Product Introduction

The power source and main hydraulic components are all advanced foreign products, delivering reliable performance and strong power. Equipped with an AI LCD display system for simple operation, intelligent data storage, and smart switching between multiple work pages. Both rotation and push-pull use electrically controlled two-position low-speed high-torque variable motors, featuring high efficiency, smooth transmission, and strong impact resistance. The push-pull system is configured with a freewheel control system that can be intelligently activated with one key to improve system efficiency. The hydraulic system adopts a combination of dual closed-loop and load-sensing control, providing high transmission efficiency, low heat generation, and significant energy savings. An active cooling system is provided to maintain oil temperature within a reasonable range and further enhance system transmission efficiency.

Key Features:

Both rotation and push-pull motors use Poclain low-speed high-torque motors, offering stable performance, high efficiency, and safe and reliable operation.

Enlarged gripper with increased breakout torque, reducing the risk of stuck drill rods; optimized valve circuit layout for faster gripper control, smoother oil flow, and higher construction efficiency.

Equipped with LCD display and AI system for simple operation, intelligent data storage, and smart switching between multiple work pages.

The gripper can move along the entire stroke, facilitating casing installation during construction and easy breakout of drill tools using the gripper.

The push-pull system is equipped with a freewheel control system that can be switched with one key; intelligent control of high and low speeds improves overall system efficiency.
