Latest Patents

Shirato’s listed patent is titled “Construction machine.” It describes a machine with hydraulic actuators powered by two hydraulic pumps, including actuators that drive a front work implement. A controller uses the distance between the implement and a target construction face, along with an operator’s input, to manage the pumps and solenoid valves.

The controller calculates an upper speed limit for one actuator based on the available flow from the second pump after accounting for the flow supplied to another actuator. It then limits the actuator’s requested speed accordingly and controls the pump and valves to achieve the resulting target speed. This approach is intended to coordinate hydraulic flow while supporting controlled implement operation. Shirato is credited with 1 patent.
