Thrustor Brakes By Suni Cranes Controls

The a Suni Cranes Controlsa Thrustor Brakes is electro hydraulic device to apply pressure or actuate lever

mechanism of brake arrangement.

An Electro-hydraulic thrustor is an independent mechanism which requires neither clutches nor external piping. The thrustor cylinder accommodates a centrifugal pump and a piston with two push-rods extending outside through thrustor cover and transmitting effort to the brake
The robust design Thrustor unit is compact and has long life and is easy to maintain.
Main components used are of high quality cast iron and steel.
The Thrustor is operated by an integral three phase squirrel cage motor.

The device has the following advantages:
1. Constant Pressure
2. Gentle Application and release of brake without jerks and shocks.
3. Larger number of switching-in operations per hour (up to 720).

The rated stroke of each type of thrustor can be changed, retaining the same attractive force, by means of sleeves fitted on the rods (inside the body) (this arrangement is possible with models from ST 535 and above)
In cranes / hoisting machinery, brakes are intended for controlling the speed of load, lowering or for holding the suspended load at rest

Suni Cranes Controls Mill duty Thrustor Brakes are suitable for 400/440 Volts, 3 Phase A.C. supply for a wide range of drum sizes, from 100mm to 600 mm dia. Higher sizes can also be supplied against specific requirements.
