DANGER !
If for any reason you are unable to lower the lift completely onto the drums,
stop immediately and consult the factory at 888-811-9876. Failure to use a
system of adequately stable and strong lift blocking devices could result in
severe injury or death.
II. BLOCKING FOR EMERGENCY REPAIR or INSPECTION
Whenever the carriage has stopped at any elevation besides the fully lowered position
and will not move using the operator pushbutton stations, the carriage must be secured
against downward movement prior to beginning any inspection or troubleshooting
activities that require the gates/doors to be open.
In particular, a carriage which has become wedged in the guide beams, or has become
jammed by interfering with surrounding structure (landings, floor opening, door headers,
backstop assemblies, etc.), may have damaged or broken the lifting chains or other
critical components that are supporting the carriage. Therefore, when a carriage
becomes wedged or jammed DO NOT walk out onto the carriage or attempt to
physically free the carriage until the carriage has been adequately supported from
beneath.
In any of these emergency conditions, safe lift blocking can be accomplished using one
of these approved alternate methods while following steps I.1 through I.5 above:
1. Use a series of adequately sized adjustable jack stands around the underside
perimeter of the lift carriage to provide a level, stable support
2. Use a fork truck with adequate travel, capacity, and fork width/length to provide a
level, stable support
NOTE: Whenever a wedged or jammed carriage condition occurs, you should call an
authorized Autoquip dealer or representative to conduct a comprehensive inspection of
the lift for structural and component damage before placing it back into service.
