Eickhoff 3D-Lifting ring - Notes regarding the assembly

• Attachment points must be arranged so that they are easily accessible and do not hamper the fitting or removal of the attachment device.
  
  
• Lifting Rings must not interfere or touch other structural components. They must move freely in all directions.
  
  
• Lifting Rings must be fitted in manner that avoids any potentially dangerous situation to an operator such as squeezing, shearing, catching or impact points. Lifting Rings must not impede transportation by protruding beyond the side of the object to be transported.
  
  
• The attachment location must be chosen, so that the basic material withstands at least 2.5 times the carrying capacity of the Lifting Ring without permanent deformation and 4 times the carrying capacity until breakage. The minimum material thickness is fully dependent on the material physical characteristics.
  
  
• The number and arrangement of attachment points must ensure that the load does not change its position during transportation.
  
  
• The attachment contact face shall be clean, level and with a diameter larger than dimension F. The screw shall be tightened to the contact face with the torque specified on the data sheet.
  When it is intended for the Lifting Ring to be permanently attached to a structure, it has to be secured with a suitable thread-locking compound e.g. Loctite 243.
  
  
• Through hole attachment requires the use of nuts complying with DIN ISO 4032. After the nut is fitted, the minimum protruding lenght of the thread is 2 times the pitch.
  
  
• The thread depth for blind bores shall be at least ( see data sheet):
  
  

  Material	Thread depth
  steel	1.00 x Y
  cast iron	1.25 x Y
  aluminium	2.00 x Y
  aluminium-magnesium alloys	2.50 x Y

  
  
  
• A competent person at least once per year should check Lifting Rings, which are regularly used as load suspension means.
  
  
• Every Lifting Ring must be inspected before use. The condition of the threads, any evidence of corrosion, incipient cracks, deformation and free movability should determine the usability of the Lifting Ring.
  
  
• When multi-strand lifting equipment is used, the tractive force is increased per attachment post (see also DIN 5688, Part 3 - Carrying Capacity).
  
  
• Attachment point bores in dirty areas or in situations when the Lifting Rings are removed, should be protected by the use of closing screws. These attachment points should be color marked so that they are easily located and identifiable.
