Cartesian gantries used in heavy lifting applications often require two Z axes linked together, with two racks fitted to the structure separately in order to provide sufficient lifting force. The ESR has been specially developed to be used singularly to address this issue, although double arrangements can be configured for particularly heavy loads.
In common with the guides from the Hepco Heavy Duty HDS2 system, the rack is integral with the V guide. This is claimed to ensure parallelism with the guide V running surface offering smooth motion over the entire travel length.
The whole package is complimented by a hardened and ground 15 tooth pinion that can be fitted into standard HDS2 carriage plates. The design enables a geared motor/flange arrangement to be located directly to the carriage, taking up minimal space.
