DQ Brakes

The DQ02 brake system equips the models:
Gearless G-400 T2 as a service and safety brake (starting from 06/05/2024)

The DQ03 brake system equips the models:

Gearless G-400 T3 as a service and safety brake (starting from 1/03/2020)
Gearbox TORO as safety brake

DQXY brakes are certified as safety brakes against uncontrolled movements (UCM) and overspeed in cabin ascent (ACOP) by Liftinstituut (Netherlands) according to European Directive 2014/33/EU.

Certificate No. NL17-400-1002-243-01

The DQXY system was designed, developed and manufactured entirely by Alberto Sassi engineers to reduce dimensions and optimize braking torques.

Modular brake, available in three sizes:

DQ01: module with 1 brake disc

DQ02: module with 2 brake discs

DQ03: module with 3 brake discs

Brake opening, while the system is operating, is ensured by 4 coils connected to each other in series, 2 by 2. However, the electrical connection at the terminal box output is in parallel to ensure the elevator stops even if only half the brake functions (test required for several type-approvals).

The standard rated direct voltage (DC) values required to supply the DQ system are:

205V – 180V -104V – 60V – 48V. (Other voltages on request)

The DQXY braking system normally functions with an electromagnetic release which, however, can become manual in an emergency by unscrewing purpose-made release bolts (standard equipment).

On request, the system can be fitted with a manual release lever, which can be installed before, during or after the machine has been fitted on the system.
