Trussing

The Companies

Tomcat
Bon Jovi kicked off the European stadium leg of their Bounce World Tour in Eurfurt Germany on May 25th with a new stage design. The satellite dishes from the first US leg have been retired, and the stage now features a moving high resolution video screen, along with three bands of fixed low resolution video across the complete width of the stage. The new stadium stage design was created by Doug 'Spike' Brant. The video screen was provided by Nocturne Video, and the specialized video screen support system was designed and manufactured by Brilliant Stages and Tomcat UK - both subsidiaries for Tomcat Global.

For their part, Brilliant Stages designed the vertical tracking system to support the six sections of moving high-resolution video screen. Four towers and a header truss pick up the screen sections which are arranged 3 wide by 2 high. The towers transfer a portion of the weight of the video screen down to the stage to avoid overloading the roof steel, and the header truss carries the hoists and drives during transit. Removable wheel units pin to the existing video screen frames and capture the DS tower chords. The screens pass within 15mm of adjacent columns while moving at up to 9.8mpm (32fpm) lifted by variable speed chain hoists under computer control. The customized CM chain hoists and metal fabrication were supplied by Tomcat UK. The system was designed to keep the setup and operation of a complex system tourable. The experience and capabilities of Brilliant Stages and Tomcat UK came together again and produced equipment to support a very impressive show. Following the last gig on the European tour in London, the equipment travels across the Atlantic in time to open the final US leg in Chicago, IL on July 11th.

prolyte
"Never trust a manufacturer that says the truss can be trusted if he cannot prove this with hard facts and adequate product information. Never trust information that only tells half the story. The safety of your truss is a matter of clear product information and compliance to ruling regulations." So says Prolyte when describing the wealth of information which accompanies their range of trussing products.

"Prolyte is very open and detailed about all the facts on their truss, whether it is calculation methods, product specifications, certificates or loading tables. All of the facts can be easily found and we are clear about what we show and how it was done. Not because the TUV logo looks nice in our brochure, but because we have a serious belief that safety comes before commerce."

Putting safety first has led to a strong feeling of trust in the company's products and innovative technical solutions. Prolyte has built a solid basis for growth; putting safety before sales figures, building on client trust, inventing technical solutions that really work, sharing information with their users with an open mind for criticism and change. Their 'Technical Edition 2003' gives more information on truss safety and is available through the company's website

Outboard
Out Board's CM-Series Motor Control distros for CM chain hoists have been purchased for a variety of applications in the current 2003 season's touring and events. Star Rigging have acquired three units of the compact CM12 twelve-channel controllers to manage 28 axes of CM Lodestar hoists deployed on a massive 200ft x 40ft 'flying stunt support truss' designed by Phil Broad and Gavin Weatherall for veteran boyband Westlife's current arena tour Unbreakable. The structure comes complete with I-beams along its length and breadth, used to float a substage out over the audience during the performance. Star also purchased two CM6 six-channel controllers for rigging duties at the Albert Hall book launch of 'Harry Potter and the Order of the Phoenix' in June, followed by Party in the Park in London's Hyde Park.

james thomas engineering
James Thomas Engineering custom designed and built a spectacular integrated stage set for the touring version of 'Cliff The Musical' - a colourful, light-hearted musical journey through the career of one of the UK's most successful artists. JTE was approached by Darren Wring of Bristol-based Fineline, suppliers of stage set and lighting to the show's production company That'll Be The Day. The set idea was initially conceived by Charles Cusick-Smith and Phil R Daniels. When Wring came onboard, he helped evolve it into a tourable structure, and turned to JTE for the construction. He worked closely with JTE project manager Pat Lockwood, and together they produced an aesthetically pleasing, highly practical set designed specifically for the tour.

The set contains all major physical elements of the show - band, entrances & exits, specific lighting positions, scenic guitar frets, projection surfaces, performance areas, etc - in a fixed area. It had to be flexible enough to adapt and work in a series of very different venues, including the Prince of Wales Theatre in London during its popular West End run. The set's superstructure is a huge platform 8 metres wide by 3 metres deep, with a curved roof extending up to 7 metres, high made from trussing arches. A 13.5 metre truss beam runs lengthways across stage, forming the set's 'virtual' ceiling.

Upstage is a set of 5 robust revolving aluminium scenic doors, used for entrance and exit points by the cast. When shut, these double as a projection surface. With the doors used extensively by the cast, clear 'rat run' access was needed behind them, so the structure is braced from back to front rather than the more conventional right to left, or via diagonals. The band are located in an elevated upstage area above the doors, complete with inbuilt acoustic shields, and the set also contains two ground-supported arched trussing side stage entrances.

doughty
Doughty Engineering of Ringwood Hants, has just launched a new range of versatile and economical lighting hoists. Although extremely lightweight , the new hoists can handle loads of up to 140kg. Their minimal 'closed height' allows for installation in studios with limited headroom or alternatively to give maximum overhead working height when stowed. By adding one or more pantograph to the system, maximum flexibility and control of individual luminaires on the barrel can be achieved. Since the hoist will accept programmable position control, studio time savings can be considerable. A full range of socket plates is available to suit indiviual requirements, including DMX, and the units will take either flat form and/or round cables. A full range of roof mountings can also be supplied.

summit steel
Summit Steel rigged twenty four-metre diameter inflatable footballs, thirty metres above the pitch at Manchester United's Old Trafford football ground for the all-Italian UEFA Champions League final between AC Milan and Juventus. Summit was asked to realise this feat - a world first for objects to be flown above a football pitch during a match - by their clients Production Team, led by Dave Keighley. The project was co-ordinated for Summit by Ken Nock. Summit used catenary technology, a method they've pioneered and perfected in the past, including at the M2002 Commonwealth Games. The starballs, each weighing 20 Kgs, were suspended in four-strips-of-five, each row attached to a 240 metre length of catenary wire running lengthways down the stadium. The catenaries were anchored to the main supporting structure of the venue's roof stands.

Summit worked alongside two sets of structural engineers - their own (Graphics Applications from Mold, North Wales) and Old Trafford's (Roscoe Capita from Cheadle Hulme, Cheshire) to perfect a plan whereby the starballs would have the dramatic illusion of floating in the air. The catenaries were pre-rigged the week before the event. As the starballs - made by Air Artists - only stayed fully inflated for 24 hours at a time, they were suspended overnight before the event. The wires were dropped in and Ken Nock and his team of 9 Summit riggers battled torrential rain and high winds to get the balls in place.

chainmaster
Via its North American distributors, Show Distribution of Canada, ChainMaster has just delivered 32 VarioLifts and 58 chain hoists conforming to the German safety standard BGV D8 along with a computer-based controller to the renowned Hofstra private university on New York's Long Island. The onsite installation was performed by one of Show Distribution's local partners. For nine years, ChainMaster has been manufacturing stage chain hoists and chain hoist controllers in Germany. Today the range includes chain hoists for loads from 125 kilograms to twelve tons. The most important factor in the success of ChainMaster chain hoists is their combination of control systems tailored to the practical requirements of users with the ability to reproduce movements precisely.

The Motor Positioning Control System developed by ChainMaster heralds a new era of precision, safety and ease-of-use in the control of chain hoists. It is a PC controller complete with the requisite software, which, being modular in design, is suitable for an extremely wide range of applications. Even in the standard configuration, the controller is equipped with a range of functions including the positioning and monitoring of electric chain hoists, electric running gear, curtain systems, light suspension units, backdrop hoists and cable winches. Various options are available such as path-and time-synchronized traversing, positioning with incremental or absolute encoders, networking and load-monitoring systems.

stage technologies
Like most pop groups of their kind, the UK band Westlife are known for their adventurous stage shows. The recent Unbreakable: Greatest Hits Tour, themed around different concepts of heroes, is proving even more amazing than most with the band flying right above the heads of the audience on a moving platform.

To produce these hi-level automation effects the Rigging Partnership - the company responsible for turning initial artistic concepts into a workable production reality - turned to automation specialists Stage Technologies. "The Rigging Partnership has bought together some of the best suppliers in the industry, proven technology and a dedicated team of riggers and engineers for this tour, the result is impressive."

Their 2003 solution was to installi a 1000 kg patented BigTow with two tracking motorswinch to fly the stage out nearly two hundred feet over the venue in a traversing action. Consultant and design engineer Mike Barnet worked with Gavin to develop an anti swing devise to ensure the stage stayed steady for the band to perform.

total structures
Two classic shows, Cats and the Lion King are this year touring Japan and, for the second time in as many years, Total Structures have supplied the equipment to make it possible.

The Cats tour will visit Shizouka, Miyagi and Hiroshima and Total Structures have supplied a large trapezoidal ground support grid, motors and control for the show. The grid will be placed in the audience area where the load bearing capacity of the existing roof structures was found to be inadequate to hold the weight of the lighting equipment. The grid measures approximately 100 by 40ft and is supported on six 20.5" square towers which comprise various length sections to cater for the stepped floor of the theatres. The tower sections are connected with the award winning Omni Connector to produce high axial and bending capacity towers. The main trusses are all supplied with runs of catwalk to facilitate access throughout the large grid.

The grid has a trim height of 45ft and includes an integral follow spot platform hung beneath the grid. A large amount of bracing has been included to resist the lateral loads which may be imposed in the event of an earthquake as determined by Japanese seismic standards. However, the steel wire rope bracing is not allowed to extend to ground level as this would interfere with access for the considerable amounts of scenery that are required to be moved on and off stage during the shows. The plan dimensions change for each venue and hence flexibility in the design was important.

The deflection of the main stage grid was a concern. The two longest trusses which span across the grid are provided with pre-stretched steel wire rope 'bow strings' which pass underneath the trusses and over two intermediate frames which cantilever down below the truss. The tension in the wire rope is monitored by load cells and is such that sufficient uplift is provided to reduce the overall deflection of the truss.

total fabrications
It wasn't long after Ian Locke began as Technical Coordinator at Fairfield Halls in Croydon, England, that he set about ensuring the much used stage was efficient and safe. Consequently there has been, in his own words "huge changes", not least the installation last August of a new rigging grid above the famous Fairfield stage. To source the new rig Locke visited PLASA 2002: "When I stopped by the Total Fabrications stand I was more than impressed with the T2 system."

Locke has invested heavily in the T2 system, 44 metres of trussing in a variety of lengths for maximum grid configurability. He also purchased a quantity of accessories that are integral to the T2 safety ethos; "We've got pick-up and hanging points - especially useful for visiting pop groups who often want to rig a mid truss - or any production that wants to hang old style trusses beneath the grid. I also have T2 half clamp couplers for fixing six lamp bars; and T Clamps for luminaires. These are a particularly versatile clamp, we currently use them to attach our existing tab-track and masking drapes to the grid." Total Fabrications's Chris Higgs has trained four Users, two Supervisors, who have completed Rescue training, and Locke and his deputy attended Operator/Installer training prior to installation.

pcm & slingco
PCM and Slingco - two leading entertainment industry manufacturers - have collaborated to design and launch an exiting new product - the Unibar. The Unibar system allows for the quick and easy raising/lowering of suspension or lighting bars for scenery and lighting equipment with a motor-driven unit. Unibar is a flexible user friendly unit, designed to be installed onto any style of fixing or structure, including universal beams, trussing, channels and barrels. The system is a cost-effective alternative to the more sophisticated power-assisted winch sets. Tony Griffiths comments "Unibar fills a gap between these type of products and manual winches or hemp sets. It's ideal for schools, colleges, sports halls, smaller theatres, amateur dramatic and touring applications".

Initially available in 250 or 500 Kg models with single or two speed options. the entire Unibar unit is self-contained, with the motor unit positioned on the end of the track. Single or three phase power options are offered, and other product highlights include simple, logical 'Plug-and-Play' operation. Dual brakes are also available as an option.

The product has been designed to support any number of suspension cables and any length of suspension bar with ultimate top and bottom limits contained within the unit's controls. Unibar allows the units to be positioned side by side with the suspension bars positioned at 200 mm centres - a real must in theatres. The Unibar control panel can either be fixed to the wall or operated by hand held remote.

camco
CAMCO truss systems are high-quality components for professional event engineering. Their engineers have created truss systems for almost all applications, which meet the latest technical and relevant safety requirements. One example of this is the XL-type trusses. The main load-bearing tubes of the XL-type trusses are special aluminium tubes with an outer diameter of 60.0 mm. They have proved a prerequisite for an easy combination with standard scaffolds. The XL-type trusses have been designed to accommodate extra heavy loads in exhibition or event halls, for outdoor constructions such as mobile stage roofs, or for touring. Their greatest advantages are their resistance to buckling and an outstanding load-bearing capacity. Diagonal bracing on each side make XL-type trusses particularly suitable for structures that need to carry combined loads or are used for the largest spans.

atc
One of the most important demands of SR1.0 (the new german truss regulation issued by VPLT) is that any new truss sold has to be marked permanently and clearly by the producer; the information given has to include producer, date of production, type of truss and identity number In answer to this, ATC Austria developed a specific solution and applied for a European patent (EP 1 327 729, 16.07.2003). The Austrian patent has been granted already in 2002 (15.12. AP 410.816).

The main advantage is the permanent connection between truss and mark as it is welded to the truss. All the information itself is engraved. The part carrying data is welded to both ends of our trusses (and corners of course). One end is used by ATC for the above mentioned information, the other can be (and is) used by ATC customers to engrave - for example - their logo which can be programmed and engraved by ATC on request.

litestructures
The Clubhouse is one of the newest and most talked about nightclubs in Leicester, UK. Originally a traditional gentleman's club, a complete refurbishment has built on the classic decor already present. Owner Mac Taylor specified the entire fit out for the club, with the aim of fusing traditional with modern and as such the old oak doors and wall panels remain, but Mac brought Litestructures on board to bring The Clubhouse into line with the 21st century.

Providing the trussing and lighting, Litestructures was given the brief to come up with something simple yet stylish. Using Astralite AO3 trussing throughout, the design incorporates a selection of square units flown in the restaurant and bar areas, as well as the entrance, hallways and landings. Circular units are fitted in the upstairs dance area, while over the bar areas, the trussing follows a diagonal line which had to be custom-built. Litestructures' Martin Featherstone said: "Because Litestructures trussing is designed and manufactured by the company itself, making one-off pieces to suit individual needs is not a problem and the client can be confident that it will all fit together. And because it comes in modular sections it can all be built on site."

The trussing was designed specifically for lighting, which was also installed by Litestructures. Parcans Par 56 chrome cams and pinspots were used throughout, while intelligent lighting was used in the upstairs dance area. UV Cannons were used to highlight the large pictures and hanging drapes on the walls.

One of several truss designs offered by Litestructures, Astralite is well established as an industry standard, offering an excellent strength-to-weight ratio at a very competitive price. It is available in a variety of designs, from circular layouts to special dimensions and complete custom structures. Litestructures is also able to offer productions to customers' drawings coupled with a complete design service.
