Product features
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.1.Heavy-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.2.Hydraulic 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.3.The double triangle suspension support drill arm can ensure accurate hydraulic parallel holding function in all directions.4.Heavy-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.
