Crafts Process Hardening Force Remove
In the whole crafts process, there are 2 times remove hardening forces: the first remove hardening force in the heat treatment process, hardening force remove is about 80%; the second remove hardening force in the surface treatment process, hardening force remove is about 90%-95%. Therefore, the piston rod is not easily deformed during use or transportation.

Product advantages:
When the pressure oil from the rod into the cavity, effective area of the piston cylinder extends, line to the end, effective area of the piston of the cylinder to lend, telescopic hydraulic out of order is from large to small in turn out, get a long working stroke, extended cylinder effective area is smaller, faster out, therefore, extended speed is slow and fast, the corresponding hydraulic thrust from large to small, this thrust, speed change law, is suitable for variety of automatic loading and unloading machinery on the thrust and speed requirements, in the back of the order is generally in order to retract, axial length of the retracted shorter, less occupied space, compact structure, commonly used in construction machinery and other walking machinery, such as cranes, dump truck and other hydraulic systems
Applications:
The cylinders produced in DALLAST company are mainly used on:
1.Tipping vehicle;
2.Tipping trailer;
3.Tipping skip;
4.Side tipping vehicle;
5.Compressed equipment, etc.
