360° rotatable lifting point. The load ring is loadable in a range of 130° and can be positioned at any required angle due to its replaceable and patented spring. Likewise interchangeable is the hexagon-special screw from grade 10.9 material, which is sesecured against loss. The screw is 100% crack detection tested as well as covered with a chromate VI-free protection against corrosion, and marked with the load capacity and thread size.
pewag winner profilift alpha is able to withstand a 4-fold safety against break in all directions. Each lifting point is marked with an individual serial number that allows product traceability. pewag winner profilift alpha is available with metric or UNC-thread, whereas the lifting points with metric thread are also obtainable with customized thread lengths. The table with the working load limit depending on the type of application as lifting gear, number of legs and angle of inclination is a part of the user manual and packed together with each lifting point.
Load capacity acc. to the inspection certificate respectively table of
WLL in the mentioned directions of pull – see picture 1.
Non permissible usage
Make sure when choosing the assembly that improper load can
not arise e.g. if:
• The direction of pull is obstructed
• Direction of pull is not in the foreseen area (see picture 2)
• Load ring rests against edges or load (picture 3)
The load ring must be placed in the direction of pull before loading
– do not turn under load. For more details please have a look into
our user manual.
To calculate the necessary thread length (L):
L= H + S + K + X
H = Material height
S = Thickness of the washer
K = Height of the nut (depending on the thread size of the screw)
X = Excess length of the screw (twofold pitch of the screw)
L max. = n max.
In case of requesting a lifting point with a special thread length,
please mention the requested thread length “L”.
