Product Parameters
Parameter | Details |
Model | Available in various models to meet different application needs. For example, some models are specifically designed for light - duty vehicle towing, while others are suitable for heavy - duty industrial use. Specific model numbers may include [List some common model numbers if applicable] |
Material | - Main Body: High - strength alloy steel such as 40Cr or 35CrMo. These materials offer outstanding tensile strength, ensuring the shackle can withstand significant pulling forces without deformation or breakage. - Surface Treatment: Usually undergoes processes like hot - dipped galvanizing, electro - galvanizing, or powder coating. This not only enhances corrosion resistance, allowing the product to perform well in harsh environments including humid, salty, or muddy conditions, but also improves its wear resistance, extending the overall service life. |
Load Capacity | Comes with a wide range of load - bearing capacities. Common ratings include 1T, 2T, 3.25T, 4.75T, 6.5T, 8.5T, 9.5T, 12T, 13.5T, 17T, 25T, 35T, 55T, etc. It is crucial to select the appropriate load - capacity based on the actual towing requirements. Using a shackle with insufficient load - bearing capacity can pose serious safety risks. |
Size Specifications (Taking a 4.75T D - shaped Shackle as an Example) | - Width (W): Approximately 32mm - Diameter of the Ring Part (D): Around 22mm - Diameter of the Pin (d): About 19mm - Overall Length (including pin) (E): Roughly 46mm - Pin - related Dimension (P): Approximately 20.5mm - Overall Outer Dimension (S): Around 60.5mm Note: Sizes may vary slightly among different manufacturers and specific models. Additionally, custom sizes can often be provided according to customer needs. |
Color Options | Usually available in a variety of colors including red, black, blue, white, green, orange, etc. Red is a popular choice as it is highly visible, which can serve as a warning in towing operations, reducing the risk of accidents due to overlooked connections. |
Safety Factor | Generally designed with a safety factor ranging from 4:1 to 6:1. For instance, a shackle with a 4:1 safety factor and a rated load capacity of 4.75T can endure a breaking force of at least 4 times 4.75T under normal circumstances. This ensures reliable performance during towing, providing an extra layer of safety for users. |
Compatibility | Engineered to fit standard hitch receivers on a wide range of vehicles, such as SUVs, off - road vehicles, trucks, etc. It can also be easily connected to trailer arms, towing ropes, and other towing accessories, making it a versatile component in towing systems. |
Weight | The weight varies depending on the load capacity and size. For example, a 4.75T D - shaped shackle might weigh around 0.99kg. However, this is just an approximate value, and the actual weight should be determined based on the specific product. |
Locking Mechanism | Equipped with a reliable locking device, typically a pin - and - clip system. The pin is made of high - quality alloy steel and features a thread - locking design. This prevents accidental loosening during towing, maintaining the integrity of the connection and ensuring the safety of the towing operation. |
Manufacturing Standard | Complies with international standards like EN (European Norm) and relevant US standards. It meets or even exceeds industry regulations regarding safety, durability, and performance, guaranteeing the quality and reliability of the product. |
Product Applications
This is the most core application area of trailer arm shackles. When a vehicle malfunctions (such as breaking down or accidents) and needs to be towed, the release buckle is used to connect the towing arm of the rescue vehicle to the towing hook or fixing point of the rescued vehicle, ensuring a stable rigid or flexible connection between the two vehicles and avoiding detachment during the towing process.
Suitable for rescue of different types of vehicles such as cars, trucks, and construction vehicles.
In auxiliary operations of cranes, loaders, excavators, and other equipment, trailer arm shackles can be used to connect slings, trailer arms, and heavy objects (such as steel, containers, and building components) to achieve lifting, dragging, or shifting of heavy objects.
Its high-strength characteristics (usually made of alloy steel) can withstand large loads and meet the operational requirements of heavy equipment.
In agriculture, tractors, harvesters, and other equipment are often connected to agricultural tools (such as plows, seeders) or transport trailers through trailer arms to achieve power transmission and connection fixation during field operations or material transportation.
In forestry, it can be used to connect wood transport trailers and towing equipment, drag and drop felled wood, and adapt to the complex terrain of the wild working environment.
During the temporary connection or loading and unloading process of freight vehicles (such as semi trailers and container trucks), trailer arm shackles can assist in securing goods or connecting temporary trailer structures to ensure the stability of goods or additional devices during transportation.
For example, in multi car formation transportation (such as multi car joint towing of heavy goods), the shackle is used to connect the trailer arms of adjacent vehicles, distribute the load, and maintain synchronization.
When off-road vehicles (such as off-road vehicles and ATV all terrain vehicles) are exploring or crossing complex terrain in the wilderness, if they get stuck, they can use the trailer arm to disconnect and connect to the towing rope or arm of the rescue vehicle to achieve self rescue or mutual rescue.
In addition, the connection between camping trailers, RVs, and towing vehicles may also use small trailer arm shackles to ensure safe and stable driving.
In towing operations on small vessels such as yachts and cargo ships, the trailer arm shackle can connect the trailer arm of the tugboat to the mooring point of the towed vessel, for the purpose of vessel displacement, berthing, or rescue.
In the port, it can assist in short distance towing of small goods or temporary connection and fixation of equipment.
Product Operate Guide
1、Check the condition of the components: Before use, check whether the trailer hook, trailer arm, and shackle are intact, whether the shackle is worn, cracked, or corroded, whether the safety lock buckle can work normally, and confirm that its load-bearing capacity meets the requirements of use.
2、Fixed trailer hook or winch: If you need to use a trailer hook or winch, you need to first secure it in the designated position of the vehicle.
3、Connecting trailer ropes or steel cables: Thread the shackle through the connection end of the trailer rope or steel cable, or hang it at the force center position of the trailer arm, and do not hang it at the hook tip. At the same time, it is necessary to ensure that both ends of the rope or steel cable are firmly tied.
4、Insert the pin shaft: Thread the pin shaft of the disassembly into the hole of the buckle body in the specified direction to ensure that it is inserted in place. For threaded shafts, they need to be tightened until there is no looseness.
5、Locking safety lock buckle: If the release buckle is equipped with a safety lock buckle, it should be locked with the safety lock buckle after installation to prevent accidental opening during use.
6、Final inspection: After installation is completed, conduct a comprehensive inspection of all components, manually pull and test or observe whether the shackles, ropes, etc. are loose to ensure correct installation.
FAQ
The selection should be based on the actual load (including static load and dynamic impact load), and the rated working load (WLL) of the shackle must be greater than or equal to the actual load-bearing capacity, and must match the size of the connecting components (such as trailer arms, ropes) (such as pin diameter, buckle opening width). At the same time, consider the use environment (such as corrosion, high temperature) and choose corresponding materials (such as ordinary alloy steel, stainless steel).
Rated working load (WLL): The maximum safe load that a shackle is allowed to withstand during normal use, usually indicated on the product (e.g. "WLL 5t").
Breaking load (BL): The minimum load at which the shackle breaks, usually 4-6 times the WLL, is a safety redundancy indicator and must not be used near the breaking load.
Not recommended for general use. Trailer arm shackles need to adapt to dynamic drag impacts, while lifting shackles focus on static lifting. The structural strength distribution and safety factor of the two may be different, and mixing them may lead to safety hazards.
First, check if it is stuck due to rust or foreign objects. You can soak a small amount of lubricating oil and gently shake the pin shaft; If it still cannot be disassembled, do not forcefully strike (which may cause deformation). It is recommended to replace the shackle with a new one to avoid forced operation causing breakage
