Precise combined flow control: when the electric control of the bucket rod realizes the compound action, each pump power is controlled individually to precisely meet the flow rate needed for the action.

Return oil throttling control: the return oil from the rod chamber of the cylinder when the bucket rod is retracted is returned to the oil tank through an independent spool valve to reduce the back pressure.

Bypass cut-off control: bypass cut-off spool closes the center oil circuit of the multi-way valve in advance, so that the pump flow completely enters the cylinder work.

Intelligent monitoring of charging: standard equipped with 2 national standard charging ports, support DC fast charging. At the same time, intelligent monitoring of the charging status, optional high-power split-type, integrated DC fast charging pile, a single charge can be filled in 1.5 hours.
