Hfxt-60/80 Jet Grouting Drilling Rig

Product Description

Application

It is mainly applicable to carbide rotary drilling, screw drilling, pneumatic drill hole hammer, pneumatic drill hole hammer with pipe drilling (optional with rotary jet, pendulum jet, fixed jet) and other drilling techniques. It can also be used in tunnel pipe shed support, rock and soil anchoring, blasting hole, embankment reinforcement, ground source heat pump hole, hydrologic well, foundation pile construction and geological disaster control and other engineering fields.

Note: Users can choose diesel engine power, motor power, or diesel engine/motor dual power.

Introduction

HFXT-60/80 crawler-type hydraulic dynamic impact engineering drill can be used for rotary drilling with common alloy bits and other drilling tools. Conventional ball tooth bits can be used for rotary percussion drilling and high-speed hole formation in rock layers. In unstable strata such as pebble beds, the following pipe drilling tool can be used to drill holes with casing. Supporting hydraulic impact can meet requirements for impact rock drilling operations, liquid discharge, underground micro piles, anchor cables, geological exploration, geothermal hole formation, foundation reinforcement, and slope support.

Key Features

Anchoring suitable for drilling pipe, casing, and combined drilling pipe and casing. Rotary jet grouting for single, double, and triple configurations.
Full hydraulic power transmission, stepless speed change, high drilling efficiency, low labor intensity.
Power head features hydraulic variable speed with high/low gears, reducing fittings, increasing reliability, and simplifying maintenance.
Integrated backstroke device to quickly extract jammed drill pipes.
Manual frequency adjustment on the middle cylinder of the hydraulic impact drill for various geological conditions.
Direct-acting load feedback hydraulic system for energy efficiency.
High-quality hydraulic components for stability and long service life.
Self-walking crawler function for quick and easy maneuverability.
