crawlerdouble rotary headhydraulic

▲ Full hydraulic drives double rotary heads, Constant power variable, Large torque output --Rotary head driven by full hydraulic has the power function of constant power variable. Rev can be adjusted automatically under different load. Large torque, high overload capacity. The measurement is smaller and weight is lighter than electric rotary head, better work stability. --Base on the construction process, inner and outer rotary head can separate upward and downward respectively, relative motion, anti-clockwise rotation to drive inner auger, DTH hammer and outer casing tube. It can be suit for many construction methods. ▲ Large diameter high strength mast, hinged three-points supporting --φ920mm large diameter high strength mast and Hinged 3-point supporting combined with lower cross axle and upper double-bevel sustainer can helps to tilt mast back-and-forward direction, left-and-right direction according to job site condition and construction application requirement , therefore make sure its stability and flexibility when works with heavy-duty attachment. --Max. Lifting force is 80tons which is the highest level in the worldwide market. --Cylinders in the bottom of mast and and double-bevel sustainer can provide easy direction control,verticality for simplified operation and high vertically precision.
