Spreader attachment bars can also be attached to cranes. A center hold accepts a hook and allows the attachment to be suspended from a cable.
These attachments are adjustable. Model size refers to the maximum extension of the unit. For example, the 30 foot forklift spreader bar actually extends anywhere from 20 to 30 feet. The 12 foot model extends between 8 and 12 feet, and the 20 foot model extends between 12 and 20 feet.
The shorter the extension of a bar, the more its weight capacity increases. For instance, a 30 foot bar extended to only 20 feet will support 20,000 pounds. At 25 feet, its capacity drops to 18,000 pounds, and at 30 feet, its capacity is only 15,000 pounds.
Crane hook capacities are less, but still sufficient to make the device a practical crane attachment suitable to a wide range of operations.
