Product description

Groxx Traction Hoist Components | GRXFD800 High-Torque Friction Disc
The Groxx GRXFD800 is a heavy-duty, high-coefficient friction disc engineered for 800 kg capacity traction hoists. Installed within the internal brake and clutch assembly, the GRXFD800 provides the essential frictional force needed to hold, arrest, and control heavy loads during vertical transport. It is a critical wear component for maintaining immediate stopping capability, preventing load slippage, and ensuring operational safety on suspended access platforms and swing stages.
Primary Functions
  • Dynamic Motion Control: Generates instant, predictable stopping torque when the electromagnetic brake engages or the motor power is cut.
  • Static Load Retention: Holds suspended platforms securely in place at rest, preventing unexpected drift or sliding under static 800 kg loads.
  • Controlled Energy Dissipation: Converts kinetic energy into thermal energy during deceleration, providing smooth, controlled stopping without violent jerks or mechanical shocks.
  • Overload Protection: Acts as a mechanical slip interface in secondary clutch mechanisms to safeguard internal gears and shafts against sudden impact loads.

Key Technical Features
  • Non-Asbestos Composite Compound: Formulated from advanced aramid fibers and metal-particle composites to deliver stable friction coefficients across extreme operating temperature ranges.
  • Thermal Fade Resistance: Engineered to withstand rapid heat buildup during continuous stopping cycles without losing braking torque or glazing the friction surface.
  • Precision Splined Internal Hub: Features precision-machined internal splines/teeth for positive torque transfer to the drive shaft, preventing hub shearing under heavy emergency braking loads.
  • Low-Wear Surface Profile: Optimized matrix density reduces lining wear while protecting opposing metal pressure plates from excessive scoring or grooving.
The Groxx Advantage
The GRXFD800 Friction Disc is engineered to deliver zero-compromise braking performance when it matters most. By combining high-coefficient composite materials with exceptional thermal resistance, Groxx guarantees smooth, immediate load holding and extended service life for high-rise suspended access operations.
