Video Title: 48 Minutes Of High Flying Action At Dry Fork Station Video Duration: 2:52 From: pc2drth Category: Travel and Events we see trucks, bulldozers, forklifts and cranes at construction sites all the time. today, though, we get to see work at the dry fork station done with something entirely different a helicopter.
by using a helicopter to remove the items from the top of the chimney and bringing materials up, we probably save 3-4 weeks of time.
pullman power, dry fork stations chimney contractor, built the plants chimney stack using a hydraulic lift system. now, that equipment needs to be removed and the roof or rain cap needs to be delivered to the top of the stack.
before that happens, final preparations are made that includes a job safety annaysis.
all riggings inspected. all of our rigging is brand new nylon chokers on top and on the ground.
once the rigging crews are in place on the stack and the staging area, the pilots buckle in.
the helicopter lift is about to begin here at the dry fork station. the east half of the plant has been shut down to all road access as well as the railroad for about two hours while the lift is happening. the helicopter behind me is about ready to take off for its first trip.
doug ramsey: this will be the first pick off the top of the chimney. they are going to remove what they call the cat head. thats the eye beams that supported some of the structures on top of the chimney.
the support structures and strand jack system were used in the construction of the chimneys steel liner, which is inside the 500 foot concrete shell.
doug ramsey: theres, i believe, nine loads to be removed from the top of the chimney and then theres seven loads that will be hauled from the staging area up to the top of the chimney, which are the components for the rain cap, the roof section of the top of the chimney.
once welded in place, the rain cap will protect the stack from the elements.
as always, safety is top priority. the pilot and riggers on the stack are in constant communication during the lift.
i try and get him to bring it in towards me and i grab the tagline and well just kind of pull the taglines apart to keep them from spinning around and once you get it spun the way you want it to, ill just tell him, you know, down, down, down and hell just basically push it down in between the stack.
in all, this sikorsky helicopter makes 11 trips with 16 individual picks before landing.
after a month of planning and just 48 minutes in the air, the lift is complete. without the helicopter
we would have had to erect a gin pole and use a hoist to do it manually, which would have impacted contractors around the chimney. so, this was safer and much more efficient for us.
all the planning paid off.
the lift went fantastic. it was boring, which is what we shoot for.
the chimney stack is now 95 percent complete. pullman power just needs to weld the rain cap in place and finish the electrical work.
