The single girder overhead crane mainly consists of a main girder, end trucks, electric hoist, H-beam track, electrical system, and control unit. The hoisting mechanism is usually paired with CD or MD type wire rope electric hoists, or the new Chinese low-clearance electric hoist. The structure is compact, and operation is smooth and stable.
It is widely used in manufacturing plants, workshops, warehouses, power stations, and steel mills for lifting and handling materials. The main beam is mounted on columns or metal supports on either side of the building, forming a bridge structure. The electric hoist travels along the rail under the main beam to perform lifting operations.
The crane supports ground control, remote control, or cab control, offering flexible operation modes to suit user needs. Dafang Crane supplies high-quality overhead cranes certified to international CE standards, known for safety, energy efficiency, low noise, and environmental friendliness.
The LD type single girder overhead crane is easy to operate and requires minimal maintenance. It performs lifting tasks efficiently and reliably, making it a cost-effective and high-performance lifting solution favored by many users.
Single beam overhead cranes are widely used in workshops, warehouses, logistics centers, and other places, suitable for lifting and handling light to medium loads. They are commonly found in small to medium-sized factories, especially in environments where space is limited. They improve operational efficiency in a variety of industrial sectors, including machinery manufacturing, automotive industry, food processing, etc. With a simple structure and easy maintenance, this crane is the preferred choice for many customers.
