Below-the-hook (BTH) devices are attachments that connect to the bottom end of the hoist chain or rope. They allow the operator to lift loads that cannot be lifted by a traditional hoist hook. Below-the-hook devices must be engineered by experienced designers in order to provide for the safe lifting of unbalanced loads or loads without an obvious pick point.
Types of Below-the-Hook Devices
Below-the-hook devices take many shapes and utilize many different technologies. Examples include:
Magnets
Slings
Spreader beams
Roll lifters
Clamps
Coil lifters
Grabs
Industry-Specific Below-the-Hook Devices
