Galvi GALVI Shoe Brake type NV.HYD

The GALVI Shoe Brake type NV.HYD is a safety component which, installed on a rotating Brakedrum, decelerates and stops the Brakedrum through pressure and friction, that is to say through a closing spring, a system of levers, a friction material and an electrohydraulic Thruster whose function is to open the Brake with a lifting Force in contrast with the Force of the Brake’s main spring.

The Brake is normally installed between motor and gear box, that is to say on high speed shaft, with Brakedrum always installed on gear box side, which is the load side, so that it can brake a lifted mass or a travelling or a rotating mass.

The Brake is combined with the GALVI flexible Coupling with Brakedrum type GD or GL or, in case the Brake is not installed between motor and gear box, with the Brakedrum type PD or PL.

The main dimensional features of the Brake are in conformity with the DIN 15435 Standard, the ones of the Brakedrum are in conformity with DIN 15431 Standard.

The range of Brakes and Brakedrums is available with diameters 160, 200, 250, 315, 400, 500, 630, 710 mm.
