German type axles with good performance with very significant advantages: easy to bend the beam axis, the provincial tires, heavy duty bearing load something more reasonable bearing clearance fit with the shaft, lubricate better, less resistance to high-speed performance Well, fuel-efficient S-cam head design and adjustable brake chamber Cylinder bore, making it a greater braking force, and can be more rational allocation of its front in the rear axle braking force, braking force distribution more reasonable. Use special formula shoe, friction coefficient, high temperature, use the brakes better performance, braking distance can be operated with ease, can shorten the braking distance. Shandong Liangshan Zhengyang trailer accessories Co., Ltd. is a set design, manufacture and sales of integrated enterprise main products include axles (American and German), suspension (suits and anti-loaded), 90,50-type saddle cited Block, 90,50 kingpins, sound and energy storage diaphragm spring brake chamber, 15275766708, QQ1781135019, business manager Xue Bin welcome new and old customers letter calls business negotiations.
