Claims

[Claims for Utility Model Registration] (1) A long main beam with a hoisted tool that removably engages with a lifting tool of a lifting machine, and a suspension fixed to both ends of the long main beam. A metal fitting, a plurality of lifting ropes each having a hanging hook at the tip and swingably suspended via the hanging metal fitting, and the long main body via a bearing fitting fixed to the inside of an adjacent part of the hanging metal fitting. A guide arm swingably suspended in the long axis direction of the beam, a plurality of guide springs elastically engaged with the hanging hook, and the guide springs are arranged symmetrically with respect to a vertical plane passing through the long axis of the long main beam. A lifting rope guide device is provided with a positioning device for freely guiding each shaft to a symmetrical position, and a lifting rope guide device is attached to the tip of the guide arm, and a swinging guide arm is installed between the guide arm and the long main beam. a telescopic cylinder, a drive device for the telescopic cylinder for swinging the guide arm fixed to the elongated main beam, and a remote control device for the lifting rope guide device of the drive source supply device provided in the operator's cab of the lifting machine. A pipe hoist with a drive source and control connection to a control device. (2) Claim 1, further comprising a plurality of swing-suppressing metal fittings that are vertically installed between the telescoping cylinders for swinging the guide arms on the lower surface of the long main beam and can freely come into contact with the body of the pipe to be transported. Pipe hanging equipment as described. (3) The pipe hoist according to claim 1 or 2, wherein a hoisting rope retaining spring is stretched between the guide spring guide of the hoisting rope guide device and the hoisting rope near the hook.
