Thruster Brake is a mechanical device which is used to obstruct the speed of any moving machinery which stops the machine accurately to the desired position. This braking force is applied by a shoe-shaped brake through a compressed spring, which the brake employs an electromechanical thrust to the device. Boson Engineers in India, manufactures such brakes since 2002 which this article focuses on its usages.
How Does It Works?
By pressing the shoe of the brake on the rotating body, an electromechanical thrust employs a braking force where it allows the speed of the machine to stop, which is done by releasing the tension of the spring. The force, hydraulic force, is fixed irrespective of load leading to improvement of load positioning.
Assembly And Function
The assembled part of the brake shoe has a pair of cast iron shoes lined up with friction pads where each of them has a pin fitted in the side arm. These are connected by a rod, the top is hinged in the main arm and locked to the side arm by a lock nut. A crank lever is attached to the main arm and the other end is fixed on the clevis top of the thruster by a pin. The braking of the high torque depends on the pre-tension of the spring. When this thruster is not energized, the shoe brake pressed on the brake drum which is fitted in the system and it holds the effect of braking force provided by the spring, not allowing the drum to rotate.
Applications
The thruster brake has a wide range of industrial application due to its positive characteristics such as brake activation, coupling drive, valve drive, gate valve drive, shearing machine etc. It is also used in the following applications such for crane, hoists, steel rolling mills, cement equipments, heavy engineering equipments, surface mining machine such as excavators, stackers and many other combination services.
Since it can operate at vertical and horizontal position, this thruster has very useful applications and are fully reliable for any kind of machinery work to be done.
