Endwall Derrick

The endwall derrick is a permanently installed tripod

device of galvanized structural steel. In service, removable structural aluminum tracks are positioned across the platform opening. Equipment to be handled is placed on a 4-wheel dolly—part of the equipment handling package—rolled onto the track and elevated slightly. The track and dolly are removed and the equipment lowered to grade level. With single sheave rigging, the derrick will handle loads up to 3000 pounds—the weight of a large Geareducer—normally the single heaviest component in the mechanical equipment package. Cable and power for rigging are not normally provided by SPX.

Endwall Davit

The endwall davit is offered for Class 600 towers equipped with smaller Geareducers (Series 27 and smaller). This galvanized steel hoisting device is permanently installed at a corner of the fan deck and is rated for a load of 1000 pounds with single sheave rigging. The rotating arm is mounted with protected ball bearing joints for easy travel under load. Reach from centerline of the vertical post to the hook-eye is 6′-0″. Clear height from fan deck to the hook-eye is 8′-6″. Removable guard and knee rails are installed at the landing point. Rigging apparatus is not normally provided by SPX.
