However, most constructions using the above described rides require a long construction period, and thus many rides are left in the work place for a long time. That is, when the leader 4 is supported and left for a long time by the backstay 3 described above, the weight of the above-mentioned working apparatus (about 12 to 25 tons) and the weight of the above-described leader 4 (15 tons) Load) is applied to the backstage cylinder 2 described above. For this reason, the above-mentioned backstage cylinder 2 contracts by the load, or the backstay 3 which supports the above-mentioned leader 4 by contraction | contraction by leakage is shrunk.

If this condition persists, shrinkage may occur due to load or leakage on one of the backstay cylinders 2 of the plurality of backstays 3, one end of which is supported by the outriggers to support the leader 4 in a balanced manner. When generated, the backstay 3 also contracts, so that the balance of the plurality of backstays 3 supporting the leader 4 is broken. As a result, the entire driving ride is conducted by the conduction of the leader 4, resulting in a safety accident.

Accordingly, the object of the present invention is to prevent the backstage cylinder supporting the leader used in the construction of the pillars or piles during the foundation work of the building, and to prevent shrinkage due to self-weight or leakage of equipment when the work is interrupted for a long time. To prevent falling of the backstage cylinder even when leakage occurs in the backstage cylinder, it is to provide a fall prevention device of anti-taking to ensure safety by preventing the conduction of the leader.
