Why APPI:  Testing an aircraft engine assembly is a critical operation required to approve an aircraft for flight.  Due to their size, weight and movable parts this work is always a challenge and that challenge increases when the testing must be conducted in remote locations without shore power.

After being contracted to build a trailer for this purpose, Michael Knight, president of Knight Aerospace, turned to APPI for assistance in configuring an engine test stand hoist to meet the requirements of this application that could operate off the DC power source on the trailer.  It also needed to be capable of operating on a continuous duty basis as well as be equipped with an electrically released, load holding brake.

We determined one our Columbia HR3G hoists equipped with a 1 HP continuous duty DC motor and brake with the drum grooved for 12mm diameter wire rope was the correct choice for this for this application.

Michael came to us for assistance three years ago on a similar project with a different type of hoist.  We are glad we were able to help him again with this custom test stand hoist.
