= Introduction =

A lift table is a platform deck that is elevated to raise or lower loads, including people, through relatively small distances. There are many different configurations of lift table that can be adapted to various specialised tasks and purposes. Common applications include handling pallets, loading vehicles, and positioning work so that it is more easily accessible.

In terms of regulation, the British Standard EN 1570: 1998 + A2: 2009 Safety requirements for lifting tables, is applicable.

The factors to consider when deciding on the most appropriate lift table include the following:

* Maximum weight capacity.
* Physical dimensions of the table.
* Elevation capability, from contraction to full expansion.
* Power source and mechanism providing the table’s lift.

= Types of power source =

It is usual for power to only be supplied during elevation. Lowering the table is achieved by using a purge valve or slow-release mechanism.

There are various different means of providing power to the lift table:

* Manual: Operator-controlled crank, pump, racket or screw.
* Pneumatic: Pressurised air cylinder in conjunction with a compression mechanism.
* Hydraulic: Pressurised hydraulic fluids power a linear actuator.
* Electric: Rotational power source provided by an electric motor.

= Types of lifting mechanism =

There are various different mechanisms which can control the lifting of the table, including the following:

* Scissor: Power source collapses the base of a pantograph to extend table supports.
* Screw: Table is translated along the length of a screw as it rotates.
* Rack and pinion: Rack rotation moves the table along the track provided by the pinion.
* Telescoping: In the hollow cavity of a larger cylinder are stored linear actuators.
* Articulated: Jointed arms extend by the use of linear actuators, offering some horizontal movement as well as vertical.
* Chain and sprocket: Rotating sprocket with a chain drive oriented vertically.

= Safety features =

Some lift tables include safety features which aim to prevent injury to the operator. These can include the following:

* Release lock: The table locks in the event of a malfunction while extended.
* Pinch guard: If objects are compromising the table’s ability to compress, an underlying pressure-sensitive device stops the descent.
* Bellows: To prevent items compromising the lifting mechanism a skirt of rubber or vinyl can surround the lift table.
