The 350-pitch supporting wheels, carrier chain wheels and crawler products are designed and developed independently, which are suitable for 260-300 tons of super-large excavation, breaking the technological monopoly and realizing import substitution.

The wheel body and axle are made of high strength alloy steel with high hardenability, and through the proprietary heat treatment process, they can maximally meet the demand of high strength and high wear-resistance; the seals, bushings and other key components are made of famous brands in the industry, which can meet the requirements of complex loads and all-weather working conditions in the mine.

Crawler plate joints are made of high-quality low carbon alloy high-strength cast steel, molded by whole casting process, pins are made of high-strength medium carbon alloy steel, and key parts are strengthened by tempering and induction heat treatment, which ensures maximum strength and abrasion resistance, and meets the requirements of complex loads in mining conditions. In addition, the assembly connection adopts clearance fit, which is convenient for customers to assemble and replace on site.
