What is the detailed impact of adapting to the new norms? The goal is even better protection for passengers and maintenance personnel. As well as flame-retardant cars and improved protection against pinching by lift doors, larger refuge spaces for maintenance personnel have to be created in the shaft pit and on the cabin roof. Here, Hengstler can use the H-480 safety relay to its full advantage, to give maximum support to lift manufacturers as they adapt to the future safety guidelines.
In future, even more people will ride in faster and faster lifts. To ensure that passengers and maintenance personnel are transported safely depends on high quality and reliable components. For safe opening and closing of lift doors, they must only be enabled when the car is stopped. At the same time, fast entry and exit is becoming more and more important. This trend is referred to as comfort control. It allows the lift doors to open a few centimetres before the final stop position, to enable faster passenger changeover. This dynamic and yet safe type of control is naturally supported by Hengstler safety relays.
For maintenance personnel to inspect the lift shaft when performing maintenance, they must be able to operate the lift with the cabin door open. For this purpose, it has to be possible to disable the safety systems. During normal operation, this safety loophole is blocked by a safety relay, but when operating the lift with doors open, maintenance personnel can still stop the lift at any time by pressing the emergency stop button.
Riding in a lift has never been faster, more efficient or more comfortable. And in future, new records in terms of speed and traffic numbers will be set. Safety relays have a special role to play in safely transporting passengers and maintenance personnel. With H-480, Hengstler's newest family of relays, lift manufacturers can avail of the latest components, capable of handling all today’s and future requirements.
