Abstract
An industrial vehicle including a lifting device, a hydraulic system having two or more pump motors that provide hydraulic flow to the lifting device, a load-handling device, and a second hydraulic system fluidly coupled to the main hydraulic system. The hydraulic system diverts the hydraulic flow from one of the pump motors to the second hydraulic system when an actuation of the load handling device is detected.
Claims20
An industrial vehicle comprising:
- a lifting device;
- a main hydraulic system having two or more pump motors that provide hydraulic flow to the lifting device;
- a load-handling device;
- and
- a second hydraulic system fluidly coupled to the main hydraulic system, wherein the main hydraulic system diverts the hydraulic flow from one of the two or more pump motors to the second hydraulic system when actuation of the load handling device is detected.
2 more elements
A hydraulic system for an industrial motorized vehicle, the hydraulic system comprising:
- a main hydraulic system having two or more pump and motor assemblies;
- a second hydraulic system fluidly coupled to the main hydraulic system;
- and
- a load sensing circuit that detects a change in pressure in the hydraulic system and diverts a hydraulic flow from one of the pump and motor assemblies in the main hydraulic system to the second hydraulic system.
1 more element
A method for managing a hydraulic system, the method comprising:
- combining a hydraulic flow from two or more pumps when a primary hydraulic function is requested;
- sensing a change in hydraulic load when an auxiliary hydraulic function is requested;
- and
- dividing the hydraulic flow from the two or more pumps when the change in hydraulic load is detected, such that a first pump continues to provide a hydraulic flow to the primary hydraulic function and a second pump simultaneously provides a hydraulic flow to the auxiliary hydraulic function.
