1) Lift

The maximum vertical distance through which the load hook can travel.  The total allowable hook movement between its upper limit of travel and its lower limit of travel. The term "Lift" or "Lifts" may also refer to lift tables, scissor lifts and personnel lifts. Lift tables are ergonomic devices utilized to raise, lower or tilt work loads such as pallets and containers. Lift tables are a scissors lift device used to raise, lower, stack, convey and/or transfer material between two or more elevations and not limited to landings. Such movement enables the worker to access the load at an acceptable level so as to not exert undue physical strain while working with the item(s). A scissors lift is a raising/lowering device that is supported or stabilized by one or more pantograph leg sections. Likewise, personnel lifts are used to raise and lower humans to appropriate working heights so that they may work at a safe reaching level and will have benefit of increased movement not afforded by a conventional ladder.

2) Lift cart

A hand cart with a scissor or mast supported lifting platform.

3) Lifting capacity

The rated load of a material handling lifting device (i.e., scissors lift, hoist) applied as uniformly distributed load.

4) Lift tables

A scissors lift device used to raise, lower, stack, convey and/or transfer material between two or more elevations and not limited to landing.

5) 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.

6) Lift Manufacturers (LMPS) Industry Group

The Lift Manufacturers Product Section (LMPS) members are the resource for industry best practices, standards, information, and equipment that lifts, rotates, tilts, and otherwise positions materials. Industry scissors lifts and tilters can also improve the working interface between people and the materials they must move to reduce injury, increase productivity, and eliminate wasted motion, while providing a significant return on investment.

7) Jib crane

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).

8) Link chain

A form of chain made up of a series of metal loops or links that are joined together pivotally and form a medium for lifting or conveying and transmitting power or motion.

9) Lever hoist

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.
