Serie LIFT
Characteristics of model “LIFT”
The electromechanical model LIFT is a spring pressurised brake, fed by direct current. The model LIFT acts in conformity with the normative law 95/16/CE for goods-lifts and lifts. The aim of the brake is that of guaranteeing the static positioning of the drive shaft during the opening and closing phases of the doors. For this reason graphics relative to the consumption haven’t been reported. The building typology of the brake foresees a central magnetic system, kept in position by brake adjusters. A couple of armature plates operate separately on the braking disks, determining a double safeness on the system.
The braking torque value considered by the normative law is that developed by one brake alone. The brake is arranged to hold a two micron switch for the checking of the opening and closing of the armature plate. The main characteristics of the LIFT brake are:
• Variable braking torque, established in the building phase of the brake.
• Strong structure.
• Maximum silence in interventions, in opening as in closing <50 dBA.
• Maximum silence in rotation. The precise matching of the hub and the disk, and the insertion of the centering gasket, avoid that noise is made during the rotation of the group. The constructive structure of the brake with the two armature plates and the fixed central part, guarantees the releasing of the disks during their rotation.
• Good dissipation of heat. The brake is projected for a use without ventilation.
The bearing is supplied with a flange connected to the bearing of the motorising system, due to the weight and torques developed. These do not permit to apply it directly connected to the bearing structure of the motor. The brake is provided with a patented system of blocking. This system guarantees the total release of the two disks. It may be activated by cables or levers with commands which are tangent or perpendicular to the rotation axis. The spool of the electromagnet is completely cemented with epoxy resin, unless of other construction criteria, and its mechanical parts are protected by a zinc plating chemical treatment.
