Beam Launcher Crane

Beam Launcher Cranes have a wide range of applications in bridge construction, and the following are the main types of applications:

• Walking bridge erecting machine: widely used in the installation of simply supported beams (slab beams, box beams, T-beams) for curved bridges, inclined bridges, and straight bridges, with good stability performance and the ability to achieve full section mechanized beam dropping and moving.
• Double guide beam bridge erecting machine: structurally stable, with strong bearing capacity, excellent lateral stability, strong adaptability, especially suitable for curved and inclined bridges, and more convenient for erecting outer beams. Suitable for the construction of railways, bridges crossing highways, and bridges with high piers.
• Single guide beam bridge erecting machine: designed with a single arm, the guide beam can expand and contract back and forth, lift and lower up and down, and move horizontally left and right, and can continuously erect different types of bridges. The new single guide beam bridge erecting machine is equipped with a slow lateral movement mechanism, which facilitates the adjustment of beam dropping and moving.
• JQ900A gantry bridge erecting machine: suitable for the construction of various bridges such as highways, railways, etc., such as highway bridges, conventional railway bridges, and passenger dedicated railway bridges. Capable of independently completing tasks such as lifting, moving vertically, horizontally, and dropping beams.
• Single beam bridge erecting machine: The lifting arm is designed as a box girder with the ability to enter the bridge position on its own. It is supported on the bridge pier by folding the column and can move flexibly when unloaded.

In summary, bridge erecting machines have various application forms in bridge construction and can adapt to different types and complex conditions of bridge construction needs.

The following are several types of basic structures of bridge erecting machines:

• Main beam: The main beam is the main load-bearing component of the bridge erecting machine, usually made of steel or steel truss structure, responsible for supporting and bearing the weight of the bridge.
• Leg system: The leg system is used to support and stabilize the bridge erecting machine, ensuring its balance and stability during operation. Legs are usually composed of hydraulic cylinders that can be extended or retracted as needed.
• Lifting system: The lifting system is used to lift and lower the main beam to achieve the construction and demolition of bridges. The lifting system is usually driven by hydraulic cylinders or hydraulic motors, and the lifting and lowering of the beam body is achieved through winches or hydraulic systems.
• Transportation system: The transportation system includes the tracks, tires, or track systems used for the movement and transition of the bridge erecting machine, as well as the corresponding power sources (such as diesel engines or electric motors).
• Control system: The control system is responsible for controlling and adjusting various operations of the bridge erecting machine, including lifting, lowering, and extending movements. Control systems typically include control consoles, electrical systems, and hydraulic systems.
• Auxiliary components and equipment: The bridge erecting machine may also include some auxiliary components and equipment, such as safety protection devices, lighting equipment, communication equipment, etc., to improve the efficiency and safety of construction.
• Beam: The beam is the main load-bearing component of the highway bridge erecting machine, responsible for bearing the weight of the bridge deck and suspension cables.
• Crane mechanism: The crane mechanism is the core part of the highway bridge erecting machine, including the electric drive system, braking system, wire rope, hook, pulley, and drum. The lifting mechanism is mainly used for hoisting and moving bridge decks.
• Mobile mechanism: The mobile mechanism includes a walking mechanism and a steering mechanism, used to move the highway bridge erecting machine to the location where construction is required. The walking mechanism usually adopts a track or wheel structure, and the steering mechanism can be achieved by rotating the vehicle body or adjusting the front and rear wheels.
• Support system: The support system is used to support the stability of the highway bridge erecting machine, including legs, pillars, and support frames. The support system can be adjusted according to different construction situations.
• Control system: The control system is used to control the movement and operation of the highway bridge erecting machine, including the cab, control console, sensors, cables, etc. The control system can be operated manually or automatically.

The above are the main types of basic structures of bridge erecting machines. It should be noted that there may be differences in the specific composition of bridge erecting machines of different models and specifications.

The technical characteristics of the Beam Launcher Crane include:

• Diverse structural forms: According to different structural forms, bridge erecting machines can be divided into main types such as tower erecting machines, cantilever erecting machines, and gantry erecting machines, each with unique characteristics and applicable scope.
• Different homework methods: According to the different homework methods, bridge erecting machines can also be divided into two types: fixed and mobile. Fixed bridge erecting machines are usually installed in fixed positions on bridge construction sites and are suitable for long-term construction and maintenance of specific bridges; Mobile bridge erecting machines have mobility and can move freely between bridge construction sites, making them suitable for construction operations on multiple bridges.
• Rapid construction and high load-bearing capacity: The road and bridge erecting machine adopts reasonable technology and design, which can quickly achieve the construction of roads and bridges, has a large load-bearing capacity, and can bear the huge weight of prefabricated components and beams.
• Automated operation: Equipped with automation systems and control technology, making operations easier and more accurate. Workers can complete complex construction tasks through remote control or preset programs, improving work efficiency and reducing the risk of human errors.
• Flexibility and adjust ability: The bridge erecting machine has strong flexibility and adjust ability, and can be adjusted and adapted according to the shape and size of the bridge to meet the construction needs of different bridges. It can also move and position freely on the construction site.
• High precision lifting: By using a double guide beam structure, the lifting and precise positioning of beam segments can be achieved, and lifting, rotation, and translation actions can be carried out in the air to meet the precise operation requirements of bridge components.
• Strong adaptability: The new bridge erecting machine has a detachable structure that can be locally modified according to specific conditions. It has strong adaptability and can erect single simply supported box girders with various spans of 32 meters or less, as well as unequal span girders. It has the function of reversing and erecting girders and can adapt to the needs of various road flatbed trucks and railway transportation girders.
• Loose transportation conditions: Except for some components, there are no strict requirements for the transportation conditions of other components. They can be transferred as a whole or disassembled before transfer, and the reassembly time is short.
• Stable and reliable operation: Using electronic frequency conversion speed regulation technology, the beam runs smoothly with almost no impact, improving reliable operation.

In summary, the technical characteristics of Beam Launcher Crane cover multiple aspects such as structural form, operation mode, automation, flexibility, precision, adaptability, transportation convenience, and smooth operation. These characteristics together ensure the efficient, safe, and reliable operation of bridge erecting machines in bridge construction
