Single beam crane is a common lifting equipment, and its main structural characteristics are as follows:

1. Single beam structure: The single beam crane adopts a single beam structure, which means that only one beam supports the lifting of goods. This structure makes the crane simpler and more compact, suitable for small and medium-sized lifting tasks.

2. Beam material selection: The beam material of a single beam crane is usually made of steel, such as high-quality alloy steel. This material has high strength and stiffness, and can withstand large loads and motion forces.

3. Truss structure: The beam of a single beam crane usually adopts a truss structure, which is a structure composed of multiple truss units. This structure can maintain the strength of the beam while reducing its own weight and improving operational efficiency.

4. Support system: The single beam crane supports the main beam through the support system. The support system includes support piers and cantilever brackets on both sides, which can stably support the weight and load of the beam.

5. Lifting mechanism: The lifting mechanism of a single beam crane usually uses an electric hoist or a chain type lifting mechanism. This type of mechanism can achieve the up and down movement of goods and has the characteristics of stability and safety.

6. Control system: The control system of a single beam crane usually adopts an electronic control system or a hydraulic control system. The control system can achieve functions such as switching, lifting, and moving of the crane, making operation more convenient and precise.
