YH5160TQZ095T Toggle Type Barrier Truck (Medium)

Crane arm

Lifting type wrecker trucks can generally be equipped with variable-width boom arms in order to lift the damaged vehicle from one end (or one side) or the entire vehicle, straighten it, and facilitate lifting.

It can also use the telescopic and luffing of the boom to pull or hoist the accident vehicle from the subgrade and places near the subgrade to the road surface to straighten it.

Lifting mechanism

The lifting function is the most important function of the wrecker truck. It is to use the telescopic, lifting, and carrying folding actions of the support arm to lift the damaged vehicle from the front or rear, and then drag the whole vehicle away from the scene. The bracket of the wrecker truck has a variety of structural forms. Generally, it can lift the axles, wheels, leaf springs, frames, etc. of the accident vehicle, which is easy to assemble and disassemble.

Hydraulic systems

The flat-plate wrecker truck is fully hydraulically driven and integrates various functions such as lifting, carrying, towing, and pulling.

Hydraulic oil circuit

The hydraulic oil pipe adopts high-pressure galvanized steel pipe, which has high pressure resistance, good heat dissipation performance, beautiful appearance and durability, and its service life can be synchronized with the upper installation;

The hydraulic pipe joint adopts imported card sleeve type rigid connector (Germany), which greatly reduces the phenomenon of oil leakage and oil seepage at the interface, and the service life can also be synchronized with the installation.

Reversing valve

Imported multi-way directional control valve (Italy) is adopted and the installation method is optimized to ensure the safe operation of the multi-way directional control valve under various extreme conditions of use;

Oil cylinder

The inner walls of the cylinder are all boring and rolling processes, the inner walls of the cylinder are harder, wear-resistant and smoother, and the seals are fully protected;

The piston rods (solid) are all heat-treated, with high hardness and thick chrome plating, which can easily cope with high-intensity operations;

Fully use imported sealing components (Germany, the United Kingdom and Italy's special seal series), and adjust each sealing combination according to different cylinder structures in order to achieve the most perfect state of the cylinder;

The piston support ring adopts imported materials with high temperature resistance and wear resistance, and the design requires the use of a double support ring or a large-area single support ring structure.During wrecking operations, such as when the cylinder is subjected to a large lateral force, the high-standard support ring can ensure the stable operation of the cylinder and avoid damage caused by direct friction between the piston and the cylinder wall, the piston rod and the cylinder head;

The high-precision imported CNC machining center is used to process the cylinder piston and cylinder head to obtain a high standard of sealing.
