A crawler mucking loader is designed for tough mining conditions, offering high adaptability, strong stability, and long service life. Its durability and performance make it the preferred choice for complex underground operations.
How Are Key Parts Reinforced?
The crawler assembly uses ZG42CrMo forged steel track links with hard alloy bushings. This gives it a lifespan of up to 8,000 hours. The chassis frame has a box-section beam design, which provides 3.2 times higher torsional rigidity than wheel loaders. The drive sprocket is supported by double-row roller bearings, allowing an overload capacity of 220% of its rated value.
How Does It Reduce Wear?
Crawler plates are surfaced with a tungsten carbide wear layer of at least 8 mm, cutting wear by 57% in rocky conditions. The support rollers use triple lip seals filled with lithium grease, reducing dust intrusion by 90%. This ensures smooth operation and less downtime.
Can It Extend Maintenance Cycles?
Yes. The crawler mucking loader reduces lubrication points by 40% compared to wheel loaders (23 vs. 38 on average). The hydraulic oil change cycle is extended to 2,000 hours, compared to just 1,200 hours for wheel types. This lowers maintenance costs and increases machine availability.
How Does It Handle Heavy Loads?
The maximum digging force reaches 180 kN (ZWY-210TD), allowing it to directly handle large 1.2 m³ rocks. With a ground contact area 2.3 times larger than wheel loaders, the crawler distributes ground pressure more evenly, improving stability in soft or uneven terrain.
A crawler mucking loader stands out with reinforced components, reduced wear, extended maintenance cycles, and superior load capacity. These features make it a reliable and cost-effective solution for underground mining operations.
