9J5868 D9L Lifting Cylinder CAT bulldozer spare parts

9J5868 D9L Lifting Cylinder CAT bulldozer spare parts

The 9J5868 D9L lifting cylinder is a core lifting and transmission component customized by the original manufacturer for engineering machinery. It is specifically designed for use with the D9L series of medium and large bulldozers. The core function is to drive the lifting and hoisting of the equipment’s working device. It also has the functions of power transmission, load-bearing support, and buffering and stabilizing pressure. It ensures smooth lifting and sufficient power when the equipment is under heavy load. It is suitable for heavy-load operations in various scenarios such as mines and construction sites, and meets the operating requirements of high-pressure hydraulic systems.
This product is an original factory compatible accessory, precisely matched to the D9L series of medium and large-sized construction machinery (mainly medium and large-sized bulldozers). Utilizing precision forging and honing processes, it is compatible with the original factory installation station and hydraulic system, allowing for quick installation without complex adjustments. It can withstand on-site bumps, high and low temperatures, and dusty and oily working conditions. It is tightly sealed and leak-free, operates smoothly and is not prone to jamming, and complies with relevant specifications of GB/T 10827.1-2014 and JB/T 10205-2013.

【Core Technical Parameters】
