
rotate to the open space down. Throughout the process of lifting, telescopic boom is not allowed. During rotation, pay close attention to whether the host vehicle stays legs 
sinking condition, found significant subsidence should immediately stop working. 

6, after the elongated boom can lift heavy objects from high point where the load must not be too unilateral and makes the vehicle center of gravity wide range of security, with 
special attention to the crane and wrecker rotation in the longitudinal center status at right angles when lateral line, very easy to load torque due to too much leaving wrecker 
overturning. Generally controls the boom lifting capacity graph to identify or determine the force at the time the boom allows the state. 

7. Upon completion of lifting work, the arm should be fully retracted and locked rotation decreases homing rotating seat, winch cable should be neatly arranged to recover. When 
shrink cable, pay attention to timely hook pulley control lever is coming to an end, not to damage the cable or cause the device to pull off the cable collapse wounding. Then, 
each of the legs to recover the full reset.
