TYHI’s WK series excavators are heavy-duty equipment used for open-pit mining. Their development came about through a combination of years of experience manufacturing mining shovels, implementation of advanced technology and design from home and abroad. They are suitable for both stripping and excavating open-pit coal mines, iron mines and ferro-metal mines.

WK series excavators boast a number of state-of-the-art features such as three-dimension imitation and definite circle analysis. They are notable for their performance and ability to be used with a variety of haul trucks and crush stations to better satisfy users’ requirements for higher loading and lower production costs.

Our excavators’ electric system uses a rectifier/regeneration communal DC bus-bar and variable frequency speed adjustment system. The electric control, with PLC at its core, is a 3-stage system of up-position monitoring, field bus and frequency variable speed control. It causes not disturbance to the power grid, allowing a wider range of power voltage fluctuation and high power factor. The system is loaded with software to optimize the dig/cut curve and automatically optimize the hoist and dig power distribution. The system automatically troubleshoots, displays status, and calculates electric power. This system has the advantages of state-of-the-art technology, reliable operation; high transmission efficiency and low power consumption.WK-35 excavators are designed to be used in combination with mining trucks with a capacity of 172MT to 326MT.

Technical characteristics:

• Gear-rack crowding, powerful penetration, highly efficient;

• Gear transmission uses gears of high hardness surface for durability;

• Uses a planet reducer for the swing and propel mechanism;

• Propel has a high hand drive for added durability;

• Air release spring disk brakes.
