Core Advantages & Components

• Compact and Modular Design
Engineered for tight spaces, the hoist body allows quick access to components—ideal for fast servicing and minimal downtime.
• High-Quality Motors
Squirrel-cage induction motors, conforming to IS-325, are used. These crane-duty motors feature TEFC/TESC enclosures and are built for continuous starting, reversing, and braking.
• Robust Gearbox
Equipped with helical/spur gears made from hardened alloy steel, running in oil-bath lubrication with anti-friction bearings for consistent torque.
• Safe Braking Mechanism
Fail-safe electromagnetic AC/DC brakes hold full load safely—even during power failures.
• Forged Wire Rope and Hook
o Hooks are forged per IS-3815 with thrust bearing support
o Rope drums are grooved; wire ropes are high-grade plongh-steel per IS-2266
