Rotary Geared Limit Switch

Electro Hydraulic Thruster Brakes

Introduction :
Thruster brake is a device to retard the speed of moving machinery and to stop it accurately to the desired position. The braking force is applied to the brake shoe by a pre-stressed compression spring. The shoes press on the rotating brake drum retarding its speed and finally stopping it. The releasing of the brake and compressing of the spring is done by the Thruster. The thruster shoe brake has a pair of cast iron shoes which are lined up with friction pads. The shoes are hinged on the main arm and the side arm of the brake, each of them having a hinge pin fitted in the base. They are connected to each other on top by a tie rod, which is hinge in the main arm and locked to the swivel block in the side arm, by a lock nut. When the thruster motor is energized, the thrust provided by the thruster lifts up the crank lever which moves the arms and the shoe brakes away from the brake drum, and releasing the braking force. The spring is compressed and braking energy is stored for the next cycle.

Features :
• This is a spring loaded normally ON Failsafe Brake
• Consists of Electro Hydraulic Thruster, Torque Spring and Liner riveted to Brake Shoes
• Works on 415 V AC, 3 Phase, 50 Hz supply.
• Requires Transformer Oil to be filled in the thrust- er cylinder.
• Function is to bring to stop, moving / rotating machinery like motor / gearbox.
• Holds / stops the load in desired place. Instant stop.
• Prevents jerk due to soft stop.
• Maintenance free, robust design.
Range :
• Drum diameter 100mm to 600mm
• Thruster Capacity (Kg) : 18, 34, 46, 68, 114
• Torque Capacity : 6 Kgm to 580 Kgm
Applications :
• All Material Handling and Lifting Equipments
• Hoisting : electric wire rope Hoists and Crabs
• Cross travel and Long travel : EOT / Gantry / Goliath / Derrick Cranes
• Winches and Conveyors
• Lifts and Elevators
