Tipper structural features

Generally in the ordinary dump truck Truck II chassis (when the truck is called after removing Compartment II chassis), based on the design made by the variant, usually from the chassis, power transmission, hydraulic dump body , sub-frame and a dedicated cargo boxes and other major components in the total mass of less than 19t ordinary dump truck, commonly used FR4 ??× 2 type II chassis, namely front-engine rear axle drive arrangement of the total mass of more than 19t of dump truck multi-use 6 × 4 or 6 × 2 drive form.

The power transmission apparatus lifting mechanism generally from the top or side of the transmission assembly mounted PTO output power. PTO driven pump directly or through the oil pump drive shaft, thereby generating hydraulic pressure driving force.

Dump truck tipping device consists of dump bodies from the cargo compartment, sub-frame, the hinge axis and dump lever mechanism and other components.

Hydraulic drive system consists of the power take off, transmission shaft, pumps, piping systems, dispensing valve lift cylinder and other components.

By the safety strut attachment system, lifting limit device, automatic lifting device after box board, container whereabouts guide plate, as well as sub-frame connection device and other components.

Mine heavy dump truck due to the special requirements and use of environmental constraints, and general dump truck has many different characteristics, such as load capacity, low speed, short distance, the axle load limit can not select a larger highway code , and a bad road conditions are good and mobility through, etc. Thus, the need to specially designed chassis, the basic use of the vehicle after unloading short wheelbase FR4X 2 form the cab is generally flat-bias of the seal good single cab arranged in parallel on one side of the engine, with a wide field of vision, well-ventilated, easy to repair power, vehicle space utilization advantages. driveline mechanical drive and electric drive two kinds of forms of coexistence. suspension mostly using leaf springs, there is also silicone rubber suspension or suspension. braking system are dynamic braking which, medium and small-tonnage vehicles using compressed air brake, large-tonnage vehicles will use more oil and gas brake (air over oil) , and has appeared advanced high-pressure hydraulic brakes. cargo box lift mechanism commonly used front-end straight push.
