For 20-, 25-, or 50-kg bags, you need a lifting aid that’s suited to the weight, the shape of the bag, and how often you lift. For lighter bags up to 25 kg, a simple mechanical lifting aid is often sufficient, while 50-kg bags typically require a vacuum lifter or a similar ergonomic system. In this article, we answer the most frequently asked questions about bag lifting aids so you can quickly make the right choice for your situation.
What weight determines which lifting aid you need?
The weight of a bag is the first and most decisive factor in choosing a lifting aid. In many countries, bags weighing up to 25 kg are still legally considered within the manual lifting limit for trained workers; however, when lifted repeatedly throughout a full workday, they still pose a serious risk of back injury. For weights of 25 kg or more, mechanical assistance is strongly recommended, and for 50-kg bags, a full-featured bag-lifting aid is indispensable.
In addition to weight, the lifting technique, lifting height, and lifting frequency also play a role. An employee who lifts a 20-kg bag ten times a day has a different risk profile than someone who handles hundreds of bags a day. Ergonomic lifting is therefore not just about the weight itself, but also about the cumulative strain over an entire shift.
What are the most commonly used lifting aids for bags?
The most commonly used lifting aids for handling bags are vacuum lifters, mechanical lifting devices, and balancing devices. Each system has its own area of application, depending on the weight, the material composition of the bag, and the work environment. For a complete overview of available solutions, please visit the page on bag handling.
- Vacuum lifters: Ideal for sealed, non-porous bags. They lift the bag using negative pressure and allow for precise positioning without requiring physical effort from the operator.
- Balancing devices and hoists: Suitable for heavier bags where the operator guides the bag, but the weight is supported entirely by the system.
- Mechanical lifting aids: Easier to use and less expensive to purchase, but less suitable for heavy loads or frequent lifting.
The choice between these systems depends heavily on the specific work situation. A vacuum lifter for bags works exceptionally well in a structured production environment, while a balancing device offers more flexibility in varying situations.
When is a vacuum lifter the right choice for bags?
A vacuum lifter is the right choice for bags when the bag has a smooth, sealed exterior and when speed and precision are important. Bags made of plastic, laminate, or tightly woven material are well-suited for vacuum lifting. For porous materials such as jute or open-weave fabrics, a vacuum lifter is less suitable because the suction force cannot generate sufficient grip.
A vacuum lifter for bags is also particularly useful when bags are repeatedly lifted, rotated, or stacked at a fixed workstation. The operator does not need to exert any force, which drastically reduces physical strain and minimizes the risk of injury. In environments where 25-kg or 50-kg bags are moved several times an hour, a vacuum lifter is therefore one of the most efficient investments in ergonomic lifting.
How does lifting 20-kg bags differ from lifting 50-kg bags?
Lifting 20-kg bags differs fundamentally from lifting 50-kg bags in terms of risk, required equipment, and legal obligations. With 20-kg bags, manual lifting is still possible using the proper technique and at a low frequency, but with 50-kg bags, mechanical assistance is mandatory in virtually all cases and necessary to prevent serious back injuries.
Lifting aid for 20-kg bags
For 20-kg bags, a simple mechanical lifting aid or a lightweight balancing arm is sometimes sufficient. However, caution is still advised here: the risk increases rapidly with high lifting frequencies or unfavorable lifting positions (such as bending over or twisting). A lifting aid designed for 25-kg bags can often be used for 20-kg bags as well, making the investment even more cost-effective.
Lifting aid for 50-kg bags
For 50-kg bags, a sturdy lifting aid is essential. The preferred option here is a vacuum lifter with sufficient lifting capacity or a balancing device that supports the entire weight. The operator guides and positions the bag but no longer has to lift anything themselves. This not only protects the employee’s health but also significantly increases the handling speed.
Which lifting aid is right for your workstation and production environment?
Choosing the right lifting aid for bags depends not only on the weight, but also on the layout of the workstation, the available space, the turnaround time, and the nature of the product. A fixed workstation in a warehouse requires a different solution than a mobile work environment or a production line where bags are processed continuously.
Relevant questions to help you make the right choice:
- How often are bags lifted per hour or per day?
- What is the exact lifting height and the distance over which the bags are moved?
- Is the workstation fixed or does it change locations?
- What is the bag made of: smooth, porous, filled with powder, or a granular product?
- Are there any space constraints that affect the choice of system?
By systematically answering these questions, you can make an informed choice that benefits both safety and productivity. Be sure to also browse the broader product catalog to get an idea of the available systems and their applications.
How do you safely maintain a bag-lifting aid?
Proper maintenance of a bag-lifting device involves performing regular inspections of the suction cups, hoses, connections, and lifting mechanism. A good maintenance program extends the device’s service life, prevents unexpected breakdowns, and ensures that the operator’s safety is maintained at all times.
Specific maintenance points for vacuum lifters and similar lifting systems:
- Check suction cups regularly for wear or tears, because a damaged suction cup loses its grip and poses a safety hazard.
- Inspect hoses and couplings for leaks, especially in systems that use compressed air or a vacuum.
- Lubricate moving parts according to the manufacturer's recommendations.
- Perform periodic load tests to verify that the system can still handle its full rated lifting capacity.
- Record all maintenance activities in a logbook to ensure traceability and compliance.
A maintenance contract through a specialized supplier offers added peace of mind, because preventive maintenance is scheduled before problems arise. You can find more information about service solutions on the service page.
