The aim is to shorten assembly times and increase occupational safety. The task to lift and transport such loads in a predetermined Schraeglage is solved by a special load handling equipment. It consists of a traverse, which has at the ends transom, which are arranged asymmetrically. The crossbeams are slotted at the ends and provided with Arretierstuecken. Here, tie rods are mounted height and side adjustable. The tie rods of a crossbeam are connected at the bottom by Unterzuege. The load is clamped between the lower joists and the crossbeam with the crossbeams.

Description

The invention is explained in more detail in the following example, accompanying drawings show

ir 1: the load-carrying device in front view, and top view

ir 2: View A according to FIG. 1

ir 3: different load cross-sections with center and eccentric center of gravity in the stressed state of the load.

Traverse 1 is designed in box girder welded construction. It is provided in the middle part 6 with an opening and an additional ionizable hanger with two sockets of different sizes diameter, the design allows the inclusion of various single hooks of assembly cranes. The pins are equipped with handle and lock by a> e rotation after insertion.

two transverse bars 7 are arranged asymmetrically on the traverse 1. They are connected to the cross member 1 by a bund welded construction. Depending on the required width range of the loads to be transported srträger 7 are provided with on both sides different lengths, vertical continuous slots 4. In this case, the netic arrangement of the transverse beams 7 and the length of the slots 4 depend on the largest eccentric center of gravity of the loads to be isported. The width of the slots 4 is determined by the diameter of the tie rods 2.

four tie rods 2 are provided at the top with a trapezoidal thread and at the bottom with a fork. The ge of the trapezoidal thread is determined by the required height adjustment range of all loads to be transported. The ielbreite of the tie rods 2 is determined by the width of the beam 3. Fork and spindle part of the pull rod 2 are

jesteif welded together. .

Tie rods 2 are inserted through the slots 4 and set off via a nut with Axiairiilenkugellager and pressure plate the crossbar 7 from. The nut with trapezoidal thread is designed as a hand wheel 5 for bracing the load.

to store the handwheel 5 against rotation when clamping the load, the upper chords of the crossbars 7 in the areas of the strand 4 are provided with locking pieces 8. Their distances depend on the selected printing plate width of the handwheel 5. In this case I for a precise locking of the load-carrying means on the load smaller distances cheaper. The two beams 3 are formed in fil-welded construction and provided with holes for receiving the locking pins for connection to the forks of the rods 2. The length of the beams 3 is determined by the largest width of the loads to be transported. The number of holes in the beams 3 is determined in connection with the grid spacing of the locking pieces 8 on the crossbar 7 that is the required width range of the loads. Each Steckbölzen is in turn provided with handle and lock s falling out.

Dimensions of all-bearing elements of the claimed load-handling device are determined as a function of the heaviest living load, taking into account a mass force factor during lifting.

FIG. 3 schematically shows loads having rectangular cross sections of different dimensions in the state loaded with the load receiving means, showing different center of gravity positions.

Claims (3)

Invention claim: 1. load-carrying means for long parts with mostly rectangular cross section of different dimensions and changing center of gravity, which are transported in a predetermined angle by crane, consisting of a traverse with support elements, cross members, tie rods and beams, characterized in that the cross member (7) asymmetrically the crossmember (1) are arranged and have slots (4) for receiving the tie rods (2). 2. load-carrying means according to item 1, characterized in that on the cross members (7) in the region of the slots (4) locking pieces (8) are arranged. For this 3 pages drawings Field of application of the invention The invention relates to the striking and transporting of long parts with mostly rectangular cross section and with different center of gravity positions by means of a mounting crane. Characteristic of the known technical solutions For assembly or disassembly of long parts such. As crane or pipe bridges are commonly used in the art ropes for striking the loads. In crane transport of such box-type components, the slings are carried under the bridge. In this case, costly measures for edge protection are necessary and the rope wear is high. In order to avoid unwanted skewed parts, the position of the ropes must be changed several times. This work is time consuming and dangerous. Since the contact points of the load on the slings are lower than the center of gravity of the load, which is often eccentric by one-sided patch elements in both axes of the horizontal plane, it always comes back to tipping or tilting of the load about its longitudinal axis. This leads to disruptions of the work process, possibly even to damage and to threats to the operating staff. US Pat. No. 3,443,831 suggests that long parts, e.g. B. timber stack to clamp in the vicinity of the ends between crossbeams and beams and mitteis strike chains and transport. When the center of gravity is outside the longitudinal axis, however, the load always jams about its longitudinal axis because the center of gravity is set vertically below the crane hook. The use of chains does not prevent any occurring rocking. The change in the position of the crossbar is also time consuming, because they must be individually umgehängt, which several Kranspiele are necessary. Ziei the invention The aim of the invention is the assembly time for long parts, z. As for the placement of Krahbrücken on the crane rails or pipe bridges on the bearings of the carrier to reduce the expenses and to improve the safety. Explanation of the essence of the invention The technical problem which is solved by the invention It is an object of the invention to raise long parts with box-shaped cross-section and changing center of gravity in a predetermined by the assembly or disassembly skew by mounting crane, transport and sell, the position of the attachment points to the center of gravity of the load is arbitrarily variable and the center of gravity of the load lies as the contact points of the load on the load-handling device. Features of the invention The object is achieved by a load-carrying means, which consists of a traverse, each with a crossbar at the ends, four tie rods and two beams. The crossbeam is open in the middle to receive different sized crane hooks. The crossbars are asymmetrically attached to the ends of the crossbar. They are provided at their ends with vertical through openings. In each opening a drawbar is mounted height and side adjustable. The height adjustment is via a thread on the upper end of the drawbar and a nut, which is supported on the crossbar. At the lower end of the tie rods, the beams are attached. The load handler is placed on the load according to the desired angle. The tie rods are hung on the appropriate width and gravity of the load in the openings at the ends of the crossbars. Then the beams are fastened in the tie rods and the load is braced against the crossbar. If the desired inclination does not occur when lifting the load, the position of the load handling device on the load is corrected. This is followed by the lifting, transporting and settling of the parts themselves. With the claimed load handling device ensures that the loads to be transported raised in the skew due to the installation, transported and sold to prepared camp without it comes to unwanted inclinations, by rocking or overturning the load to damage or hazards to the assembly staff ,
