Product Description

I. Brief Introduction

SL500S water well drilling rig is a top-drive, high-efficiency, multi-functional full hydraulic drilling rig, easy to use, high operating efficiency, reliable and durable, widely used in drilling water wells, detection wells, dewatering wells, rescue wells, ground source air conditioning holes, coal bed methane, natural gas, oil mining and other projects.

It can be drilled either with compressed by DTH hammer drilling or with mud pump by cone bit/drag bit drilling in various formations in high temperature areas, high cold areas, and plateau areas, in the range of rock hardness f=4-20 with efficiency high drilling speed. 

The drill mast motions like lifting and adjusting, rods loading/unloading, rotary and forwarding, and the jacks and winches all controlled by the hydraulic system, easy to manipulate and reduced the labour intensity and preparing time, improved the working efficiency and quality. 

Type of Chassis: Truck Mounted or Crawler Mounted optional.
