Abstract: Deaeration of the high pressure oil chamber of a hydraulic tensioner takes place though a helical orifice formed by opposed flanks of the threads of a threaded hole in the tensioner housing and the threads of a screw inserted into the hole. The opposed flanks are maintained in spaced relationship by a force exerted by a spring washer disposed between the head of the screw and a surface of the tensioner housing surrounding the opening of the threaded hole. The flank of the thread of the hole that forms part of the boundary of the helical orifice can have a concave curvature in order to increase the aperture of the air flow path. A groove in the surface surrounding the opening of the threaded hole prevents the washer from sealing off the flow of air. This groove is disposed with its exit end at a level above its entry end.

Abstract: A crane includes a limiting device to limit a raising/lowering angle of the mast during suspending work to be equal to or less than an upper limit angle which is less than a value of the raising/lowering angle when the mast extends vertically; a release device into which a release instruction for causing the limiting device to release the limitation on the raising/lowering angle of the mast is input; and a first detection section adapted to detect that the mast support device is at an overhanging position where the mast support device pushes up and sets the mast in the work posture. The limiting device is operable whenever the first detection section does not detect that the mast support device is at the overhanging position, even if the release instruction is input into the release device, to prohibit the mast from being tilted rearward beyond the upper limit angle.

Abstract: An extendable beam measurement system includes a support; a beam mounted on the support and movable with respect to the support along an axis of movement; a series of sensory points mounted along either the beam or the support in an orientation that is not parallel to the axis of movement of the beam; and a sensor attached to the other of the beam or the support in a direction that crosses the series of sensory points at different positions during movement of the beam along said axis. The sensor generates a first signal varying as the beam is moved along the axis to thereby provide a signal indicating the position of the beam with respect to the support. The system is useful on an outrigger for supporting a crane. Optionally the system can provide a second signal indicative of whether a jack on the outrigger is contacting a support surface and supporting the crane.
