6.5.2 Premounting the Lattice Supports
Each lattice support is fastened with four anchor bolts. Each anchor
bolt has three nuts and two washers. The support is adjusted using
the two lower nuts. The support is secured using the upper nut.
One washer each is placed between the support and the nut
immediately below and above it.
• Remove the upper nuts (2) and washers (3) from the anchor
bolts.
• Screw the lower anchor bolt nuts (2) down until they are just
above the foundation.
• Lubricate the anchor bolt threads as per L1.
• Fasten the lifting tackle (6) to the lattice support (1) using two
M16 eyebolts and two shackles. Use two holes located diagonally
from one another in the top rails for this purpose.
• Lift the lattice support and set it down on the four anchor bolts.
• Screw the upper washers (3) and nuts (2) on the anchor bolts
until finger-tight. The nuts will be adjusted later during the
alignment operations.
• Remove the lifting tackle (6).
• Using a level, align the top of the lattice support horizontally in
both directions. Adjust the anchor bolt nuts to correct any
misalignment. Always make adjustments via both supports in
order to prevent deformation of the base frame.
• Tighten the anchor bolt nuts to a final torque of 250 Nm.
