摘要

The workshop trolley (10) has base surface (14) whose corners are provided with roller mounting plates (18) for rotatable mounting of rollers (12). The metallic structures (24) are arranged above the base surface. The rollers are pivotable around vertical axles (11). The operations of rollers are controlled by brake devices (38). The adjacent rollers are coupled around vertical axles for synchronous pivoting.
