Overview
The Self-balancing Beam Launcher is a new type of bridge construction equipment developed based on the walking beam launcher. It is designed to improve the efficiency and safety of bridge construction by eliminating the need for counterweights and beam transport vehicles during the erection process.
Main Features
Structure : The self-balancing beam launcher mainly consists of a main beam, front, middle and rear legs, front auxiliary outriggers, upper cross beam, crane, transverse moving track, and hydraulic and electrical systems. The main beam is usually made of high-strength steel and has a truss structure, which provides good load-bearing capacity and wind resistance.
Lifting Capacity : The lifting capacity of self-balancing beam launchers ranges from 80 tons to 300 tons or more, depending on the specific model and configuration.
Span and Lifting Height : The span can be from 30 meters to 50 meters, and the lifting height is generally between 6 meters and 12 meters.
Power Supply : It can be powered by 3 – phase A.C. 50Hz 380V electricity or diesel engines.
Advantages
High Efficiency : The self-balancing beam launcher does not need the assistance of a beam transport vehicle to complete the hole passing independently. After the beam transport is completed, the beam launcher can directly return to the beam yard, which greatly improves the overall erection efficiency.
Safety and Reliability : It is equipped with various safety protection devices such as emergency stop, overload protection, stroke and lifting limit switch, undervoltage and lack of phase and overcurrent protection, etc., ensuring safe and reliable operation.
Versatility : It can erect straight, curved, and longitudinally equal – span and variable – span double – line prestressed concrete whole – hole box girders. It can also adapt to bridges with different slopes and angles.
Convenient Operation and Maintenance : The self – balancing beam launcher has a simple structure and is easy to operate. It is also easy to disassemble and transport, which is convenient for maintenance and repair.
Applications
Bridge Construction : The self-balancing beam launcher is widely used in the construction of highway and railway bridges. It can be used to erect beams on bridge piers, improving the construction efficiency and quality.
Infrastructure Projects : It can also be used in other infrastructure projects such as viaducts, overpasses, and tunnels.
In conclusion, the self – balancing beam launcher is an advanced and efficient bridge construction equipment with many advantages. It has a wide range of applications and can greatly improve the efficiency and safety of bridge construction.
