Engineering a Mobile Two-Wheeled Crane System for Enhanced Port and Marine Cargo Handling Efficiency

This paper explores the design and feasibility of a hydraulic crane tailored for integration with two-wheeler vehicles in port operations, aimed at lifting loads up to half a ton (500 kg). The design methodology focuses on critical parameters such as hydraulic cylinder capacity, arm length, wheel capacity, frame strength, stability, power source, and electronic system. The hydraulic cylinder is sized to exert a lifting force of 4905 N, accommodating the specified load using a system operating at 700 bar. With an assumed arm length of 1 meter, stability is ensured through careful consideration of the counter-moment generated by the crane’s base. Wheel capacity analysis indicates each wheel must support at least 300 kg to safely manage the crane’s total weight, including the load. Structural integrity is addressed through stress calculations to determine appropriate material selection and frame design. Power requirements for the hydraulic system, calculated at 700 kW, highlight the need for an efficient electric motor to drive the hydraulic pump. An integrated electronic system with load monitoring sensors and a microcontroller ensures precise and safe crane operations. This comprehensive design framework provides a blueprint for developing compact, efficient hydraulic cranes suitable for enhancing operational capabilities in port environments, enhancing productivity while maintaining safety standards.
