  1 to 6, reference numeral 1 denotes a base on which truck wheels are placed. On the base 1, two reinforcing members 2 are provided so as to protrude at an interval in a direction orthogonal to the wheels of the truck. The wheel is placed on the base 1 between the reinforcing members 2 (see FIG. 6). The reinforcing member 2 has a function of stopping the vehicle in addition to the reinforcing function of the base 1. When the truck wheels are placed on the base 1, the base 1 is fixed by the weight of the truck, so that the post does not fall down even if a load is applied to the post to be described later.

  Reference numeral 3 denotes a support column that is vertically mounted on the base 1 via a fixing member 4. The strut 3 has a length higher than that of the truck bed, and a master rope attachment ring 5 is attached to the upper part. In this example, the support column 3 is a single object, but may be extendable and contractible by a sheath structure. When it can be expanded and contracted, it can be fixed by pinning or the like at a predetermined height. The lower part of the support | pillar 3 is inserted in the fixing member 4, and is attached to the base 1 so that attachment or detachment is possible. If the lower part of the column 3 and the fixing member 4 are bolted, the column 3 can be fixed to the base 1 more firmly. By attaching the support column 3 to the base 1 in a detachable manner, the parent rope tensioner can be easily transported and stored.

  According to the master rope tensioning device for trucks of the present invention configured as described above, the master rope can be stretched as follows.

  As shown in FIG. 6, after the lower part of the column 3 is inserted into the fixing member 4 of the base 1 and the column 3 is attached to the base 1, the rear wheel 7 of the track 6 is mounted on the base between the reinforcing members 2. Put it on 1. In this case, a gap is formed between the rear wheel 7 and the support column 3. Since the base 3 is fixed by the weight of the track 6, the support 3 does not fall down even if a load is applied to the support 3.

  In this way, when the support 3 is installed, the master rope 10 is stretched between the master rope attachment ring 5 of the support pillar 3 and the torii part 9 of the loading platform of the truck 6. In this way, the master rope 10 can be stretched over the loading platform of the truck 6.

  Then, when carrying out the work of unloading the load, the operator's lifeline (not shown) is locked to the master rope 10.

  The place where the master rope 10 is stretched is not limited to the above place, and for example, the master rope tensioner for trucks according to the present invention is installed at two places on the front wheel 11 and the rear wheel 7 of the truck 6, It may be stretched out.

  As described above, according to the present invention, the column 3 can be fixed by the weight of the track 6 by placing the wheels of the track 6 on the base 1 to which the column 3 is attached. No special member is required for fixing. As a result, the column 3 can be installed easily and in a short time.
