The beam carrier is a special equipment used to transport precast concrete elements. From the prefabrication yard, the beam carrier will transport the precast concrete elements to the construction site safely and efficiently, and cooperate with the bridge erection machine to complete the bridge erection. Beam carriers are usually designed to meet the performance requirements of heavy load, high precision and high stability, and are often used in large-scale infrastructure projects such as highways, railroads and urban rail transit.
According to the design specification of the bridge, the load range of beam carrier is usually from 50 tons to 2000 tons. The beam carrier is controlled by multi-axis linkage and load sensors to ensure the weight of the girder is evenly distributed, avoiding the concentration of force.
The steering function of the beam carrier is designed to adapt to complex road conditions. It is equipped with all-wheel drive and high/low speed switching function, which can drive safely and stably on the road surface with a gradient of 10% or less. At the same time, the minimum turning radius of the truck varies according to the model, usually 10-30 meters, so as to better adapt to the narrow construction site.
The beam carrier is equipped with a hydraulic balancing system, which can monitor the tilting angle of the body in real time, thus preventing the accidental occurrence of overturning. In addition, the beam carrier is equipped with multiple braking system, short emergency braking distance, to maintain the stability and safety of the body.
Convenience of operation is reflected in the integrated control interface in the cab of the beam carrier, which supports manual/automatic mode switching, and the remote control function can be accurately operated within the line of sight. During transportation, the beam carrier can control the deviation of the girder body position within 5mm, which meets the high precision requirements of bridge erecting machine docking.
The body of the beam carrier is designed as a detachable frame, which can adjust the wheelbase/wheelbase to adapt to the transportation of different lengths and types of girders, and it can also work stably under the environment of -20℃~+50℃.
The emergence of beam carrier accelerates the progress of bridge project, it can cooperate with girder lifter or gantry crane, the single loading and unloading time is less than 30 minutes, and the speed of transportation is 5-15km/h. Along with the development of electrification of machinery, the new energy beam carrier of lithium battery type is gradually used to improve the economic efficiency.
The beam carrier is usually the transportation equipment that works with the bridge erecting machine and girder lifting machine. Its use significantly improves the industrialization and mechanization level of bridge construction and shortens the construction period.
