Description of function
The
GEDA 500 Z
is a vertically installed rack and pinion hoist which is
used exclusively for transporting scaffold parts, objects and construction
material.
•
The base unit can be extended using 1.5 m-long mast sections up to
a maximum installation height of 50 m (230 V) or 100 m (400 V).
•
Complete installation of the construction hoist includes safety
equipment for the loading and unloading points (refer to Chapter 6.4).
−
The danger zone, excluding the access point to the platform, must be
cordoned off and identified.
•
The load bearing capacity is max. 500 kg.
−
The machine is equipped with an overload device that switches off
travel in both directions when the load capacity is exceeded; a red
overload warning lamp lights up on the trolley switch box.
•
With a
230 V drive,
the hoist lifting speed is approximately
8 m/min.
or 13 m/min.
and with a
400 V drive
it is approximately
30 m/min.
•
The lowest 2 m are specifically secured.
−
Travel is only possible using dead man's control.
−
A warning sound is emitted when
travelling UP
and
DOWN
.
−
Within this range, the hoist cannot be operated from the landing level
control.
•
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.
•
The turned platform interrupts the safety circuit. The hoist is unable
to start with the platform pivoted.
•
Using the key switch on the assembly control (in the platform), this
control (key remains inserted) is switched to the external control.
−
Operation of the external control is carried out using the ground
control outside the danger zone - or from the electric modules of the
landing when above the 2 m safety height.
−
Automatic operation is possible above the 2 m safety height.
•
The platform opening (ramp) is electrically monitored and interrupts
the movement in both directions (
EMERGENCY STOP
– safety
circuit interrupted).
