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 TR60 rotary drilling rig can reach a maximum rotary speed of 50 r/min. This high speed is designed to solve the soil rejection difficulties commonly faced during small diameter pile hole construction.
Both the main and auxiliary winches are located directly in the mast. This positioning makes it easy for the operator to observe the direction of the rope, significantly enhancing mast stability and overall construction safety.
The rig is equipped with either a Weichai WP4.1 or a Cummins engine. The Cummins engine meets State III emission regulations, delivering economic efficiency, environmental friendliness, and stable performance.
For Kelly drilling, the maximum drilling diameter is 1000 mm with a maximum depth of 21 m. For CFA drilling, the maximum drilling diameter is 600 mm with a maximum depth of 12 m.
No, there is no need to disassemble the drill pipe before transportation. The entire machine can be transported together, making logistics and setup more convenient.
Key imported components include the main pump, power head motor, main and auxiliary valves, walking system, rotary system, pilot handles, and Rexroth motors for the main winch. For the electrical system, the display, controller, and inclination sensor are all imported from world-famous brands.
