New brake safety gear

At interlift 2019, the Spanish company Dynatech along with its German partner Vertima, presented its first electromechanical brake safety gear. At interlift 2023, Vertima presented the new Dynatech electronic safety gear.

Since the launch of the electromechanical brake safety gear, Dynatech has never lost sight of the further development of this technology. The aim was to make its safety gear more compact and even more efficient.

This development process has now been completed. The new electromagnetic brake safety gear eASG EVO (single-acting) and eASG UD EVO (double-acting) are already in the final phase of the approval procedure.

The basis of this safety gear remains the existing mechanical main component, the ASG safety gear, which has been established on the market since 2007. The results of the further development are smaller component dimensions and increased efficiency, among other things in the interests of reduced installation effort.

Also to protect the fitters

The deployment range of the new electromagnetic safety gear e-ASG EVO is a maximum permissible total mass P+Q of 4233 kg (in double arrangement 8466 kg) and a tripping speed of up to 3.90 m/s.

In combination with a suitable SIL3-certified safety system, the eASG EVO safety gear can not only be used due to its design with reset and holding magnets as a safety system for passengers but also to protect the installation personnel when realising protective rooms and/or in the event of installation without scaffold.

Moreover, this innovative technology makes it possible to dispense with many components used in conventional lifts. (see illustration). This then results in a reduction in installation and maintenance costs and as a result reduces the timespan needed for correcting errors in the event of malfunctions.

Fits in almost every supporting frame

The new safety gear is designed to fit into almost every supporting frame – whether a centrally guided safety frame or backpack frame. Due to the design of the e-ASG EVO, mechanical connection of the two safety units with each other can be dispensed with. As a result, the safety gear, without connection shaft, is capable of space-saving installation on the side of the frame and no additional space is needed above or below the supporting frame.

Particularly when used in lifts with reduced shaft pit or shaft head, such a solution permits exploiting additional millimetres for further reduction of the shaft pit or -head.

To facilitate seamless integration in conversion, retrofitting and modernisation as well, the e-ASG EVO can also be delivered with a suitable attachment console and matching "electronic speed governor". Vertima unveiled these new types of brake safety gear at interlift 2023 to the public.
