The Friction Plate for Construction Hoist Motor is a critical safety component engineered for heavy-duty braking systems in construction hoists, elevators, and mining equipment. Constructed from premium sintered iron or sintered bronze materials, these plates deliver consistent high friction coefficients (0.15–0.30 dry) and withstand extreme temperatures up to 300°C—ensuring reliable stopping power even under heavy loads .

Designed with precision-grooved surfaces, the plates optimize oil flow during braking, preventing heat buildup and reducing wear. Their modular design allows for quick replacement, minimizing downtime in critical applications where equipment availability directly impacts project timelines. Whether in tower cranes, material lifts, or emergency braking systems, these friction plates set the standard for durability and performance in high-stress environments .
Sintered iron: Composed of iron powder with graphite and copper additives, this material offers exceptional wear resistance and high friction stability, making it ideal for heavy-load applications like tower cranes and mining hoists.
Sintered bronze: A copper-tin alloy with self-lubricating properties, providing superior corrosion resistance in marine environments, coastal construction sites, or chemical plants .
Grooved patterns: Laser-etched grooves (1–2 mm depth) enhance oil circulation, preventing glazing and reducing brake fade during prolonged use.
Precision machining: Tolerances of ±0.05 mm ensure uniform contact with mating surfaces, guaranteeing consistent braking torque across the plate’s entire surface area .
All friction plates meet ISO 15110 standards for construction machinery safety and are CE-certified, ensuring compliance with European safety regulations. They undergo rigorous testing, including friction coefficient verification, thermal stability checks, and wear resistance trials, before leaving the factory .
Construction Hoists: Braking systems in tower cranes, passenger lifts, and material hoists on construction sites.
Elevators: Emergency braking mechanisms in high-rise building elevator systems.
Mining Equipment: Winch brakes and conveyor stopping systems in underground and surface mining operations.
