    BACKGROUND OF THE INVENTION , wherein the gear unit has a primary side connected to the hoisting motor and a secondary side connected to the rope roller, and wherein, when viewed vertically from the hoisting carriage, the rope roller is located between the hoisting motor and the load beam parallel to the load beam.
    Traditionally, in a hoisting trolley of the type described above, the hoisting machine is supported on the hoisting trolley between the end of the rope roller facing away from the gear. The torque caused by the use of the lifting mechanism is received at the second support point on the primary side of the lifting mechanism, whereby the support force decreases as the support distance increases.
    The provision of torque support in this way is one of the determining factors for the width of the hoisting carriage (carriage carriage body) or the track width of the hoisting carriage, which may become too large for certain applications of the hoisting carriage. Primary shoring point away kuormapalkista creating a situation in which the fulcrum is a natural number placed on the end of the load beam at the ends of the supporters, and thus -tuentapisteen place for the trolley track width. An alternative way = is to make a projection on the side of the load beam, whereby the structure of the load beam becomes multifaceted, bulky and heavy.
    o SUMMARY OF THE INVENTION Ek The object of the invention is to improve the support of a lifting mechanism so that the above-mentioned problems of N 30 can be solved. This object is achieved by the lifting carriage 2 of the invention, which is characterized in that the hoisting machine is supported on a three-pistetuennalla frame beam 3, wherein the first supporting point and the second support point of the secondary side are located next to the gear so that the first supporting point is above the frame member, and a second support points at a distance from the lower frame member,
    from the first support point, and wherein the third support point is formed from the support of the end of the rope roll away from the gear to the load beam at a lateral distance from the first and second support points.
    The first support point receives the directional forces of the radius of the support point, which arise from the masses, the resultant of the rope force and the support force of the moment caused by the resultant of the rope force. The mass of the hoist, hoist motor and rope roller, in turn, provides compression to the second support point. In addition, the second support point acts as the second support point of the torque produced by the rope force resultant.
    The torque support arrangement according to the invention, in which the second support point, i.e. the torque support, is also arranged on the secondary side of the hoisting machine, but at a sufficient distance from the first support point to the load beam, provides the necessary torque support. This removes the restrictions mentioned at the beginning, which are caused by the provision of torque support for end supporters.
    A preferred application for the solution according to the invention is a hoisting carriage, in which an active rope guide device is used for multilayer winding and guiding of the rope to the rope roll, whereby one or more lifting ropes are wound effectively on a short rope roll via several folding wheels. However, the use is not limited to such a hoist, but the invention can be applied to all hoists where the width or track width of the hoist is desired to be independent of the provision of the torque support required by the hoisting machine. The solution according to the invention thus makes it possible in particular to increase the width or track spacing of the lifting carriage.
    © The arrangement according to the invention also facilitates the installation of the lifting mechanism and does not increase the internal forces of the gear unit.
    Preferred embodiments of the invention are the subject of dependent claims.
    = 30 BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with a preferred embodiment = with reference to the accompanying drawing, in which © Fig. 1 shows a part of a lifting carriage in a perspective view from above; Fig. 2 shows a perspective view of the hoisting carriage shown in Fig. 1 from a downward slope, and
    Figures 3a and 3b show the arrangement of the pre-tensioning of the second support point. DETAILED DESCRIPTION OF THE INVENTION Referring to the figures of the drawing, there is shown a substantial part of a lifting carriage 1 related to the present invention. It comprises a lifting carriage body showing only the transverse load beam 2 of the lifting carriage 1. Other body parts not shown, related to the load beam 2 relevant to the invention.
    The hoisting carriage 1 shown in the figures further comprises a hoisting mechanism 3 supported on the hoisting carriage body 2 and comprising a rope roller 4 for at least one hoisting rope (not shown), a hoisting motor 5
    The gear 6 has a primary side connected to the hoisting motor 5 and a secondary side connected to the rope roller 4, the vertical view of the hoisting carriage 1 being located between the hoisting motor 5 and the load beam 2 parallel to the load beam 2.
    The essence of this invention is that the lifting gear 3 is supported on a three-pistetuennalla A, B, C frame beam 2, wherein the first supporting point A, and the second supporting point B are located next to the gear 6 of the secondary side so that the first supporting point A frame member, two upper and one supporting point B of the frame side member 2 lower at a distance from the first support point A, and wherein the third support point C is formed from the support of the end of the rope roll 4 away from the gear 6 to the load beam 2 at a lateral distance from the first and second support points A, B.
    At the first support point A, the movement of the gear flange 7 of the gear 6 = in the vertical, longitudinal and transverse directions is prevented, but rotation is allowed, i.e. in the XYZ coordinate systems shown in the figures, movements in the X, Y and Z directions are inhibited, = when rotations in these directions are free . At the second support point B, the movement of the gear 2 6 in the direction towards the load beam 2 is prevented, but the movement of the load E 30 in the longitudinal and vertical direction and rotation is allowed, i.e. in said coordinate systems the movement in the Y direction is prevented, but in the X and Z directions allowed, free in all directions of rotation. The support point B forms the torque support of the gear, whereby, depending on this support, the distance N of the resultant of the rope force causes compression or traction towards the load beam 2. At the third support point C, the vertical movement of the end of the rope roll 4 away from the gear 6 in the vertical direction and towards the load beam 2 is prevented, but movement in the longitudinal direction of the load beam 2 and rotation is allowed, i.e. only movements in Y and Z directions are prevented but free in X direction. being free. Gravitational force Fzja on the line between the support points SL The resultant of the support moments Mm = Fgx SLFg and Mr = Fr x SLF caused by gravity and rope force determines the magnitude and direction of the force (compressive or tensile force) on the support point B.
    Preferably, the lifting mechanism 3 comprises a vertical mounting flange 7 attached to the side of the gear 6, the first support point A comprising a first lug 8 at its top on the vertical side 2a of the load beam 2, the top of the mounting flange 7 being supported by holes 9 in the top of the mounting flange 7 and the first lug 8. with a longitudinal pin and ball joint 10 mounted through the load beam 2. The second support point B comprises a second lug 11 on the vertical side 2a of the load beam 2 with a vertical opening 12 into which the support projection 13 formed in the lower part of the mounting flange 7 extends.
    Of course, the above-mentioned mounting flange 7 can also be part of the housing of the gear unit 6. The third support point C comprises a third lug 14 on the vertical side 2a of the load beam 2 at the end of the rope roll 4 facing away from the gear 7, on which the end Xs of the axis X of the rope roll 4 is supported.
    Referring to Fig. 3a, the second lug 11 is preferably provided with a horizontal prestressing towards the vertical side 2a of the load beam 2. This converts the traction into compression at the support point B. In addition, a sliding surface 14 is provided between the vertical side 2a of the load beam 2 and the second lug 11, which may be arranged between the second lug 11 and the vertical side 2a of the load beam 2. The prestressing uses a resilient element 15 between the clamping surface of the lug 11 and the support projection 13, which is shown in Fig. 3a in a compressed state. The uncompressed state of the flexible element 15 © is shown in Figure 3b.
    D Alternatively, the above-mentioned mounting flange 7 may be part of the gearbox 6 N housing.
