Abstract
An apparatus is provided to shorten and/or fasten flat belts or straps for wrapping and hoisting a load. The apparatus includes a vertical base plate having a crane lug located in its upper portion. Also, at least three deflectors with free ends are mounted in spaced apart relation on the plate so as to project generally perpendicularly therefrom. The free ends of the straps or belts are inserted into the apparatus and pulled between and looped about the deflectors in a meandering fashion to affix the belts to the apparatus before hoisting the load.
Claims13
Apparatus to shorten and/or fasten flat belts for wrapping and hoisting a load, comprising:
- (a) a base plate being adapted for use in a vertical orientation and having a crane lug defined in an upper portion thereof, said base plate having an extended surface and an edge surface;
- and
- (b) a plurality of elongated deflector elements having free ends for being at least in partial removable contact with the belts with said free ends for receiving the belts, and with said deflector elements being attached at ends opposite said free ends to said base plate in spaced apart relation to one another, said deflector elements projecting from said base plate and adapted to have inserted past said free ends thereof and pulled therebetween and deflected and looped thereabout in a meandering fashion the belts to fasten the belts to said deflector elements before hoisting the load;
- and
- means for securing a portion of a belt disposed away from the meandering portion of the belt, the load for being disposed between;
- the portion of the belt disposed away from the meandering portion of the belt secured by said securing means and
- the meandering portion of the belt meandering about said deflector elements;
- said plurality of deflector elements including at least three deflector elements including at least three deflectors;
- and
- said deflector elements projecting generally perpendicularly from the extended surface of said base plate.

- and
- said deflector elements projecting generally perpendicularly from the extended surface of said base plate;
- and
- wherein a middle one of said deflector elements located in a space between upper and lower ones of said deflector elements is guided for movement in a plane which intersects a plane through the upper and lower deflector elements.
