Product Applications

Excavator is the most widely used construction machinery.
The shock load, harsh working environment, precision movement control require high standards on excavator cylinders.
ROCA guarantees excavator cylinder high performance of abrasion resistance and operation stability in any harsh condition has and gains recognition from every solid customer with good quality at a lower cost.
Roca manufactures full-size excavator cylinders for mini excavators to largeexcavators.

 

Zijin Mining Group Co., Ltd. is a sizable multinational mining group performing most competitively in Chinese mining industry. ROCA locate in the same Zilin Mining output area, as the mining cylinder plant that grew up in the mining industry, we repair and reman a lot of mining haul truck cylinder. For a decade ROCA has been focused on the production of various types of imported mine-used off-highway trucks & mining trucks.Our cylinders are mainly applied to world-famous brands such as Cat, Komatsu, Hitachi, BELAZ, and other famous international brands.
 

 

Single-Acting Telescopic Cylinders
This type of cylinder applies hydraulic pressure in one direction only and the return of the telescopic stages is by load such as a truck-trailer. 
ROCA single-acting multistage hoists are used widely throughout the transport sector, where they are used in tip trucks servicing agriculture, earthmoving, construction, food processing applications. 

 

Double-Acting Telescopic Cylinder
This type of cylinder is constructed with porting to both the annular and full bore area so hydraulic pressure can be applied to both surfaces and the cylinder stages can move in multiple directions without the need of an outside force, such as gravity.ROCA double-acting multi-stage cylinders are used in a wide variety of applications across many industries where space restrictions prohibit the use of a rod cylinder and require a compact telescopic cylinder design.
