“YOYO” ELECTRIC CHAIN HOISTS
Electric chain hoist of the YOYO range and the relevant electric traveling trolleys are
manufactured according to the concept of modular components which allow the
production of different executions, both standard and special. Base components, motor
and reducer, thanks to their extreme compactness are assembled to one another on a
coaxial line, so as to guarantee the maximum exploitation of the hook’s path as well as
the hoist’s minimum overall dimensions. They are manufactured using the most
advanced technologies which are based on highly industrialized production processes
and allow the production, through economy of scale, of totally reliable and technologically
innovative machinery.
The high quality standard is guaranteed and verified by the quality system certified
according to UNI EN ISO 9001:2000.

The machine should be placed under some kind of roof, in a well-aired, free from corrosive vapors (e.g. acid vapors, salty mists, etc.)
environment
Special executions for different environmental conditions or for outdoor operations may be supplied upon request.
NOISE
LEVEL
The level of acoustic pressure produced by the full load hoist is always inferior to 85 dB (A). The impact of environmental
characteristics such as sound transmission through metallic frames, reflection due to the combination of machinery and walls, is not
included in the above value.
