HOLDING DEVICE FOR WINCH DRUM IN CRANE

摘要

PROBLEM TO BE SOLVED: To provide a holding device for a winch drum satisfying requirements of (1) facilitating transportation of a crawler crane and a basic machine, (2) minimizing space required for works of the crawler crane and the basic machine and (3) facilitating manufacturing and assembling of the crawler crane and the basic machine, by simplifying structure in view of conventional technical problems. SOLUTION: This holding device for the winch drum is supported on one side by a reduction gear holder via a driving device and supported on the opposite side on a side wall surface of a revolving frame via a bearing holder. The bearing holder has a bolt hole on the end face and is fixed by screwing a fixing bolt into the bolt hole from the outside of the side wall surface of the revolving frame.
