Rigging the HP Discover Flip Door with a Pushstick Winch

Rigging the HP Discover Flip Door with a Pushstick Winch

For most who attended HP Discover in Las Vegas this year the appreciation was on the technology showcased for business and government customers. But let’s not forget that a dramatic entrance, such as the flip door used by  HP CEO Meg Whitman, had some fun technology of its own.

Our friends at Production Plus built the door and tasked us with rigging the automation for it. Much like the progressively detailed studies an artist develops before the final painting is created, the flip door rigging saw its share of iterations, three to be precise. You can see each one in this video, and read more about them below. And yes, that’s Herbie Hancock’s 1983 “Rockit” in the background, just for fun.

The first wooden mock-up came together quickly and established the core design to meet the criteria. In that design we decided to use a Pushstick winch to raise and lower the door, rather than mounting a motor at the hinge which would have required a custom machine. By using the winch and rigging the door exclusively to the surrounding wall they built, we saved both time and money.

Built and rigged in a day, the wooden mock-up showed that a winch line would nicely raise and lower the door, even if the orientation did give it a rather drawbridge like quality.

The second mock-up, also built in a day,  grew to full size, sported a steel frame, and brought into the design two critically placed sheaves. Our Turnaround Sheave took the lines from the winch and guided them each to a custom sheave which changed the line in two directions. These three turns of each line precisely positioned them to lift the door with as little friction as possible.

With testing complete at our shop, it was time to pack Royal and the rig for Production Plus’ shop outside of Chicago to test it once more on the actual flip door. By automation rigging standards, it was a relatively simple packing list: Stagehand ACTurnaround Sheave, custom sheave, cables, power distro, showstopper, turnbuckles, toothbrush, toothpaste, and PLSN to read on the plane.

A similar process took place outside of Chicago. And when we say outside, we really do mean al fresco. The flip door and its companion wall outgrew the shop space and required set up in the parking lot. Once the wall was built, only fifteen minutes was necessary to mount the sheaves, run the cables, adjust the turnbuckles, and connect the winch & electronics. With a beautiful Midwest sunset for a backdrop and a fork lift bracing the wall, the flip door rigging looked good. Time to pack for Las Vegas.

Stunningly vast and cavernous, the Venetian Palazzo auditorium was transformed into a dynamic and inviting space for thousands to celebrate all things HP and IT. As in the previous shop set ups, Royal attached the pulleys while the wall flat, then rigged the rest after the wall was up. Flip door opened smoothly. Flip door closed smoothly. No problems.

Royal remained on site to run the automation during the show and was able to offer advice on a mobilator giving Production Plus some problems. He adjusted it to run more smoothly and also operated it during the show. It’s handy to have an automation tech in the house.

Many thanks to Doug, Duane and Jacob at Production Plus. We were happy to be involved in bringing the HP Discover event to life. Let’s keep makin’ it move.
