After installation GTI will test passenger/goods hoists every 6 months and goods only/beam hoists every 12 months, as specified by LOLER regulations. GTI qualified examiners also carry out inspections after significant damage, modification or partial dismantlement. Load tests are carried out, including with visual inspections including the integrity of all connections, by a trained GTI engineer. The load testing involves driving the hoist through the full length of the mast and checking the integrity of the structure by loading the hoist with a higher percentage of its safe working load. The percentage load will be determined by the specific hoist manufacturer.
