1) Structural lifter

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

2) Supporting lifter

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

3) 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.

4) Scissors lift

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

5) Tong grab

A lifting attachment usually used in conjunction with a hoist or forklift that utilizes a "scissors" action to grip a load for vertical lifting or transport.

6) Telescoping lift truck forks (hydraulic forks)

Hydraulic lift truck forks that can be used for one sided loading, double-deep stacking and as hydraulic fork extensions.

7) Shelving post system

The vertical upright member that supports the horizontal shelf.  Posts are manufactured in a variety of configurations.

8) Truss girder crane

An overhead traveling crane designed with structurally reinforced bridge girders to allow greater span and loading capabilities.  The reinforcement consists of utilization of trusses extended vertically and horizontally from the load bearing beam(s) of the crane bridge.

9) Strap hoist

A lever operated manual device, utilizing polyester or nylon straps as the lifting medium, used to lift, lower, or pull a load and to apply or release tension.

10) Straddle truck

An industrial lift truck that is utilized in aisles as narrow as 6 feet and has had the counterbalancing addressed by front end outriggers. These outriggers also serve to prevent the natural forward tipping motion that would be created as a load is lifted

11) 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.

12) 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.

13) 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.

14) Slip sheet

Often a piece of cardboard or plastic sheeting on which a load is placed and is moved/removed with a special fork lift equipped like forks with rollers and/or push pull attachment.

15) Single girder crane

An overhead traveling crane that utilizes a single bridge beam attached to the two runway/end trucks.  This bridge beam or single girder supports a lifting mechanism or hoist that "runs" on the bottom flange of the bridge beam.
