468) Pallet lifter

A below-the-hook lifting device that utilizes forks in its design and serves to take the role of forklift forks while utilizing the capabilities of a crane and/or hoist.  Generally, counterweighted at its top and attached via a bail and hook arrangement.

469) C hook

A device, generally attached to the hook of a lifting device via a bail, which "grabs" a coil of materials when inserted into the ID of that coil.  Derives its name from the physical appearance of the device which resembles the letter "C".  May utilize counter- balancing weights to add stability and balance in the lifting motion.

470) Lifting beam

471) Vacuum lifter

A lifting device utilizing the creation of vacuum to attach itself to an object via the use of an electric-powered extraction pump and sealed pads. Generally suspended from a hoist/crane, manipulator, balancer, or positioner.  Often attaches to the lifting mechanism by means of a bail and hook arrangement or is an integral part of the positioning and lifting mechanism.

472) Hook rotator

A motorized device that powers the rotation of the hook attached to the bottom block of a hoist. The hook on a bottom block generally rotates manually but due to the weight of a load and/or the need for controlled hook movement, this hook rotation is driven by a motor and gearing arrangement.

473) Laser

An acronym for light amplification by the stimulated emission of radiation.  Converts energy into laser light which in turn, can be used to control the direction and movement of material handling equipment.

477) Indentation type pressure gripping lifter

A lifter that clamps the load and supports it by indenting the load in areas in contact with the lifter.

478) Rated load capacity

The maximum load for which the equipment is designed by the manufacturer.

479) Structural lifter

A lifter which consists of one or more rigid parts for attaching the load to the lifting device.

480) Supporting lifter

A lifter that carries the load on rigid projections or weight bearing surfaces.
