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 accelerat
ing 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 c
ycle permits, for
reduced base load, dynamic accelerating
phases. Typical applications when desig
n-
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
