摘要： An improved Z-bar linkage for wheel loader machines for maneuvering an implement such as a bucket or pallet forks may include lift arms pivotally connected between an end frame of the machine and the implement, a tilt link pivotally connected between the implement and a tilt lever that is pivotally connected between the tilt link and the lift arms. Lift cylinders may rotate the lift arms to raise and lower the implement, and a tilt cylinder may drive the tilt lever and tilt link to rotate the implement between a dump position and a racked position. Ratios of the lengths of these kinematic elements are provided such that the good performance with one implement, such as bucket, does not result in poor performance with another implement, such as the pallet forks.

摘要： A machine configured to prevent unintentional motion in a linkage pivotally connected to a frame may include a first hydraulic actuator connected to the linkage and a second hydraulic actuator connected to the linkage. The machine may include a sensor and an electronic control module in communication with the sensor. The electronic control module may be configured to close a valve of the first hydraulic cylinder and/or cancel an actuation command to one of the first hydraulic actuator and the second hydraulic actuator in response to the electronic control module determining unintentional motion of the linkage has occurred based on the sensor.
