Our Best-Selling Crane Accessories Types

Crane Wheels

Crane wheels are the most important parts in crane traveling system which are also the most vulnerable crane parts due to the friction between crane wheels and rail. The crane wheels should be replaced when the flange wear, flange breakage and fatigue pitting happened.

Lifting Hook

A lifting hook is a device for grabbing and lifting loads by means of a device such as a hoist or crane. A lifting hook is usually equipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached.

Pulley Block

Pulley block is a simple machine composed of a plurality of movable and fixed pulleys, its working principle is mainly based on the characteristics of movable pulleys and fixed pulleys, movable pulleys can save force, but can not change the direction of force; The fixed pulley can change the direction of the force, but not the effort, the combination of the two, the pulley set can save effort and change the direction of the force.

Hoist Drum

An important part of lifting equipment, used for lifting mechanism of wire rope winding, by the drum, drum shaft, gear disc, drum hub, bearing body, bearing composition.

Smooth operation, making the crane smooth and smooth during movement, helping to ensure the accuracy and safety of lifting operations.

Adapt to a variety of working conditions, with a solid and reliable structure, safe and durable.

Manufacturing Process of Crane Wheels

Heating the Metal

The manufacturing process starts with heating high-quality steel billets to a temperature where they become malleable.

Forging Under Pressure

The heated billet is then placed under a hydraulic press that applies extreme pressure, shaping the billet into a wheel. This process enhances the crane wheel’s internal structure, improving its strength.

Heat Treatment and Hardening

Once the crane wheel is forged, it undergoes heat treatment to increase hardness, making it resistant to wear and capable of enduring high loads.

Finishing and Quality Control

The final step involves precision machining and strict quality control checks to ensure the crane wheel meets industry standards.

Lifting Hook Structure Type

Eye Hooks

Eye hooks feature a secure loop or “eye” at the top, making it easy to connect them to slings, latches, or other lifting accessories. They are ideal for general lifting tasks and compatible with a wide range of rigging equipment.

Clevis Slip Hooks

These hooks have a U-shaped connection point with a removable pin, allowing quick and secure attachments. Clevis slip hooks are commonly used with chain slings and wire rope slings, offering versatility and ease of use.

Swivel Hooks

Built with a rotating mechanism, swivel hooks allow the hook to spin (swivel) freely, reducing twisting and stress on the load and rigging, making them perfect for applications where loads must be turned or maneuvered during lifting.

Sorting Hooks

Designed with a long, narrow point to slip into easily and sort through loads such as logs, pipes, or bundled materials. They are commonly used in forestry, construction, and material handling industries.

Foundry Hooks

Foundry hooks have a wide throat and a notched or flattened tip, allowing them to handle large, bulky loads without slipping. They offer peerless performance for foundries, steel mills, and other heavy industries.

J-Hooks

Featuring a classic J-shape, J-hooks are well-suited for lifting and securing loads with curved or rounded surfaces, such as pipes, tubes, or tires. They are often used in transport and automotive applications.

Grab Hooks

With a narrow throat and clevis attachment, grab hooks are designed to hold chains tightly in place. They are typically used in chain sling assemblies and for load binding in transport and logistics.

Drum / Barrel Hooks

Specifically designed for lifting and handling drums, barrels, and similar cylindrical They securely grip the rim or chime of the container, allowing for safe and efficient material handling.

Packaging and Shipping

Packaging	Wooden box, PE film
Transportation methods	Road transport, rail transport, sea transport, air transport

FAQ

Q: What is the best material for crane wheels?

A: For most crane wheels, medium-carbon steel is the most commonly employed material, due to its wide availability and lower cost. As a general rule, the greater the carbon content of steel, the greater the hardness potential.

Q: What are the different types of crane wheels?

A: According to different standards, crane wheels can be classified into different types, such as, single edge and double edge crane wheels, casting and forging crane wheels, etc. In the following, single edge and double edge crane wheels will be introduced in length.

Q: How does a pulley block multiply force?

A: The force required to lift the load is approximately half of the load's weight, effectively multiplying the input force by 2. The more ropes supporting the load in a pulley block, the greater the force multiplication factor.

Q: What is the purpose of a hoist drum?

A: A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium.

Q: What are the rules for lifting hooks?

A: All crane and hoist hooks shall have safety latches. Hooks shall not be painted (or re-painted) if the paint previously applied by the manufacturer is worn. Crane pendants shall have an electrical disconnect switch or button to open the main-line control circuit.
