Description
Direct Acting Spring Disc Brakes
Direct Acting Spring-Applied Disc Brakes can be used for multiple applications including hoist and conveyor systems,
making them ideal for various industries such as Mining (conveyors, ball and sag mills), Oil (service and emergency
brakes for drawworks), Steel (emergency brakes for main hoist), Container Cranes/Bulk Handling (Emergency Caliper Disc Brakes), and others.

Direct Acting Brake Caliper Selection The brake size must be chosen to give required braking torque and to dissipate the energy during stopping without over heating the disc. Brake torque is often related to drive motor torque by an arbitrary service factor typically 75% -100% full load torque for crane travel and similar inertial loads which tend to be self stopping or 150% -200% for crane hoists and other overhauling loads. If a precise stop time or distance is specified, then the brake torque must be calculated.Motor Full Load Torque is given by: MFLT = [(kW x 9550) / rpm]Nm or [(HP x 5250) / rpm]LbftCalculate stopping torque based on the diameter of your disc, use the following table and equations:Imperial Torque Dynamic Torque = AF x 0.50 x (D – F) / 24 Static Torque = AF x 0.40 x (D – F) / 24Metric Torque Dynamic Torque = AF x 0.50 x (D – F) / 2000 Static Torque = AF x 0.40 x (D – F) / 2000 AF = Applied Force |
