  • Even loading of bearings
  • Ease of Installation & Maintenance
  • Compact design
  • Self-braking system for holding the load in any position
Load Chain

Alloy steel chain Gr-80 as per IS: 6216 uniformly electrically resistance welded duly heat treated for ductility, toughness and wear resistance. Chains are accurately calibrated for smooth running in chain sprocket.

Hooks

Forged hooks as per IS: 8610/ IS : 15560 and fitted in upper-arm and bottom block made out of heavy duty malleable casting/S.G. Iron.

Ball - Bearings

Chain Pulley Block will have two ball / roller bearings for smoother running on load.

Load Chain Wheels

Load Chain Wheels are Made up of Malleable/S.G. Iron casting with accurate chain sprockets for smooth running of chain.

Gears

Gear blanks are made out of nickle-crome alloy steel. Accurately machined and teeth generated on hobbing machines for involute corrected for high bending stress and low wear. All gears are hardened and tempered for minimum wear.

Hand Chain Wheel

Accurately sprocket chain wheel made out of graded casting as per IS: 210 shall be provided.

Brake

Self actuating type load pressure brake of screw & friction washer type ensures safety at all the position.
