Core Advantages of Explosion-proof Electric Excavators for Mining Industry

In accordance with national standards for mine safety production and green environmental protection, major mining areas nationwide are comprehensively promoting green and intelligent underground transformation. Explosion-proof electric excavators have become the preferred equipment for underground excavation projects.
Designed for short-distance underground material transportation, the machine is powered by external three-phase AC power supply, equipped with dual servo motors and a complete full-hydraulic control system. It features a compact and lightweight body, low operating noise and zero exhaust emissions without oil fume pollution.
Integrated with integrated digging, grabbing and continuous conveying modules, the equipment offers a comfortable and easy-to-operate cab. It is explosion-proof, eco-friendly, energy-saving and highly efficient, fully meeting the operation standards for high-risk underground mining environments with gas and coal dust.

Six Core Working Functions of Explosion-proof Electric Excavator

This machine integrates six major functions: hydraulic traveling, digging & collecting, roadway floor cleaning, material loading & unloading, rock crushing and multi-angle swinging operation. The working principle of each mechanism is detailed as follows:

1. Hydraulic Travel Mechanism
   Power is transmitted to the driving wheels through hydraulic motors, reducers and transmission shafts in sequence. The hydraulic motor supports three modes: forward, reverse and automatic parking brake, delivering smooth start, stop and braking with outstanding safety and reliability.
2. Digging & Collecting Mechanism
   Hydraulic control levers manipulate the working manipulator to complete a full set of procedures including digging, boom stretching, material grabbing and unloading. The main boom can lift, lower and swing left and right for wide working coverage. A wireless remote control system is available as an optional upgrade.
3. Rock Crushing Mechanism
   Equipped with a hydraulic nitrogen energy-storage breaker, it crushes large surrounding rock and hard rock on-site underground, perfectly matching non-blasting excavation and collapse clearance working conditions.
4. Material Loading & Unloading Mechanism
   Two hydraulic lifting cylinders lift the conveyor frame to the standard unloading height. Hydraulic locks secure the cylinders as stable supporting points to realize continuous loading and discharging operations.
5. Roadway Floor Cleaning Function
   It is specially used to clean gangue, sludge and fine ore at the bottom of roadways, level the tunneling floor, keep underground transport passages unobstructed and create favorable conditions for subsequent tunneling construction.
6. Hydraulic Swing Arm Mechanism
   The working swing arm supports 180° or 360° multi-angle rotation, flexibly adapting to multi-directional excavation and slag removal in narrow roadways.

   This mining excavator adopts foldable 3-section hydraulic arm and end hydraulic breaker, plus front dozer blade for stabilization. Its crawler chassis delivers great trafficability, ideal for scaling, roadway widening and hard rock breaking in metal mines. The compact body suits low clearance underground roadways and can get KA mining safety certification.
