Basket for shrinkage jobs resolves the technical problem of nonutilization of crane or hoist while it is being moved from one place to the place of shrinkage. It consists of bucket (1), platform (2), coil (3), winch (4), yoke (5 and 5a), platform (6), wheels (7). The bucket is pushed to the place of shrinkage, by means of a yoke (5,5a), and is attached to the construction, bucket (1) is lowered by means of winch (4), coil (3) untill the end, platform is being taken out on the side where shrinkage is being performed. After the completion of shrinkage jobs, platform 2 is drawn in bucket (1), by means of coil (3) and winch (4) elevated to a top position while a yoke is released and a bucket is pushed to the next position. |
