11. EMERGENCY LOWERING
If the power supply for some reason cuts off (e.g. no fuel or electricity cuts off, or connecting
cable fails) the booms can be lowered as follows:
1. The lift is equipped with an electric emergency lowering system. There are emergency
lowering buttons both on the platform and at ground level (p. 15, picture 5 and p. 17,
picture 9). By pushing the button the selected boom comes slowly down as long as the
button is being pushed. Emergency lowering takes it power directly from the battery
–
it is not dependent on the position of the main switch. Emergency lowering valves are
protected with a 10A fuse which is located in the connection box on the side at ground
level.
2. Before lowering the booms to transport supports always make sure that they are
properly aligned and going straight down to transport supports. If necessary, the
booms can be rotated at the end of the slewing ring shaft either with a 22 mm key or
with a socket wrench or with the crank that is located on top of the emergency
lowering controls box at ground level. Switch off main current before rotating the
booms manually.
ATTENTION! Always remember to remove the tool after rotating the booms. Never
rotate the slewing ring by hand when the engine/motor is running and the main current
is on!
Always check function of emergency lowering before starting operation.
