  • Product description

  • Introduction The YGSL-120R drilling rig is a fully hydraulic driven dual power head tracked drilling rig. It can adapt to various drilling techniques and formations, especially in complex working conditions such as loose formations, gravel layers, and fractured bedrock formations, and can provide drilling process solutions. The YGSL-120R drilling rig is widely used in the construction of ground source heat pump holes and hydrological water wells, and is also suitable for the construction of large tonnage prestressed anchor holes and drainage holes in geotechnical engineering such as water electrical station engineering, railways, highway slopes, etc; Construction of pipe shed holes in underground engineering; Grouting reinforcement holes and small foundation pile holes; Preventive measures for disasters such as landslides and rock collapses.

    Main features ● The drilling rig is equipped with front and rear power heads, which can achieve various drilling methods, such as using a single rotation method for the inner and outer drilling tools; Internal drilling tool forward rotation and outer casing reverse rotation drilling method
    ● The power head of the drilling rig is equipped with two speed outputs: high and low. Each gear can be continuously adjusted within its rated speed range, suitable for various drilling processes such as rotary drilling, impact drilling, impact rotary drilling, and spiral drilling
    ● The drilling rig has a high rotational torque and a long provision process, which enables fast drilling speed, strong accident handling ability, and high drilling efficiency
    ● The drilling rig structure is a tracked chassis with integrated loading. The convenience, flexibility, and speed of relocating and adjusting the hole positions greatly shorten the auxiliary time for transferring holes in porous construction on the same site
    ● The hydraulic oil pump, motor, and quick connector of the drilling rig are made of international products, ensuring stable, reliable, and long-lasting performance of the entire machine
    ● The overall structure adopts a modular design. According to user requirements, remote wired walking control device (optional) and safety emergency stop device (optional) can be configured
