16) Rollover capacity

The maximum amount of single axle load which may be rolled over the platform surface when the lift is in its fully closed position.

17) Scissors lift

A raising/lowering device that is supported or stabilized by one or more pantograph leg section.

18) Vertical creep

Extremely slow speed movement of a scissors lift that is the result of normal, internal leakage of fluid control valves.

19) Vertical travel

The difference between the fully raised height of the platform deck and the fully closed height of the platform deck on a scissors lift.

20) End/side axle load capacity

The maximum amount of single axle laod (in the case of rolling loads) which may be applied to the loading edge of a lift platform (end or side) when the lift is in its raised position.

21) Compression molded pallet

Plastic material is placed in an open mold, which is then closed.  Pressure is applied as the mold halves come together (usually in a vertical configuration), forcing the plastic material to flow and fill the cavity.

22) Conveyor

A horizontal, inclined, or vertical device for moving or transporting bulk material, packages, or objects in a path predetermined by the design of the device, and having points of loading and discharge, fixed or selective.

23) Tray sorter

A high speed type of sorting conveyor with sorts in the 250 cases per minute range, this type consists of a continuously moving train of independent trays that move in a straight line and recirculate in either a horizontal or vertical (over and under) closed loop. At the proper moment, controls cause the tray to tilt to either side, thereby discharging the load to the desired take away lane.

24) Overhead conveyor

A form of conveyor consisting of a continuous chain running beneath a continuous, stationary, flanged rail. Individual carriers spaced equidistant along the length of the conveyor are suspended from the chain. The chain pulls the carriers. Vertical support is derived from the fact that the carriers are also connected to a small trolley with wheels that roll cross sections, trolleys and carriers. A few common carriers include a tray, platform or simple hook. A less common alternative to the chain drive is a worm drive.

25) Vertical reciprocating conveyor

A conveyor that moves perpendicular to the floor and provides intermittent operation of a single load-carrying platform or cage which travels up and down on steel rails or guideways. There are many configurations of vertical reciprocating conveyors (VRCs) including those with a single mast, single rail, double mast, double rail and even models which offer incline travel versus strict vertical travel. There are also numerous platform configurations ranging from a simple flat steel surface to a powered roller conveyor deck with controls that are integrated with the controls of powered feed and take away conveyor lines at the different levels.

26) Poternoster

A type of vertical conveyor that provides for continuous operation of multiple, equally spaced, load-carrying units fixed to chains that move continuously in an endless loop. With such a system the loading and unloading, usually automatic, occurs while the conveyor is running, resulting in greater throughput and an even flow of loads. This type of vertical conveyor is common in Europe

27) Platform conveyor

Another form of the conventional poternoster (See definition for Poternoster) is the platform conveyor that consists of multiple, equally spaced battens which form rigid horizontal surfaces in one direction (up and down) but behave like the front of a roll top desk on the return. Platform conveyor is an effective means of moving a continuous flow of pallets or other unit loads between levels. Another variation of the posternoster concept, which permits both vertical and horizontal movement of load, consists of freely swinging platforms suspended between two parallel chains.

28) Manipulator

A stationary (does not mean that nothing moves) movement assist device that is often equipped with end effectors for handling different types of loads. End effectors include all forms of grippers, forks, barrel grabs, etc. Manipulators counteract the weight of the load, rendering it almost weightless by way of hydraulic or pneumatic cylinders, or simply by way of counter weights and the exercising of very limited manual control. Most manipulators require manual actuation and control and are therefore manual assist devices. They are mounted to the floor, wall or ceiling. In some cases, manipulators are mounted to a fixed base plate and the entire unit can be moved via a trolley, cart or frok lift truck.

29) Nets

A basic form of below-the-hook lifting attachment which is suspended from a hoist or other lifting mechanism and simply wraps around the object to be moved and lifts it totally. Mesh netting is also used for securing loads to pallets.

30) Euro-pallet

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.
