Tip 1: tipper trucks need to pay attention to the point when driving
Tipper trucks should not be too fierce when the vehicle starts, and pay attention to the dead centre when travelling. Shift with (speed and speed with) do not hang strongly, the vehicle is moving, the chassis extractor must stop the action. Manual operation valve must be in the middle stop position, it is forbidden to manoeuvre the manual manipulation valve to the lifting and descending position driving, the goods in the carriages are evenly distributed, do not seriously partial load exercise, dumping.

Tip 2: tipper trucks need to pay attention to the point when unloading goods
Before unloading, the tipper truck must confirm that there is no personnel on both sides and rear of the vehicle, and often check whether the lifting limit device is intact, and pay attention to make the vehicle stand firm in the process of unloading. In addition, when lifting the carriages, the engine speed should be controlled within 2000r/min, especially after lifting the carriages to 40°, don’t increase the throttle, so as not to damage the limit valve and other parts.

Tip 3: Tipper trucks need to pay attention to the points after unloading
Some drivers are very sloppy, after unloading the material in the dump truck, without waiting for the cargo compartment and the chassis frame together directly drive the car away, resulting in the rear weight before the light, which is very likely to occur overturning. So in the unloading as well as the whole process of driving away must pay more attention, be careful to make a boat.

If you have mastered all the above three points, then drivers and friends should bear in mind the following points:

1. Do not suddenly push the lifting handle to the “down position” in the middle of full load lifting.
If this operation error occurs, the carriages will rush down, which will bring great impact to the frame, and even accidents will happen. Therefore, should try to avoid the above operation, if there is a need for special circumstances must also be carefully operated, try to slow down the landing speed, must not be fierce will not fall to the bottom of the carriages.

2. Don’t use the brake to unload the goods.
As the inertia force of the hard lifting vehicle is very large (generally 5~20 times of the rated lifting force), it is very easy to cause permanent deformation of the frame, carriages and pay frames to weld, burn the oil pump or destroy the seals, damage to the hydraulic cylinders and other damages, the service life of the vehicle is reduced, and in serious cases, there will also be a rollover accident. Therefore, it is generally prohibited to drive when the tipper is lifting.

3. After unloading the goods, the tipper must take off the extractor before driving.
If this operation error occurs, when the tipper is travelling, due to the extractor is in the position of “engaging”, the lifting oil pump will be in the state of “small cycle” under the high speed and long time no load operation. Resulting in the hydraulic oil temperature rises very quickly, easy to cause damage to the oil pump oil seal, and even the occurrence of oil pump “burned to death” phenomenon; more serious is the operation of the oil pump means that the hydraulic system has a power source, in the process of travelling carriages are prone to automatic lifting of accidents.

4. When driving the extractor can not be located in the “on” position.
If in the “on” state (red light on), the oil pump will continue to rotate, the hydraulic system has a power source, so it will be because of the misuse of the pneumatic control valve on the carriages caused by automatic lifting; At this time, even if the pneumatic control valve in the “down” position, the oil should be entered into the oil pump, which will make the oil pump burned out.
