HF525 is a kind of mini-type of drilling rig machine. The max torque of this machine is 50knm, the max drilling depth is 25m and the max drilling diameter is 1400mm. The whole machine’s weight is about 25000kg, whose operation height is 10.9m. This kind of machine has the following advance: great power, compact and flexible, simple operation and less pollution. Using a new type of triangular luffing mechanism not only can satisfy various amplitude requirements during the work, but also optimize the old-style operation mode. Meanwhile, with the steady grand trine structure, the whole machine is more steady and can adapt all kinds of complex topography.
The main features:
• It adopts telescopic mast which has simple structure, high durability, low cost and makes the repair more convenient.
• The power head adopts high position-oriented frame structure guarantees the verticality of kelly bar, which makes construction more convenient, and improves the working efficiency and safety.
• The power head adopts unique patented structure, which features low cost, not easily damaged and convenient for repair.
• Main winch: it adopts originally imported Italy hydraulic motor. It is more flexible and can be lowered freely, and the lifting speed is up to 80m/min, which greatly improves the work efficiency. The main winch is allocated at the front right of the operator, so the operator can observe its work condition and avoid twisted ropes.
