Altitude
Multiquip does not publish a derate figure for the DCA line — not on the data sheets, not on the product pages, and not in the manuals we could reach. We are not going to invent one. What Multiquip does publish is the engine: this machine runs a Kubota D1105.
That is a naturally aspirated engine, and naturally aspirated diesels lose real output as air thins — the losses become significant above roughly a mile, which is where most of our customers work. Size this one for the elevation it will actually run at, not for sea level.
We are at 6,035 ft in Colorado Springs and we sell into sites well above that. Tell us the elevation and the duty and we will get the derate in writing from Multiquip before you order, rather than after.
