Mobile Drill Rig Trucks Stroke 800 mm Industrial Hydraulic Cylinder
Hydraulic cylinders are single or double acting hydraulic motors with linear reversible motion. They are used as driving units of hydraulically operated equipment, vehicle hoists, forest, agricultural and construction machinery, and in the mobile hydraulics generally. Wide variety of types and terminations of cylinders and pistons makes big variability of applications possible.

Feature:
1. Small size, light weight, high strength: Adopting material selection and processing technology of oil cylinder body and piston rod according to the analysis of load frequency strength, fatigue design and welding technology, through ultrasonic flaw detection, Lightweight, high strength, high reliability.
2. Sealing system: The company's unique sealing system design to prevent soil sand dust, reduce oil leakage, get a good piston rod film.
3. Safety / buffer function: according to need, can be easily installed with a variety of special slow return, counter balance and emergency shutdown and other functions of the valve. But also built-in can absorb the shock in the terminal end of the buffer mechanism
4. Series of cylinder is reasonable, and complete series products can meet the needs of heavy haul transportation, mine transportation and city sediment transportation,etc.
5. Operating system is reasonable, overall system performance is more stable.
