Linear drive for moving heavy loads has guide with spaced shafts having bridge to form rigid assembly and with guide rails for carriage

摘要

The linear drive has a guide (2) with two parallel spaced shafts (7) having a bridging connection (14) to form a rigid assembly. Each shaft carries a guide rail (15) with both rails supporting a reciprocating carriage (5) with a longitudinal rod-less linear drive (6). Each shaft is a separate component with at least one having the drive and the bridging piece extending in the gap between the shafts.
