3880mm Underground Jumbo Engineering Drilling Rig Electric Motor Diesel Engine
Machine Introduction
The RCZ - 22J Hydraulic Tunnel Jumbo rig is a versatile device that can be used in coal mining, tunnel drilling and transportation infrastructure construction. It is equipped with an environmentally friendly diesel engine and electric motor, enabling fast, zero - emission, low - noise drilling operation. Equipped with an efficient hydraulic impactor and heavy - duty floating stable combination arm, it can automatically perform horizontal positioning and 360 degree rotation, efficiently complete large area drilling operations, and is also suitable for tasks such as bolt fixing. In terms of safety, high pressure closed cycle hydraulic system and double circuit pedal brake system are adopted, equipped with emergency brake device to ensure the safety of operation. The rig is designed with an ultra - narrow articulated heavy chassis and travels at speeds of up to 12 km / h, suitable for underground mine and tunnel digging. Intelligent control system, including automatic casing, impactor closing function, delayed flushing hole bottom and other features, the feed system uses high - strength aluminum alloy beam, stainless steel surface covered and anti - wear liner to ensure a long service life. It is suitable for blasting hole drilling in underground mine, tunnel excavation and bolt fixing.
