Bulk bags, also known as Flexible Intermediate Bulk Containers (FIBCs), are essential for the storage and transport of bulk materials. An optional feature that can enhance the functionality and safety of these bags is the lifting sleeve or tunnel loop. Read more to learn about what lifting sleeves or tunnel loops are, their benefits, and how they are used.

What is a Lifting Sleeve (Tunnel Loop)?

A lifting sleeve, often referred to as a tunnel loop, is a type of lifting mechanism designed for bulk bags. Unlike traditional lift loops that are attached to the corners or sides of the bag, lifting sleeves are continuous loops of fabric sewn along the top sides of the bulk bag, creating a tunnel-like structure through which forklift tines can be inserted.

How Does a Lifting Sleeve Work?

1. Design: Lifting sleeves run along the full length of the bag’s sides, forming a tunnel. This design allows the forklift tines to be easily inserted through the sleeves.

2. Operation: The operator aligns the forklift tines with the sleeves and drives them through the tunnels. Once the tines are fully inserted, the bulk bag can be lifted securely.

Benefits of Lifting Sleeves

• Enhanced Stability: The tunnel loop design provides a more stable lifting mechanism compared to traditional loops, as the weight is distributed more evenly along the sides of the bag.
• Ease of Use: Lifting sleeves simplify the process of engaging the bulk bag with lifting equipment, reducing the risk of misalignment and ensuring a secure lift.
• Safety: The continuous loop design minimizes the chances of the bag slipping off the forklift tines, enhancing overall safety during lifting and transport.
• Versatility: Lifting sleeves can accommodate various lifting equipment, making them suitable for different operational needs.

Applications

Lifting sleeves are particularly beneficial in industries where stability and safety are paramount. They are commonly used in:

• Agriculture: For transporting seeds, grains, and fertilizers.
• Chemical Industry: For handling bulk chemicals and powders.
• Food Industry: For moving food-grade products while ensuring minimal contamination risk.
• Construction: For transporting sand, gravel, and other construction materials.

Choosing the Right Bulk Bag with Lifting Sleeves

When selecting a bulk bag with lifting sleeves, consider the following factors:

1. Load Capacity: Ensure the bag is rated for the weight of the material you intend to transport.

2. Material Compatibility: Choose a bag made from materials that are suitable for the specific type of product you are handling.

3. Safety Standards: Verify that the bulk bag meets industry safety standards to ensure safe handling and transport.

Lifting sleeves, or tunnel loops, are an innovative lifting mechanism that can enhance the safety and efficiency of handling bulk bags. By distributing the weight more evenly and providing a secure grip for lifting equipment, these sleeves make it easier to transport and store bulk materials safely.
