Through lifting the platform, the aerial operating machinery send the workers to the designated position in the air for construction. Because of its high working height, high safety, reliability, comfort and maneuverability are required. For this series of hydraulic cylinders, we have realized the  modularization, seriation and lightweight.

The most representative of concrete machinery is pump truck, hydraulic cylinders can be classified as boom, support and pumping according to its function. During the operation, boom and leg cylinder will bear vibration, side load, and need to keep pressure. The master pumping cylinder runs fast, the impact is large, and the front end is immersed in water, which requires high reliability of the hydraulic cylinders.

Crane requires high safety performance, frequent operation during operation, especially shock and vibration, thus require high reliability. At the same time, the limit condition bears large side load, and have higher requirement on hardness and wear resistance of the rod surface. Standardized design,  applications of welding, anti-loosening and other patent technology make our cylinders more reliable.

The working condition of excavator is very bad, with long continuous operation time and large pressure impact, so the requirement on buffer effect is very high. Hengcai hydraulic fully absorbs the advanced technology of foreign excavator cylinder, through independent research & development and the structure optimization , realizes the industrialization of excavating mechanical hydraulic cylinder.  Its reliability reaches the leading level both in china and abroad.
