INSTRUMENTATION
The AUTO CRANE hydraulic drive compressor unit incorporates a gauge panel that monitors
temperature, pressure and hours of operation.
HOURMETER
The hourmeter records the total number of operating hours. It serves as a guide in following the
recommended inspection and maintenance schedule. The hourmeter will only run when there is pressure
in the system.
COMPRESSOR DISCHARGE AIR/OIL TEMPERATURE SWICHGAUGE
This swichgauge indicates compressor air discharge temperature. The swichgauge ensures safety
shutdown in case of excessive operating temperatures, preventing compressor damage, by stopping
hydraulic flow to the compressor motor.
ELECTRICAL AND SAFETY SYSTEM
The AUTO CRANE compressor's standard electrical system consists of:
-Gauge panel with a temperature swichgauge, hourmeter and discharge pressure swichgauge.
-Compressor and hydraulic oil cooler fan assembly and relay.
-Compressor after cooler/oil cooler fan assembly with relay.
-N.O. hourmeter pressure switch.
-N.C. blowdown pressure switch.
