Climb electric hoist motor work level - s2 short work, run in a given time under constant load, the time is not enough to achieve thermal stability, then the fault could halt enough time, make the motor cooling again to the cooling medium temperature difference within 2 k. Climb the electric hoist motor, duty cycle work level - s3 every cycle includes a constant load running time and a broken can halt time Climb level s4 - including electric hoist motor starting, the duty cycle of every cycle includes a has a significant influence on temperature rise of starting time, a constant load operation time, and a broken can halt time. Climb electric hoist motor work level - s5 including electric braking, the duty cycle of each cycle including a starting time, a constant load operation time, a rapid electric braking time and a broken can halt time. Climb electric hoist motor work level - s6 cycle work week in a row, the same cycle time of operation, every cycle includes a constant load running time and a no-load running time, but no broken can halt time. Climb electric hoist motor work level - s7 including electric braking cycle work week in a row, each cycle including a starting time, a constant load operation time, and a fast electric braking time, but no broken can halt time. Climb level - the s8 including electric hoist motor speed and load of the continuous cycle of duty, every cycle includes a constant load under the preset speed running time, and one or a few segments under different rotational speed of other constant load running time, but no broken can halt time. Climb the work level integrated electric hoist electrical load and rotating speed of cyclical change work week, load and speed within the range allowed change aperiodic work week. This work includes often overload, its value can be far more than full load.
