Product Introduction

The crawler scraper has outstanding digging force and powerful loading capacity. It adopts sealed sliding tracks with adjustable tension, which are convenient for maintenance and have a longer service life. Special bucket teeth designed specifically for excavating machinery ensure durability and excellent interchangeability.

The conveying system unloads rocks and coal blocks from the rear into dump trucks, mine cars, belt conveyors, skips and other transfer equipment (the unloading height can be customized according to the user's requirements).



It adopts a hydraulic pilot control system and is equipped with high-efficiency hydraulic valves to increase the movement speed of the boom, bucket arm and conveyor. Even under harsh working conditions, it can achieve excellent comprehensive operation performance. The oil circuit of the medium and high-pressure hydraulic system is symmetrical, and the system protection is complete.

This equipment is equipped with highly interchangeable attachments, allowing for flexible switching among various tools such as milling heads and hydraulic breakers. It can efficiently handle coal seams, soil roadways and rock roadways, significantly expanding its application range. Its lightweight operation, precise lifting and positioning, wide excavation range, rapid material conveying, and environmentally friendly and energy-saving design in line with ergonomic principles especially fill the gap of mechanized mining in small and medium-sized steep slope mine tunnels.


The crawler scraper is a highly efficient continuous excavation and loading equipment, widely used in coal mines, major mining tunnels, railway tunnels, water diversion projects, national defense projects, and the loading operations of rare mineral blocks. It also performs well in open-air bulk material transportation. The track drive system provides powerful propulsion, enabling full-section rock loading without blind spots and eliminating the need for manual cleaning. It can quickly complete disaster reduction and trenching tasks.

This model integrates engineering technologies from Germany and Japan, featuring advanced fault diagnosis, circuit protection systems and double-sealed hydraulic interfaces to ensure system reliability. The ergonomic pilot control system minimizes operator fatigue to the greatest extent, enabling them to operate safely, easily and comfortably in complex terrains. Its structural and performance benchmarks place it at the forefront of the domestic industry.
