Abstract
The overhead travelling crane for handling hay, silage etc. inside a barn, has a crane trolley (1) with two longitudinal beams (5) and two cross beams (6) with a turntable (8) at the middle. Below this is the jib arm (12) for handling the load is supported. The trolley travels on four double roller assemblies (4) each with a front roller pair (14) and rear roller pair (15) which straddle the web of an I beam, to travel on its lower flanges. Each assembly has the rollers carried by horizontal side plates (18) extending forwards and rearwards from vertical channels (21), one each side of the longitudinal beams. The side plates are attached to intermediate horizontal members attached to the rear of the vertical channels (21), one each side of the longitudinal beams. The side plates, are attached to intermediate horizontal members attached to the rear of the vertical channels.
