<p>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.</p>
