Abstract: The invention relates to a mobile work machine having a chassis (10) and with two front and two rear support brackets (20, 22). The support brackets can be displaced from a driving position close to the chassis into a support position by changing the base angles (α) thereof and/or can be telescoped by changing the lengths thereof between the end on the mounting side and that on the free end. In order to be able to automatically determine the support leg positions (Xc/Yc) in relation to the chassis (10), three transceiver units (S1/E1, S2/E2, S3/E3) related to the support legs are provided for transmitting and receiving run time or distance signals. Furthermore, a microprocessor-supported evaluation unit responding to the transmitted and received signals of the transceiver units arranged in pairs is provided, comprising a software routine for determining the support leg positions in a coordinate system (x/y) fixed to the chassis.

Abstract: A system for a loader stores a signal indicative of a desired inclination of an implement. Upon receiving an operator interface actuation signal, a controller transmits a signal to move the implement to the stored inclination. The controller further transmits a lift arm command signal to move a lift arm towards a lower limit of travel of the lift arm. The lift arm command signal is terminated after the controller receives a signal from a sensor on the lift arm indicating that the lift arm is near its lower limit of travel. After the command signal is terminated, the controller may transmit a second lift arm command signal to further move the lift arm.

Abstract translation: 用于装载机的系统存储指示工具的期望倾斜度的信号。 在接收到操作员界面致动信号时，控制器发送信号以将工具移动到存储的倾斜度。 控制器进一步传递提升臂指令信号，以将提升臂朝向提升臂的下行行程移动。 在控制器从提升臂上的传感器接收到信号后，提升臂指令信号终止，表示提升臂接近行程的下限。 在命令信号终止之后，控制器可以发送第二提升臂命令信号以进一步移动提升臂。

Abstract: The procedure, provides a simple and retro-fittable manner to align working equipment, mounted to a liftable and lowerable hoisting frame of a working machine in a tilting way to comply with required positions, wherein the working equipment is shifted via a tilting cylinder in other directions than the hoisting framing. The tilting cylinder is supplied with hydraulic oil from a hydraulic pump for the working hydraulic system by a direct-operated control valve, and secondary consumers of the working machine being supplied with hydraulic oil from at least one other hydraulic pump. Once the driver operates a triggering element, the two hydraulic connections of the tilting cylinder are also connected to the hydraulic pump for the secondary consumers by a switch-over valve activated by the control equipment, therefore shifting the tilting cylinder in the direction of the neutral position of the working equipment.

Abstract: A method and machine with an automated digging cycle is provided. The method includes moving an implement system of the machine through a work cycle, including interacting with a material. The method further includes sensing values associated with a bucket velocity parameter, such as bucket tip velocity, during interacting with the material, and controlling the velocity parameter via commands which control a sequence of bucket orientations whereby an implement system of the machine interacts with the material, responsive to the sensed values. The machine includes an electronic controller configured via a control algorithm to execute the automated digging cycle. A velocity based control system for an excavating machine includes an electronic controller configured to receive velocity signals from at least one sensor, determine a bucket tip velocity, and output control commands to move a bucket of the excavating machine through a material via a sequence of bucket orientations that is based on the determined bucket tip velocity.

Abstract: Automated bucking loading is achieved through the use of sensor feedback provided by pressure and extension sensors on hydraulic cylinder(s) to control the trajectory of the bucket to be loaded by a computer algorithm. Additional sensors may be used to provide further control of the loading cycle and of the vehicle operation. The structure and steps can be integrated with existing machinery or used on new loaders equipped with suitable control interfaces capable of taking computerized control of the vehicle's actions.

Abstract: The material loading machine supported on the ground surface is in combination with a return to travel assembly. The combination includes a material loading machine chassis, a work implement, and at least one lift arm supported by the chassis to pivot between an uppermost position and a lower most position while supporting the work implement. Actuators pivotally raise and lower the lift arm. A lift arm position control system automatically stops the lift arm in an uppermost position when it is raised upwardly and automatically stops the lift arm in a return to travel position when it is lowered. In the return to travel position the work implement is located safely above the ground surface so that the vehicle may travel without scraping the work implement on the ground surface.
