Mining hydraulic lifters
Keywords: Hydraulic lifters mining mining hydraulic cylinder device
Specifications:
1.compact structure
2.powerful initial Supporting force
3. Easy operation and convenient
4. fast speed
Mining hydraulic lifter is used for holding tight at coal mining face for HZWA slightly-increased resistance metal pillars in underground coal mining .It is manufactured with hydraulic technology and equipment. It has many outstanding advantages compared with mechanical lifters, such as compact structure, fast speed etc. It is obvious for reducing roof caving accident and ensuring safely producing ,and it is popular with miners.

Use
Mine hydraulic prop lifter is the underground coal mine application of hydraulic technology and equipment manufacturing column lifting tool for coal mining face, the use of the HZWA type incremental resistance metal support is braced for. And mechanical lifters ratio, not only has the advantages of compact structure, convenient operation, high speed, the most outstanding advantage is the initial support force. Reduce roof fall accident to ensure safety in production, the effect is very obvious, is deep the miner's welcome
