Antuo recently completed the installation of a 30-ton double-girder bridge crane for a steel processing plant in Surabaya, Indonesia. This crane is designed to handle heavy cylindrical components used in the manufacturing of large-scale industrial machinery.
This client specializes in the production of steel rollers and heavy machinery components—parts that require stable and precise lifting equipment during processing and assembly to ensure safe handling. The newly installed overhead crane has significantly enhanced material handling efficiency within the workshop.
The Indonesian client contacted ANTOP, outlining several key requirements regarding their lifting solution:
-
Lifting Heavy Cylindrical Steel Components
-
Ensuring Smooth and Stable Lifting During Precision Machining
-
Covering an Extensive Workshop Area
-
Enhancing Workshop Safety and Workflow Efficiency
Given the extreme length and weight of the steel rollers, the crane is required to provide exceptional load stability and precise positioning during lifting operations.
After analyzing the client’s workshop layout and lifting requirements, Antuo engineers recommended a double-girder overhead crane solution equipped with a high-performance electric hoist and an advanced control system.
The crane features a robust box-girder structural design, ensuring maximum rigidity and durability under heavy loads. The hoisting system facilitates smooth acceleration and deceleration, enabling operators to safely handle large steel components without vibration or swaying.
Furthermore, the crane is equipped with comprehensive safety protection systems—including overload protection, limit switches, and emergency stop functions—to ensure reliable operation during daily industrial use.
