Stop working immediately if defects occur during opera-
tion. 

All type and instruction plates must be fitted and legible. Any missing or no 
longer legible type and instruction plates must be replaced immediately!

Wire ropes must be replaced immediately if a defect 
according to DIN15020 sheet 2 or ISO4309 has been 
detected during the weekly check: 

–  more than 11 broken wires over a length of 24 cm (dia. 8) / 27 cm 

(dia. 9) / 30 cm (dia. 10)

–  Strong formation of rust on the surface or inside 
–  Heat damage, indicated by burning discoloration 
–  Reduction of the outer diameter to less than 7.6 mm (dia. 8 mm) / 

8.5 mm (dia. 9 mm) / 9.4 mm (dia. 10 mm)

If damage is detected on the insulation or on the cable connections during 
the weekly check of the electrical cables, replace or repair supply and 
control cables immediately!

B) Safety check by a competent person 

A 

competent person

 has been enabled to carry out 

safety checks

 on 

Yale winches for passenger elevation and Yale safety locks by adequate 
training at the manufacturer’s.
Safety checks of Yale winches for passenger elevation and Yale safety 
locks must be carried out at least once a year by a competent person.
Exceptional ambient conditions or conditions of operation may require 
additional safety checks according to the relevant accident prevention regu-
lations for “Hoists, lifting and towing devices” (BGV D8) and the standard 
“Safety requirements on Suspended Access Equipment” (DIN EN1808).
