Description

  The present invention relates to a tube suspension gripping device, and more particularly, to a tube suspension gripping device used when lifting or hanging a steel pipe or other various types of tubes.

  For example, when pipes such as steel pipes are laid in piping work, the pipes need to be suspended. In particular, the outer peripheral surface of the steel pipe used for piping work is coated with anti-corrosion paint, so that when suspending the steel pipe, a nylon hanging rope, not a metal sling wire, should be used to prevent the paint from being damaged. In general, the suspension rope is wrapped around the outer peripheral surface of the steel pipe, and the suspension rope is lifted or lowered using a heavy lifting machine such as a crane.
