Engineering & Technical Overview
The PVC Coated 4MM Wire Rope (Make: Ushamartin) is a heavy-duty flexible geared coupling with an integrated precision-machined brake drum manufactured by CMK Electro Power for EOT crane hoisting and travel machinery. Combining high-torque crowned tooth internal/external gearing with a dynamically balanced high-grade cast steel brake drum, this coupling absorbs angular, radial, and axial shaft misalignments between the motor and reduction gearbox while providing a smooth, high-friction braking surface for thruster brakes.
Industrial Applications & Machinery
Connection between drive motor and gearbox on EOT crane main/auxiliary hoists.
Long-travel (LT) and cross-travel (CT) crane drive transmission lines.
Belt conveyors, ball mills, heavy winches, and rolling mill motor drives.
Heavy industrial gearboxes requiring synchronized mechanical power transfer and braking.
Direct replacement coupling for standard industrial brake drum assemblies.
Key Operational & Safety Benefits
Crowned Gear Tooth Geometry
Accommodates angular and parallel shaft misalignments without localized tooth stress.
Dynamically Balanced Drum
Precision CNC machined brake drum eliminates high-speed vibration and extends bearing life.
High Shock-Load Tolerance
Heat-treated forged alloy steel hubs withstand repetitive crane reversing cycles.
Sealed Grease Lubrication
Heavy-duty O-ring seals retain grease and lock out abrasive dust and moisture.
Zero Backlash Precision
Delivers immediate torque transfer and smooth, predictable brake shoe engagement.
