Working principle and structure analysis diagram of hydraulic boarding bridge

The boarding bridge is also called warehouse adjustment cargo platform, height adjustment plate, warehouse adjustment panel, and hydraulic boarding car. The purpose is to achieve a smooth connection with various types of freight cars with different heights by adjusting the height of the warehouse cargo platform, which is convenient for loading and unloading.

The hydraulic boarding bridge is a special auxiliary equipment that realizes the fast loading and unloading of goods. Its height adjustment function makes a bridge between the truck and the cargo bed of the warehouse. Through this, forklift trucks and other handling vehicles can directly drive into the truck for bulk loading and unloading. Only a single person is needed to realize the fast loading and unloading of goods. The regulating plate (abbreviation: boarding bridge) enables enterprises to reduce a lot of labor, improve work efficiency, and obtain greater economic benefits.

Working principle of hydraulic boarding bridge:
Press and hold the electric control button, the motor runs, the hydraulic pump works, and the main panel rises. When the panel reaches the maximum height, the hydraulically controlled directional valve opens, the spool oil cylinder works, and the slab opens. Then release the button, the hydraulic pump station stops working, the hydraulic boarding bridge descends under the effect of its own weight, so that the oil return of the panel oil cylinder flows back to the tank through the throttle valve, and the hydraulic boarding bridge slowly falls. After the loading and unloading work is completed, press and hold the electronic control button to lift the main panel, the slab is reset under its own weight, the oil return of the flap cylinder returns to the fuel tank, release the button (can not reach the highest position of the main panel), the main panel descends and boarding Bridge reset.

Structural diagram analysis:
The boarding bridge is composed of a panel, a slab, an underframe, a mechanical jack, a hydraulic transmission system, and electrical control. The main components are as follows:
