Air Conditioning Added To 30-Year-Old Trackhoe

Air Conditioning Added To 30-Year-Old Trackhoe TRACTORS Miscellaneous 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 ” Contact: FARM SHOW Followup Ron Heidebrink ph 843 756-7007; www double-alt com
