Load cycles and typical applications:
"Low Overload" load cycle
"High Overload" load cycle
The "Low Overload" load cycle assumes a
uniform base load with low requirements
placed on brief accelerating p phases. Typi-
cal applications when designing according
to "Low Overload" include:
•
Pumps, fans and compressors
•
Wet or dry blasting technology
•
Mills, mixers, kneaders, crushers,
agitators
•
Basic spindles
•
Rotary kilns
•
Extruders
The "High Overload" load cycle permits, for
reduced base load, dynamic accelerating
phases. Typical applications when design-
ing according to "High Overload" include:
•
Horizontal and vertical conveyor
technology (conveyor belts, roller
conveyors, chain conveyors)
•
Centrifuges
•
Escalators/moving stairways
•
Lifters/Lowerers
•
Elevators
•
Gantry cranes
•
Cable railways
•
Storage and retrieval machines
