CAMA Gets a Corliss Steam Engine
Part 3 - Picking the engine

In order to lift the steam engine out of the building (the pick), a hole had to be cut in the roof over the engine. The hole had to be large enough for the frame to fit. The hole was centered over the flywheel, meaning that lifting the flywheel halves and the crankshaft would be a straight, centered pick for the crane. This also meant that the engine frame, the heaviest piece was NOT centered under the hole.

The roofing is a corrogated steel over trussed space girders. On top of the steel lies a layer of fiber insulation and a rubberized membrane.  The heaviest piece of of the engine is the main frame at about 8 tons.  A crane can only get to about 35 feet from the opening in the roof, so a 60 ton crane was needed to lift that much weight at that distance from the crane.

John and Michael Luchesi and a crew from Barrett Roofing volunteered time and materials to remove the old roofing,  stripping down to the steel a few days before the crane is scheduled to arrive. CAMA volunteers assisted in removing the roofing.

The corrogated metal roof from the inside. The area marked with the large holes is the roofing to be removed. The middle section of girder must also be removed.  Everything is now ready for the crane and the pick. The roofing is left in place as a safety measure.

On Saturday morning (Dec.15, 2006), the day of the pick, the corrogated metal roofing is removed using a Saws-All to cut through the rusty steel.

Once the roofing is off, the various angle iron and barstock pieces spanning the hole are torched. The central girder awaits the crane to lift it out after cutting.

The Arnoff/Alantic Coast Moving & Rigging crane arrives on schedule. After setting up, the crane is first used to lift replacement steel roofing to eventually re-cover the hole. The crane is then used to lift out the center girder shown in previous photos after Ray cuts it loose with the torch.

The riggers from Atlantic Coast prepare the top half of the flywheel for the pick.

Once the top half of the flywheel is secured with straps, the bolts holding the halves together are removed.  The piece is soon up and on its way to the flatbed trailer.

Now, the lower half of the flywheel, supported on the wood cribbing, is lifted out of the engine room.
ABOVE:
The engine frame is not centered under the hole in the roof, so a combination of a chain hoist, strapping and and heavy duty rollers (the red items under the pedestal of the frame) are used to carefully roll the frame under roof opening prior to lifting.

Now centered, the crane can pick the engine itself.  Note the chain hoist used to level the engine during the lift.

The ~8 ton engine appears to be floating over the hole in the roof.

The engine frame is set down on the flatbed along with the other parts of the engine. The flywheel halves are visible in the foreground.  The crankshaft is the last piece of the engine to be placed on the flatbed. The pieces are all securely strapped down for the trip to Kent on Sunday.

The final step on Saturday is to police the worksite, and close the hole in the roof to prevent unintended injury.  Even though the mill is scheduled for demolition, CAMA was committed to making the work site as safe as possible to prevent injury once we have left.

Thanks go out to the crew of volunteers from Barrett Roofing
Thanks also go out to Arnoff/Altantic Coast Movers & Riggers for a trouble-free pick.
