A crane similar to an overhead crane except that the bridge for carrying the trolley or trolleys (with lifting device) is rigidly supported on two or more legs running on fixed rails or other runway.
A stationary or fixed crane that utilizes a cantilevered bridge (girder) supported from a stationary vertical support. The jib crane generally utilizes a lifting device (hoist) that is mounted on the horizontal boom (jib).
Automated Electrified Monorail describes a conveying system which consists of monorail track, track mounted electrification, individually powered vehicles, a supporting structure, a control system, lifts, switches and turntables as are necessary.
An attachment, such as grippers, spraying nozzles, welding tooling, and measuring devices, connected to the mechanical portion of a manipulator, balancers, positioner, or robot. Generally designed to fit a certain need and or lifting situation but is not restricted to single task.
Also known as "tractors". Used solely to pull a string of unit load trailers and have no lifting capability. These can be operator driven or automatic/guided path. See also Tugger AGV .
An overhead traveling crane whose horizontal travel is powered manually or by the operator. Often work station cranes are push type cranes. This crane may or may not utilize powered hoist or lifting mechanisms.
A lever operated manual device used to lift. lower, or pull a load and to apply or release tension. Utilizes a ratchet and pawl mechanical configuration to incrementally raise or lower a load or to apply or release tension.
A hoist that utilizes wire rope as the lifting medium. Often powered electrically or pneumatically. This lifting device is made up of a rope storage drum, motor(s), gear box and braking system and is suspended from a monorail or bridge beam(s) by means of a trolley. May also be mounted in a staionary manner. Manual wire rope hoist are generally referred to as "pullers" and operate utilizing a ratchet and pawl tensioning technology.
A device used for moving and storing freight. It is used as a base for assembling, storing, stacking, handling, and transporting goods as a unit load. Commonly, it is about four feet square and is so constructed to facilitate the placement of a lift truck's forks between the levels of a platform so it may be moved easily.
A lifting and horizontal movement device mounted on a "bridge" of one or more horizontal girders (bridge girders) which are supported at either end by trucks (end trucks). These trucks are attached at right angles to the girders and move on runways which are attached to a building's columns, overhead trusses, frames, or via a free standing system of columns.
A form of wall mounted or column mounted jib crane that utilizes a vertical pivoted member and a bridge or mast that extends at right angles to the pivoting member. This design adds the advantage of having the jib boom at the highest hook lift , thus taking advantage of an entire building height.
The standard pallet in Europe. It is 1200 mm by 800 mm in dimension and has a wood block design between the top and bottom permitting four-way or four-sided entrance by lifting forks. Although other sizes exist in Europe, they are not nearly as prominent as the Euro-pallet.
Palletizers are special machines capable of building a complete unit load on a pallet. Although the most common application is for cases, some palletizers can also handle sacks and bags. A less common palletizer application would be for special products such as sheet stock. There are two general methods employed for automatically building a full pallet. One makes use of a fixed position or overhead gantry robot with end effectors suited to the individual loads, such as vacuum lifts or a gripper. The other method employs more complex mechanisms for forming pallet layers off line, one at a time, and then shifting or transferring each successive layer onto the pallet as it is lowered via a lift/lower table.
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 .
