Abstract (en)
[origin: EP2980001A1] A hoist life calculating device has a load calculating unit (21) that calculates a load suspended from a hoist (4) from the motor speed and the current value of a control inverter for the hoist, an operation cycle measuring unit (25) that counts both the number of lifting operations and the number of lowering operations of the hoist for each load calculated by the load calculating unit (21), an operating time measuring unit (24) that counts the operating time for each load calculated by the load calculating unit (21), and a remaining lifetime calculating unit (26) that calculates a loading rate from the operating time for each load measured by the operating time measuring unit (24) and that calculates the remaining lifetime of the device for hoisting from the obtained loading rate.
