Mobile chassis frame carried by friction rollers - has clip=on roller support for replacing roller without dismounting chassis

摘要

The rollers (1) are carried by a cope (2) which has a lateral spindle (5) for clipping onto the wings of the clip (6). The clip is solid to an intermediate support piece (7) between the mobile chassis and the cope and the intermediate piece is regulated in position and locked to the profile of the mobile chassis by screws (11) and spacers (12). The cope carrying the rollers is locked in position by a progressive ramp (6A) of the clip and by a regulatable stop (13) which is supported by the intermediate piece (7) and pushes onto end (2A) of the cope.
