Abstract

A door opener for a roll-type door in a cargo van includes a shaft that is mounted for rotation within the cargo van body and is coupled with the door such that shaft rotation causes the door to move between opened and closed positions. The shaft is rotated by a motor that is mounted outside of the cargo van body and is coupled to the rotatable shaft by a drive system that extends through the cargo van body. This arrangement allows a relatively large conventional motor to be used without extending into the door opening or compromising the height of the door opening.
