The DGXY braking system is a service and safety brake, certified as a safety brake against uncontrolled movements (UCM) and upward overspeed of the cabin (ACOP) (Liftinstituut certification (Netherlands) n. NL20-400-1002-243 -02) according to the European Directive 2014/33 / EU.
The DGXY system was designed, developed and manufactured totally by Alberto Sassi technicians following the experience gained in the design of safety brakes in the lift industry with the aim of maximizing the braking torque on truly compact dimensions.
The DGXY brake is modular, a patented feature common to the other Sassi safety brakes: mechanical elements (braking disc, thrust disc thrust springs) and electrical (coil body, micro contacts) elements that are common and are combined with each other to obtain the various braking torques required for the same electrical power consumption.
The main sizes are three:
- DG01: module with 1 brake disc
- DG02: module with 2 braking discs
- DG03: module with 3 braking discs
and there is also a version for Home Lift
- DGA1: module with 1 braking disc and braking torque adapted to the lower inertias present
The brake opening, during the movement of the system, is ensured by 4 coils connected in series 2 by 2.
The electrical output connection to the terminal block is in parallel in order to be able to carry out, as required by law, the full load braking test with only half brake operating.
The nominal direct voltage (DC) of the DGXY system are:
205V - 180V -104V - 60V - 48V
To improve the precision, strength and silence of the rotating parts, the system is coupled directly to the machine shaft by means of DIN standard grooved profiles thus avoiding the interposition of adapter bushings.
The DGXY braking system operates normally with electromagnetic release.
In the event of an emergency, the opening can be done manually by means of special release screws (standard equipment).
The particularly compact design of the DGXY system also allows the possibility, upon request, to mount two independent manual release levers, the simple installation of which can also be carried out after the machine has been mounted on the system.
