A hoist or hoisting device is configure to place a pallet on a roof without the need of a person on the roof. The hoist includes a deflector that moves between a first position and a second position and releases a strap from an open hook as the deflector moves from the first position. A release arm on the deflector contacts a portion of the strap to push the strap off the open hook after the pallet has contacted the roof. The hoist may then be raised and the strap be unthreaded and pulled upward through the pallet to leave the pallet installed on the roof.
