Cat 315 D Pump functionality

Tomi Vartiainen

I have a general question about Cat 315 D, but it involves other Cat excavators also.

About the hydraulics of the machine, is the main hydraulic pump turned on only when something is done (eg. the cabin is turning or arm is moved etc.)?

Background is that I want to remotely know, when the the excavator is working, doing actual work, not just standing there running idle. I need some electrical interface for it, meaning that some component is turned on, when the unit is actually working, and status of that is monitored (voltage present or not).

I was wondering if this could be done when the on/off-status of the hydraulic pump is monitored vai external tracking box, which solution I already have. I'm not an expert on excavators nor their basic functionality, but if the pump is turned on "on demand", that would be the solution. If it is always on, even thou the machine is doing nothing, I must find another solution, which You may help me of course too! :)

Cheers,
Tomi

When the engine is running the main pumps are turning but, the swash plate is at minimum angle so there is no output. The pilot pump will have a constant output when the engine is running and none when its not.

Cat does have "product link" With this you can monitor all the machines functions and status remotely from the internet, track where it is with GPS and receive emails when it does something outside those parameters. this option cost money and so the bigger companies only seem to use it.

You could use a pressure sensor in the hyd system to know when the hydraulics are being used.
