摘要： A method for providing a machine operator with an augmented reality view of an environment includes determining a location and orientation of a vehicle. An eye position and gaze of an operator of the vehicle are also determined. Job information to be displayed to the operator of the vehicle is determined based on the location of the vehicle and the orientation of the vehicle. The job information is displayed to the operator based on the eye position and gaze of the operator of the vehicle. In one embodiment, environmental features that can be seen through the windscreen are determined. The job information displayed to the operator is modified based on the environmental features.

摘要： A pipe handling apparatus has a frame, a boom pivotally connected to the frame so as to be movable between a first position and a second position, an arm extending outwardly of the boom when the boom is in the second position, a gripper affixed to the end of the arm opposite the boom, a first line having a first end affixed to the boom, a second line interconnected to an opposite end of the first line and connected to the frame, and an actuator interconnected to the first and second lines. The actuator changes an angular relationship of the first and second lines so as to selectively tension the lines. The second line includes a first cable offset from linear alignment with the first line and a second cable extending in angular relationship with the first cable.

摘要： A tractor includes booms, lift cylinders, a hitch, dump cylinders, a magnetic valve, a speed-up circuit, and a speed-up restricting arm. The lift cylinders swing the booms upward and downward by an operating oil being supplied thereto. The hitch is provided to the booms to allow an implement to be attached thereto. The dump cylinders swing the implement upward and downward by the operating oil being supplied thereto. The magnetic valve switches between supplying the operating oil to the dump cylinders and supplying the operating oil to a grab cylinder provided in the implement. The speed-up circuit is able to perform a speed-up operation for increasing the flow rate of the operating oil supplied to the magnetic valve. The speed-up restricting arm is arranged near the speed-up circuit. The speedup restricting arm is brought into contact with a contact member attached to an input member for switching an operation of the speed-up circuit, to thereby restrict the speed-up operation, so that a speed-up of the grab cylinder is prevented.
