3-ton portable gantry crane is a medium-sized material handling equipment, which is widely used in factories, warehouses, freight yards, and other places.
This type of crane has the characteristics of simple structure, convenient operation, and economic practicality. It is an ideal choice for small and medium-sized enterprises to enhance production efficiency.
The rated lifting capacity of the 3-ton single-girder portal crane is 3 tons. The span is usually between 5 and 30 meters, and the lifting height is generally 6 to 12 meters. The working grades are mostly A3-A5, suitable for medium-intensity material handling operations.
The single-girder portal crane uses I-beam or box-shaped beams as the main girder, and the two ends are supported on the ground tracks by legs for operation. Compared with the double-girder structure, the single-girder design makes the overall weight of the machine lighter and the cost lower. The leg forms can be divided into rigid legs and flexible legs, and the choice depends on the site conditions.
