A cantilever crane is a device used for lifting and moving heavy objects. Features: 1. The cantilever crane has a cantilever structure, which allows it to rotate and move around a fixed point, providing flexible operating space. 2. When combined with hoisting devices such as electric chain blocks, the cantilever crane features high efficiency and energy saving, suitable for short-distance, frequent use of hoisting operations. 3. Cantilever cranes are usually made from thickened pipes, have a compact structure, light self-weight, large span, high lifting capacity, and are economical and durable. 4. Cantilever cranes are typically installed on walls or columns, saving floor space and suitable for places with limited space.
