  • Vehicle for manipulating pipe
    Patent number: 4966290
    Abstract: A vehicle for manipulating large diameter pipe includes a vehicle frame assembly which supports an auxiliary pipelayer frame. The pipelayer frame supports various components for manipulating the pipe, including a boom arm and a fluid cylinder for raising and lowering the boom arm. During transportation of the vehicle, certain components must be removed from the vehicle to make the vehicle conform to width and height restrictions. Normally, the boom arm and the fluid cylinder would be removed. The subject invention provides for storage of the fluid cylinder on the vehicle during transportation, without the necessity to disconnect fluid lines. Considerable time and effort is saved during dis-assembly and re-assembly of the vehicle components.

  • Limit control for an operating member
    Patent number: 4427026
    Abstract: An adjusting mechanism (92) is provided between a valve spool (62) and a valve actuating lever (26) whereby with the lever (26) locked in a selected position, the mechanism (92) is manipulated to move an element (99) carried by the valve spool (62) into alignment with an indicator (110) that has been predetermined to be the selected setting of the valve. With the element (99) aligned with the indicator (110), the mechanism (92) is locked so that the valve spool (62) is in the selected setting when the lever (26) is in the selected position. A lock-down apparatus (70) is provided for use in locking the lever (26) in the selected position while the adjusting mechanism (92) is being manipulated.

  • Adjustment method pipelayer control system
    Patent number: 4301834
    Abstract: An adjusting mechanism (92) is provided between a valve spool (62) and a valve actuating lever (26) whereby with the lever (26) locked in a selected position, the mechanism (92) is manipulated to move an element (99) carried by the valve spool (62) into alignment with an indicator (110) that has been predetermined to be the selected setting of the valve. With the element (99) aligned with the indicator (110), the mechanism (92) is locked so that the valve spool (62) is in the selected setting when the lever (26) is in the selected position. A lockdown apparatus (70) is provided for use in locking the lever (26) in the selected position while the adjusting mechanism (92) is being manipulated.
