Product Description:

WK series excavators are used for open-pit mines. They have been developed through a combination of years of successful experience in the manufacturing of mining shovels and the adoption of advanced technology in design, processing, and manufacturing from home and abroad. They are suitable both for stripping and excavating open-pit coal mines, iron mines and ferro-metal mines.

Our WK series excavators feature such state-of-the-art technology as three-dimensional imitation and definite circle analysis. They perform well and can be used effectively according to users’ requirements in combination with various haul trucks and crush stations for higher loading and lower production costs.

Our excavators’ electric system uses a rectifier/regeneration common 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. Our WK-55 excavators are designed to be used in combination with mining trucks with a capacity of 220MT to 363MT.

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.

Q:Disconnect to another panel?
Sorry, I'd like to help you but your question is too confusing. The way I read it is, the sub panel main disconnect is near or at the service entrance, which is 50 feet away. That's fine. You want to put in a transfer switch so you can transfer the power from the service to a generator to feed the panel. Nothing wrong with that, so long as you put the transfer switch between the panel disconnect and the panel. Distance does not enter the picture. I hope that helps.
