The required frequency of lift servicing in the UK may vary depending on the type of elevator and its usage. In order to be able to enhance the availability of a lift, it is important to review regularly the most critical security components and the ones subjected to constant wear. Therefore, a maintenance program should be tailor made to meet each lifts specific requirements. It is also important to note that lifts must undergo a thorough examination by a competent person, as required by the Lifting Operations and Lifting Equipment Regulations (LOLER). The LOLER regulations 1998 require a thorough examination “in the case of lifting equipment for lifting persons or an accessory for lifting” at least every 6 months by a competent person.
