Solenoid lock contact inspection:
•
The surface of the contacts on the solenoid interlocks has a finish of nickel. This
is applied to the surface and is subject to wear. If the surface is dull or rough, it may be
restored by cleaning it with a mild degreaser, alcohol, or window cleaner. Some
Technicians has had success using common erasers. However,
do not use abrasives!
If the contacts are pitted corroded or if the nickel finish has degraded, the lock must be
replaced. Cleaning the contacts may reveal the copper under the nickel. This is a sign
that the contacts are worn beyond repair.
Never bypass the safety circuits on a Genesis lift!
Inspection of the Slack Chain Safety Device:
The slack chain device on Genesis Hydraulic lifts is there to make sure any deviation
from the normal travel of the support chains during travel does not result in an unsafe
condition. Whether one or both chains are slack, this device will lock the platform in
position and prevent movement of the lift. Should this occur, the technician must resolve
the cause of the problem before returning the lift to service
The Safety device includes a locking system and an electrical cut out switch. The
locking system is spring loaded and depends upon the even tension of the ropes to
prevent two knurled teeth or “Dogs” from engaging onto the brake bar. Should anything
interfere with the chains, the dogs bite into the bar and stop downward travel. At the
same time, the electrical cut-out switch is activated shutting down the lift operation
completely.
The Genesis Hydraulic
safety includes two
knurled discs (dogs)
and a safety switch
(arrowed).
