How often should a lift's safety gear be tested?

The safety gear, overspeed governor, and buffers must be tested at least once a year (Annex A).

What load is used for the annual brake test?

The braking system is tested with the car carrying 125% of its rated load (Clause 5.3.2).

Who is qualified to perform these periodic tests?

The tests must be performed by a 'competent person' or an authorized body as recognized by the relevant statutory authority.

What does a routine monthly lift check involve?

Monthly checks typically include testing of levelling accuracy, door operation, safety edges, light curtains, and the alarm/intercom system (Table A.1).

This standard specifies the procedures for type examination tests for lift safety components such as safety gears, buffers, locking devices, and overspeed governors. It ensures these critical components meet stringent safety and performance requirements before they are approved for use. This standard is the Indian adoption of the harmonized European standard EN 81-50:2020.

Specifies procedures for type examination tests of lift components and safety devices.

Practical Notes

This standard is harmonized with the European standard EN 81-80, focusing on improving the safety of existing lifts.

Maintaining a detailed logbook for the lift is mandatory as per this standard and is the primary document reviewed during any inspection.

The frequency of tests in Annex A (e.g., weekly, monthly, annual) is the minimum requirement; local statutory bodies (like the State Lift Inspectorate) may require more frequent or additional tests.
