MDG (L) type single-girder gantry crane is a GB‑standard general‑purpose light‑duty gantry crane. The whole machine adopts L-shaped outriggers and a single-box main beam structure. It is designed and manufactured in strict compliance with the GB/T14406 national standard. The equipment does not need to rely on the steel structure of the factory building, but relies on ground tracks to move independently. It has a simple structure, light weight, convenient installation, and high cost performance. It is the main equipment for material loading, unloading, transportation, and stacking in outdoor cargo yards, storage yards, construction sites, and open spaces in factories. The L-shaped outriggers are designed with reasonable force, small floor area, and large passage space. They are suitable for various conventional open-air working scenarios. They can be flexibly matched with electric hoists to complete lifting operations. They are widely used in outdoor lifting conditions of medium‑light duty cycle and medium‑tonnage applications.

Core advantages

The MDG (L) single-girder gantry crane has strong comprehensive practicability and a wide range of adaptability scenarios. It has multiple core advantages: the whole machine is welded and formed from high-quality steel. The box-shaped main beam has strong rigidity, resists deformation and wear. The L‑shaped outrigger structure features well‑engineered design with even and stable force distribution, ensuring safe and reliable operation and long service life and reliably, and has a long service life; it does not need to be attached to a factory building, and operates independently on the floor without being restricted by the factory structure. It is perfectly suitable for outdoor open spaces, temporary construction sites, and working areas without factory buildings, making up for the shortcomings of bridge cranes that cannot operate outdoors; The equipment has a simple structure, light weight, small wheel pressure, low ground foundation requirements, short production and installation cycle, low operation and maintenance costs, and extremely cost-effective overall. The operating mechanism adopts split drive, which ensures smooth travel, precise braking and anti‑slip performance. It comes standard with multiple safety protection devices to eliminate potential hazards including overload and over‑travel; it supports three operating modes: ground operation, remote control, and cab control. It can be equipped with a variable frequency speed control system as needed to achieve smooth start and stop and precise alignment. It also supports non-standard sizes and customization for special working conditions, and has strong adaptability.
