Types of Below-the-Hook Devices
Spreader Beams:
They use two or more lifting points instead of one singular lifting point — the weight of the load is distributed evenly across the beam, which eliminates the stress on a single lifting point. Reduce the chances of load tipping, sliding, or bending. Can be designed in fixed dimensions or can be engineered to allow for incremental adjustment of the sling angle, and the length of the beam itself, for off-center load adjustments.
Coil Lifter / C-Hooks:
These devices enable the lifting of a coil through its inner diameter, in a vertical or horizontal orientation, with a motorized hook rotator attached to the bottom of a hoist for additional load control.
Vacuum Lifters:
Vacuum tube lifting systems use suction to grab the load, support, lift and lower the load without the use of a hoist, all by means of a single operator control.
