Auxiliary Cranes 150 Ton Stroke 800 mm Industrial Machinery Hydraulic Cylinder
Feature:
1. light weight, high strenght
Base on the nature of construction work, the hydraulic cylinders
need to suit for high strength, high using frequency, high
fatigability. To promise the stability and reliability of
application.
2. The seal system
select the excellent seal kits from Japan and Germany. Adopt the
advanced physical design, make sure the hydraulic cylinder get the
best piston rod oil film.
3. cylinder body
adopt the good quality alloy honed tube, though cold-drawing and
rolling, to reach an excellent roughness and surface hardness,
improve the wear-resistance.
4. piston rod
middle frequency induction hardening and tempering, chrome plated
on rod surface to improve the anti-rust, wear-resistance and
anti-scratch property.
5. safety/cushioning function
the inside of cylinder set up an cushioning device in the end of
stroke, it can absorb the huge impact.
Specification:
The welding of piston rod adopts fully automatic welding machine
and gas shielded weldin process, while use ultrasonic fault
detector to inspect.
The roughness of scrape barreling in the cylinder barrel is up to
0.4.
The parts shall adopt forging skill and be tempered HB ≥250.
Testing pressure is 35Mpa--40Mpa.

Handover Inspection
3. Final Quality Inspection: External Dimensions Inspection, 100%
Hydraulic Test
4. Type Inspection
Every piece of hydraulic cylinder are tested and will send out only
after they are pasted the each test.
Our company has abundant technical force and perfect testing means.
By making wide technical and business cooperation with many related
enterprises, universities, colleges and institutes both at home and
abroad, and employing senior engineers and software engineers, we
have greatly strengthened and improved our designing, processing,
and testing abilities
