• Hydraulic system
Check the hydraulic system's working pressure.
The bin lift is specified for a lifting power of a
maximum of 500 kg.
-
Working pressure 4-wheel (coupled chairs)
200 bar
-
Working pressure 2-wheel (single chair)
90 bar
The lifting pressure of both lifting chairs is monitored
by pressure sensors. The lifting pressure can be read
off on the Diagnostic System (see chapter 3,
par. 3.11.2).
• Hydraulic hoses
Check the production date of the hoses.
-
The hydraulic hoses must be replaced after
4 years in service. This must be done at the
latest 6 years after the production date (shown
on the hose ferrule).
• Electrical wiring
-
Check the electrical wiring, electrical
connections and control stations for moisture
penetration.
• Springs
Check the springs of the lifting chairs and the
catcherbar.
-
As a precautionary measure, the springs must
be replaced after 500,000 cycles per lifting
chair.
The counter (optional) can be read off on the
Diagnostic System (see chapter 3, par. 3.11.3).
Any faults identified must be rectified before
the bin lift is put into service.
