Rotary Drilling Rig TW230

Rotary Drilling Rig TW230 1.Max. Drilling Dia.:2000 mm 2.Max. Drilling Depth: 70 m 3.Max Output Torque: 230 kN.m

Product Specification:

Features of engine :

Volvo boost, mid-cool, electrical control for engine, strong momentum, it can work at the place with 4500mm above sea level with normal condition, Euro 3 emission standards.

Features of rotary drive:

1>Double-motor, double-reducer in the rotary drive,powerful output torque,high ability of stressing. It is with good adaptivity, the speed and output torque can auto-change with different geological conditions;

2>It is installed hydraulic circle systems for separated lubrication, cooling and speed changing system to ensure the reliability and high efficiency of power head.

Features of hydraulic system:

1>Main hydraulic pump system, hydraulic pilot-operated, constant power control.

2>Hydraulic auxiliary pump system: load-sensitivity, hydraulic pilot-operated, proportion control, fast responding, low energy consumption; adopt unique load-flow control valve.

3>Unique lubricated circuit for rotary drive: solve the problem of mixing oil between lubricant oil and hydraulic oil.

4>Balancing valve: the balancing valve for amplitude cylinder and drill mast cylinder with non-pressure design make the speed lifting and falling more stable for drill mast and amplitude mechanism to prevent the big shock.

Features of control system:

1>It can be real time monitored by integrated electronic control system when working, and featured with 16 warning functions.

2>Verticality automatic leveling system of drill mast can monitor the lifting and falling and control the verticality of drill mast.

3>Dynamic and digital display of all execution components on intelligent diagnosis system.

4>Rigorous logical interlocking control to prevent wrong operation by operator.

5>Accurate measurement for drilling depth: the mistake can be controlled less than 10mm, 1mm for drilling depth by unique depth measurement device.
