Product Overview

The HWDL280 Water & Gas Dual-purpose Drilling Rig is supplied by Shandong Hengwang Group Co., Ltd, listed under Drilling and Piling Equipment / Water Well Drilling Rigs. The HWDL series integrates mud rotary drilling and DTH air drilling on a single platform: water drilling for soft strata, air drilling for hard rock. It covers 200–800 m water well depths and doubles as a geological wireline coring rig. A 42–92 kW diesel engine and BW-series mud pump are fitted as standard, and the whole rig is crawler mounted for self-propelled travel between holes.

Key Features

• Two drilling methods on one rig — mud rotary and DTH air
• Adapts to soft soil, gravel and hard rock strata
• 200 m water well drilling, 300 m wireline coring with the same machine
• Crawler mounted, self-propelled on site
• BW-series mud pump supplied as standard

Applications

• Water well drilling for farms, villages and industry
• Geological exploration and wireline coring
• Foundation grouting and anchor holes
• Geothermal and monitoring well drilling
