  • Patent number: 5356260
    Abstract: A loading/unloading vehicle having booms and a bucket carried thereon such as a shovel loader, a wheel loader or the like vehicle detects that a true bucket-to-ground angle coincides with a preset angle after the vehicle starts automatic turning movement of the bucket. When the coincidence is detected, the automatic turning movement of the bucket is interrupted. Thereafter, a differential value between the true bucket-to-ground angle and the preset angle is determined, if any and then the bucket angle is corrected so as to allow the differential value to be reduced to zero. Consequently, the bucket is held at the preset angle after the bucket stops, even though the booms continue to be turned.

  • Patent number: 5338137
    Abstract: A pair of tracks having spaced cutouts formed along the longitudinal extent thereof are mounted vertically on opposite walls of a compartment such as the interior of a truck or other transportation vehicle. A beam assembly is formed by a pair of channel members and a beam member in which the channel members are slidably supported in telescoping relationship, the channel members having limited longitudinal movement relative to the beam member. One end of each of the channel members protrudes from the beam member and has a spring actuated latching device attached thereto. The effective length of the assembly can be adjusted by slidably positioning the channel members relative to the beam member to bring the latching devices into contact with the opposing tracks with such latching devices being selectively fitted onto flanged portions of the track and into a pair of opposing track openings so that they latch onto the track.

  • Patent number: 5234298
    Abstract: An improved system for quickly securing a load to a flat bed vehicle. Rotatable main shafts are secured on opposite sides of the load with each of the main shafts having a gear box. An access shaft couples the two main shafts together through worm gearing so that actuating the access shaft from either side of the truck actuates both main shafts. This causes the main shafts to rotate in opposite directions and pulls the binding tight across the load. A ratchet may be provided on the main shafts to also secure a position of the main shafts and allow effective motion in one direction only. The binding may be removed from the load by releasing the ratchet and rotating the main shafts in an opposite fashion.
