What is a lifting point?
The unique variety from RUD.
Important for design engineers.
Loads are lifted using lifting means (chains, cables or synthetic slings) or lashed on the truck during transport. The different numbers of legs and their angles of inclination result in a multitude of loads and stress directions in the lifting or lashing points. In particular, the WLL of lifting points changes depending on symmetrical or unsymmetrical loads. The design of lifting points can be calculated using certain equations.
1-leg lifting process: load factor 1 (right-hand figure). The load can rotate, the lifting point twists open. Risk of falling! Choose a lifting point with ball bearing.
Good Points / Bad Points
Wrong lifting point, too small, poorly positioned, insufficiently fastened, no alignment in the force direction – in some circumstances with broken bolt: Many mistakes can occur when lifting or turning loads. These genuine pictures from practice show this.
Why PINK? – non-mix-up in pink!
Modern and tested lifting points increase health and safety at work and reduce handling times. Use tested lifting points from RUD “Made in Germany”!
Lifting points have to be marked with a special colour – in accordance with the basic principles for their testing and certification. For this reason, the RUD lifting points were painted the usual red more than 30 years ago in line with the standard used for the chain quality at the time.
20 years ago, RUD then launched the revolutionary “VIP” chain range in Grade 10 on the market – in fluorescent pink powder coating. The special feature of this paint: it can be used as an overheating indicator at the same time. The pink powder coating used in the VIP product range changes its colour at a temperature above 200 °C: from ochre to brown and – at the prohibited temperature of almost 400 °C – to black with blister formation. Thanks to this established system, overheated lifting points can be identified reliably and replaced.
By the way: the former RUD ICE chains of quality class Grade 12 or 120 are powder coated with the shade “ICE-Pink”. This legally protected colouring is used for all lifting points equipped with ICE-BOLT. ICE-Pink also serves as a heat indicator from 200 °C onwards; at 300 °C a black colour display becomes visible as a sign of overheating.
