Fabrication
Specifications |
|
Fabrication is
carried out at our
Brakpan plant making
extensive use of CNC
machines for the
manufacture of tower
parts.
All towers designed
and manufactured
according to South
African Bureau of
Standards
specifications
SABS763, SABS 0162,
SABS 0160 and the
respective ISO,
DIN-, and IEC
specifications and
corresponds to the
requirements of the
job safety
regulations.
All our products are
subject to internal
quality procedures
to ensure quality
and reliability of
all parts.
Tower parts are not
painted during
manufacturing, but
paint can be packed
and shipped as an
option. |

Lattice Towers -
Standard Models |
|
Three and four
legged angular
lattice towers,
complete with cat
ladders, cable
ladders, internal
working and resting
platforms with
safety rails,
aircraft warning
lights, antenna
brackets, down
conductor,
foundation holding
down bolts and
template.
Three legged
towers:
Heights between 20m
and 70m, antenna
loading between 12 -
25m². Wind speed
typically 40m/s.
Four legged towers:
Heights between 36m
and 100m, antenna
loading between 17 -
56m². Wind speed
typically 40m/s.
Full tower and
foundation designs
provided with towers
in PDF format. A
General Assembly
drawing issued with
each tower shipped.
Additional designs
available with
different wind
speeds and antenna
loading criteria. |
