The working principle of the hydraulic system of the hydraulic lift freight elevator: when the hydraulic lift freight elevator rises, the electric control system controls the motor to rotate, Drives the gear oil pump to rotate. Under the action of the oil pump, the hydraulic oil enters the oil cylinder through the oil filter, the one-way stop valve, and the electromagnetic reversing valve, and drives the piston rod of the oil cylinder to move upward. If you use it frequently and require good load and stability, then buy a folding ladder. If used occasionally. For convenient storage, choose a telescopic ladder.
Nowadays, fishing rod type telescopic ladders are popular on the market, like bamboo joints, they have certain limitations in strength Sex, if a single section is damaged, the entire ladder is useless. On the contrary, slight damage to the folding ladder does not delay the use of the ladder. The emergence of ladders plays a vital role in our lives.
