GROUNDSUPPORT
The Ground Support Tower is
manufactured with the purpose of
providing a lifting medium for the variety
of Thomas trusses ranging from the
smallest general purpose truss - through
to the largest Supertruss. The Tower
system is available as 30.5cm and 38cm.
The Towers provide a method of support
for truss grids in venues where flying by
other methods is impractical. Each Tower
is capable of lifting to maximum heights
of 12m (30.5cm tower) and 15m (38cm
tower) and capable of lifting 2 and 4
tonnes respectively (which must include
the self weight of the grid). The truss rig
is raised and lowered by means of chain
hoists, such as CM lodestar, which work
with a roller beam and double chain fall
to become an integral part of the system.
Towers can be used outside when used
with suitable restraints
