PURPOSE:To obtain a running type precipitated sand scrape-up apparatus wherein the traversing conveyor of a conventional running type precipitated sand scrape-up machine is dispensed with and the scrape-up apparatus is placed on a precipitated sand accumulation layer and enabled in inspection at a part above water while power consumption is reduced and handling is made simple. CONSTITUTION:A saddle having wheels arranged to both ends thereof is placed on rails 15 and a girder 2 is arranged to the saddle so as to straddle a sand precipitation basin 1 while a vertical frame 9, a lift apparatus 13, a chute 18 and a casing 20 supporting a chain wheel 3 are provided to the single side of the girder 2 and sheave wheels 11 are provided to both sides of the girder 2. A transverse frame 8 is provided to the sand precipitation basin 1 under the girder 2. Then, tensioning of a chain by the rising and falling of vertical and transverse frames 9, 8 is performed by the tensioning chain wheel 4 provided to the frame 9. The chain 7 provided with buckets is mounted over the chain wheel 3, the tensioning chain wheel 4 and underwater chain wheels 5 and moved by a drive apparatus 14.
