  • Offer Profile

  • We design, manufacture and market core shafts, expanding chucks and handling equipment. Our trademark is AMAL-SHAFT® and LionGrip®, which stands for optimal handling, quality, service and economy for the customer.

    The main area of use for our core shafts and expanding chucks are to carry the reel when unwinding or rewinding different materials. By infusing air into the core shaft it expands and the reel is locked on to the core shaft, so that the reel can be braked or rewound.
    Materials that are rolled on our core shafts are for example paper, cardboard, textile, tapes, labels, films and metal.
    Our customers are mainly found within the paper, converting, graphic and textile industries.
    With more than 50 years of experience of reel handling, you can trust in us—in the reel world.

    We have now become ISO certified in Environmental resource management, quality management and occupational health and safety

Product Portfolio

  • Technology at the core

      • Lifting Equipment

      • Industrial lifting equipment

        Our smart lifts make your heavy lifts light. Thanks to the force sensitive handle, our lifts follow your lightest movement. With our smart lifts you don’t have to worry about balancing and you can even lift outside the center of gravity.

        A lot of built-in functions and presets in our lifting aids guarantee both safety and effective handling.

        If you wish, we can even help with the development and production an easy-to-use, robust and well-adjusted gripper for your application. (But you can of course just buy the lift and make the gripper yourselves.)

        Our engineers will help you to find the best solutions for your specific needs.

        We invent, you lift!

          • Liongrip®

          • With our lifting device LionGrip® you are able to lift large loads in combination with long reach. The load can be gripped outside the center of gravity. LionGrip® is equipped with a force-sensitive handle and lifts smoothly at the smallest hand movement.

            Where traditional lifting equipment fails, LionGrip® gets the job done. You can for example easily load a machine from the side.

            Our unique lifting device makes your handling weightless and spares your employees’ backs and shoulders.

            A smart lifting device

            The LionGrip®’s smart force-sensitive handle makes sure the lifting arms follow your slightest movement up and down.

            The smart lifting device LionGrip® is easily adapted for different applications. On the circuit board, there are a lot of built-in functions and presets, that, in combination with custom-made grippers guarantee both safety and optimal handling.
            Examples are: limitation of lifting power, locking of gripper jaws when load is in air, blowing clean the air channels for vacuum grippers, and so on.

            Because of the robust and clean design, this lifting device demands a minimum of maintenance and spare parts, which makes it inexpensive to own.

            The installation of a LionGrip® is easy and takes little time. To move it is not much work.

          • AirHandle

          • AirHandle is a pneumatic lifting aid for loads up to 150 kg. AirHandle provides a simple and dependable handling because it follows the operator’s slightest move and offers high precision.

            The AirHandle can be mounted in ceiling rails or on a framework construction with folding arms.

            When the handle is not used, the load is balanced and can easily be moved up or down by holding the load itself.

            Grippers are easily changed with our quick tool change unit. Multiple safety functions prevent the load to fall or the lift to be used improperly.

            AirHandle has few moving parts, which gives a lifting aid with high reliability.

            Your new lifting equipment

            In the film you can see the easy and intuitive handling of the lifting aid AirHandle.

            Please note how the AirHandle responds to the slightest hand movement and how it is impossible to release the load when it is not resting on a support.

            Scrolling down will show you our different configurations.

        • Grippers for our lifting devices

        • We sell a lot of different grippers. We have standard solutions and we develop specially designed solutions for your specific needs. We have a team of experienced development engineers.

          In our assortment there are among others vacuum grippers, magnets and clamp grippers.

          For special applications outside our standard assortment, our experienced engineering team can produce new solutions which will speed up your handling process.

            • Roll handlers

            • In our product assortment we have both our own roll handlers for Liongrip, and roll handlers from other manufacturers, depending on your company needs.
              Contact us with your specifics and we will find the fitting product.

              Roll handler for Liongrip
              Our custom-made roll handler for Liongrip eliminates the need for balancing. This handler is perfectly fitted for (for example) loading load small rolls fast and easy on a pallet.

              The roll handler is built for up to 100 kg rolls, depending on roll width and Liongrip’s arm length and stroke.

              Roll handler for chain lift
              We sell, among others, Schlumpf’s and HT Lifting System’s roll handlers in a lot of variations, both manual and driven. You’ll get great performance for a competitive price.

            • Vacuum grippers

            • Vacuum is often the right way to grip different materials and products. We have solutions for both smooth and porous materials, for sacks, boxes, panels etc.

              More than one vacuum pump may be needed with porous surfaces. With those materials we would like to perform tests to secure the functioning.

              When used in combination with our lifts Liongrip and AirHandle, smart safety functions are activated; you are not able to lift without adequate vacuum and cannot release the load in-air.

              Our team of creative engineers are ready to design the vacuum gripper you need.

              Vacuum lift for irregular surfaces
              If your product has irregular surfaces we will furnish the gripper with flexible cups with a large stroke.

              Tilting or rotating gripper
              We will design your gripper in a way that the load can be tilted and/or rotated step-by-step or smoothly.

              The movement can be electrically or pneumatically driven, depending on your requirements.

              Our team of experienced engineers will help you in finding the best solution for your specific needs.

              Vacuum gripper for heavy loads
              Even big and heavy products can be handled with vacuum.

              To the right you can see a 200kg-product handled with one of our custom-made grippers. This specific gripper can rotate 180°.

              AHG-P-MVG Modular vacuum gripper
              This very flexible vacuum gripper can be adapted easily to your product. Number of cups, type of cup and positioning can be changed with some easy motions.

              In the circuit board of our smart lifting devices LionGrip® and AirHandle, a lot of built-in presets and functions provide a safe and smooth handling.

              Available dimensions:
              Length: 120, 300, 500, 750 and 1000mm
              Width: 120, 150, 350, 450 and 550mm

              PD Gripper
              With this gripper you can lift details with irregular surface while getting enough vacuum even if not all the holes are covered. You can grip over screws, holes and other irregularities.

              Under the housing a foam made of cellular rubber is attached, with small holes in it. This makes that the PD Gripper works where other grippers are inadequate.

              Please contact us for more information and quotation.

            • Other grippers

            • Over the years, we have developed a variety of grippers for different handling situations and loads. Several of these have become standard products in our range of grippers.
