product Introduction

Hanfa Group underground tunneling series of drilling RIGS are widely used for underground mining, small tunnel tunneling and bolt hole reinforcement projects. Their well-designed shape, configuration, system control and other aspects will provide customers with a better perforation experience.

HFJ11 specialized designed an ultra-narrow hinged and connected suspended chassis with high passability according to narrow and thin vein mining mode and roadway size characteristics, which is very suitable for underground ultra-small roadway turning operation.Modular fast disassembly connection combined design can be very convenient to realize the whole machine piecewise disassembly and downhole assembly work.

Features

  • 1Heavy-duty aluminum alloy propulsive beam with high flexural and torsional strength and long service life;The surface of the propelling beam is covered with stainless steel, and teflon wear-resistant gasket is used between the moving parts to improve the service life.
  • 2Hydraulic rock drilling control system, with automatic opening, no lubrication, no water, no impact, rotary pressure automatic control push back, push pressure automatic control impact and self-moving anti-caxuan functions.Walking before and after two speed shift, overload climbing, the engine does not shut off, automatic appropriate zone speed reduction and increase output torque.
  • 3The double triangle suspension support drill arm can ensure accurate hydraulic parallel holding function in all directions.
  • 4Heavy-duty articulated chassis, four-wheel drive;It is driven by four-cylinder diesel engine.Four hydraulic support legs for stable positioning;Double-circuit pedal brake with emergency stop brake can also brake safely under the premise of damage of one or even two pipelines.
