    BACKGROUND OF THE INVENTION The invention relates to work platform arrangements. The work platform arrangement is a lifting device for lifting the worker and the necessary objects such as the lamp to be installed and the necessary installation tools, which is equipped with a work platform such as a work platform.
    Conventional work platform arrangements, i.e. separate lifting devices, such as scissor lifts, which are movable on the ground or on the floor, for example on wheels, are known, but their lifting height is limited and they are unstable when lifting the work platform high.
    In connection with lifting devices without a work platform, i.e. in connection with the transport of heavy objects such as pipes or metal castings in a factory, it is known to use a bridge crane mounted between opposite parallel walls of the factory. a supporting winch underneath, i.e. a lift operating in the up / down direction, on which the load, i.e. the object to be moved, hangs. However, for occupational safety reasons, it is neither safe nor even permissible for the bridge crane's transverse transfer beam to be used as the employee's work platform.
    CN203820319 discloses a combination device of two different types of devices, but it is also not possible to provide an upward dimension, especially with a good level of occupational safety.
    Brief description of the invention The object of the invention is thus to develop a work platform arrangement, so that the above-mentioned problems can be solved. The object of the invention is achieved by N work platform arrangements, which are characterized by what is stated in the independent claim. Preferred embodiments of the invention are the subject of such claims. = The invention is based on the integration of a work platform hoist onto a 3 30 - overhead crane. © The invention has the advantage of a good reach for high-altitude installation sites, 3 good occupational safety and the possibility of utilizing bridge cranes already in use and of diversifying the possibilities of use by means of a work platform hoist.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with preferred embodiments with reference to the accompanying drawings, in which: Figure 1 shows a schematic diagram of a work platform arrangement on a Fig. 4 is a schematic plan view of several transmission beams comprised by different bridge cranes on common guide beams.
    DETAILED DESCRIPTION OF THE INVENTION A working platform arrangement 100 is shown in the figures, comprising a working platform 102 for an employee 104.
    Referring to Fig. 3, the work platform arrangement further comprises a control system C and a transfer arrangement TRB, TRC controlled by it for changing the position of the work platform 102.
    The control system C is implemented, for example, with a programmable processor.
    In the embodiment shown in Figure 1, the transfer arrangement TRC is a cylindrical lift.
    In the embodiment according to Figure 2, the transfer arrangement TRB is a hydraulic boom lift TRB, alternatively the transfer arrangement may be a scissor lift (not shown). The work platform arrangement 100 comprises a support structure 106 which support structure 106 is for supporting the work platform 102 and its transfer arrangement TRB, TRC above the bridge crane 200 on the bridge crane 200.
    The bridge crane 200 comprises a D transfer beam 202 to which the support structure 106 is supported / attached.
    The support structure 106 may be, for example, a base or other support with which the work platform arrangement 100 is lowered, i.e. the transfer arrangement (e.g. boom lift, scissor lift, cylindrical lift N) TRB, TRC supported at the lower end 106 may be on top of the transfer beam 202 as in the figures or on the <+ side or below, i.e. it is essential that by means of the support structure 106 the transfer arrangement TRB, 3 TRC is in the area above the transfer beam.
    S In the example of Figs.
    In Fig. 3, the control unit C is connected to control the actuator 106A, thus providing a transverse horizontal movement according to the arrow BZ on the work platform 102 (and on the supporting transport arrangement TRB, TRC attached to the support structure 106). The bridge crane 200, on which the work platform arrangement 100 is mounted / fixed via the support structure TRB, TRC, comprises a transverse transfer beam 202 extending in the direction between the walls W1, W2 of the factory or other building and guide beams 204, 206 fixed to the walls W1, W2. the transverse transfer beam 202 of the bridge crane 200 is movable by an actuator 208. The movement of the transfer beam 202 comprised by the bridge crane 200 is provided by an actuator 208 such as an electric motor.
    In Fig. 3, the control unit C is connected to control the actuator 208 moving that transfer beam 202 if it is desired that the worker 104 on the work platform 102 can move the work platform by moving the transfer bar (toward or away from the viewer).
    The direction of movement of the transverse transfer beam 202 is shown in Figures 1-2 either toward or away from the viewer.
    Since the work platform arrangement 100 rests on a transfer beam 202 belonging to the bridge crane, one direction of movement of the work platform arrangement 100 is the same as that of the transfer beam 202, i.e. in Figures 1-2, either towards the viewer or away from the viewer.
    Reference numeral 210 denotes a winch or other actuator comprising a bridge crane 200 by means of or through which a lifting movement according to arrow A1 and a transverse movement according to arrow A2 is provided, which is a movement in the direction of the transverse transfer beam 202.
    For example, the winch 210 is electrically operated, i.e. vertical movement is provided by a winch actuator such as electric motor 210A, and transverse movement in the direction of arrow A3 is provided by an actuator such as electric motor o 210B which displaces the winch (and thus for the horizontal movement of the winch N 210 (and the load).
    According to one aspect of the invention, the transfer arrangement TRB, TRC for changing the position of the work platform 102 is arranged to change at least the height position of the work platform 102 above the bridge crane 200 relative to the bridge crane.
    In addition, the control system = C comprising the work platform arrangement thus comprises a control part arranged to control the movement of the bridge crane, i.e. to practically control the movement of the transfer beam 202 of the bridge crane 200.
    The control system C comprising the work platform arrangement 100, for example the control part CP comprising it for controlling the movement of the bridge crane, is arranged to prevent the movement of the bridge crane, i.e. to prevent the movement / movement of the transfer beam. This prevents the overhead crane from being operated by the overhead crane's own normal operating devices (for example, a remote control with push buttons hanging at the end of the cable or a control unit in the control room). In practice, therefore, a bridge crane is prevented from being used by anyone other than those on the work platform.
    Referring to Figures 4 and 3, in one embodiment, the control system C, for example the control part CP comprising it, is arranged to further prevent the movement of one or more adjacent transfer beams 302, 402.
    This is necessary in factory halls or other premises where several bridge cranes are in succession, i.e. several successive or beams 202, 302, 402 are adjacent to each other on the same guide beams 204, 206. In connection with the above, Figure 3 shows a motor or other an actuator 308 which is an actuator for moving the second bridge crane / transfer beam 302 of Fig. 4.
    The control system C and the control part CP included therein may belong to or at least communicate with the user interface UI shown in Figures 1-2, which is connected to the work platform 102.
    In one embodiment, the control portion CP of the control system C included in the work platform arrangement 100 for controlling the movement of the bridge crane is arranged to enable the movement of the bridge crane. This feature is especially needed when a person on the work platform 102 is desired to be able to move the work platform in one or two horizontal directions. Such cases are the following two: In the first case, the control part CP of the control system C comprised by the work platform arrangement o 100 for controlling the movement of the overhead crane is arranged to control the movement of the overhead crane (transfer N bar 202). with the movement. Thus, that movement N 30 is in Figures 1-2 either towards the viewer or away from the viewer. In this case, it is a matter of E that, according to the figures, the control unit C and / or the control part CP therein is connected to control an actuator 208, such as an electric motor, for moving the transmission beam 202 belonging to the bridge crane 200.
    2 In the second case, the control system C comprised of the work platform arrangement 100 N 35 is arranged to control the horizontal movement of the work platform arrangement provided with the work platform 102 relative to the bridge crane. In this case, the control unit C and / or the control part CP therein are connected to control an actuator 106A arranged to move the work platform arrangement 100 on the transfer beam 202 comprised by the bridge crane 200 in the direction of the transfer beam 202.
    It is so that the horizontal direction of movement of the work platform arrangement 100 with the work platform 102 (arrow B2) relative to the overhead crane is substantially perpendicular to the horizontal direction of movement of the work platform arrangement with the work platform 102 (towards the viewer or away from the viewer).
    It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above but may vary within the scope of the claims. o O OF OF OF OF
