Centrifugal Brake
Groxx Traction Hoist Safety Components | GGRXCB800 Centrifugal Brake
The Groxx GGRXCB800 is an autonomous mechanical safety brake engineered specifically for 800 kg capacity traction hoists. Designed to act as an independent overspeed protection system, the GGRXCB800 automatically limits descent velocity in the event of power loss, primary brake failure, or emergency manual lowering. Operating purely on mechanical inertia without requiring external power, it provides a crucial layer of passive safety for suspended access platforms and swing stages.
Primary Functions
Overspeed Velocity Control: Automatically engages when descent speed exceeds rated operational limits, using centrifugal force to arrest excess velocity and regulate fall speed.
Controlled Emergency Lowering: Allows operators to safely lower suspended platforms to the ground during total jobsite power outages via manual brake release.
Fail-Safe Mechanical Operation: Operates completely independent of electrical systems, sensors, or primary motor controls, ensuring continuous availability during power disruptions.
Kinetic Thermal Dissipation: Absorbs and dissipates the kinetic energy of the descending 800 kg load through controlled friction, preventing free-fall acceleration without causing sudden, violent structural shocks.

Key Technical Features
Precision Flyweight Actuation: Calibrated internal flyweights deploy outward against static friction drums as rotational speed rises, providing proportional braking force matched to speed.
Thermal Dissipation Geometry: Enclosed in a finned alloy housing designed to radiate friction heat rapidly away from internal components during long controlled descents.
Non-Asbestos Friction Linings: High-friction composite pads deliver stable brake torque across extreme temperature gradients without glazing or fading.
Dust & Moisture Shielding: Fully enclosed housing prevents concrete dust, water, paint overspray, and environmental grit from contaminating internal flyweight pivots and friction surfaces.
The Groxx Advantage
The GGRXCB800 Centrifugal Brake provides peace of mind when operating at extreme heights. By combining precision flyweight engineering with robust thermal management, Groxx ensures that uncontrolled descents are prevented automatically—protecting workers, equipment, and structural assets under all power and emergency conditions.
