A small cantilever crane is a lightweight lifting device that is ideal for transporting materials over short distances and with high frequency in factories, workshops, warehouses and other similar locations. Core structure and types: Its main components include a pillar, a rotating arm, a rotation drive mechanism, and an electric hoist. The pillar is fixed to the ground, the cantilever arm can rotate, while the electric hoist moves horizontally along the cantilever arm, enabling lifting operations in three-dimensional spaces. Common types: They are mainly divided into fixed types (such as those with a stationary pillar or wall-mounted types).
