An adjustable lifting beam is an industrial lifting device that allows the lifting points to be moved to different points along the length of the beam. This feature makes it particularly suitable for handling pieces of different sizes and weights on the same lifting device. This adjustability significantly improves production flexibility and reduces the number of lifting devices required, as one beam can be used for several different lifting tasks.
What is an adjustable lifting beam in industry?
An adjustable lifting beam is a lifting device in which the lifting points can be moved longitudinally according to the centre of gravity of the object to be lifted. This allows safe and balanced lifting of objects of different sizes without the need for separate lifting equipment.
The basic construction of the lifting beam consists of a strong steel beam with integrated sliding or lockable lifting points. The adjustment mechanisms can be manual or automatic depending on the requirements of the application. The beam is typically marked with a graduated scale to facilitate accurate positioning of the lifting points.
Hefmec lifting beams, such as the OptiBeam series, represent the most advanced technology in the industry. The lifting points can be adjusted without tools, which significantly speeds up production processes. In the demanding applications of mechanical engineering, this feature is particularly valuable when the sizes and shapes of the parts to be lifted are constantly changing.
How does the lifting beam adapt to the needs of different weight categories?
The lifting beam adapts to different weight classes by adjusting the distance between the lifting points and selecting the beam with the right lifting capacity. For lighter items, the lifting points are placed closer together, while for heavier and longer items the points are moved further apart.
The operation of the adjustment mechanisms is based on lockable sliding carriages or threaded adjustable lifting points. Lifting capacity is optimised by selecting the right beam size and model for the application. Safety factors are taken into account in the sizing of the beam and each beam is tested with a test load above the nominal load.
Hefmec’s tailor-made solutions meet the specific needs of customers. The OptiBeam range of beams covers weight categories from 1000 kg up to 200 tonnes. The requirements of production lines are taken into account individually and the beams can be equipped with different lifting points such as hooks, links or customized gripping solutions.
| Lift bar type | Weight class | Adjustment features | Typical applications |
|---|---|---|---|
| OptiBeam | 1000-5000 kg | Tool-free adjustment, integrated measuring scale | Machine parts, steel bundles, concrete beams |
| OptiBeam HEAVY | Over 5000 kg | Reinforced profile, precision adjustment | Prefabricated construction, steel industry |
| FixedBeam | 1000-200 000 kg | Fixed lifting points | Tubes, cylinders, standard size pieces |
Why is controllability critical for production flexibility?
Adjustability is critical for production flexibility, as it allows a single lifting device to be used for several different lifting tasks. This reduces the need to invest in separate lifting equipment and significantly speeds up product changeovers.
Production efficiency is improved when an adjustable lifting beam system can handle different sized pieces without changing lifting equipment. From a production engineering perspective, this means less downtime and better lead times. Quick product changes can be made in minutes, compared to hours with traditional methods.
It is this flexibility that underpins Hefmec’s agile solutions for production development projects. When the production line is used to produce pieces of different weights and sizes, the adjustable lifting beam adapts to every situation. This is particularly important in modern production, where small batch sizes and customisation are commonplace.
What safety features should be considered in lifting beams?
The safety features of the lifting beams must take into account the CE marking, the requirements of the Machinery Directive and the overload protection. Each lifting beam must be tested and certified as suitable for its intended use before being put into service.
Safety standards require the lifting beam to withstand at least five times its rated load without breaking. Safety at work is ensured by automatic safety features such as lockable lifting points and clear load markings. Overload protectors prevent the beam from being used beyond its capacity.
Hefmec’s lifetime guarantee for lifting blocks is based on high quality and careful design. Each beam is delivered with full documentation, including operating instructions, inspection reports and CE declaration of conformity. Responsibility for the safety of our products is a key part of our philosophy, which is why we place particular emphasis on the development of safety features.
Key benefits of the adjustable lifting beam – summary
The main benefits of the adjustable lifting beam for handling different weight categories are flexibility, safety and cost-effectiveness. A single device replaces several fixed lifting beams, reducing investment costs and the need for storage.
Hefmec’s holistic approach to solving customer problems is reflected in the design of the lifting beams. Each solution is based on the customer’s actual needs, and the lifting capacity is sized just right. This ensures that the investment is technically and economically optimal.
Improving productivity with an adjustable lifting beam is tangible and measurable. Product changeovers are faster, safety is improved and staff satisfaction is increased when lifting operations are effortless. In the long term, the return on investment is reflected in reduced maintenance requirements, higher utilisation rates and more flexible production.
An adjustable lifting beam is an investment in the future. It allows production to evolve according to changing needs without major additional investment. By choosing the right lifting beam, you are ensuring the flexibility and competitiveness of your production for years to come.
