The high-end excavator supply system operates pilot valves,which are easier to operate and have better coordination.At the same time, to improve the comfort of operation, the angle of the single pilot valve control lever is increased.

Customized development of duplex gear pumps for high reliability and longer service life.

Customized and developed electronic control walking shift valve for high-end excavator supply system,which works more stably and reliably.

Hydraulic pilot is designed separately to add a filtration system.Ensure the cleanliness of the pilot oil circuit and effectively solve the problem of stuck pilot handle and multi way valve pilot valve core.

To ensure the reliability of the power shift walking system a separate oil inlet and return filtration system is designed and added.

Specially designed cooling system for tropical climate: Adding hydraulic oil radiators and insulated rubber plates effectively solves the problem of high temperature in hydraulic systems, making the entire hydraulic system work more stable and reliable.

The H-type support legs and side-shifting excavating device make it more suitable for operation in tight urban spaces, expanding the excavation range.
