This single girder semi gantry crane is a general purpose light gantry crane in workshops or outdoors. The leg height of this single girder semi-gantry crane can be different according to the engineering needs on the construction field. It has the features of simple structure, easy installation, light weight, good wind resistance. The main girder is mostly bias rail box type structure.
This hoist semi gantry crane adopts modularization and parameterization design. And its hoisting mechanism adopts stable performance, durable and safe and reliable general-purpose wire rope electric hoist. The gantry running mechanism adopts vertical variable speed or three-in-one drive device drive respectively with conventional speed control system.
One of the characteristics of a single girder semi gantry crane is that it has outriggers on one or both sides, which are supported on the ground or moved by wheels. This design allows the crane to operate in a space that is not completely enclosed, such as an open side of a warehouse or an outdoor site.
Factories and warehouses: It could move and load materials, and is very useful in assembly workshops and storage environments, especially those where there is a need to cover a specific work area but limited space.
Material yards: Semi gantry cranes can effectively handle various material handling tasks and improve production efficiency.
Construction sites: For the construction industry, semi gantry cranes can handle building materials such as steel bars, precast concrete parts, etc.
Special environments: Some semi gantry cranes are specially for specific working conditions, such as clean room environments or operations in corrosive media.
Compact structure, small limit size;
Frequency conversion speed regulation, smooth running;
Perfect protection device, safe and reliable;
Integrated transmission, energy saving and high efficiency;
Mute drive, low noise and environmental protection.
