1.Single column roadway stacker The single-column stacker adopts a rectangular frame structure consisting of one column and two beams. Although the frame structure will be inferior in strength, it is more flexible and the lifting weight is generally less than 2 tons. For lifting small objects, the lifting height is generally within 16 meters.
2. Double column roadway stacker This type of stacker consists of two vertical columns and two beams. The structural stability and strength are improved to a certain extent compared with the single-column roadway stacker, and the weight is heavier than the single column type. The stability of the device is stronger. The double-column channel stacker can lift up at a variety of lifting heights, lifting weights up to 5 tons, and increasing the lifting weight according to actual conditions.
