Double-beam Gantry Cranes for Lifting Building Materials

Double-beam gantry cranes (referred to as "double-beam gantry cranes") for lifting building materials are large-scale lifting equipment commonly used in the industrial and construction fields, especially suitable for loading, unloading, handling and stacking heavy building materials such as steel, cement products, prefabricated components, etc. It has a stable structure, large lifting capacity and a wide operating range, which can meet the high-intensity and high-frequency requirements of building material lifting.

Core advantages for building materials lifting:
Large lifting capacity: The lifting capacity is usually 10-500 tons, and it can easily lift several tons to dozens of tons of steel (such as H-shaped steel, steel pipes), prefabricated floor slabs, concrete pipe piles and other heavy building materials.
Large operating span: The span of the main beam can reach 10-30 meters or even larger, which can cover a wide material yard or workshop and reduce the secondary handling of building materials.
High stability: The double-beam structure is more rigid than the single-beam gantry crane, and has better anti-lateral bending and deflection performance. When lifting long strip building materials (such as steel and steel bar bundles), it is not easy to cause the main beam to deform due to the center of gravity shift.
Efficient operation: The lifting and running speed can be adjusted according to the type of building materials (such as low speed and stability when lifting fragile building materials, and efficiency can be improved when handling steel), and the turnover efficiency can be improved with linkage operation (hoisting + trolley + trolley synchronous operation).2. Applicable scenarios and typical building materials lifting cases

Main applicable scenarios:
Construction site material yard: lifting steel bars, steel pipes, scaffolding, prefabricated panels, etc.
Building materials production plant: such as steel structure plant lifting steel components, cement plant handling cement clinker, prefabricated component plant transfer concrete beams/columns.
Logistics storage terminal: stacking steel plates and stones in building materials warehouses, loading and unloading containerized building materials (such as prefabricated modules) at ports.
Typical lifting cases
Lifting bundles of steel bars: use special lifting equipment (such as beam-type lifting equipment with multiple hooks) to ensure the horizontal balance of the steel bar bundles to avoid tilting and scattering; accelerate slowly during lifting to prevent inertia from causing the steel bars to slide.
Lifting large prefabricated components (such as bridge beams and wall modules): special lifting rigging (such as balance beams and slings) is required to ensure that the lifting points are evenly stressed. The large lifting capacity (more than 50 tons) and stable operation capacity of the double-beam gantry crane can meet the safe transportation of such components.
Stacking of steel plates/profiles: Accurate stacking of building materials is achieved through the lateral movement of the trolley and the longitudinal movement of the truck. The low deflection characteristics of the double-beam structure can ensure the horizontality during stacking and avoid deformation of profiles.
