1.The components of casing rotator series
1) Working device
Wedge clamping device---Being compared with the traditional clamping mechanism, it can clamp the casing no matter at what position, and keep the vertical accuracy of the casing; and the larger drawing resistance of casing causes greater lamp force.
2) Motor Reducer---4 sets of motor reducer can supply the sufficient torque, transfer a strong rotary force to the casing, which can adapt to the complicated stratum and cut obstructions.
3) Vertical device---Hydraulic vertical device ensures the verticality of drill holes, and corrects the casing angle timely in the construction.
4) Caliber change device---The convenient caliber change makes the equipment adapt to various requirements of caliber change.
5) Auxiliary clamping device---It can better ensure the verticality of casing, and additionally compensate for the problem of low crane capacity of the equipped crane during deep excavation.
