Warning in case of breakdowns
If a ramp cannot be repaired immediately in case of break-
down, it must be put out of operation and secured against
unauthorized use.
A ramp put into storage position with the help of external
devices (forklift, gantry crane,…), is not supported by its hy-
draulic cylinders. After releasing the mechanical platform
lock, the platform and lifting mechanism will drop in free fall
to the start point of the breakdown, without any possibility to
stop the fall by means of the regular control box. This can
result in the ignorant operator and third parties being at great
risk. [see Fig. 4.14]
To avoid any risk, close the mechanical platform lock and
apply additional means to immobilise the platform (eg. by
additionally securing the original platform lock, by means of
ratchet straps,…). Signal the hazard in a clearly visible way.
To re-open the ramp, use again an external device (forklift,
gantry crane,…) for additional support. Or repair the break-
down first, bring the hydraulic system under pressure, and
release the platform locks after satisfactory testing of the
ramp functions.
