Crane Engineering Centre
Calculators and technical decision centre
These tools provide a consistent starting point for capacity, hoisting power, cycle time, approximate wheel load and duty intensity before the site review.
Preliminary hoisting motor power
Calculates theoretical power from moving mass, lifting speed and mechanical efficiency.
Enter values to begin.
Approximate cycle time
Combines lifting, travel and dwell periods into one operating cycle.
Enter values to begin.
Approximate wheel-load distribution
Distributes lifted load, bridge and trolley mass across wheels for preliminary structural review.
Enter values to begin.
Preliminary duty profile
Profiles operating intensity using daily hours, cycles per hour and average load ratio.
Enter values to begin.
Engineering validation is mandatory
Results are preliminary and do not replace engineering. Structural capacity, fatigue, mechanism classification, acceleration, braking, wind, seismic effects, temperature, misuse and applicable regulations are outside these simplified tools.
Load spectrum
How often the crane lifts light, medium and near-rated loads determines fatigue demand.
Duty cycle
Operating hours and cycles influence motors, brakes, reducers, ropes and structural life.
Facility interface
Runway alignment, structural stiffness, power supply and access affect reliable operation.
Safety functions
Overload protection, limits, emergency stop, brakes and controls must work as a coordinated system.
