Where is the Modular Design of a Double-girder Mobile Gantry Crane Reflected?
2025-11-18
This is a very accurate question. The core of the modular design of a double-girder mobile gantry crane lies in three dimensions: structural modularity, functional combinability, and component standardization.

I. Modular Structural Combination: The core structure is broken down into independent modules such as the main beam, legs, end beams, and traveling trolley.
Each module is designed according to a unified standard and can be flexibly assembled according to span and lifting capacity requirements.
Disassembly is performed during transportation, followed by rapid on-site assembly, reducing transportation and installation difficulties.
II. Functional Mechanism Combination: The hoisting mechanism, trolley traveling mechanism, and auxiliary trolley traveling mechanism can be combined as needed.
Optional functional modules include frequency conversion speed regulation, anti-sway devices, and weighing and metering.
Different auxiliary devices (such as windproof rail clamps and rainproof covers) can be combined for different working conditions (such as outdoor storage yards and workshop transfers).
III. Component Standardization Combination: Key components (motors, reducers, brakes, etc.) use standard universal parts.
Non-standard components (such as special lifting tools and customized leg heights) are seamlessly integrated with standard parts. Consumable parts are standardized to facilitate future replacement and maintenance.
