The external structure of a horizontal jack is very different from a traditional vertical jack. The design of the leveling jack is very special. It doesn’t have the same handle as other jacks, but it does have four casters on the bottom. Relying on this method to improve the portability of the level

Hydraulic jacks and screw jacks use two completely different working principles, one is the Pascal hydraulic transmission principle, and the other is the screw pair transmission principle. Under the action of two working principles, the output can be greatly increased and the force output can be red

Jacks are mainly divided into two types according to different working principles: hydraulic jacks and screw jacks. The usage principles of these two jacks are completely different. One is through the Pascal hydraulic transmission principle, and the other is through the screw secondary transmission

Jack TroubleshootingPressure is one of the two most basic parameters of the jack hydraulic system, which determines the working performance of the hydraulic system to a large extent. The pressure regulation faults are as follows: when the pressure of the jack hydraulic system is adjusted, (1) the sy

Trailer maintenance:1. Daily maintenance:(1) After each operation, the trailer body and chassis should be cleaned in time.(2) Check whether all safety devices and light pens are reliable.(3) Check whether the leaf springs and U-bolts on the front and rear axles of the trailer are loose, displaced, c
