6.3.4 Mast climbing work platform with
two masts on ground frames
One drive unit must be adjusted
for "left" and the other for "right".
1. Check that the left-hand machine is
adjusted for "left" and the right-hand
machine for "right". See section 6.7.
2. Position the ground frames parallel to
the wall and with a separation to
allow for the required distance
between the masts.
3. Place the ground supports for both
ground frames.
4. Level the machine using the jacks.
Ensure that the mast is vertical in
both directions by checking with a
spirit level (with a length of at least 1
metre / 40 inch) placed against two
adjacent sides of the mast. Place
wooden packing under the machine
to provide optimum load spreading
and stability.
5. Check that the autolevel locking pins
for securing the parallel movement
and the lower striker plates are
mounted.
6. Assemble the platform components
sequentially on both sides of the drive
units until the desired length is
attained. The platform may not
exceed the maximum length.
7. Tighten the platform bolts until the
specified torque is applied.
8. Assemble the second ground frame
to the first by fixing the platform
elements together.
