3.1 Lifting tools
The permissible capacities of the engine crane, lifting tools, ropes, chains, lifting eye bolts, etc.
must always correspond with the weights of the parts to be lifted.
NOTE: The admissible lifting (max. loading) capacity in kg corresponds to the WLL = Working
Load Limit.
For fitting and removal of engine components or their transportation, only the tools which are in
perfect condition and intended for this purpose may be used. Ropes which have begun tearing
or otherwise are defective and tools which are damaged have to be exchanged.
For safe and proper handling of crane, suspension tools or transport of loads we recommend to
proceed as follows for safety reasons:
•
Determination of the weight of load
•
Determination of the suspension centres and weight distribution
•
Choice of attachment elements
•
Attaching and disconnecting.
CAUTION
If tools are combined (for example beams with shackles, RUD-eye bolts or RUD-swivel
lugs and ropes, etc.), it is always the weakest element which determines the maximum
lifting capacity.
3.1.1 Wire rope slings
The lifting capacity of the wire rope slings is listed under their tool number in the tools list.
3.1.2 Span-sets (round slings)
Span-sets have the advantage of easy and simple handling. The code and the color normally
indicate the maximum admissible total load. Loops and knots in the span-sets reduce their lifting
capacity by one third.
3.1.3 Eye bolts and eye nuts
Only those eye bolts and eye nuts may be used which are in accordance with DIN 580 &
582:2003−08 or which fulfil or exceed these values, including the safety factor.
All calculations for components and tools where eye bolts and eye nuts are used are laid out
accordingly and based on the mentioned standards.
