How many gears are there in the dump truck?
If this error occurs, the car suddenly rushed down, it will bring great impact on the frame, and even accidents. Therefore, the above operation should be avoided as far as possible. If there is a special situation, it is necessary to take care of the operation, and try to slow down the landing speedThe dump truck and the road collapsed because of overloadingNever let the cart fall to the ground.
Due to fierce car inertia (usually 5~20 times the rated lift), extremely easy to cause permanent deformation, and pay for the carriage frame frame welding, burning oil seals, damage or destruction of hydraulic cylinder damage, reduce the service life of the vehicle, there will be serious accident. Therefore, the general dump truck is forbidden to lift when driving.
The hydraulic tilting mechanism of the car is composed of an oil tank, a hydraulic pump, an distribution valve, a lifting hydraulic cylinder, a control valve, an oil pipe, etc..The engine drives the hydraulic pump through the transmission and the force taking device, and the high pressure oil enters the lifting hydraulic cylinder through the distributing valve and the oil pipe, and pushes the piston rod to make the car roll over. The tilting of the piston rod is more common, and the carriage can be stopped at any desired tilt position by tilting the piston rod by the operating system. The car uses its own gravity and hydraulic controls to reset it.
Working principle of mud carThe structure of the engine, chassis and cab of the dump truck is the same as that of a general truck.Dump truckThe dump truck is divided into two kinds: rear tipping and side tipping. The piston rod movement is controlled by the control system, and the backward tilting is more common. The piston rod is pushed to make the car tilting and a few two-way tilting.The high pressure oil enters the lifting hydraulic cylinder through the distributing valve and the oil pipe, and the front of the carriage is provided with a safety guard board for the driver's cab.The engine drives the hydraulic pump through the transmission and the force taking device, and the hydraulic tilting mechanism of the car is composed of an oil tank, a hydraulic pump, an distribution valve, a lifting hydraulic cylinder, a control valve, an oil pipe, etc..
Now the mainstream of the latter eight rounds of dump trucks are usually more than 290 horsepower, most of which are at least 9 forward gear, more horsepower 336 horsepower more models, as well as 12 stalls, 12 forward gear, plus two reverse gear! Dump trucks of the 6 and 8 stalls are usually single - axle dump trucks with smaller horsepower.
