with the growing number of transport
operations that cannot be handled with
conventional tow tractors.”
The power packs on the PST modules
can be operated via remote control using
a joystick. Loads weighing thousands of
tonnes can be moved in this manner and
rotated through 360 degrees if required,
the manufacturer adds. Due to the wide
range of environments that SPMTs are
required to work in, the PST modules are
designed to work at temperatures ranging
from below minus 25 degrees to more than
60 degrees Celsius.
The PST power packs are available
in different sizes with rated outputs
from 155 to 360 kW. “In addition, the
Goldhofer PST/SL-E modules are fitted
with electronic multiway steering with a
steering angle of +/- 135 degrees, with each
axle individually controlled by a sensor
and a stepless hydraulic worm gear drive,”
the manufacturer adds. Choices of steering
modes are available with the modules,
including normal, transversal (90 degrees),
diagonal and carousel.
Popularity of SPMTs is such that
manufacturers have been designing
trailer modules that can be switched from
normal pendular axles to self propelled
axles. In the last year Faymonville, for
example, introduced the third generation
of APMC trailers, where it is possible for
users to switch the hydraulic drive on and
off, so customers can use the axles in self
propelled mode or as normal pendular
axles (up to 80 km/h).
The Powermax G-SL-6 APMC 12x6
is one of the more popular Faymonville
models, a company spokesperson explains,
“The Russian transport company Beluga,
for example, was one of the very first
customers to purchase the module range.
During one of their projects, a container
was being transported in a low loader
combination with integrated APMC. At the
unloading point, due to reasons of space,
the low loader could only be moved to the
assembly in self propelled mode. To do so,
the tractor units were simply uncoupled
and the Powermax was used to move
the load.”
“Another advantage is certainly the fact
that in the G-modules we offer two more
models, specifically: MT (lighter) and UT
(lighter and lower),” adds sales manager
Arnold Luxen, “In contrast to this, only
a single line had been available in the
S-series until now.”
Future designs
Due to the need to operate on a range of
different work sites changes for SPMT
includes changes to the allowed bending
