摘要: Hydraulic actuators and/or other parameters on a work attachment for a skid steer loader are controlled with a wireless remote control kit. The kit includes a manual input device and transmitter mounted to the skid steer loader and a receiver on the work attachment that communicates with the transmitter. The receiver directly couples the manual input from the vehicle operator to the solenoid valves that control hydraulic flow to the hydraulic actuators on the work attachment, without processing by an electronic controller. The response of hydraulic actuators directly corresponds to the manual input provided by the vehicle's operator. The manual input device, transmitter module and the independent power source may be self-contained in a module that is attachable and detachable to skid steer loader. The module can be removed and transferred along with the attachment such that the attachment is usable with different skid steer loaders.

摘要: Hydraulic oil supplied from pumps (12),(13) to an attachment actuator (60) is controlled by attachment control valves (27),(28). Hydraulic oil supplied from pumps (12),(13) to other actuators (52),(54),(56),(58) is controlled by other control valves (21) through (26). Control conditions for operating the attachment actuator (60) alone and control conditions for operating the attachment actuator (60) simultaneously with any of the other actuators (52),(54),(56),(58) are discriminated by the pilot pressure sensors (32),(34),(36),(38). Control characteristics of the attachment control valves (27),(28) are controlled by a controller (43) based on the discriminated control conditions.
