  • Publication number: 20240068197
    Abstract: A loader can include a lift arm structure coupled to a frame. The lift arm structure can move between a fully-lowered position and a fully-raised position and can include a lift arm and a connecting link. A first end of the connecting link can be pivotally coupled to the frame at a first pivot point and the lift arm can be pivotally coupled to a second end of the connecting link a second pivot point. The lift arm structure can further include a lift actuator configured to pivot the lift arm about the second pivot point and an extension actuator configured to pivot the connecting link about the first pivot point. The extension and lift actuators can be controlled to move the lift arm along a variety of travel paths between any two points within a lift envelope of the lift arm structure.

  • Publication number: 20230279641
    Abstract: A control device for a power machine can be configured to receive a request to initiate a power burst mode for the power machine, wherein the power burst mode defines one or more operational parameters for increasing an amount of power used by at least one of the plurality of electrical actuator. The control device may receive data associated with one or more operational conditions of the power machine and assess a power burst constraint associated with the power burst mode. In response to the power burst constraint being satisfied, the control device may control power to at least one of the plurality of electrical actuators according to the one or more operational parameters of the power burst mode.

  • Publication number: 20230193592
    Abstract: A control system is provided for a first power machine having a first actuator and a second power machine having a second actuator. The first power machine includes a first user input device. Aa first user input corresponding to a power machine operation can be received via the first user input device and a control mode for controlling the execution of the power machine operation can be determined. Controlling the execution of the power machine operation can selectively include: in a local control mode, controlling the first actuator to execute the power machine operation with the first power machine; and in a remote control mode, controlling the second actuator to execute the power machine operation with the second power machine.
