ZWY-180/75L crawler scraper slag machine is suitable for large-section inclined shafts and large-slope tunnels. It has 75KW explosion-proof high power and can produce 180 cubic meters of slag per hour. The crawler track has strong traction, does not slip on steep slopes and slippery roads, and the scraper conveys wear-resistant material without clogging.Pilot hydraulic control, full-section slag removal without dead ends, the whole machine is explosion-proof and suitable for gas mines. The core accessories are from first-line brands, and the machine body has high strength and can be connected to mine cars and transfer machines, taking into account slag removal and tunnel maintenance. It is stable and durable in long-term operation and convenient for maintenance.
The Underground Heavy-Duty Rock Star | ZWY-180/75L Large Tracked Mucking Loader
- Product Overview
We are a professional manufacturer of mining loading machinery. We independently develop the ZWY-180/75L tracked mucking loader. It is a high-efficiency explosion-proof slag removal machine. It targets coal mine inclined shafts, large and medium rock roadways, and mixed coal-rock roadways.
To start with, this machine has multiple common aliases. Clients also call it tracked slag loader, scraper mucking loader and dedicated loader for inclined shafts. It fits roadways with cross sections above 3.5m×3.5m. It can handle slopes up to 25 degrees. Its hourly mucking output hits 180 cubic meters. It acts as the core backbone machine for fully mechanized underground tunneling.
Furthermore, it carries a powerful 75kW flameproof mining motor. It matches a full hydraulic pilot control system. Its digging boom owns a wide swing range. It supports multiple daily construction jobs. These tasks include full-face mucking, working face rock cleaning, roadway sorting and trench maintenance. Only one single operator can finish the whole workflow. It greatly cuts underground labor demand. It also lifts overall on-site operation safety.
In addition, its traveling system uses thickened quenched manganese steel tracks. The tracks create a large ground contact area. They deliver strong traction and anti-slip ability. It runs steadily on muddy ground, gravel layers and steep slopes. Inside the machine sits a thickened wear-resistant double-chain scraper trough. It stops material backflow during high-gradient operations. Its rear discharge outlet connects seamlessly with mine cars, belt conveyors or shuttle cars. It realizes continuous material conveying and unloading without interruption.
Moreover, the whole frame adopts integrated casting and welding craft. Wear-prone spare parts get special wear-resistant reinforcement. These parts include bucket teeth, scrapers and track plates. The reinforcement boosts impact resistance and extends service life. The machine follows a modular structural layout. Workers can disassemble, assemble and transport it underground easily. Daily maintenance also takes less time and effort.
Finally, the machine fully meets coal mine explosion-proof safety standards. It runs without open flame. It produces low noise and zero exhaust pollution. It works stably in horizontal tunnels and downhill inclined shafts. We support customized overall dimensions and dumping heights per client demands. Our nationwide after-sales maintenance network offers reliable backing. We supply long-lasting, high-efficiency integrated continuous mucking solutions for all coal mines and tunnel construction projects.
1.1 Structural Drawing Description
Two attached drawings are provided for reference. One displays the complete overall structure of the mine mucking loader. The other marks the maximum working width of the front digging arm.
This equipment matches standard large roadway cross-sections. It covers an ultra-wide excavation zone. It can cover most areas of the working face in one single pass. It cuts down repeated machine back-and-forth movements. It drastically improves underground waste rock removal efficiency. It fits regular excavation and slag removal work for coal and rock roadways.
The diagram shows the maximum working width of the excavating arm at the front of the equipment. This equipment is compatible with conventional roadway cross-sections, offering a wide excavation coverage area. It can cover most of the working face of the roadway in a single operation, reducing repeated equipment movements and significantly improving the efficiency of underground waste rock removal. It is suitable for conventional excavation and slag removal operations in coal and rock roadways.
This schematic diagram shows the overall structure of a coal mine excavator loader (slag loader).
