Air Conditioning Added To 30-Year-Old Trackhoe
 ✖  |
Ron Heidebrink says the cab of his 1988 trackhoe was so hot during the summer that even opening the windows and using a fan wouldn’t cool it enough to make it comfortable. He solved the problem by installing an air conditioning unit from an old motor home.
“The cab had a flat roof that was large enough to bolt the RV air conditioner unit in place, but the trackhoe’s electrical system only had 28-volt DC power, which wasn’t adequate,” Heidebrink says. “I solved that problem by installing a larger 28-volt electrical system and an inverter to create 110-volt AC power.”
His installation included replacing the original trackhoe alternator with a double alternator to improve the electrical output. Now he’s able to use a 110-volt electric heater, too.
“Using the double alternator and the inverter made it possible to use an RV roof unit and install it myself without the need for a licensed AC installer,” says Heidebrink.
He is a retired engineer and pilot and actually invented the double alternator in 2007 (featured in Vol. 43, No. 3). “It’s a great device that can be used with any size batteries, providing high amperage while the motor is idling.” It installs on the same brackets as the existing alternator and uses the same belt or belts.
“By installing a double alternator and an inverter, any older tractor, combine, truck or road equipment can use an RV air conditioner,” Heidebrink says. “You can also plug in a grinder, trouble lights or anything else that runs on 110 volts.”
