ELECTRIC WINCHES TO KNOW
In lifting In pulling application application Limit switch Mandatory Optional Fitted pulley Possible up to 1.5
t .
Recommended (possible up to 1.5
t) .
Centrifugal brake - Optional (only available for the
INDUSTRIA
range) .
Secondary security brake - Compulsory for stage equipment D8+C1 .
Rope slack switch Optional Optional Electronic load limiter Mandatory from 1 t .
As per
NF EN
14492-1 : 2016 standard , compulsory in some case : check with us Limit switch Clock type : specially designed by Huchez with 2 positions .
This easy to adjust system provides security by preventing upper and lower overruns .
Secondary security brake Rope slack switch This option increases the safety This devise automatically stops lifting level .
It is mandatory in the winch when unwinding if applications related to stage the wire rope is not tensioned .
equipment , people lifting and For example : when lowering load lifting above people (here and the loads meets an obstacle with a cam type limit switch) .
or in traction .
Limit switch Cam type : 2 , 4 , 6 or 8 positions possible .
IP
66 .
Encoder option also possible .
Fitted pulley Centrifugal brake The pulley with effort detection It controls the lowering speed electrically cuts the winch as soon in case of failure of the motor as there is an overload .
(Up to or the automatic brake .
25% above the nominal load) .
The devise acts as a simple switch .
(see p .
93) .
Electronic load limiter This devise stops the winch in case of overload without breaking the kinematic chain .
It is mandatory in lifting from 1000 kg (Directive 2006/42/ EC) to avoid cable breakage , structure deformation and therefore accidents resulting from problems due to overloads .
x Security options According to Machine Directive
MD
2006/42/EC , are mandatory on electric winches : The emergency stop , The limit switch (in lifting) , The load limiter (from 1 t) .
