What are the outriggers of the truck crane? What’s the difference?

There are three types of truck crane outriggers: fixed outriggers, single-chamber hydraulic outriggers, and double-chamber hydraulic outriggers.

The fixed outriggers can only be extended vertically, but not horizontally;

The single-chamber hydraulic outrigger is a fixed outrigger box shared by two movable outriggers, and the telescopic stroke of this outrigger is limited;

The double-chamber hydraulic outrigger has a fixed outrigger box for each of the two movable outriggers, and the telescopic stroke of this outrigger is larger than that of the single-chamber outrigger.

Advantages of Crane truck cold riveting craft carriage:

1. The side plate is formed by one-time roll forming of high-strength steel, and the deformation resistance is increased by 60%

2. Longitudinal beams and beams are formed by bending high-strength steel, with higher torsion resistance and stronger bearing capacity.

3. The longitudinal beam and the cross beam are connected by cold riveting, which can effectively avoid the risk of cracking and welding.

4. The cold riveted link is more beautiful, firmer and more durable.

5. The cold riveting compartment is easy to maintain, and the riveting is not easy to deform and the welding is easy to deform.

6. Under load conditions, the tensile strength of riveting is much higher than that of welding.
