Product Description

Performance Features

1. The equipment adopts a crawler chassis, and the hydraulic system composed of the engine and hydraulic pump installed at the rear of the upper structure drives the motor reducer of the crawler chassis to achieve self-propelled function.

2. Four hydraulic outriggers are installed on both front and rear sides of the crawler chassis. The main machine can be supported and adjusted for front-rear and left-right leveling without the need to level the construction site ground. The outriggers can be controlled independently and opened and closed freely. During construction, the hydraulic outriggers extend, and the maximum width between the support points of the left and right outriggers can reach 4.5 meters.

3. A gantry sub-frame is installed inside the gantry main frame, which not only increases guiding performance but also makes construction more stable without shaking, greatly extending the service life of the drill pipe. The power head is installed inside the lower end of the gantry sub-frame. Hydraulic cylinders for lifting the power head (including the sub-frame) are installed inside the square tubes of the vertical frame of the sub-frame.

4. The power head adopts the power head of a rotary drilling rig, driven by three 107 variable motors, which increases the output torque. The slurry pump is directly driven by a 90KW motor, avoiding energy loss from electric-hydraulic conversion and reducing construction costs.

5. The hydraulic pump station at the rear of the platform is equipped with two independent hydraulic systems:
