Brake Disc

250kg demag hoist conical brake disc

The brake lining used in a Demag 250 kilogram hoist is a critical component that generates the required braking torque and maintains load holding performance under dynamic conditions. This lining typically works with a conical or flat brake disc and supplies a controlled friction coefficient to manage braking energy. Its engineered surface distributes pressure evenly across the disc and prevents localized wear. For a 250 kilogram hoist, the braking torque usually falls within several tens of newton meters, which requires a lining capable of stable thermal dissipation. The material generally combines industrial resin with heat resistant fibers to maintain consistent friction during repetitive cycles.

This lining is produced according to safety standards defined in DIN and EN regulations, ensuring reliable stopping capability even in unbalanced load scenarios. The lining thickness is typically a few millimeters, and the maximum allowable wear is specified by the manufacturer to maintain torque accuracy. A correct lining for a 250 kilogram capacity must support frequent start stop duty with minimal fade. Using an original high density lining preserves nominal braking torque, reduces vibration, and prevents excessive air gap growth. Selecting a lining with uniform compression stre
