WYD260/WY260 Hydraulic Excavator is a large-scale open-pit mining equipment developed by our company, and it can be driven by both electric motors and diesel engines. This equipment offers high flexibility and relatively low investment, making it suitable for open-pit mines that frequently require relocation.
It is primarily utilized for the stripping and mining operations in large-scale open-pit mines and serves as upstream supporting equipment for mining dump trucks or self-moving crushing stations.
Independent closed rotary circuit: Simplifies the circuit by eliminating the need for the main pump to be shared with the working device through valve control. Rotary braking energy can be fed back to the transfer case and other pumps.
Adoption of electro-hydraulic proportional control technology: Enhances the work efficiency of the entire machine and reduces driver fatigue.
Implementation of limit power control: Enables each pump to fully utilize the motor's power, thus reducing energy loss.
Energy regeneration in the bucket rod and boom: Utilizes the weight of the bucket rod and boom to save energy by not requiring the main pump to provide power when lowering the boom and bucket rod.
