    • A method and apparatus are disclosed for controlling the cross slope angle cut by the blade (114) of an articulated frame motorgrader (100) operated in the crabbed steering mode wherein the articulation angle (A) of the motorgrader frame is sensed and used to calculate the blade angle relative to horizontal required to maintain a desired cross slope angle. The blade angle is sensed and controlled such that the sensed blade angle is maintained substantially equal to the calculated blade angle. The blade angle calculation is performed using the equation: tan B = (sin (A+R))(tan L) + (cos (A+R))(tan C) where B is the required blade slope angle of the blade (114) relative to horizontal; A is the sensed angle of rotation of a steering unit (106) relative to a drive unit (102), the steering unit (106) and drive unit (102) making up the motorgrader (100) articulated frame; R is the sensed angle of rotation of the blade (114) relative to the steering unit (106); L is the sensed direction of travel slope angle of the motorgrader (100); and, C is the desired cross slope angle which is entered by an operator of the motorgrader (100).

    • The invention relates to a blade controller of a bulldozer which can level or grade the ground smoothly, highly accurately, efficiently and quickly without being affected by pitching of the tractor main body of a bulldozer and by a soil moving quantity of the blade. The controller includes at least two light receptors (2, 3) disposed in a longitudinal direction of the tractor main body (1) in the spaced-apart relation, detecting the optical reference surface (6) formed by a projector (4) and outputting the respective level signals, and a blade controller (13) for controlling a hydraulic valve actuator (14) operating the blade (8) of the bulldozer in accordance with the level signals. Each light receptor (2,3) can have a three-dimensional position detection function for detecting a three-dimensional position of the tractor main body (1) and in this case, the blade controller (13) controls the hydraulic valve actuator on the basis of an output signal from a position measuring controller (23) for determining the work-done data of the work upon receiving the level signal outputted from each light receptor.

    • A method and apparatus are provided for controlling the working depth of a bucket for an excavating machine (100) having an outreach boom (102) which is pivotally attached at one end to the machine, a downreach boom (108) pivotally attached to the opposite end of the outreach boom, a digging bucket (112) pivotally attached to the end of the downreach boom opposite to that to which the outreach boom is attached, and hydraulic power cylinders (116, 118, 120) for moving the pivotally interconnected elements. A laser beam (126) is projected at a reference height and a beam sensor (128) mounted on the outreach boom (102) of the machine detects the beam (126) by means of a plurality of individual sensor locations. The angular orientation of the downreach boom (108) relative to vertical is detected by an angle sensor (134, 136, 138, 140, 142) and a microprocessor controller (150) connected to the beam sensor (128) and the angle sensor (134, 136, 138, 140, 142) repetitively defines, as a function of the angular orientation of the downreach boom (108), one of the plurality of individual sensor locations (C1-CX) as an on-grade sensor location. The microprocessor controller (150) compares the defined on-grade sensor location to the sensor location having detected the laser beam to generate an outreach boom adjustment signal representative of the movement of the outreach boom (102) which is required to maintain the bucket (112) on-grade as the downreach boom (108) is pivoted with respect to the outreach boom (102).

    • An excavator wheel (15) provided with an annular array of peripheral scoops (16) is rotated about a horizontal axis while the wheel is moved along the terrain alongside a railroad track. The axis of rotation of the wheel is positioned selectively to be disposed within the range of perpendicular to the longitudinal extent of the track to substantially parallel thereto, whereby the scoops excavate a ditch correspondingly in the range of a narrow trench having a width equal to the transverse extent of the scoops to a wide ditch having a profile corresponding generally to the circumference of the wheel. The wheel is carried on the distal end of a boom (20) having the opposite end mounted to a wheeled support. The wheels are carried on suitable trucks (53) adjustably connected to the support to permit leveling of the support. In one form, the wheel is reversibly rotated and provided with double-ended scoops to permit excavation in either direction of rotation of the wheel. In one form, the wheel is swingable about a vertical axis (18) on the distal end of the boom so as to be positionable on either side of the boom in use. The wheeled support, in one form, is provided with a laterally opening recess (60) for accommodating the wheel in a storage position. The excavated material, in the illustrated embodiment, is conveyed from the excavator wheel by conveyor belts for desired disposal selectively at either side of the railroad track or to a suitable hopper car. The excavator wheel is arranged to drop the excavated material downwardly from the scoops at an upper position onto a subjacent conveyor belt for disposal.
