THRUSTER DRUM BRAKES – SAB AISA

SPECIFICATIONS

TSB braking force is applied to the brake shoes by a pre-stressed coil spring. The oversized brake shoes with friction material press on both sides of a rotating steel drum, providing the friction forces and thus braking capacity. Brake shoes are released from the disc by an electro-hydraulic thruster.

BENEFITS

Designed as service brakes to be applied on high speed shafts of modern drives, winches and hoists in order to slow or stop its rotational movement. Thruster disc brakes possess a scalable torque tube which means that torque can be adjusted to the exact torque amount which yields more precise braking and enhanced safety.

Wheel brakes are used as a supplement to the motor gantry brakes and are mounted on the idler wheels of a container crane. By applying a friction force on the wheel flange, they minimize the amount of strain and stress otherwise placed on sill beams and truck assemblies of the crane. A minimum braking torque is applied to hold the crane against the wind burst in conjunction with the existing gantry motor brakes.
