1.A6.3 DEFINITIONS

Definitions are as stated in section 1.3 DEFINITIONS of this code but with the addition of the following:

1.A6.3.1 Jacking

Jacking is the act of raising a load with an appliance (known as a jack or ram) which is placed under the load and which effectively pushes the load upward or lowers the load whilst supporting it from beneath.

1.A6.3.2 Lifting

Lifting is the act of raising and/or lowering a load with an appliance and other lifting equipment which is placed above the load and which effectively picks the load up or lowers it whilst supporting it from above.

1.A6.3.3 Lifting Appliance

A lifting appliance is defined in section 1.3.6 Lifting Equipment as any machine which is able to raise, lower or suspend a load but excluding machines incorporating a guided load (e.g. lifts) and continuous mechanical handling devices (e.g. conveyors). However, in discussing the general selection of lifting appliances, it is necessary to differentiate between the component parts and therefore to extend this definition. For the purpose of this appendix therefore, lifting appliance is considered to be a generic term and may be a lifting mechanism, trolley or a structure which is fitted with a lifting mechanism.

1.A6.3.4 Lifting Application

A lifting application is any application where, a load is suspended or supported on inclined planes where removal of the lifting force or any failure of the lifting mechanism or lifting medium results in either movement of the load, or a movement that can present a significant hazard.

1.A6.3.6 Pulling Application

A pulling application is any application where, a load supported on level or inclined planes where the removal of the pulling force or a failure of the pulling mechanism or pulling medium results either in no movement of the load, or a movement that cannot result in a significant hazard.

1.A6.3.7 Structure

A structure is that part of a lifting appliance which supports the lifting mechanism. It may be static providing a track upon which the lifting mechanism is able to travel or it may have means that enable it to be moved, as in the bridge of a bridge and gantry crane or the boom of a tower crane.
