Caldwell Expands RUD ACP-Turnado Lifting Point Range #manufacturing #industrynews #liftingpoints #expansion

Rockford, Illinois-based The Caldwell Group Inc. has expanded its series of RUD ACP-Turnado lifting points, with Max and Supermax versions.

Caldwell partners with the RUD Group to unite their sales and marketing activities in North America for RUD material handling and lifting devices within a common organization. The RUD portfolio includes slings and lifting points for the most complex tasks for integration into almost any application.

A lifting point is the connection between the lifting gear and the load. It connects the load with the lifting gear both during lifting and rotation as well as during turning and movement of loads. Lifting points include ring lifting lugs, eyebolts, flanges, etc., that the sling is attached to by using hooks, shackles, or other connection elements.

ACP stands for automatic center point; the RUD ACP-Turnado’s lift shackle immediately turns in the load direction automatically when it is lifted, so it cannot remain in an incorrect position. Dangerous transverse loads and a sudden drop of the load are excluded, thanks to a unique spring mechanism.

With the relaunch, RUD has gone one step further in terms of working load limit (WLL). The smart ACP-Turnado lifting point is now available from M8 to M100 as well as ½” to 4″, each with all the well-known advantages of the concept. This means that a suitable solution is now available for an even greater variety of applications, including extreme heavy-duty use.

The RUD ACP-Turnado Max (launched in April) brought to market M48, M52, M56 / UNC inch threads in size 2″ and the Supermax, the M64, M72, M80, M90 and M100 / UNC inch threads in sizes 2 ½”, 3″, 3 ½” and 4″. The family is now available with metric threads in diameters M8, M10, M12, M16, M20, M24, M30, M36, M42, M48, M52, M56, M64, M72, M80, M90 and M100 as well as with UNC inch threads in sizes ½”, ⅝”, ¾”, 1″, 1 ¼”, 1 ½”, 1 ¾”, 2″, 2 ½”, 3″, 3 ½” and 4″.

A practical feature of Max and Supermax versions is the deflector disc, which makes the user’s work easier. It is equipped with an angle marking and thus enables a quick, simple assessment of the current stop angle. The disc also displays important information for the user such as the WLL specification in “t” and “lbs”, the design factors 4:1 and 5:1, as well as the torque moment. Thanks to this, the ACP-Turnado fulfils the requirements of the American standard ASME B30.26. Furthermore, wear lenses are installed at the critical points of the power transmission, making it easy to assess whether the lifting point has already reached discard maturity.

Smart lifting point

Robert Allen, outside sales manager for the RUD product line in the U.S. and Canada, said: “Since the ‘smart’ centric lifting point automatically turns into the correct load direction when the load is lifted, the lift bail cannot remain stationary, and a sudden drop of the load is not possible. The innovative spring mechanism is the actual heart of the ACP-Turnado. It provides its unique ‘intelligence’ and makes it a ‘smart’ lifting point.”

The RUD catalog covers products from solid chains to diverse screw variants and includes items that are manufactured for use in specific end-user markets.

Allen added: “RUD lifting points, like other products, have stood for top quality, ergonomics, and safety in lifting technology and load securing for more than 35 years. More than 700 tested boltable and weldable lifting point variants in load ranges up to 250 ton meet maximum requirements in all areas of application in combination with the unique variety of application of our ICE and VIP chain systems.”

As with smaller RUD ACP-Turnado lifting points, large versions have a universal bolt head with internal and external hexagon, which enables optimum handling. The bolt is captive, but still replaceable, which useful in many applications. In addition, there is an adapted thread length for each dimension instead of a standard thread length across several sizes.

Jürgen Grubmüller, marketing director at RUD, said: “This concept allows us to offer fully customized thread types, thread sizes as well as thread lengths even in smallest batch sizes. Even customized special threads or special lengths up to 300mm are possible; this means that each of the three designs…is optimally matched to a defined [WLL] range and individual requirements.”

  • RUD ACP-Turnado Max and Supermax will be in stock at Caldwell and ready for shipping within the U.S. by the end of July.
