What is a Precast Gantry Crane?

A precast gantry crane is a lifting piece of equipment used in precast concrete beam yards for moving bridge beams from casting beds to storage areas or loading points. It is also known as a precast beam gantry crane or beam yard gantry crane. The crane is mainly used for lifting, transferring, and positioning precast concrete beams in highway bridges, railway bridges, and infrastructure construction projects.

The crane usually adopts a double-girder or truss gantry structure and is designed for large-span and heavy-load operations. It can be equipped with dual lifting points or two crane units to handle long and heavy precast beams. Truss-type cranes often use steel pipe legs and pin-connected beam sections, allowing easier installation, dismantling, and relocation. The working class is generally A3–A8, while double girder box-type gantry cranes are commonly designed as A5–A6. The crane can be customized according to beam weight, beam length, yard layout, and construction requirements.

Precast Gantry Crane is mainly used in precast beam yards for lifting and transferring concrete beams during bridge construction projects. According to different lifting requirements, beam sizes, and site conditions, it is commonly divided into Double Girder Gantry Crane, Truss Gantry Crane, and Tyre-mounted Gantry Crane.

رافعة جسرية مزدوجة العوارض

رافعة جسرية مزدوجة العوارض adopts a box-type main girder structure and is designed for heavy precast beam lifting. It consists of a gantry frame, trolley system, hoisting system, and electrical control system. The crane can work with double lifting points or two cranes operating together for large beam handling. It is widely used in highway and railway bridge construction.

• Lifting Capacity:5–320 tons
• Span:10–50 m

Tyre-mounted Gantry Crane

Tyre-mounted Gantry Crane uses rubber tires for movement and does not require fixed rails. It can move flexibly inside precast beam yards and is suitable for outdoor construction sites. The crane is powered by an internal combustion generator set or hybrid power system and is used for precast beam lifting, transfer, and loading operations.

• Lifting Capacity:10–200 tons
• Span:20–35 m (customizable)
• Lifting Height:10–30 m

A Precast Gantry Crane is composed of several systems, including the gantry structure, hoisting system, travel mechanism, lifting device, electrical system, and safety devices. These components work together to handle the lifting, transfer, and positioning of precast concrete beams in construction yards.

• Gantry Structure (Main Girder and Supporting Legs): The gantry structure uses box-type or truss-type main girders. Box girders provide high strength for heavy lifting, while truss structures reduce weight and improve wind resistance. Supporting legs are available in A-type and U-type designs.
• Hoisting System: The hoisting system consists of a motor, gearbox, drum, wire rope, and hook. It lifts and lowers precast beams with typical speeds of 5–8 m/min.
• Trolley Travel System: The trolley moves along the main girder and carries the lifting device for horizontal beam transfer. The travel speed is usually 2–30 m/min.
• Crane Travel System: The travel system includes drive motors, steel wheels, and rails, allowing the crane to move along the beam yard. The travel speed is generally 6–60 m/min.
• Lifting Device: The lifting device can be customized for different precast beams, including T-beams and box girders. Double lifting points or special lifting frames help keep beams stable during handling.
• Electrical Control System: The system uses PLC control and frequency conversion for crane operation. The standard power supply is 380V, 50Hz, 3-phase.
• Safety Protection System: Safety devices include overload protection, lifting limit switches, travel limit switches, buffers, and emergency stop systems.
• Operation Mode: The crane supports cabin control, ground control, and wireless remote control. The cabin can move with the trolley for better operation visibility.
• Rail System: Rail-mounted models run on fixed tracks for stable movement. Tyre-mounted models use rubber tires and can move without rails.
• Power System: The crane can use generator power (AC 380V±10%, 50Hz±1Hz) for outdoor yards or connect to external power through cable reels.

How Does a Precast Gantry Crane Work?

A Precast Gantry Crane moves precast beams through the combined operation of the hoisting system, trolley, and crane travel system. The crane lifts beams from the casting area, moves them to the storage yard or transport position, and completes beam placement according to the construction requirements.
