It is important to examine elevator every six months if it is used to carry people or animals and every 12 months if it carries nothing except loads, such as industrial materials or other inanimate objects. If there have been any significant changes in the structure or use of the elevator, it should be inspected by a professional. Other circumstances require an inspections, such as after major repair, or if there has been damage to, or failure of the lift in any way. There has to be an examination if a lift has just been installed in a building or industrial area, or if a pre-existing lift has been replaced with a new one. All of these examinations and repairs must be documented, with the serial numbers of the parts noted, the date when the maintenance was undertaken, the reason behind the examination or maintenance, and detail all actions performed. These records should be retained for record-keeping purposes.
Elevators are complex machines, so there are several parts that need to be regularly maintained to keep it up to code. All the gearing should be checked for wear and tear, as well as all the doors.
