3 Technical description
3.1 Description of function
The GEDA 200 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 with 1.0 m and 2.0 m long ladder
sections up to a max. installation height of 41 m.
• Complete installation of the construction hoist includes safety
equipment for the loading and unloading points (refer to Chapter 5.5).
− The danger zone, excluding the access point to the platform, must be
cordoned off and identified.
• The load bearing capacity is max. 200 kg.
− The machine has an overload device that disables movement in both
directions if the payload is exceeded. If switched off due to
overloading, a red warning lamp on the trolley switch box illuminates
and a alarm signal sounds.
• The lifting speed of the hoist is only approx. 25 m/min.
• The downward travel path of the platform is limited by a DOWN limit
switch and upwards by an UP limit switch.
• The turned load platform interrupts the safety circuit. The hoist is
unable to start with the load platform turned.
• Control is carried out using the ground control, from outside the
hazard area.
− The ground control is a mobile manual control plugged into the
switch box of the foot section. For installation purposes, the manual
control must be fitted with a special extension lead for this manual
control.
• The platform opening (loading ramp) is electrically monitored and
interrupts the movement in both directions (EMERGENCY STOP
safety circuit).
