ABSTRACT:
There is described an apparatus for storing and conveying standing, tubular workpieces (1) made of concrete in layers arranged one above the other, comprising a load pick-up device (6) to be connected to a hoist (2) and designed for at least two workpieces (1), which load pick-up device consists of a holding frame (11) extending above the workpieces (1) to be picked up and of holding arms (14) encompassing the workpieces (1) on the outside, which holding arms are mounted on the holding frame (11) so as to be movable transverse to the workpieces (1) and engage below a flange (15) of a bottom ring (16) of the workpieces (1), and comprising storage racks (21) to be coupled individually to the load pick-up device (6) and bridging the workpieces in the manner of a portal for accommodating the workpieces (1) in a further layer. To create advantageous constructional conditions it is proposed that one storage rack (21) bridging the workpieces (1) to be seized by the load pick-up device (6) can each be coupled with the load pick-up device (6).
