Functional description
The
"transport platform"
operating mode (platform control) has to be
activated.
The platform operator has to activate the platform control at the key
switch on the platform control each time after entering the platform. For
confirmation, a green control light above the platform control also lights
up.
The
"Construction hoist"
operating mode (external control) is
automatically activated.
When leaving the platform, the "Construction hoist" (external control)
operating mode is activated automatically. For confirmation, a green
control light above the platform control lights up.
•
The machine is fitted with an overload detection device. If the load
capacity is exceeded, this switches off travel movement in both
directions and the red control light on the platform control
illuminates.
•
The lower safety area is specially secured.
-
The lifting speed of the platform is only about 12 m/min.
-
DOWN
travel is only possible using dead man's control.
-
When the platform is descending, it stops at the lower safety
area and, before starting in this area (
UP and DOWN
) a signal is
emitted for approx. 3 s.
-
Within this zone,
the hoist cannot be operated from the
landing level control
.
When using the 2.00 m base enclosure with sliding door, the lower
safety area is omitted. The platform can then be moved down to
the ground station using all controls.
•
The platform openings (barrier, door/ramp, assembly guard,
assembly plank) are electrically monitored and interrupt the safety
circuit when opened so that the platform immediately stops or does
not move off.
-
The access at the ground station can only be opened when the
platform is actually at the ground station.
•
The downward travel path of the platform is limited by a
DOWN
limit
switch and the upward travel path is limited by an
UP
limit switch. If
one of these limit switches is overrun due to a fault, the
EMERGENCY LIMIT
switch interrupts the
EMERGENCY STOP
safety circuit.
Further travel from the landing level limit switch is not possible in
either direction.
•
Installation of the construction hoist includes safety devices for the
loading and unloading points (refer to the assembly manual).
