15.9 Components in overload control system
Overload control system has been set to correct values at the factory. Changing of the
settings without permission and instructions from the manufacturer is strictly
forbidden. RISK OF TIPPING OVER!
Overload control mechanism is located between the
platform and platform mounting bracket, and is
accessible by opening the cover plate on the platform.
The platform is supported by a spring, located between
the limit switches. When load on platform grows, limit
switches cut off the power.
Measuring of load on the platform is doubled as follows:
limit switches S17A (1) and S17B (2) are adjusted to
lower SWL = 135 kg. Limit switches S18A (3) and S18B
(4) are monitoring the max. load = 200 kg.
If S17
– A or B – cuts off the power, movement of
telescope is restricted and <135 kg indicator (5) goes
out. If telescope has been extended and one puts more
load than allowed on the platform, there is an audible
warning signal and the indicator (6) starts to blink. In
the 135 kg overload situation the safety valve K9
remains currentless, preventing operation of booms.
Overload control system is reset by stopping the engine,
removing the overload from the platform and starting the
engine again.
If max. load on the platform is exceeded in any position of the booms, an audible warning
signal is heard both at platform and at ground level, the red indicator blinks and the
engine/motor stops.
ATTENTION! If the <135 kg indicator is not lit when boom operation is selected and the
green indicator for lifting the booms is lit with platform empty, and the <135 kg
indicator goes out when there is clearly over 135 kg load on the platform, operation of
the machine must be stopped immediately. Contact Leguan service.
NEVER EXCEED SAFE WORKING LOAD!
