DRIVING MECHANISM

Rotary Head

Mode of double drives with double motors and double reductors is adopted. Torque and rotary speed is matched with load demands so that it can work at work at high-torque and low-speed. Unique lubrication and cooling device ensures that the machine works reliably and stably. The function of throwing-off soil at high speed optimal.

Luffing Framework

Adjustable parallelogram mechanism and equal-load triangle structure is adopted to ensure the stable movement of mast, the positioning accuracy of drilling tool and verticality of mast.

Main/ Auxiliary Winch

It is compact that the reductors are built in the main and auxiliary windlasses. Moreover the windlass has long drum, large diameter and oriented groove. Rope-pressing roller is used to prevent the steel rope from overlapping chaos, slipping, and wearing. Thus it extends its lifetime.

Mast

Mast is designed as a box-type structure with internal strengthen steel plate. This structure is of strong rigidity, good stability, and ensures good anti-contortion and anti-bending performance. Mast is articulated in four sections and foldable in three parts, and it minimizes the outline size of the machine for transport.
