The WK series mining machinery excavator is a collection of our company's years of successful experience in designing and manufacturing mining excavators. It adopts advanced technologies at home and abroad and is suitable for stripping and mining operations in large open-pit coal mines, iron mines, and non-ferrous metal mines. The standard bucket capacity is 4m ³ to 75m ³, and more than 1400 units have been produced. They are widely used in large-scale open-pit coal mines, iron mines, and non-ferrous metal mines for stripping and mining operations. Dozens of products have been exported to more than 10 countries.
Product advantages
Communication frequency conversion system, energy-saving and consumption reducing
High efficiency, energy-saving, power factor close to 1, minimal harmonic pollution to the power grid, low failure rate of AC motors, high equipment deployment rate, advanced technology, representing the current development trend of speed regulation systems.
High level drive, extending service life
Improved the meshing transmission efficiency between the driving wheels and track chains, reduced the wear of the driving wheels and track shoes, significantly increased the strength and service life of the driving wheels and track shoes, and reduced the maintenance workload of the track drive device.
Adopting gear rack pushing method
Compared to the flexible pushing of steel wire ropes, the gear rack pushing structure adopts heavy-duty high manganese steel cast gears with good weldability and alloy steel forged small gears, which have strong cutting ability, high efficiency, and low maintenance costs.
Refined design, long service life
Optimizing material selection and heat treatment processes, optimizing macroscopic and microscopic parameters of gears, improving stress concentration in gears and shafts, and increasing fatigue life; The driver's cab is finely designed to improve safety and comfort.
