The brake lining for the 2-ton Demag electric crane is made from asbestos-free friction material, combining phenolic resin and metallic fibers to ensure thermal resistance up to 300 °C and stable friction under heavy load. The initial thickness of the lining is typically between 10 and 12 mm, and the contact surface with the brake disc is designed to distribute pressure evenly, minimizing wear. The length and width of the lining are matched to the disc diameter and mounting spacing, with installation secured using vibration-resistant bolts tightened to a torque of 150 Nm.
The friction grade of the brake lining is calibrated between μ = 0.35 and 0.45 for optimal stopping performance in 2-ton hoists, ensuring precise load control without slippage. The lining design incorporates ventilation channels and longitudinal grooves to reduce operating temperature and extend service life beyond 10 years. The material composition and surface coating provide high resistance to moisture, dust, and corrosion, allowing repeated load cycles in demanding industrial environments.
