QUICK-RELEASE ROLL-UP SYSTEM FOR TRAILER

摘要

A tarp deploying apparatus includes an electric motor attached to a radial arm. The electric motor provides rotational force to a tarp roller through a planetary gear transmission. The electric motor can be taken out of engagement with the gear transmission by a quick release lever. A second radial arm at an opposite end of the tarp roller includes a support member that supports a splined end of the tarp roller. The splined end is adapted to be engaged by a hand crank to permit manual rotation of the tarp roller by the hand crank when the electric motor is out of engagement with the gear transmission.
