Are excavators suitable for use for lifting operations?
In most instances excavators will not be the most suitable equipment, as they are primarily designed for earthmoving.
The Provision and Use of Work Equipment Regulations 1998 (PUWER) requires work equipment to be constructed or adapted to be suitable for its purpose, and a suitable and sufficient assessment of the risks must inform the selection process.
Do all excavators require thorough examinations as required by Lifting Operations and Lifting Equipment Regulations (LOLER)?
No. Only excavators that are used for lifting operations are subject to thorough examination. If the machine is used for lifting then it must be thoroughly examined and additional safety devices must be fitted, such as check valves and an audible warning device.
What if I only use it to lift occasionally?
If you plan to use an excavator for lifting, then you must have it thoroughly examined by a competent person as this is a control measure for the additional risks involved in lifting operations.
If the only job they do is conventional 'earth moving' then the requirements of the PUWER apply, and there must be an appropriate maintenance regime, including inspection of the machine at intervals specified by a competent person.
