Girder transporting machine

Weihua's girder transporting machine is mainly used in bridge prefabrication yards for the safe and smooth transfer of heavy precast concrete girders from the casting bed to the storage area or onto a girder transport trailer.
Specifications
  • Lifting capacity: 900t
  • Span: 36m
  • Working class: A3
  • Lifting height: 12m
Introduction

Weihua’s Girder Transporting Machine is mainly used in bridge prefabrication yards. It is specifically responsible for safely and smoothly transferring heavy precast concrete girders from the casting bed to the storage area or onto a girder transport trailer.

  • Equipped with a specialized spreader, it is mainly used for the loading, unloading, and transfer of large bridge girders.
  • The crane travel mechanism can achieve a 90º rotation, making it suitable for multi-span use.
  • The hoisting system utilizes a four-point lifting with three-point balance principle to ensure even force distribution on the wire ropes.
  • The trolley employs a hydraulic push rod device, enabling the lifting and transport of various bridge girders while also saving costs.

Although the specific design of Weihua’s Girder Transporting Machine may vary, its core typically includes several systems listed in the table below:

ComponentMain Function & Technical Key Points
Crane Travel DeviceDrives the entire machine longitudinally along rails laid on the ground. Typically uses multi-wheel bogies and motor drives.
Hoisting DeviceResponsible for lifting and lowering the precast girders. Usually employs a large-tonnage (e.g., 320-ton class) synchronized jack system to ensure smooth lifting and lowering of the girder.
Support Frame StructureThe main steel structure that bears the weight of the girder. Typically consists of two main girders and connecting crossbeams, forming a stable load-bearing platform.
Electrical Control SystemThe “brain” of the machine. Controls the coordinated operation of all mechanisms, especially ensuring the high-precision synchronization of multiple jacks during lifting and lowering, which is crucial for ensuring safety.

Features & Advantages

High Reliability & Safety
As special lifting equipment, its design strictly follows safety codes. Key components, such as hydraulic and electrical systems, have ample safety margins.
Strong Load Capacity
To meet the handling demands of heavy precast girders (up to thousand-ton class), its structural design and component selection are tailored to satisfy large-tonnage, high-strength operational requirements.
Precise Synchronous Control
Advanced electronic control systems ensure synchronous operation of multiple lifting points, preventing the girder from being twisted or cracked during transport.
High Degree of Automation
May integrate functions such as automatic positioning and path planning, reducing reliance on operator experience and improving operational efficiency and consistency.

Applications

Due to its powerful lifting capacity and specialized design, Weihua’s Girder Transporting Machine is mainly used in the following scenarios:

  • Core Application Field: Hoisting, erecting, and construction of precast girders for various railway and highway bridges.
  • Wide Industrial Application: The product is also widely used in numerous industries requiring heavy lifting, such as machinery, metallurgy, mining, electric power, railways, ports, petroleum, and chemical engineering.
