Double-Girder Overhead Crane Bridge Structure
The bridge structure of a double-girder overhead crane typically consists of two main girders, two end beams, walkways, guardrails, and other components, forming the primary supporting structure of the crane. The main girders are generally constructed as box girders, welded using the submerged arc welding (SAW) process, providing high strength and rigidity.
Trolley System
The lifting trolley is commonly assembled using an electric hoist or winch as the hoisting mechanism. It is available in both floor-operated and cabin-operated configurations, allowing users to select the appropriate mode based on specific operational requirements.
Duty Classification
Depending on the frequency of use, the crane is classified into Duty Classes A5, A6, and A7. Each duty class corresponds to different operating conditions and service life requirements.
Key Specifications:
Lifting Capacity: 1–200 t
Span: 7–35 m
Design Features: Incorporates European-Style crance technology. The hoisting mechanism can operate in single-speed, dual-speed, or variable frequency drive (VFD) modes. Speed can be finely adjusted, and inching operation frequency is increased.
Applications: Widely used in factories, warehouses, logistics centers, and similar settings.
