AVANTI Service Lift for Wind Turbines
The components subjected to possible movement
inside the tower may include, but are not limited to,
dampers, wire ropes, cables, doors, hatches, etc. The
service lift needs a gap of 500mm below the lowest
landing area to accommodate the bottom buffers and
power cable.
9.1.3 Tower support brackets
The ladder rack is attached to the tower structure at a
distance of max 3000 mm. The tower support
brackets must be so designed that the ladder rack
anchorages can be mounted. The connection
between the tower support brackets and the ladder
rack anchorages is done with M12 bolts A2-70 tighten
with a torque of 50 N·m in the tower factory but with a
torque of 12 N·m on site once the tower has been
erected and before the cabin is going up. Reaction
forces on connection bolts must be considered in the
design of the tower brackets. This information may
vary with the installation characteristics. Contact
AVANTI to get the information.
