The maximum speed can reach to 50r/min. It completely solves the problem of soil rejection difficulty for small diameter pile hole construction.
The main and vice winch are all located in the mast which are easy to observe the direction of the rope. It improves the mast stability and construction safety.
Cummins engine is chosen to meet the state III emission requirements with economic efficient, environmentally friendly and stable characteristics.
The hydraulic system adopts the international advanced concept, specially designed for the rotary drilling system. Main pump, power head motor, main valve, auxiliary valve, walking system, rotary system and the pilot handle are all import brand. The auxiliary system adopts the load-sensitive system to realize the on-demand distribution of the flow. Rexroth motor and balance valve are chosen for the main winch.
It is no need to disassemble the drill pipe before transporting. The whole machine can be transported together.
All the key parts of the electric control system (such as display, controller, and the inclination sensor) adopt imported components of international famous brands, and use air connectors to make special products for domestic projects.

The maximum speed can reach up to 50 r/min. This design solves the problem of soil rejection difficulty commonly faced during small diameter pile hole construction.
The TR60 offers options for Weichai WP4.1 or Cummins engines, selected to meet environmental emission requirements while offering stable, cost-efficient, and green performance.
No, there is no need to disassemble the drill pipe before transportation. The whole machine can be transported together, saving set-up and relocation time.
For Kelly Drilling, the maximum diameter is 1000 mm with a maximum depth of 21 m. For CFA Drilling, the maximum diameter is 600 mm with a maximum depth of 12 m.
Critical parts use international brands. The hydraulic system features imported pumps, valves, and motor brands (such as Rexroth motor and balance valve for the main winch), and the electric control system adopts imported controllers, displays, and sensors.
In its transport state, the size is 9020 x 2500 x 3220 mm. While in its working state, the size is 5860 x 2500 x 10700 mm, with a total working weight of 17.5 tons.
