Mobile walking excavators
Top performance. Heavy duty technology.
Superior economic efficiency. Premium comfort.
For more than 40 years, KAISER has been standing for
in the development of mobile walking excavators
What Josef Kaiser had started in 1965 with the develop-
ment and production of the first walking excavator –
the so-called MUK – KAISER as the technological leader
has kept until now. Those who have closely followed the
mobile walking excavator industry in the past decades
will know our milestones: KAISER X4, TurboMobil,
TurboStar and KAISER S-Series. They had all been
the performance standards of their time and were
models for the entire industry.
What's top performance for us:
• Efficient power
• Sensitive hydraulics
• Optimum stability
• Heavy duty steel construction
Customer satisfaction and our customer's
economic success are a central focus of our
Our international experience of many years provides
us with a thorough understanding of our customers'
environment. In a cooperation based on mutual trust,
we are developing application-oriented solutions
which will provide you with crucial competitive

optimum stability, heavy duty design and construction –
those are typical KAISER characteristics
Optimum stability. The most extreme conditions bring out
the best of KAISER mobile walking excavators in terms of
engineering and performance. Their operational weight
is considerably lower than that of standard excavators
in the same power class; that's why KAISER excavators
move absolutely sure-footed even in extreme terrain.
Their heavy duty booms are impressive with enormous
reaches and excellent lifting capacity which can really be utilized
because of the excavators' great stability.
You can choose among different variants – each adjusted to its
primary field of application: designed for maximum climbing
properties or the most versatile mobility, with 4x4 models as
multi-functional carrier equipment.
realized for flexible applications
in the most difficult terrain
Sensitive hydraulic system. Head start through
power and engineering – KAISER's motto for
setting new standards in the segment of mobile
walking excavators. KAISER's development
concept relies on proven hydraulics components
which are convincing in sensitivity, thus enabling
fast, controllable movements.
Efficient engine power. The latest diesel engine
generation excels with lower emissions and the out-
standing torque available even at low rpm’s. All
KAISER products are also available, of course, with
environmentally friendly particle filters.
Modern fan management. Electronic fan
management provides for optimum operation
temperature at any time; it will lower fuel con-
sumption and keep the noise level at a minimum.
KAISER's fine tuning of diesel engine, hydraulics
and cooling system significantly lowers diesel
consumption and exhaust emissions. Its perfor-
mance values still remain the industry's reference

Performance comparison of mobile
walking excavators with other construction
because work and adoption should be worth it.
Economic efficiency is manifest not only in top
performance and low fuel consumption but also in all
other factors which are important for performance and
• Operator training
• After-sales service
• Operation period of the machine
• Resale value
• Excellent workmanship
KAISER mobile walking excavators are manufactured
according to the highest quality standards.
• Welding procedure EN* 24063 - 135 MAG*
• Strength and bending analyses by means of
FEM* calculations of the steel construction
• Multiple-body simulations of dynamic loads
• Many years of practical experience
For KAISER, quality is not only limited to the products
but applies comprehensively – especially in contact with
customers: "Whatever we'll do, we'll do it right."
Our comprehensive spare parts warehouse is excellently stocked
so that we are able to respond fast to virtually any demand. Its
high percentage of own manufacture allows KAISER great flexibi-
lity in spare parts availability.

Premium comfort –
because you should feel well
in your job
Your health and your well-being are important to
us; KAISER therefore cooperates closely with uni-
versities and institutes on the subjects of noise,
vibration, temperature and ergonomics.
Clearly arranged cabin. The comfortable cabin
with a clear all-around view is appealing with its wide
entrance, its spacious inside, and the ergonomic
adjustability of its operating elements. Hydraulic
bearings and hermetic insulation achieve lowest vibration
and noise rates. Serial equipment are an air-cushioned comfort
seat with a high backrest and many adjustment features, sun
blinds and, a hydraulic cabin tilt device. Optional equipment with
air conditioning and stationary heating provide for comfortable
working conditions in summer, as well as in winter.
Tested safety. The modern KAISER safety cabin has been tested
according to DIN ISO 3471 and DIN 24090 ROPS* and FOPS* and
provides maximum safety at work.
Ergonomic control. KAISER Futura ® joysticks allow very
sensitive movements and ensure non-tiring and efficient work.
All functions are directly performed via the joystick and the
three ergonomically arranged foot pedals.

The specific ergonomic
properties were optimized
in cooperation with the EU
project "Eurocabin project".
