ON-PILE CRANE DEVICE OF PILE ROW EXECUTION WORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an on-pile crane device of a pile row execution work system capable of miniaturizing/simplifying the whole constitution while securing crane handling capacity and a degree of freedom of a combination of components according to an execution work site. SOLUTION: In this on-pile crane device 1 composed of a crane 5 for delivering a pile between a pile press-in extractor and a pile carrying device and an on-pile self-traveling mechanism for movably holding the crane 5 on a pile row, the on-pile mobile mechanism has a mounting mechanism 8 being mounted with an engine unit 6 for supplying driving oil pressure to the pile press-in extractor and detachably fixing the engine unit 6 to constitute the on-pile crane device of a pile row execution work system.
