Description
Qisong Qi and colleagues modelled transient energy use in 2026 for bridge cranes under coupled mechanical-electrical dynamics. Cranes lift heavy loads across factories and ports, yet energy ratings miss how motors and mechanisms interact moment by moment. Dynamic models for hoisting, trolley, and gantry travel were joined to an induction-motor electrical model for instantaneous power and cumulative energy.
Tests on a 1.5-tonne, 6-metre double-girder crane at 20 to 30% of rated load matched simulation within about 2% for two payloads, inside a 3% measurement uncertainty band. Simulated cycle energies were about 16,161 and 18,449 joules against measured 16,439 and 18,787 joules. The framework gives a sound basis for green crane assessment within its tested load boundary.
