overview

Introduction

HF700Y crawler multifunctional water well drilling rig is a new type, high efficiency, energy saving and multifunctional hydraulic water well drilling rig, mainly used for drilling water wells, monitoring wells, geothermal air conditioning holes, anchoring, foundation and bridge pile holes drilling, etc. The drilling rig adopts a variety of construction techniques such as DTH hammer impact, mud drilling, reverse circulation drilling, casing follow-up protection wall drilling, etc. which effectively solves the problem of construction drilling in various terrains.

Advantages

1. Equipped with imported optional high-torque hydraulic rotary power head, which is selected according to different construction requirements, greatly saving equipment procurement costs and effectively improving construction efficiency.

2. The loose layer can use roller bit drilling, mud slag discharge, reverse circulation construction, etc. The hydraulic supporting leg of the drill rig has large stroke, which can be transferred and loaded without the need for a crane rig.
