The DFXY braking system is fitted to, gearless (G200, G300, G400) as service and safety brake and to gearboxes(MODY, LEO, MF48, TORO) as standard safety brake against uncontrolled upward movement of the cabin (certification TUV n ° EDPS 017/1)
The DFXY system is designed, developed and manufactured entirely by Alberto Sassi technicians to obtain the best performance synergies with the models on which it is applied.
Modular brake: mechanical elements (braking disk, disk pusher, thrust springs..) and electric (coil body, micro-contacts...) that are combined together to obtain the various braking torque required.
3 sizes available:
- DFX1: module with 1 braking disk
- DFX2: module with 2 brake discs
- DFX3: module with 3 brake discs
Dimensions are reduced to minimum: we decided to increase in length and to keep the width at 280mm which is the optimal dimension for MRL systems.
The opening of the brake, during operation, is ensured by 4 coils connected in series and in pair. However, the electrical output connection to the terminal block is made in parallel to ensure shutdown even in the presence of only half working brake (test required for various approvals).
The nominal continuous supply voltages (DC) of the DFX system are:
205V - 180V -104V - 60V - 48V
To improve the precision and strength of the rotating parts, it was decided to couple the system directly to the machine shaft with the aid of grooved profiles, thus avoiding the interposition of adapter bushes.
The DFXY braking system normally operates with an electromagnetic release which, however, in case of emergency, can be changed to manual through the opening of special nuts (standard equipment).
It is possible, on request, to install a manual release lever whose simple installation can be done before, during or after the machine is mounted to the installation.
