SURVEY SWING

摘要

A survey sling includes a sling coupled to a pole hook. A load-bearing pole is passed through a channel in the pole hook and into a central aperture. The pole hook is rotated so that the inner surfaces of the central aperture grip the pole hook. The load-bearing pole can then be ergonomically transported by lifting the sling. To disengage the pole hook from the load-bearing pole, the pole hook is rotated to distance the inner surface from the pole.

主权项

1. A device for ergonomically transporting a load-bearing shaft, the device comprising:
a sling attachment section adapted to couple with a sling; a shaft engagement section adapted to engage a shaft, the shaft engagement section comprising a shaft receiving aperture defined by an inner surface, wherein the inner surface includes a first edge and a second edge that is opposite the first edge, wherein the first edge of the inner surface is adapted to frictionally engage a first portion of an outer surface of the shaft, wherein the second edge of the inner surface is adapted to frictionally engage a second portion of an outer surface of the shaft that is opposite from the first portion of the outer surface of the shaft, and wherein the frictional engagement between the first edge and the shaft and the second edge and the shaft is sufficient to lift the shaft when the device is lifted.
