Gantry Cranes


MAGCO- GOLIATH CRANES / GANTRY CRANES are self propelled cranes 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 harbors
Workshops where existing columns cannot bear the wheel loads of a bridge crane
Workshops with low roof tie height that might restrict the height of lift of a regular bridge crane
Locations where bay lengths are excessive
Locations where bay lengths do not remain constant
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 
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.

Standard Features of Magco Cranes' Goliath / Gantry Cranes -

  • Optimum design ensuring minimum Dead Weight, Wheel Loads, Head Rooms and Clearances, reducing building costs.

  • Forged runner wheels on Spherical Roller Bearings, resulting in long trouble free service.

  • Hobbed and Run-In Heat Treated Gears machined from High Carbon Steel / Alloy Steels to ensure smooth, silent and durable service.

  • Wide range of Heights of Lift, Hoisting, Cross & Long Travel Speeds to suit every operational requirement.

  • Amply proportioned Main Girders and Legs of Box section, fabricated from IS 2062 plates that have undergone rigorous quality testing. All butt welds are 100% radiographed. Main Girders and Legs further stiffened with long and short diaphragms.

  • End Carriages are made either from rolled sections or fabricated from plates.

  • 2 Legs are of flexible design while the opposite 2 Legs are of rigid design. Flexible Legs are joined to the Main Girders through hinged joints.

  • All Legs are braced.

  • Well proportioned Live Axle Type Runner Wheels on "L" type bearing housings.

  • Rope Drum fabricated from seamless pipes (ASTM A-106 Grade B) or from IS 2062 plates. The Rope Drum is stress relieved and the long seams are 100% radiographed.

  • Standardized sub-assemblies used for complete range ensures quick supply of spares in case of emergencies or routine maintenance.
