• Transportation Industry:

  It is mainly used to secure loads on flat - bed trucks, trailers, and rail cars, preventing the cargo from shifting or falling during transportation. In the marine industry, it is also used to hold cargo on ships, ensuring the safety of the cargo during maritime transportation.

• Construction Industry:

  In construction projects, such as the transportation and installation of steel structures, concrete components, and large - scale construction machinery, Chain Ratchet Type Load Binders can be used to fix these heavy - duty components to ensure they remain stable during transportation and lifting.

• Manufacturing Industry:

  In factories and warehouses, when transporting and loading heavy equipment, parts, or large - scale products, this kind of load binder can be used to firmly fix the goods to ensure safe handling and transportation. For example, in the automotive manufacturing industry, it can be used to secure vehicle bodies or large - scale auto parts.

• Mining Industry:

  In mines, when transporting materials such as ore and equipment, ratchet - type chain tensioners are needed to ensure the safe transportation of materials. For example, in underground mines, they can be used to bind materials on mine cars to prevent them from falling off during transportation.

• Power Industry:

  During the construction and maintenance of power facilities, when transporting and installing power poles, transformers, and other equipment, Chain Ratchet Type Load Binders can be used to fix the equipment to ensure construction safety.

• Shipping and Lifting Operations:

  It can be used for the lifting and towing of boats and yachts. In addition, in some large - scale lifting operations, it can be used in conjunction with other lifting equipment to adjust the tension of the chain and ensure the stability of the lifted object.

1、 Preparation work

1.1CHECK DEVICE STATUS

Confirm that all components of the tensioner are intact, including the ratchet, pawl, hook, and safety buckle, without deformation, cracks, or wear; The chain matches the specifications of the tensioner without any issues such as breakage or severe corrosion.

Ensure that there are no obstacles in the operating area, the goods are placed steadily, and the hanging points (such as truck guardrails and cargo lifting rings) are firm and reliable.

1.2Connect the chain and hook

Hang the hooks at both ends of the tensioner onto the fixed points of the chain or cargo/transport vehicle, ensuring that the hooks are fully engaged and securely fastened to prevent detachment.

2、 Tighten the chain (tightening operation)

2.1 Adjust the initial state of the ratchet wheel

If the ratchet is in the locked position, first shift the pawl to the "release" position (usually by pressing or pulling the control lever on the pawl), so that the ratchet can rotate freely.

Pull the chain and manually pre tighten it as much as possible to reduce the workload of subsequent mechanical tightening.

2.2 Activate the ratchet to tighten

Reset the pawl to the "tighten" position, hold the ratchet handle, and shake it up and down repeatedly.

Each time it is shaken, the ratchet will drive the threaded device to rotate in, and the chain will gradually tighten until it reaches the required tension (adjusted according to the weight of the goods to ensure that the goods are stable and not shaking).

3、 Locking and fixing

When the tension of the chain is appropriate, stop shaking the handle, and the pawl will automatically engage with the ratchet teeth to achieve self-locking and prevent the chain from loosening.

Some models require manual confirmation of the locking status to ensure there is no risk of accidental release.

4、 Release the chain (unloading operation)

4.1 Unlock

Press and hold the safety button or control lever on the pawl, turn the pawl to the "release" position, and release the ratchet from the locked state.

4.2 Slowly release tension

Slowly shake the handle in reverse, or gently pull the chain to allow the threaded device to spin out, gradually releasing the chain tension (do not release quickly to avoid danger caused by chain bouncing).

4.3 Dismantling equipment

After the tension is completely released, open the safety buckle of the hook, remove the tensioner and chain, and complete the operation.

5、 Precautions

It is strictly prohibited to stand in front of the chain or tensioner during operation to avoid sudden release of tension that may cause components to pop out and injure people.

Overloading is prohibited and the Working Load Limit (WLL) indicated on the equipment must be strictly followed.

If any abnormal noise, jamming or component abnormality is found during the operation process, stop the operation immediately and check. Only after troubleshooting can it continue.

1、How to choose a suitable ratchet type chain tensioner?

Core basis: It is necessary to match the chain specifications (diameter or grade, such as 8mm-16mm chain, 70/80 grade chain) and the weight of the goods.

Key parameters: Refer to the Working Load Limit (WLL) of the product to ensure that it is greater than the weight of the goods and the fracture strength is not less than 2-3 times the WLL to leave a safety margin.

Scenario adaptation: Light goods can choose WLL models of 1-3 tons, while heavy industrial transportation requires models of 5 tons or more.

2、What could be the possible reason for the chain suddenly getting stuck or unable to tighten during operation?

2.1 Common reasons:

Foreign objects (such as dust and rust) on the ratchet or pawl can cause jamming;

The pawl is not fully pulled to the "tighten" position and cannot engage with the ratchet teeth groove;

The chain is too loose or tangled, resulting in uneven force distribution;

Component wear (such as deformation of ratchet teeth and breakage of claws).

Solution: Stop the operation and clean up foreign objects; Check if the pawl gear is correct; Organize the chain and reattach it; If the components are damaged, they need to be replaced before use.

3、Can the tensioner be used for overloading? What are the risks?

Overloading is absolutely prohibited.

Risk:

May cause the main body and chain of the tensioner to break, resulting in the detachment of goods and causing transportation accidents;

Overloading can accelerate component wear, reduce equipment lifespan, and even cause ratchet/pawl failure leading to sudden release.

Tip: Always use within the WLL range. For heavy goods, it is recommended to use multiple tensioners to distribute the load.
