A built-in communicating passage in the counterbalance valve balances flow and pressure to suppress excavator mistracking without extra circuits.
Controller-coordinated pump and accumulator flow limits actuator power by work mode, cutting fuel use without sacrificing excavator workability.
Reduced compressor speed lowers discharge pressure before exhaust release, cutting vehicle pneumatic venting noise without added silencers.
Multiple small motors and pumps are switched by load demand to cut starting current, reduce oil waste, and extend battery runtime.
A coiled mesh filter uses radial spring force to secure around a cylindrical hydraulic component, saving space and weight in brake systems.
