How Many Breakdowns Are Acceptable?

The number of acceptable breakdowns that a lift may experience is an emotive subject. There appears to be only one published record that says that four breakdowns per annum are acceptable before an interest should be taken into the reasons why 1. The owner of the lift may also have a different view of the acceptable number of breakdowns compared to the contractor. There are also a number of variables that have an input into the number of breakdowns that actually occur – age of equipment, external influences (power cuts etc.), type of equipment compared to environment, type of occupant, skills level of maintenance operative, type of maintenance contract, whether maintenance is even being undertaken, and also the number of landing doors being a few. The question is…. can an acceptable number of breakdowns be agreed upon subject to the equipment being the right type for the right environment?
