C Hook

The C Hook is used for lifting and lowering various materials such as steel coils, paper rolls, rubber rolls, and more, with an outer diameter up to 20,000mm, an inner diameter up to 700mm, and a load capacity of up to 35 tons. The C Hook is customizable to meet specific customer requirements, including material type, coil diameter, load capacity, and lifting height.

Additionally, the design of the C Hook can be adjusted to be compatible with cranes, gantry cranes, and overhead gantry cranes, enhancing its efficiency and functionality. For a deeper understanding of this equipment, read further in the article provided by Gầu Ngoạm Sơn Tùng!

Description of C Hook Features

The C Hook is designed with a curved radius, equipped with protective padding and a rotating motor to prevent indentations or scratches when lifting or lowering steel coils. It may also include counterweights to ensure the balance of the lifted material and the hook along a straight line.

The C Hook is a special device used for lifting and lowering large steel coils (steel roll sheets) with substantial sizes and weight. Available in models such as 6-ton, 10-ton, and 15-ton capacity, the C Hook is suitable for lifting steel coils weighing up to 15 tons, with coil widths ranging from 1 meter to 1.4 meters.

C Hook Structure:

• The body of the hook is shaped like a "C" or "U" with a box-shaped cross-section.
• Counterweights are incorporated into the design.
• The lifting eye (hook eye).
• A rubber layer is placed between the hook's lower surface and upper side to create a curved radius, minimizing shock during contact.

The most important feature of the C Hook is its ability to maintain balance, whether loaded or unloaded.

Materials for C Hook Manufacturing:
The C Hook is typically made from specialized steel materials used for lifting equipment, such as Q235 steel (China), SS400 steel (Japan), or equivalent. Additionally, the C Hook is designed in compliance with the standard TCVN 4244 - 2005 (Vietnamese standard).

Available Load Capacities for C Hooks:
C Hooks are available in a range of load capacities, including:

• C Hook-6 tons
• C Hook-10 tons
• C Hook-15 tons
• C Hook-20 tons
• C Hook-25 tons
• C Hook-30 tons

Additional options are available depending on the weight and size of the steel coils being handled.

Inspection Requirement:
C Hooks must undergo load testing at 200% of their rated capacity. For example, a 30-ton C Hook must pass a test with a 60-ton load within a specified period to ensure its safety and reliability.

Applications of C Hook Today

• Rising Demand in Import-Export Operations: The demand for goods import and export is increasing rapidly, especially in businesses dealing with steel products. These items are heavy, bulky, and large in size. Handling these products—such as loading and unloading them onto 20-foot or 40-foot containers—is not an easy task.

• Challenges with Manual Labor: Relying solely on manual labor can be very labor-intensive, and the efficiency is often low. Moreover, setting up and executing the loading or unloading process for a container can take a long time and poses significant risks in terms of labor safety.

• Limitations of Other Equipment: Other equipment, such as mobile cranes or forklifts, typically assist in organizing and removing goods but are not the main tools for the job, especially when dealing with long steel bars (up to 11.6 meters) or bundles of sheet metal that are 6, 8, or 10 meters long. These machines are less effective in such situations.

• C Hook for Optimal Solution: To address these challenges, the C Hook with a 1.5-ton capacity has become a popular solution for lifting and lowering goods into containers. Its design makes it ideal for handling heavy, large-sized materials efficiently.

• Positioning for Effective Use: The C Hook is placed beneath the overhead crane hook or gantry crane (lifting device) in the workshop, allowing it to perform the loading and unloading tasks effectively and safely.

Notes When Using the C Hook

The C Hook crane has a large hook capacity, is easy to assemble, highly mobile, and requires low maintenance. However, to ensure its durability and optimal performance, users should follow these guidelines:

• Only hook or lift/lower loads that are within the device's rated capacity.

• When attaching the C Hook to the hook of the lifting motor, ensure it is securely fastened.

• Use high-quality, reliable hook chains to secure the load.

• After completing the task, remove the hook and fold the main equipment when not in use.

• Do not use the equipment for any purposes other than its intended function.

• Store the C Hook crane in an appropriate location to prevent wear and tear.
