AIRPES' SOLUTIONS
Nacelle lifting beam
This tool consists of a main beam of a circular section of steel tube (1) with two trunnions (2) attached to each side. Additionally, there is a beam attached perpendicular to the main beam whose function is to help guide the tool during hoisting maneuvers.
The hoisting is done with a synthetic set of slings (4) that connect both the tool and the nacelle AD8. Both main beam and trunnions that are attached to it, are designed to accept aluminum wedges (figure 2) that allow adjusting the tool’s longitudinal and transverse angle.
Additionally, there are two rear supports (5) with sliding pins which allow fast hooking and release of the slings with the rear part of the nacelle AD8.
RESULTS
The reason behind this tool's design
The tool was designed for the full nacelle’s lifting (once the transmission tree is installed) in the 600t. ADWEN 8 MW generators.
