1、 Introduction to yt4-8a manual hydraulic ejector:
Yt4-8a manual hydraulic ejector is a manual hydraulic sliding device designed to meet the needs of blasting mining and common mining face in coal mine
Compared with other sliding devices, it has strong adaptability, good mobility, labor-saving operation, high efficiency, easy maintenance, safety and reliability
Compared with the sliding of centralized oil supply hydraulic jack, it can save a lot of investment and be cost-effective
It is used together with several types of scraper conveyors such as sgw40t and sgw80t and other small scraper conveyors to adapt to mines with different coal mining forms and meet the requirements of users to a greater extent
It can achieve obvious results in reducing accidents, civilized production and reducing costs

2、 Yt4-8a manual hydraulic ejector structure:
Yt4-8a manual hydraulic ejector is mainly composed of control valve (valve cover, valve body, pull fork, handle, etc
), cylinder block, piston rod, piston ring, check valve, support seat, etc
its liquid supply system shares a set of pump station and liquid injection gun with external injection single hydraulic prop, and the return liquid is discharged to the coal mining face
