BETT Drive for coal mine scraper chain tightening conditions of professional research and development of chain tightening control valve after more than a decade of market testing, and continue to improve and perfect, as far as possible to meet the needs of the use of coal mines.

Main features:

● Adopting international advanced anti-corrosion materials to meet the requirements of coal mines using emulsified hydraulic pressure, for many coal mines emulsified hydraulic pressure ratio is not up to standard The same can achieve very good results.

● Compact structure, smaller volume, lighter weight, easy to transport underground;

● Simpler operation, can effectively prevent malfunction;

● Special oil circuit design, smooth direction change, high reliability of braking oil circuit, can effectively avoid motor impact, prolong the service life of the motor; adjustable working pressure, maximum 375Bar, rated flow rate of 120L/Min, to meet the high interchangeability of different models of scraper use occasions.
