    Compact ergonomic self-propelled lifting machine
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a self-propelled lifting machine comprising a chassis with individual control of the traction on each of the traction wheels, the individual control of which is effected by means of a hand-operated electronic joystick, the lifting machine further comprising a crane arm or lifting device with the possibility of replacing it. the free end of this, via tool holder, mounted tool, said chassis, in addition to the pulling wheels, is provided with a number of rotatable support wheels for stable and tilt-free driving, of which a pair of wheels is mounted externally on the chassis under the lifting device at the end of the lifting machine which also the tool holder comprises such that the outermost end of the lifting device in the resting state extends beyond these rotatable support wheels and so that, when fully extended by and maximally loaded lifting device, the same support wheel can continue to be forced through the friction of the wheels against the ground and torque from the drive wheels, said lifting device the tool holder arrangement as well as the mounted tool can be manually operated or it can be controlled via a wired or wireless remote control where movements are then performed by a number of actuators, in addition the same lifting device tool holder and thus the mounted tool has a number of degrees of freedom which include lifting up and down with pivot point in the joint between the chassis and the lifting device, tilting of the tool holder with pivot points in the joint between the tool holder and lifting device, rotation with or counterclockwise of the tool holder and right / left bending movements of the tool holder ..
    Self-propelled lifting machines for maneuvering and handling plate-shaped elements such as glass, metal, wood etc. are now commonly used in construction and other industries.
    From i.a. US 5584646 A is known, inter alia, a self-propelled lifting machine comprising an undercarriage and a rotating "tower" on which is mounted a lifting device with means for holding, lifting and maneuvering plate-shaped building elements.
    In addition, there are also several examples of vehicles having individual control of the traction of the traction wheels, and where this traction is controlled via a joystick, e.g. For example, from US 20110206489 A1 a self-propelled pallet truck / stacker having a control means designed as a joystick is known, which is intended for both control of the device's moving movements and for controlling the hydraulics for the lifting movements. The stacker has individual traction control on the traction wheels and in addition it is also provided with support wheels that can be pushed out to increase stability under load. Common to these known lifting machines is that they are designed with the aim of facilitating the work of lifting and handling heavy and unmanageable elements.
    It is an object of this invention to provide a compact self-propelled ergonomic lifting machine which does not include pivots and or other side displacement devices which may contribute to instability but a machine capable of maneuvering (also laterally) by activating a joystick in it. desired direction whereby the positioning of the machine is increased with increased productivity and at the same time increased safety, in the workplace where the machine is used.
    A further purpose is to provide a compact lifting machine that can operate safely for a long time in even very limited space especially indoors, but also outdoors. At the same time, the lifting machine must be simple to fold and easy to transport, even in smaller vans.
    The object of the invention is met by a self-propelled lifting machine of the type set forth in the preamble of claim 1, which is characteristic of adding an extension function in the lifting device to the degrees of freedom of the lifting device.
    This makes it easier and safer to position the lifting machine and its tool holder with burden / item when working with the set-up of elements, as each operator can at any time maneuver the lifting machine easily and precisely around the workplace, regardless of the machine's load, even where the space is cramped, without tiring this unnecessarily physically with wrong postures.
    As stated in claim 2, characterized in that the joystick is located at the end of the lifting machine which is furthest away from the tool holder of the lifting device, whereby it is achieved that the operator can always have both machine, load and positioning position within the field of vision during the working process and thereby have the complete overview and the complete control over the work task which is a great advantage in terms of safety. Other suitable embodiments are set forth in claims 3 to 5
    As stated in claim 7, characterized in that the tool on the lifting device can be removed and placed in transport rails on the chassis, whereby the lifting machine, relatively simply, can be compactly packed for transport even in a smaller van.
    The chassis described below for a self-propelled lifting machine is based on known technology in which the mobility of the machine is achieved by applying the same principles in the driving machine as on an electric wheelchair, but with the great difference from the wheelchair that this machine also works excellently with a very large part of the weight transferred to the swivel front wheels, this gives construction minimal turning radius as well as optimal maneuverability, which increases productivity and safety, especially on relatively small and complex areas.
    The invention is explained below with reference to the drawings, in which:
    FIG. 1 shows the ergonomic compact self-propelled lifting machine in perspective, seen from the right side and inclined from behind and inclined from above.
    FIG. 2 shows the lifting machine seen from the left side, while
    FIG. 3 shows the self-propelled lifting machine packed and prepared for transport.
    The ergonomic and compact self-propelled lifting machine shown in Figure 1 comprises a chassis (1) supported by a plurality of wheels (6, 8 and 9) of which the two rear (6), in the preferred embodiment shown here, are the driving wheels and the remaining wheels (8 and 9) are rotatable support wheels which ensure a stable and tilt-free ride, of which the two support wheels (8) can also be swung out to the sides to further stabilize the lifting machine by the resulting increase in the track width. In addition, on the same chassis (1), a central upright is constructed at the rear center, around the lower part of which is made room for a variable number of counterweights (7), the upriver additionally forms a base for the lifting machine control means and also acts as a hinge point for a crane arm with a number of degrees of freedom such as lifting, extending, tilting, tilting or rotating, this crane arm is additionally provided at its free end with a tool holder (13) for holding and manipulating a replaceable tool (10), this tool holder (13) can be rotated and locked step by step. 30 degrees from 0 to +/- 90 degrees, which means, among other things, that the load-bearing tool, if necessary, can be swiveled on the side of the self-propelled lifting machine so that the lifting machine can load even narrow passages such as for example. doorways. The assembled lifting device (2), consisting of the aforementioned crane arm, the tool holder (13) and the interchangeable tool (10), is therefore an extremely flexible lifting tool capable of handling and positioning the load accurately and safely also in places where the space is urge. The lifting device (2) and the attached tool (10) are manually moved or controlled via a wired or wireless remote control (3) where the lifting device (2) movements are then performed using either manual movements, electric actuators, electric motors, gas or hydraulic cylinders.
    The chassis (1) of the self-propelled lifting machine is driven by two powerful motors, which are directly coupled to the drive wheels (6) whose traction and direction of rotation are individually controlled via an electronic joystick (5) which, in the preferred embodiment of the lifting machine, is based on the central upright and is placed at the back of this one so that the operator has a complete overview of the work situation. The support wheels (8, 9) mentioned above, in addition to the driving wheels, are forcibly guided through the friction of the wheels against the ground and torque of the drive wheels (6). The turning function is achieved by the two motors running at different speeds, forcing the chassis (1) to change direction. When the chassis (1) has to rotate about its own center axis, one motor incl. drive wheel (6) forward while the other motor incl. drive wheels (6) rotate back.
    The above mentioned lifting machine design, together with the joystick (5) is easy to operate and can be adjusted to the individual operator's physics with height adjustment and adjustability between right and left hand grips, allowing the lifting machine even with maximum load on the lifting device (2) and with the load placed in front of the The front support wheels (9) are easy to handle and can be maneuvered and turned so that the operator, with the ergonomically placed control means, can easily, safely, without stress and with a complete overview of the working situation, place the machine in the optimal position for positioning the load.
    As shown in FIG. 3, the relatively compact lifting machine can be relatively easily packed in a transport position where the tool (10) is removed from the tool holder (13) and located in the transport rails (12) on the machine chassis (1) and can easily be transported in even smaller vans.
    The intended compact ergonomic lifting machine is intended to be used within the industry as an alternative or supplement to other lifting and transport equipment.
    The self-propelled lifting device can be used in conjunction with many tools, in addition to vacuum yaws shown in the preferred embodiment shown in Figures 1-3. Can be mentioned, for example: magnetic yoke, lifting hook, pallet forks, lifting tongs etc.
