Uplifting Marjorie Prime

Last month’s production of Marjorie Prime at Center Theatre Group featured some pretty heavy lifting under the set. We were happy to provide the automation for that heavy lifting, and coordinate with our good friends at Stage Machines for the hydraulic muscle. Center Theatre Group is no stranger to automation, and have used their Fisher (FTSI) gear regularly. However, the automation in Marjorie Prime would require hydraulics, and that could not be controlled easily with the FTSI gear they own.

Mimi Lien’s set design (a stark, “soul-erasing beige”, assisted living facility 50 years in the future) requested the automation of one large stage platform (traveling 42″), a sinking refrigerator, and a small sliding set of steps. No problem. In the video you’ll see our initial scissor lift mock up, testing at load-in, and the full set in motion. Read on below the video for further description of the process.


The gear line up:
Four scissor lifts
One 10 hp hydraulic pump (that’s right just one)
One custom 10hp drive
One flow divider
One small hydraulic scissor lift
One small pump
One Stagehand Mini
Two Stagehand AC Motor Controllers
One PC laptop with Spikemark installed
Celesco and Unimeasure Encoders
Cables as necessary

After a site survey in sunny Los Angeles at the Mark Taper Forum, the next step was to tackle the largest component, the vertical automation of the stage platform. Working with Stage Machines, we decided to do a mock up of the design for a piston flow divider consisting of one master cylinder and four slave cylinders that could be controlled by a single Stagehand Mini.

With one piston doing the work, and the other pistons mechanically joined together, the exact amount of oil would go into each lift’s cylinder to produce completely level lifting and lowering even though the weight of the platform would be unevenly distributed. Satisfied with the results, production began on those components.

For the sinking refrigerator, a small hydraulic scissor lift powered by a Stagehand AC was placed beneath the unit. And the sliding steps were rigged to an existing FTSI winch controlled with a Stagehand AC and some help from a custom set of adapter cables.

All the gear was shipped to and installed by Center Theatre without problems. Nice job, everyone!

Special thanks to Assistant Production Manager Kate Coltun, Stage Carpenter Emmet Kaiser, and Assistant Technical Director Chad Smith. We’re looking forward to working with you again!

share your automation, #makeitmovecci

Let’s face it, automation is cool. It’s okay to brag. We won’t judge. We know you do amazing things with our gear (it’s why we we make it, after all).

So why not share what’s moving on your stage, tag it #makeitmovecci on Instagram and let us send some free swag your way.

The Monster Tour Raises Standard for Hydraulic Lift Control

In his May “Songs to Spectacles” article for the Washington Post, Steve Knopper gave a wonderful prologue to the summer concert season, summarizing the humorous and humble beginnings of the modern concert special effects industry. From the 1980’s antics of rigs with forklifts and “delightfully primitive…old-fashioned levers” to a full take over this century by “computers and robotics”, Knopper suggested this year’s season was poised to “blast into high gear with the latest and greatest in digital innovations.” It’s as though he knew we would do something awesome with computer controlled hydraulics.

Our friends at All Access Staging Production in Los Angeles were eager to up the ante in their control of  hydraulic lifts on The Monster Tour (Eminem / Rihanna).  Controlling hydraulics with a computer can be tricky, but with our own latest and greatest controller, the Stagehand Mini2 (that’s “mini-squared”), we were able to offer them reliable repeatability, and easy synchronization of three hydraulic stage lifts as well as two tracking video walls. In total the lifts would be used roughly 12 times during the 50-song show, amassing more than 20 cues including video wall movement. “The Monster Tour” opened at the historic Rose Bowl on August 7 to wildly positive reviews, and the show itself opened with Rihanna rising first on one lift, then as profiled on billboard.com, Eminem emerging on another lift “strapped to a stretcher à la Hannibal Lecter.” Those crazy kids.

It all happened rather quickly. The three-city tour lasted just two and half weeks in August (although it was able to entertain almost 250,000 fans thanks to the massive venues.) We ourselves only had three weeks of preparation for our part in the stadium scale production designed by Tribe Inc. to “match the epic nature of [the] two iconic artists.”  Our task was to control the two 4′ x 8′ platforms (each comprised of two stacked scissor lifts) which could completely collapse below stage level or elevate 6′ above. From the same computer screen, the automation operator would also control two 8′ x 24′ tracking video walls.

Debuting our Mini2 on this job, we took full advantage of its programmable outputs which give it a versatility well matched to the nuances of hydraulics. For example, since there would be six scissor lifts in this production, each set of two would only require a single case with one Mini2 and two valve power supplies. And the entire six lift system would only need one pump.

When we aren’t using our open shop space for corn hole or pallet jack skating, we routinely build, rig and run numerous automation set-ups for both custom and stock products. Nailing the specifications of this hydraulic job required just that. We borrowed a single acting scissor lift and old Feller Precision proportional valve from our local buddy Stage Machines. Although none of the parts in this test rig except for Spikemark control software would be the actual components in the tour, it did show that we could meet the technical spec of the job, namely that a proportional valve could be used on a single acting lift all connected back to our Spikemark control software.

After testing was complete, the Mini’s along with the other components were speedily built and shipped to the All Access shop in Los Angeles for their shop test. At this point, although the units had shipped, and Gareth himself was about to get on a plane bound for L.A., a problem arose that was easily corrected thanks to some key features of the Mini2. The necessary addition of a solenoid locking valve programmed to fire when the lift speed approached zero was merely plug and play due to the Mini’s auxiliary outputs and ability to have firmware changes made via Spikemark. Really, it’s like the Swiss Army knife of automation controllers.

Gareth’s travels to L.A. insured the shop test of the lifts went well, and he returned to L.A. the same week not just to keep racking up those frequent flyer rewards, but to assist with on-site cueing after the lifts were loaded into the rehearsal space at the Sports Arena. Taking advantage of the proximity to our Rhode Island shop, he and Royal later joined the crew for their NJ shows at MetLife Stadium. They offered back up as well as direct support for the automation operator. Again, the show was executed very well. Video walls tracked, lifts glided up and down, and of course there were pyro, lasers, smoke machines, and very talented musicians anchoring the entire production.

We were pleased to offer our technical assistance with the motorized video walls and stage lifts, all moving at the push of a button with an accuracy to .050″. Contributing to a part of the visual extravaganza at a Rock-and-Roll show reminded us how spectacle bolsters the music and the artists in a way that heightens the entire experience for the audience. Specifically heightened to 6′ above the stage on hydraulic platforms.

Many thanks to All Access for inviting us!
