Howo NX Heavy Duty Dump Truck Chassis 6x4 380hp 10 Wheels Tipper Truck Chassis

Selection of chassis and top mounting for dump trucks

The dump truck mainly consists of a hydraulic dumping mechanism, carriage, frame, and its accessories.

Among them, hydraulic dumping machine

The structure and carriage structure vary from manufacturer to manufacturer, and the following are two

aspects based on the type of carriage and lifting mechanism:

The structure of the dump truck.

The structure of the engine, chassis, and cab of a dump truck is the same as that of a general truck.

High pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and there

is a safety guard board in the front of the carriage.

The engine drives the hydraulic pump through a transmission and power take-off device, and the hydraulic

tilting mechanism of the carriage is composed of an oil tank, hydraulic pump, distribution valve, lifting hydraulic

cylinder, control valve, and oil pipe.

The engine drives the hydraulic pump through the transmission and power take-off device, and high-pressure

oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, pushing the piston rod to tilt

the carriage. Tilting in the future is more common, and by controlling the piston rod movement through the

control system, the carriage can be stopped at any desired tilting position. The carriage is reset using its own

gravity and hydraulic control.

Car type

The configuration of the carriage structure can be roughly divided into ordinary rectangular carriages and

mining bucket carriages according to their different purposes

(As shown in the right figure).

(1) Ordinary rectangular carriages are used for the transportation of bulk goods. The rear panel is equipped

with an automatic opening and closing mechanism to ensure the goods are delivered

The object was unloaded smoothly. The thickness of the ordinary rectangular carriage plate is: front plate

4-6, side plate 4-8, rear plate 5-8, and bottom plate 6-12.

For example, the standard configuration plate thickness for a regular rectangular carriage of a Shaanxi

Automobile brand dump truck is: 8 on the bottom and 4 on the sides.

(2) The mining bucket carriage is suitable for transporting goods with larger particle sizes such as large

stones. Considering the cargo's

Impact and collision, the design shape of the mining bucket carriage is complex and the materials used are

thick. For example, Shaanxi Automobile brand dump truck

The standard configuration of the mining bucket carriage has a plate thickness of 10 sides and 6 sides at

the bottom, and some models have some corners welded on the bottom plate

Steel to increase the stiffness and impact resistance of the carriage.
