The brake lining used in a DEMAG 1‑ton overhead crane with a conical brake system is engineered to maintain a stable friction coefficient between 0.36 and 0.44 under normal operating conditions. The initial lining thickness is typically 5 to 7 millimeters to ensure uniform wear and long service life. The effective contact diameter of the lining is generally selected between 90 and 120 millimeters to provide a braking torque of approximately 100 to 150 newton meters. The lining material is usually a combination of heat‑resistant epoxy resin and industrial fibers capable of withstanding temperatures up to 220 degrees Celsius, ensuring high thermal stability during repeated stop-and-lift cycles.
In the design of this lining for the DEMAG 1‑ton hoist, industrial standards require the lining to dissipate 300 to 450 watts of thermal energy per braking event to prevent performance drop during frequent operation. Uniform contact with the conical brake disc reduces localized wear and prevents sudden increases in the brake air gap. This engineering design ensures consistent braking torque, high durability, and safe load handling during continuous lifting and frequent start-stop cycles.
