Lift of the farm: how to execute on your own

The clamp is a pipe with an external diameter of 120 mm and wall thickness of 12 mm. The pipe passes through the holes left in the compressed and stretched belts, into which protective clips are inserted. The lower part of the pipe during a farm roller rotates around the bolt in brackets attached to a solid -tree bar. After the launched, the clamp supports the farm at the upper compressed belt. The lifting of a farm 38 m long is performed by two double taps with a carrying capacity of 35 tons each. The capture is made at four points using two traverse. Capture points, as can be seen in the figure, are distributed evenly. During construction, high -quality pipe rectangular electric welding pipes that can be ordered here. During the overwhelming, it is necessary to ensure that both taps be lifted with special thoroughness at the same pace and at the same speed. If, due to the not-so-accurate distribution of the load during the retrunch of any of the traverse, the ascent at two points of the capture occurs unevenly, it is leveled, loading the counterweight faster the rising traverse. Otherwise, the farm is overwhelmed. Ruttering and lifting small -sized lattice or double -breeding structures can be performed using one tap and one simple design traverse. The beam is captured by a closed cable passed through blocks that are attached to both ends of the traverse. Such methods of strapping with a cable are not allowed, in which it is possible to slide it on the surface of the element during the relaying. In the described case, the use of blocks excludes the possibility of such sliding.
