Concrete Yard Gantry Crane | Double Girder Box Girder Goliath Crane
Short Video Description
This video shows a concrete yard gantry crane designed for segmental precast concrete handling. The double girder Goliath gantry crane is suitable for precast concrete yards, segment casting plants, bridge construction projects, beam storage yards and outdoor concrete material handling.
The double girder gantry crane uses a rigid box girder structure with ground travelling legs and an electric wire rope hoist or open winch trolley. It can be customized for lifting, transporting, stacking and loading precast concrete segments, bridge segments, concrete beams and other heavy precast products.
For segmental precast concrete handling, the crane design depends on the segment weight, segment dimensions, lifting points, span, lifting height, hook spacing, duty class, rail gauge and required travelling distance. Yuantai Crane reviews these parameters together before selecting the crane structure and lifting system.

Double Girder Gantry Crane for Segmental Precast Concrete
A double girder gantry crane for precast concrete is designed for handling heavy and oversized concrete segments in casting and storage yards. The crane travels on ground rails and can cover large outdoor working areas without requiring a building overhead crane runway.
For precast segment lifting, the crane capacity should be matched to the heaviest segment and the actual lifting arrangement. The segment dimensions, center of gravity and lifting points are important when selecting the hook spacing and hoisting configuration.
Yuantai Crane can provide single hoist, dual hoist or synchronized lifting systems for different precast concrete handling processes. The final configuration is determined by the segment weight, lifting points, working cycle and required positioning accuracy.
Box Girder Goliath Gantry Crane for Concrete Yard
A box girder Goliath gantry crane uses welded box-section main girders supported by gantry legs travelling on ground rails. The box girder provides a rigid structure suitable for heavy precast concrete handling and customized long-span applications.
Compared with a lighter gantry configuration, a double girder box girder Goliath crane provides more structural capacity for heavy loads and can accommodate different trolley, hoist and maintenance arrangements.
For an outdoor concrete yard, Yuantai Crane also considers wind load, wheel load, rail foundation, corrosion protection, electrical protection and travelling distance as part of the complete crane design.
FAQ: Concrete Yard Gantry Crane for Precast Segment Handling
Common questions about double girder gantry cranes, box girder Goliath cranes and segmental precast concrete handling.
1. What is a concrete yard gantry crane?
A concrete yard gantry crane is a ground-rail travelling gantry crane used for lifting and moving precast concrete products in casting and storage yards. It is commonly used for precast segments, beams, panels, columns and other concrete components.
Yuantai Crane can customize the crane according to the required capacity, span, lifting height, duty class and yard layout.
2. Why use a double girder gantry crane for precast segments?
A double girder gantry crane is suitable for heavy precast segment handling because its two main girders provide a rigid structure for the trolley and lifting system.
It is especially useful when the project requires higher lifting capacity, longer span, greater lifting height or heavy-duty operation.
3. Can a Goliath gantry crane lift precast concrete segments?
Yes. A Goliath gantry crane for precast concrete can be designed to lift, transport and stack heavy concrete segments in an outdoor yard.
The crane capacity, hook spacing and hoisting arrangement are selected according to the segment weight, dimensions and lifting points.
4. Can two hoists lift one precast concrete segment together?
Yes. A dual-hoist precast segment gantry crane can be designed for synchronized lifting when the segment requires multiple lifting points.
Yuantai Crane checks the load distribution, hook spacing, hoisting speed, girder strength and wheel loads before approving the synchronized lifting configuration.
5. What information is needed for a precast segment gantry crane quotation?
For a precast segment gantry crane quotation, provide the segment weight, segment dimensions, lifting points, capacity, span, lifting height, hook spacing, rail gauge, travelling distance and working frequency.
A segment drawing and concrete yard layout are especially useful for selecting the correct trolley arrangement and lifting system.
6. Is a box girder Goliath crane suitable for outdoor concrete yards?
Yes. A box girder Goliath gantry crane is well suited to outdoor precast yards where heavy loads must be handled over casting beds, storage areas and loading zones.
Yuantai Crane designs the crane with suitable wind protection, electrical protection, protective coating, wheel loads and rail foundation requirements according to the actual site environment.
7. What experience does Yuantai Crane have with precast concrete gantry cranes?
Yuantai Crane has engineering and manufacturing experience with double girder gantry cranes, box girder Goliath cranes, precast beam lifting cranes and concrete segment handling systems.
Yuantai's engineering work covers the main girders, gantry legs, hoisting system, trolley, lifting points, wheels, rails and foundation loads according to the actual precast concrete handling process.
