Operation method of rear eight-wheel dump truck

1 indicates that the power take-off is engaged to rotate the gear pump to provide hydraulic oil output; The manual valve controls the gas path to move the pneumatic reversing valve from the middle stop position to the lifting position, and the hydraulic oil is input into the lower cavity of the oil cylinder to realize lifting and start unloading, and the goods are unloaded cleanly after reaching the limit height.

Touch the limit valve to open the gas path, so that the reversing valve returns to the middle stop position; When the manual valve moves to the descending station, the hydraulic oil in the lower cavity of the oil cylinder returns to the oil tank to lower the oil cylinder. There are two forms: rapid descent and slow descent.

2. Generally, the last eight wheels have climbing gears (turtle gears). Dumpers should be unloaded in a flat place, otherwise it is easy to overturn. Relatively speaking, the middle hydraulic jacking is easier to overturn than the front hydraulic jacking. Of course, this is also related to the stacking of goods in the carriage, the height and length of the carriage. Before operation, pay attention to whether there are obstacles such as wires above to ensure that the rear door of the carriage can be fully opened when unloading.

Unloading 3/ 1 should be moved forward appropriately, so as to ensure that the rear door can have room to move and prevent the lifting lug from breaking or the front car from being lifted by the weight of the rear car. If the front wheel leaves the ground for the first time, stop lifting and put on reverse gear to remedy it.

Extended data:

Rear eight-wheel: also known as rear eight-wheel dump truck and two-axle car. Refers to a vehicle that unloads goods by itself through hydraulic or mechanical lifting. Also known as dump trucks. It consists of automobile chassis, hydraulic lifting mechanism, cargo hold and power take-off.
