GRAVITY GOODS ROPEWAY
7 Execution and
Installation
7.1 Layout
Before laying out the ropeway site,
clearance should be done as a part
of any site preparation. However, it is
already indicated in earlier chapters
that the ropeway alignment should be
chosen in such a way that there is no
or minimum damage to the existing
ecology which includes clearing off
the trees, rocks and soil.
For layout, set the theodolite at
permanent peg point of either upper
station (A) or bottom station (B). Then
sight another permanent peg at another
station and set zero. Then transit the
theodolite and locate a point well
beyond the estimated location of outer
wall of the anchorage block and fix a
peg firmly. Now, rotate the theodolite
90 degrees in a horizontal plane, and
locate another point at few metres
distance from the side wall of the shed
and secure a peg. Then again, transit
the theodolite to find a point few
metres distance from the outer wall
of the shed on the other side and fix
another peg after which the horizontal
and lateral reference lines perfectly
