Tigerrig DQ225DBS Top Drive
Features
Eliminate mechanical transmission mechanism; main shaft driven directly by motor.
Bearing is grease lubricated, without gear lubrication oil and cooling and filtering system, reducing sealing mechanism and easy for maintenance.
Modularized in design, structure is simple hence less fault points.
Direct motor drive provides higher working torque in a short time reducing drive energy loss.
More effective cooling and radiation of complete machine (arranged with high power blower and multiple air ducts.
