Lift safety is at the forefront of every new design process. Companies are always looking for new and innovative ways to make lift systems more efficient and safer than ever before. As well as developing cutting edge technology and finding ways of maintaining lifts that is quicker and more efficient than before, lift companies must also ensure that all their systems are fitted with standard safety equipment that is required by law.
Some safety equipment comes as standard in all elevators due to their history of reliability. If you have a lift installed that doesn’t come equipped with the following safety measures, then your system will not pass inspection, and will therefore be unlawful to operate:
- Door Locking Device
All modern lift cars are equipped with outer (landing) doors as well as inner (car) doors. Both sets of doors are equipped with mechanical door locks to securely hold the landing doors and the car doors in a locked position, preventing them from being opened when the car is in transit, or isn’t aligned accurately with a landing space.
- Overspeed Governor
All lifts are set to operate at certain speeds; if the lift car exceeds these pre-determined speeds then the overspeed governor will activate the safety device, bringing the lift car to a stop.
If there is a case of malfunctioning within the elevator shaft and the lift car does fall, then the last line of defence is the buffer system. The buffer acts as an additional safety protection. Their main function is to reduce any impact of the lift car, minimising any injuries that may occur from the sudden collision if the safety gear should fail.
- Safety Gear
If the overspeed governor detects the lift to be moving at a speed higher than the pre-determined limit, then the safety gear is activated. The safety gear grips the guide rails and brings the lift to a stop if the suspension devices break.
Regular lift maintenance is essential in ensuring that these systems are in full working order, so that in the event of any fault, no accident should occur.
