Gantry Cranes

In workshops where part utilization of shop bay is required (as in a tool room attached to a press shop), a Semi-Goliath/Gantry Crane is used. In such a configuration one end-carriage of the crane will travel on the regular gantry rail while the opposite end-carriage will travel on a rail mounted typically on the ground or at a lower elevation.
A Goliath/Gantry Crane is typically more expensive than an equivalent EOT Bridge Crane. However in almost all the relevant cases as mentioned above, a cost analysis shows that it is cheaper to go in for a Goliath / Gantry Crane as against a Bridge Crane. The cost analysis can be done by taking into consideration the following - 

Cost of Gantry Girders that are required in case of a Bridge Crane 
Cost of Columns required for supporting the above Gantry Girders 
Difference in costs of civil foundation for columns (for Bridge Cranes) versus civil foundation for gantry rails (in Goliath / Gantry Cranes) 
Difference in Down Shop Leads cost of Bridge Crane versus Cable Reeling Drum and Cable Cost for a Goliath / Gantry Crane 
Goliath / Gantry Cranes can be either of the Single Girder type or Double Girder type.

If required, Magco Cranes can advise end users of the type of crane to be installed based on a cost benefit analysis.
