STEIGER ® T 700 HF
This development fulfils the market
requirement for a compact machine
of 70 m with a high lateral outreach
for the confined working space.
Through the new long triple upper
boom, the Up&Over outreach is
increased by further 3.5 m in comparison
to the T 650 HF. In transport
position, the machine is again very
compact.
Due to the 1.7 m higher articulation
point and the now 24.6 m long upper
boom, operations can be carried
out in narrow house canyons, e.g.
at the rear of buildings which were
previously very difficult to achieve
in this height class. Together with
the highly stable base frame, the extremely
robust construction made of
high-tech steel in polygonal technology
authorises a position inclination
of up to 2°.
The lower boom enables an angle
of elevation of 83°, so that the machine
can be positioned even closer
to the building and the outreach be
used even more efficiently.
The T 700 HF can be mounted on
different carrier chassis and be registered
with a GVWR between 32 and
36 tons. Due to its overall length of
only 11.99 m, neither an exemption
according to § 70 StVO (German
road traffic regulations) nor a driving
licence according to § 29 StVO
(German road traffic regulations) are
necessary in Germany. This allows
maximum operational flexibility - the
STEIGER ® T 700 HF is always ready
for use.
The proven Highflex functions of the
RUTHMANN’s HF series also make
the T 700 HF an all-rounder for all
imaginable situations. The working
basket can be rotated by 440°.
Working behind obstacles such as
pipelines or roof structures is optimally
feasible (up, over & back). The
2 m long Highflex-RÜSSEL ® can be
rotated by 220° – still more flexibility
for „under and up” works with
upright working basket as well as
for „up, over and back” works with
lowered Highflex-RÜSSEL ® .
Such as the complete HEIGHTperformance
series, the new STEIGER ®
T 700 HF can additionally be used
for underfloor works. Thanks to
the movable Highflex-RÜSSEL ® , it
is ideal for bridge inspections up to
17 meters below zero. It achieves 5
meter more underfloor outreach as
comparable machines.
The powerful Highflex working
basket of the STEIGER ® T 700 HF
carries up to 600 kg and can be
extended up to a maximum size of
3.82 x 0.97 m – remaining it to be
the largest working basket of the
market. All Highflex positions of the
STEIGER ® T 700 HF are also possible
with the extended working basket
and offer thus optimum space for
an assembly team, for example.
The approved HighFlex functions of the HF series are also on
board of the RUTHMANN-STEIGER ® T 700 HF.
The working basket can be rotated by 440° and in combination with the
movable Highflex-RÜSSEL ® , works behind and under pipelines are possible.
