A below-the-hook attaching device which, using a jaw-like scissor gripping action, clamps or locks onto a piece of material. This device is attached to the hook of a hoist or the end effector of a manipulator and usually is used to pick up sheets of material such as wood or metal.
47) Contained load
A pallet load of items or cartons (either identical or mixed in terms of size or contents).
48) Bin storage
May be considered a special case of shelving. The horizontal opening would typically be much narrower than that found in shelving and would have a vertical restraining member across the lower face of the bin opening.
49) Counterbalanced truck
An industrial truck that is weighed at the rear of the truck to prevent (counter) any forward tipping of the truck that could occur when lifting a load.
50) Ball transfer table
Another form of gravity conveyor that utilizes balls rotating in sockets over which the load is passed and thereby easing effort of movement. Another form of gravity conveyor that utilizes balls rotating in sockets over which the load is passed and thereby easing effort of movement
51) Belt driven live roller conveyor
A form of powered roller conveyor which is distinguished by a drive motor connected to a wide, flat belt which contacts the underside of the roller surface causing the rollers to rotate and move the load. The load is place directly on the belt which is supported by the rollers.
52) Chain conveyor
A form of powered conveyor used to transport heavy unit loads such as pallets and industrial containers. These conveyors can be single or double chain strand in configuration. This chain is not only the driving force but it is also the part which comes in direct contact with the load and provides friction which pulls the load forward. In some cases, free rollers on either side of or between the chain provide additional support to the load. Short sections of double strand chain conveyors are a common means of transferring loads at right angle to/from another straight section of roller conveyor.
53) Block stacking
The action of putting objects into a block pattern in a floor storage area, usually more than one tier in height.
54) Chute conveyor
The chute conveyor is the simplest example of gravity operated conveyor. Not unlike a child's sliding board, unit simply slides down a straight or spiraling metal or plastic chute to it ultimate destination.
55) Auto ID
Automatic identification. A system which utilizes bar codes and other symbologies to provide information.
Wheeled devices, generally made from plastic and/or metal, utilized to move items within a warehouse, distribution center or manufacturing facility. Carts can be equipped with drawers, bins, trays or flat surfaces to secure items for transport and storage. Carts utilize casters as well as pneumatic and semi-pneumatic wheels. See also Trays .
57) Cantilever rack
A rack, utilizing "arms" cantilevered from columns, used where there is a need for a full clear shelf that can be loaded from the front without obstruction from rack support uprights.
58) Box girder crane
An overhead traveling crane that utilizes a "box" configuration in fabricating the bridge girder. This box girder design incorporates a four-sided box with a running surface plate for the hoist trolley attached to the bottom of the box. The advantage of the box girder is that it possesses greater loading capabilities and is able to span greater bridge distances. Generally utilized in pairs with the hoisting mechanism operating on rails attached to the top of each box girder.
59) Column mounted jib crane
Also referred to as a "pillar-supported" jib crane. The jib is attached to a self-supporting floor mounted or floor to ceiling mounted mast. A column mounted jib crane may also be supported vertically by a structural column of the building structure itself.
60) Cantilevered gantry crane
A single or double legged gantry crane designed so that the bridge girder extends over the leg or legs so as to form a cantilevered configuration. Such a design increases the loading surface of the bridge girder therein increasing the reach capabilities of the gantry crane.
