Definitions

• the invention relates to a loading harness with the features of the preamble of the claim.
• Loading harnesses of this type are generally equipped with telescopic parts in order to be able to load transport units (transport means) of different sizes.
• these spreaders Because of the requirement for positioning accuracy, for example when loading transport containers, hereinafter referred to as containers, these spreaders must be designed in such a way that rocking movements during the loading process are kept as small as possible. Free moving joints are therefore to be avoided and solid designs of the lifting, rotating and spreading drive units are required.
• Such gripping bags are also provided on the semitrailers of trucks in order to be able to load these semitrailers, for example on railway wagons.
• the gripping pockets are located more in the upper area of the semitrailer, e.g. 1.5 m above the tire footprint.
• the spreader has the following two extreme positions:
• the maximum position of the crossbar of the spreader is usually reached when gripping a semitrailer.
• the lower ends of the swiveled-down gripper arms must be approximately 1.5 m above the reference level, ie the wheel contact area of the semitrailer, since the gripper pockets, as mentioned, are at approximately 1.5 height.
• These gripping arms have a very considerable length, since between their gripping claws and the crossbeam of the spreader a considerable clear height must be available in order to ensure that the to be able to load the largest swap body.
• the largest swap bodies currently known, so-called jumbo containers require, for example, a clear height of 3.6 m.
• twistlocks attached to the crossbeam are therefore 5.1 m above the reference level when loading a semitrailer, ie 2.67 above the lowest position (when gripping an 8ft container). Due to the necessarily rigid load guidance already mentioned above, this considerable stroke travel of the spreader leads to considerable demands on the rigidity of the lifting mechanism and on the executives to be deployed during loading.
• the object of the invention is to reduce the requirements for the lifting device.
• FIG. 1 shows a spreader in a longitudinal side view, the gripping arms for swap bodies being pivoted up and the carrying arms for container loading being pivoted down into the working position in the left half of the picture, while the gripping arms in for the sake of clarity are at the right end of the spreader in the drawing their gripping position is pivoted down and the support arms are pivoted up into their non-use position;
• FIG. 4 shows the same spreader, again in front view, with the support arms swung down and the gripping arms swung up in the gripping position for loading a container.
• the loading equipment which is generally designated 10 and can be lifted and lowered at least by means of transport, which is not shown in the drawing, has a frame-shaped traverse 7 with telescopic front ends.
• support arms 9 are designed in the manner of a housing a horizontal axis 9 'pivotally attached in pairs.
• twistlock gripping devices 3 At the free ends of the support arms 9 there are twistlock gripping devices 3 which are arranged on the end face and in the hanging support arm position with their axis of rotation extending approximately vertically.
• the length H of the support arms 9 plus the twist locks 3 measured from the lower edge of the frame UKR is 3 for the current container and swap body sizes expediently about 1.26 m.
• Gripping arms 5 can be pivoted in pairs at a point above the crossbar 7 about axes 5 'extending approximately horizontally and parallel to the axes 9' between the non-use position and the gripping position.
• the gripping arms are equipped with conventional gripping claws 8 for the form-fitting, usually lockable gripping of swap bodies and semi-trailers.
• the swap bodies or semitrailers have corresponding gripping pockets 6.
• the gripping arms 5 can be pivoted laterally by means of piston / cylinder devices 11 about approximately horizontal axes 12 approximately perpendicular to the pivoting plane about the axis 5 '.
• the twistlocks 3 engage in known corner fittings 4 in the uppermost level of the container 1 during loading.
• the reference plane relevant to the stroke position of the spreader during loading is denoted by R.
• the mounting points for the gripper arms 5 arranged in pairs are fastened directly to the rigid, non-expandable central part 7 of the spreader.
• a distance-variable fastening also falls under the solution according to the invention.
• the loading harnesses according to the invention can also be set up in such a way that they can be used to load both a single means of transport and several means of transport positioned next to one another.
• This possibility is known per se, e.g. for loading two 20ft containers next to each other.
• additional support arms with twist locks which are also height-adjustable with respect to the crossbar, would have to be provided for a loading harness configured in this way.
