Pulley Blocks

Cast Iron Pulleys

The load-bearing wheel that guides wire rope or chain in a lifting system. Kailipu offers four cast iron pulley types from 20 mm to 200 mm in diameter, covering single wheel awning, double wheel awning, rope block with hand wheel, and pulley block with forged hook, so a buyer can source all pulley needs for a rigging project in one order instead of managing multiple suppliers.

Who It Is For

Buyers Who Specify Cast Iron Pulleys

  • Rigging and lifting contractors building complete lifting sets for construction or infrastructure projects
  • Marine and offshore teams needing durable cast iron pulleys for deck winch systems and mooring setups
  • Cranes and hoist manufacturers integrating pulleys into custom lifting assemblies
  • Industrial maintenance teams replacing worn pulleys in overhead crane systems
  • Truck and trailer outfitters installing pulley blocks for tie-down and load securing systems
Problems Solved

What Cast Iron Pulleys Solve on the Job

  • A lifting system with mismatched pulley sizes because the supplier only stocks one size or pattern
  • A pulley that fails under load due to low-grade cast iron or poor casting integrity
  • No forged hook on a pulley block, forcing the user to add a separate hook and risk misalignment
  • A hand wheel pulley without a secure grip or durable bearing, leading to operator fatigue or slippage
  • A pulley with a non-standard bore size that does not fit the shaft or mounting hardware
  • Lack of a black cast iron finish, so the pulley corrodes quickly in outdoor or industrial environments

Answers

Cast Iron Pulleys FAQ

What is the working load limit for a cast iron pulley?
The working load limit is based on the minimum breaking load divided by the standard 4:1 design factor unless otherwise stated. It is stamped on the pulley body and listed in the product data sheet.
What is the difference between a forged hook and a rebar hook?
A forged hook is made from a single piece of steel with a high strength-to-weight ratio, suitable for heavy-duty lifting. A rebar hook is a bent steel bar, lower in strength, used for temporary or light-duty tie-downs.
Can I get a pulley with a custom bore size?
Yes. Custom bore sizes are available upon request. Provide the required shaft diameter and mounting configuration, and we will confirm feasibility with the manufacturer.
Is the cast iron finish standard or can it be changed?
The standard finish is black cast iron. Custom surface finishes such as zinc plating or powder coating are available for corrosion protection or colour matching.
Do you supply Material Test Certificates for cast iron pulleys?
Yes. A Material Test Certificate to EN 10204 3.1 is issued with the batch on request. All pulleys undergo proof load testing and dimensional checking before release.
Can you stamp our brand and tonnage on the pulley?
Yes. Custom tonnage stamping, private label marking, and branded packaging are standard options. Send the marking layout and pack configuration for confirmation.
What is the smallest order you accept?
We accept small top-up orders as part of a mixed rigging order. You can order one pulley type or a combination of all four types without needing a full container.
