Bridge Girder Launcher

Description

Bridge Girder Launcher is a heavy lifting equipment specially designed for bridge construction. It has strong load-bearing capacity and high operating accuracy, and can efficiently and safely complete the lifting and installation tasks of prefabricated beam sections. Its overall structure is complex and powerful, mainly including main beams, legs, lifting trolleys, electrical control systems and other auxiliary devices.

Structure

The main beam is the core bearing structure, usually made of high-strength steel, with excellent rigidity and stability. The main beam is designed with bending and torsional resistance to ensure that there is no deformation or damage when lifting heavy objects.

The legs are divided into front legs and rear legs, which are at both ends of the main beam, supporting the entire equipment and ensuring its stability during operation. The legs are usually height-adjusted and moved using hydraulic systems to adapt to different terrain conditions and construction requirements. The front legs are generally fixed on the paved bridge deck, while the rear legs can be moved on the track to facilitate the positioning and adjustment of the equipment.

Lifting trolley is on the main beam and is responsible for lifting and handling prefabricated beam sections or other heavy-duty components. It is equipped with an electric or hydraulic drive system, which can achieve precise lifting and lateral movement. Through frequency conversion speed regulation technology, the lifting trolley can remain stable when starting and stopping, reducing impact on the components, and ensuring accurate positioning of the bridge components.

In addition, there are some auxiliary devices, such as balance beams and rail systems, to ensure that the equipment remains balanced and stable during the lifting process. The balance beam is to adjust the load distribution between different lifting points. The guide rail system ensures smooth operation of the legs and trolleys on the tracks, improving overall operating efficiency.

The bridge girder launcher can meet a variety of complex construction environments and task requirements. Whether crossing rivers, valleys or urban roads, bridge builders can efficiently and safely complete the construction of bridges.

Features

1. Strong load-bearing capacity: for lifting and installing heavy-duty prefabricated beam sections, with extremely high load-bearing capacity and stability, ensuring safe operation under complex working conditions.
2. High operating accuracy: with advanced frequency conversion speed regulation system and precise positioning device, achieve smooth start, stop and accurate positioning, and improve construction quality.
3. Flexible adaptability: The legs and main beams can be adjusted according to different terrain and bridge spans, adapting to a variety of complex construction environments, and have strong flexibility.
4. Comprehensive safety protection: Integrate multiple safety protection devices such as overload protection, limit switches and emergency stop buttons to ensure high safety during operation and reduce accident risk.

Application
