1. Control system: remote control + manual operation, fast and safe, proprietary technology, industry-leading;

2. Hydraulic system: cylinder, pump and valve are specially designed by our company and produced by well-known factories in China, which are matched reasonably and cost-effective; Key parts adopt imported seals, stable performance, reliable quality;

3. Safety protection :(1) the main oil cylinder is equipped with built-in two-way unloading valve, which can effectively reduce the system pressure at the end of stroke and protect the whole hydraulic system and the pull arm for durability; (2) the lifting system is equipped with a balancing device, which can move at a uniform speed without load or heavy load to avoid damage to vehicles or equipment caused by strong impact; (3) two-way overload protection is provided for the hydraulic system and oil lines of each branch. Rated pressure is adjusted according to the actual working conditions of each moving part to effectively avoid the abnormal damage caused by system overload or improper use; (4) explosion-proof locking device is installed in the hydraulic system of oil road to prevent potential safety risks caused by the explosion of oil pipe and ensure the safety of personnel and vehicles; (5) the arm mounting is equipped with the reinforced hydraulic cabinet locking device to ensure the proper use of transport safety.

4. Interlock protection: interlock protection is associated with each action to prevent hydraulic or mechanical failure caused by wrong operation, eliminate safety risks and extend the service life of the vehicle;

5. The pull arm structure is made of high-strength steel with special local treatment, strong bearing capacity and not easy to deform.

6. The upper part of the pull arm is polished and derusted, and painted in multiple processes to ensure that the appearance and color meet the requirements; Pull arm mounting assembly through the special bench test and heavy load load test, to ensure the quality!
