Product Description
Goliath / Gantry Cranes are running on rails installed at ground level. The above image shows two such cranes working in tandem. Such cranes are used at –
- Construction sites
- Ports and harbours
- Workshops where existing columns cannot bear the wheel loads of a bridge crane
- Sites / projects where crane itself needs to be relocated from one place to another Locations where loads are to be shifted from points outside the crane span as in the case of an overhang on either side of the rails
- Out door fabrication yards
In workshops where part utilization of shop bay is required (as in a tool room attached to a press shop), Semi-Goliath/Gantry Crane shall be 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.
Gantry or semi gantry cranes can be either of the Single Girder type or Double Girder type.
The cost analysis between an EOT crane and a Goliath/Gantry Crane shall be done in the following ways and can be decided accordingly.
- 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
If required, APEX Engineers can share their expertise to the end users of the type of crane to be installed based on a cost benefit analysis.
