Steel Drive Belt
Groxx Traction Hoist Components | GRXSB800 Reinforced Steel Drive Belt
The Groxx GRXSB800 is a high-tensile, precision-engineered steel drive belt designed for 800 kg capacity traction hoists. Engineered to deliver synchronous power transmission between the motor shaft and the primary traction sheave assembly, the GRXSB800 ensures zero-slip mechanical drive efficiency under heavy dynamic lifting loads. It is a critical replacement component for maintaining smooth, continuous vertical motion on suspended access platforms and swing stages.
Primary Functions
Synchronous Power Transmission: Transfers rotational torque directly from the drive motor/gearbox assembly to the traction sheave, ensuring immediate response without rotational slipping.
Heavy Load Distribution: Distributes high tensile loads uniformly across its internal steel cord core, maintaining operational stability under peak dynamic loads up to 800 kg.
Vibration & Shock Absorption: Dampens motor-induced vibrations and sudden dynamic load shocks during start-stop cycles, protecting internal gears and bearings.
Constant Speed Maintenance: Prevents pitch variance and stretching, maintaining consistent ascent and descent speeds for suspended platform stability.

Key Technical Features
Steel Cord Core Structure: Embedded with high-tensile helical steel cords that eliminate elongation and stretching, guaranteeing long-term dimensional stability and pitch accuracy.
Abrasion-Resistant Tooth Facing: Covered with a durable nylon/elastomer fabric layer that reduces tooth shear and minimizes friction-induced wear against drive pulleys.
Oil & Chemical Resistance: Formulated to withstand exposure to industrial lubricants, grease, cement dust, and harsh ambient weather conditions on construction sites.
High Fatigue Life: Engineered to endure high-frequency reverse-bending cycles around small-diameter hoist pulleys without cracking or delaminating.
The Groxx Advantage
The GRXSB800 Steel Belt delivers uncompromising torque transfer and operational safety for 800 kg hoist platforms. By reinforcing the belt matrix with high-tensile steel cords, Groxx eliminates stretch and tooth jump, providing reliable power transmission that keeps suspended access equipment running smoothly and safely.
