A component production method includes: a step of binding a long frame by a plurality of support devices arranged along the frame; a step of measuring, with a distance sensor, a distance to the frame supported by the plurality of support devices; a step in which, based on frame shape data prerecorded in a memory, the support devices move support positions where the frame is supported so that a calculated radial position of the frame being supported by the support devices matches the data about the frame shape; a step of fixing the frame in a state in which the data about the frame shape matches the radial position of the frame; and a step of performing a hole-making operation on the fixed frame.

A method of gripping a substantially planar workpiece while providing compensation for variations in thickness is described. During the process, the workpiece is overdriven into a clamping member before clamping force is applied, and the positions of the clamping member before and after application of the clamping force are measured. These measurements are then used to control a compensating movement of the tooling table and optionally a final lift of the conveyance rails.

Modular carriage for varying spacing between ends of polymer pipe during fusion. The modular carriage includes a fixed jaw; an inner movable jaw; an outer moveable jaw and a plurality of guide rods. The fixed jaw being adapted for tool free engagement with the terminal ends of the plurality of guide rods. A carriage cylinder is associated with at least two of the guide rods and mounted for reciprocal travel along the length of its associated guide rod. The movable jaws being adapted for tool free engagement with at least two carriage cylinders for reciprocal travel therewith. A combined hydraulic cylinder/guide rod includes a guide rod with an integral guide rod piston, a cylindrical tube, and a guide rod gland on each end of the cylinder tube.

The present disclosure is related to a hold-down for a cable tray. The hold-down may be configured for high-wind situations. The hold-down includes a support clamp for clamping onto a support, and a hold-down arm for holding the cable tray on the support.

A clamp comprises first and second clamp halves, each comprising an elongate object receiving portion and a portion of a clamp retention mechanism. The first and second elongate object receiving portions are sized and shaped to cooperatively hold an elongate object at a desired position when the first and second clamp halves are fastened together. The first and second portions of the clamp retention mechanism are sized and shaped to (a) engage each other when the first and second clamp halves are moved towards each other in a first direction, (b) fasten the first and second clamp halves together without requiring use of a tool to engage the retention mechanism, and (c) disengage from each other when the first and second clamp halves are moved away from each other in a direction orthogonal to the first direction to unfasten the first and second clamp halves without use of a tool.

A retrievable shaft locking mechanism for axial and rotational locking on smooth round shafts with a lever providing tensioning of the clamping ring and vectorially supporting a clamping action through a horizontal dowel pin.
