61) Spreader beam

A below-the-hook lifting device that utilizes two or more hooks (attaching devices) located along a beam and the spreader beam attaches to the hoist by means of a bail.  The spreader beam is used to handle long or wide load and serves to "spread" the load over more than one lifting point. Often used in conjunction with slings.

62) Bottom block

The device at the bottom of a hoist's lifting medium (chain/wire rope) through which the medium is reeved and supports the hook and/or an attachment.  May be stationary or rotating depending upon the requirements for the piece of lifting equipment.

63) 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.

64) 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.

65) Lifting beam

A solid or fabricated metal or wooden beam, suspended from a hoist/crane or from forks of a forklift, designed to provide multiple lifting points.  The lifting beam enables the user to attach the load at more than one point therein securing and controlling the load's movement.

66) 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.

67) Mechanical lifter

A lifter composed of two or more rigid parts that move with respect to each other to attach the load to the hoisting device. All movements of this grab as it attaches to the load are manually actuated.

68) 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.

69) Structural lifter

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

70) Supporting lifter

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

71) Friction type pressure gripping lifter

A lifter that clamps the load and supports it by friction without causing permanent deformation of the load.

72) Sheet lifter

Usually a below-the-hook (hoist or balancer) material handling device that utilizes two "claws" that grab a piece or pieces of sheet metal or wood.  These claws are "squeezed" by means of a ratchet and turning wheel and wrap around the sides of the sheet.  A lip on the lower portion of the claws prevents the sheet from falling out of the lifter.  The sheet lifter is attached to the lifting device by means of a bail at the top of the device.

73) Carousel

Carousels are a technology used to store items for eventual picking or retrieval. There are two primary types of carousels and one related technology, all of which operate under some form of computer control. Since the late 1990s, carousels have been placed under the more general category of AS/RS. See also Horizontal Carousels , Vertical Carousels ,  Vertical Lift Modules and/or AS/RS .

74) Four way pallet

A pallet which, by its construction, allows forks of a lift to enter the pallet from both sides and ends.

75) Tote

A container generally used for order-picking and shipping of items.  Usually small in size and easily moved by hand or other lifting devices and designed to be durable and reusable.
