General Information
Reference should be made to relevant standards and other statutory
regulations. Inspections must be carried out only by people who possess
sufficient knowledge.
Before installation and before every use, visually inspect the lifting points,
paying particular attention to any evidence of corrosion, wear, weld cracks
or deformations. Please ensure compatibility of bolt thread and tapped
hole. The Lifting Point RLP consists of several components: Bolt with locking
ring, house, bush and D-ring. See picture no 1.
The material construction, to which the lifting point will be attached,
should be of adequate strength to withstand forces during lifting without
deformation.
Minimum thread depth requirements (d refers to bolt diameter):
• 1 x d for steel (Yield limit >200MPa).
• 1.25 x d for cast iron (Yield limit >200MPa).
• 2.5 x d for aluminum alloy.
• For other metal alloys and other base materials, please consult your
Gunnebo Industries distributor.
• The tapped hole depth must take into account the thread length and
the internal thread run-out in accordance with SS 1403.
Adjusting the bolt length
If the bolt length needs to be adjusted, the instructions below must be
followed:
• The bolt shall be cut in a cold saw or lathe. Since the bolt has been
heat treated and hardened, it is of the utmost importance that the
temperature is kept as low as possible when cutting.
• After cutting, check the shape of the threads nearest the cut with an
appropriately sized die. Bevel if necessary (there must not be any
burrs).
Nut and washer
The nut and washer must be the original equipment supplied from
Gunnebo Industrier to ensure the correct mechanical properties
General assembly instructions:
The surface facing around the thread hole shall be flat (plane), clear of
paint and dirt, and smooth to ensure a perfect contact with the shoulder
surface of the lifting point.
