An apparatus for lifting, maneuvering, winding or unwinding reels comprising a pair of devices having an elongated retractable frame having a first end and a second end which are adjustable relative to one another; a first crossbar having two opposite ends, the first crossbar being mounted to a first end of the elongated retractable frame; a second crossbar having two opposite ends, the second crossbar being mounted to a second end of the elongated retractable frame; a first roller carrier mounted on the first crossbar; a second roller carrier mounted on the second crossbar, parallel to the first roller carrier, wherein the roller rotates axially about the roller carrier; and a means for adjusting the first and second end of the elongated retractable frame relative to one another so that the first and second ends of the elongated retractable frame are moved closer together and further apart.

Devices for lifting, maneuvering, winding and unwinding reels

A hollow cylindrical tube having an outer surface coated with one or more inks is provided, each ink encapsulated in capsules that rupture under one or more specific loading conditions to display a visually perceptible color. The tube may be used to determine the load capabilities of the tube, to optimize the tube construction and to determine load magnitudes of windable materials and/or the winding process.

Load indicating tube and method

The present invention relates to a device or a pair of devices for lifting, maneuvering, winding or unwinding reels, each comprising a center retractable member having an adjustable length; a first and second angularly-oriented vertical support bar, each pivotally mounted, at its proximal end, on opposite ends of the center retractable member, wherein the first and second angularly-oriented vertical support bars are pivotally joined to each other at their distal ends; a reel support member mounted on the joint of the first and second angularly-oriented vertical support bars, wherein the reel support member is adapted to removably by received by the bore of the reel; and a means for adjusting the length of the center retractable member, thereby moving the reel support member upward and downward, respectively.
