The invention relates to a mounted crane for mobile
equipment with a work platform equipment on the open end of
the mounted crane, which is connected with the derricking
jib.
A work platform with a catwalk positioned on a column
around the vertical column axis in such a way that it can be
swivelled is known from DE-OS 27 20 254. The column is
positioned in a shifting bearing so that it is axially
shiftable. The shifting bearing is positioned in a swivel
bearing around an obliquely oriented axis for the vertical
column axis such that it can be swivelled. The work
platform in addition has a mobile jib which is rotatable
about a vertical axis on the end of which the drag bearing
is attached. To this end the mobile jib is a pneumatic
crane. In addition, a mounting point for the end of the
crane cable is provided on the column to raise and lower the
column with the crane cable. The swivel bearing is
connected to the jib by means of separable coupling units.
The coupling units also have attached, coordinating
connection pieces on the swivel bearing and the jib, which
can be connected together with socket pins. The catwalk is
attached at the top as well as at the bottom ends of the
column. In addition, a driver is provided to swivel the
shifting bearing.

In DE-OS 30 11 945 a mounted device for a mobile crane
with a vertically adjustable, vertically swivelable jib
which is rotatable about a vertical axis is described. This
mounted device is recognizable by an L-shaped support which
has a fastening appliance on a post for fastening a
horizontal swiveling axis on the end of the jib and on the
open end of the other post. In addition a support arm
positioned on the swivel axis is provided which can be
swivelled by means of a hydraulic motor. The support arm is
connected with a work platform. In addition, the support
arm can be swivelled between two end positions, whereby it
is oriented in the end position approximately in parallel to
the free post and in the other end position is perpendicular
to this.
From DE-OS 39 11 677 a work and manipulation appliance
with a working mast made from multiple jibs which can be
swivelled on their ends against each other and therefore are
collapsible against and apart from each other is known. The
base jib is positioned on a rotary bearing pedestal situated
on a chassis for this purpose. Its end jib can be mounted
on its front end with equipment that can be swivelled about
an axis perpendicular to its longitudinal extension. For
this, the working device is additionally at least 180
rotatable opposite the end jib, about an axis parallel to
the longitudinal extension of the end jib.
In DE-OS 29 35 944 a telescopic jib positioned on a
pedestal and arranged opposite the pedestal such that it can
~ 21~31~3
be moved in a swiveling manner is provided. On the free end
a work platform is arranged in such a way that the work
platform is constantly aligned horizontally, independently
from the oblique position of the telescopic arm.
An exact positioning of construction pieces or elements
which are to be attached to the facade of a building
generally proves to be difficult because exact positioning
with the truck carrying the crane must be accomplished. It
normally does not suffice simply to drive approximately to
the assembly point with the truck, rather it is necessary to
undertake as exact a positioning as possible which is
difficult even for experienced truck drivers.
It is an object of the invention to provide a crane
which is independent of an outside energy supply and thus is
self-sufficient for energy purposes and with which it is
additionally possible to lift construction pieces in the
shape of bulky plates and long supports of frames and/or a
work platform and position them precisely without requiring
that this precise positioning be accomplished with a
construction or automatic crane or similar device; rather,
it is sufficient to bring the construction pieces and/or
work platform close to the assembly point with the
construction or automatic crane alone.
This problem is solved in the invention in that an
automatic vertically aligning leveling module is arranged on
the open end of the crane jib, that a rotary module is
provided behind the leveling module on the vehicle side,
~143153
with which the construction pieces connected to the rotary
module are to rotate about an axis which is always
vertically oriented by the leveling module, that a linear
module is provided behind the rotary module and that a work
platform, or equipment is arranged on the linear module.
In this way one provides a mounted crane of the sort
with which the person or persons located on the work
platform can bring the work platform to the desired position
without it being necessary that the operating person or
persons converse over a long distance with a person standing
on the ground far below. Through this, it is simultaneously
ensured that a positioning device on the work platform is
operated and manipulated directly from the work platform.
In a further embodiment of the invention, an energy
module, for example a hydraulic and/or electric and/or
pneumatic energy source, is provided for driving the mounted
crane from the work platform or on another construction
piece for the mounted crane. Through this, the mounted
crane is independent of any remote energy supply, so that it
can be set on such places and construction sites which are
not connected to an electrical supply network, for example.
Appropriately, the energy module can have additional
connections for supplying energy to the connectable
positioning device and the erecting tools. Through this the
positioning device and the erecting tools are independent
from the outside energy supply.
2 1 4 ~ 3
The horizontally and/or vertically working linear
module is advantageously perpendicularly oriented and
adjustable in height against the rotary module.
Suitably a telescopic linear module is positioned
behind the perpendicular rotary module on the vehicle side,
and can be swivelled around two parallel horizontal axes and
is developed as a telescopic mast.
The telescopic linear module can have a right-angled
horizontal rotary axis running toward the longitudinal axis
of the telescopic linear module on each end, which carries
the vertical orientation of the leveling module to the
module attached on the assembly side or the positioning
device or work platform over an arrangement for forced
synchronism.
Suitably the mounted crane is developed in such a way
that a work platform is arranged on the linear module which
can be rotated or adjusted vertically or horizontally
against the leveling module. Through this, all movements
necessary to the operation are possible.
Between the rotary module and the work platform or the
positioning device, a vertically oriented rotary module on
the assembly side is provided.
Preferably a work platform is provided on the open end
of the linear module. In a further aspect of the invention,
the crane can be developed in such a way that a positioning
device is provided on the work platform or on the acceptance
coupling of the rotary module on the assembly side or the
214~ 3
end of the linear module on the assembly side with which the
following movements can be accomplished:
a) lifting and lowering,
b) shifting from side to side, from left to right,
c) shifting longitudinally forwards and backwards,
d) tilting about a horizontal longitudinal axis above
to the left and the right,
e) turning about a vertical axis to the left and to
the right and
f) swiveling about a horizontal cross axis.
This makes the acceptance, movement, holding and release of
construction pieces possible.
Preferably a lifting module is situated on the vehicle
end of the positioning device that is to be connected with
the mounted crane or the work platform and is adjustable
against this by means of a lifting drive and which can be
fixed at a desired height. On the front of the lifting
module, a shifting module is positioned and which can be
shifted to both sides and stopped in a desired lateral
position by means of a shifting drive. A distancing module
is provided on the front of the shifting module and which
can be lengthened or shortened in the longitudinal direction
by means of a distancing drive and held in a desired
position. A swiveling module is movably positioned on the
front of the distancing module and can be swivelled and
stopped in the desired swivelled position by means of a
swiveling drive.
21~31~3
Between the shifting module and the distancing module,
a tilting module can also be provided that tilts in both
tilting directions by means of a tilting drive about a
tilting axis oriented in a plane parallel to the ground
plane and perpendicular to the longitudinal direction of the
attached device. Also between the distancing module and the
swiveling module a rotary module can be provided that
rotates in both rotary directions about a vertical rotation
axis running through the middle longitudinal axis of the
distancing module by means of a rotary drive.
Mechanical, electrical, hydraulic, pneumatic or
manually operable drives are suitable for the drives of the
individual modules.
In a further embodiment of the invention, a frame
solidly connected with the mobile work equipment is provided
on the connector of the mobile equipment and a frame on the
assembly side is provided on the vertical rotary module on
the work side. Both frames are swivelably connected to one
another across a horizontal swiveling axis and the open end
of the frame on the vehicle side and the free end of the
frame on the assembly side are driven by a thrusting piston
gear.
If desired the required rotational movement can result
from a rotary piston drive.
For simpler applications, the modules can be exchanged
or left out.

On the mast 10 of an automatic crane, which is not
illustrated in the drawing, a frame 14 on the vehicle side
is provided on its free end 11 with connection elements 12,
13, which is connected over swivel joint 15 with a frame 16
on the assembly side such that it can be swivelled. On the
upper end of the frame 14 on the vehicle side a cylinder 17
of a thrusting piston gear 18 serving as a level regulator
is connected in a joint 19, while the piston rod 20 of the
3 ~ ~ ~
thrusting piston gear 18 is flexibly connected in a joint 21
of the frame 16 on the assembly side.
On the frame 16 on the assembly side a rotary module 24
is provided by means of a coupling 22,23 that is rotatable
about the rotary axis 25.
On a coupling 26,27 of the rotary module a vertical
linear unit 28 is provided which can be moved forwards and
backwards in the direction of the double arrow 30 by means
of a motor 29. On the vertical module 28 a horizontal
linear unit 31 is arranged that can be moved forwards and
backwards in the direction of the double arrow 33 by means
of a motor 32.
On the outer end of the horizontal linear unit 31 a
coupling 34,35 is provided, on which a vertical rotary
module 36 is arranged which is rotatable about the rotary
axis 37. On the vertical rotary module 37 on the assembly
side a work platform 38 is provided on which the underside
of an energy module 39 is fixed that can consist, for
example, of an internal combustion engine as a driver for a
hydraulic, electrical or pneumatic energy source.
On the outer end of the work platform 38 a coupling
40,41 is provided on which a positioning device (not shown),
fork lift or other similar construction piece can be
attached.
The example illustrated in Figure 3 differentiates
significantly from the examples illustrated in Figures 1 and
2 in that there is a swiveling module 42 with horizontally
-- 10 --
21~3153
running swivel axis 46 on the vertical rotary module 24 on
the vehicle side, on which an arm 43 with several telescopic
positions 44 is arranged, on the end 45 of which a work
platform is provided which is connected with the rotary
module 24 on the vehicle side and with the leveling module
in such a way that it can be swivelled about an additional
swiveling axis 47 in vertical forced synchronism.
