When you buy a lift through a reputable lift company, they will provide 24/7 cover for any breakdowns or necessary repairs. Before installation, they will perform a risk assessment at your location to ensure that they are aware of any risks regarding the fitting of your lift. All work carried out will be done by fully-trained, experienced and knowledgeable staff. This will reduce the risk that your lift will require any repair or maintenance.
However, with large pieces of machinery such as lifts, there is always the chance that things can break, become damaged or require servicing, so a qualified technician will be on hand to take your call if you do run into an issue. If you have a professional lift company that offers 24/7 emergency repairs, they will have the knowledge and a wide-ranging catalogue of spare parts to fix your emergency in no time at all.
