Product Description

Product Description

The crawler spider crane, also known as a mini spider crane or mobile spider crane, is a compact lifting solution designed for operations in confined and sensitive environments. Its spider-like structure, combined with a rubber crawler system, allows stable movement and precise lifting where conventional cranes cannot operate.
 
With a lightweight, compact body and low ground pressure, this crane can access narrow passages, rooftops, upper floors, and indoor spaces. It is widely used for lifting tasks such as glass installation, handling steel structures, positioning equipment, and transporting landscape trees.
