SHOOK DELIVERS FIRST PLC
CONTROLLED GIANT MOBILE VIDEO DISPLAY
SCHERTZ,
TEXAS -- Shook Mobile Technology announced today completion and
delivery of what is believed to be the first PLC controlled
entrant into the growing mobile outdoor LED video screen market.
A Programmable Logic Controller (PLC) automates deployment and
positioning of the massive display to the point that it can be
operated by a single person.
Shook
designed and built this 53’ long trailer for the Diamond Vision
Systems Division of Mitsubishi Electric Power Products Inc., who
in turn provided it to their customer, Texas A&M Athletics. The
system will début Saturday, November 4th in
connection with A&M’s highly charged football game against the
University of Oklahoma at Kyle Field in College Station, Texas.
Capable of
operation in winds of up to 40mph, the screen can be raised 30’
above the ground and rotated in any direction by Shook’s unique
telescoping mast system. The exceptionally vivid Mitsubishi
Diamond Visionâ
LED screen is 26’ wide and 14’ tall. A complete TV Broadcast
Production Studio is also on board, enclosed in a 19’ housing on
the front of the trailer. A 70kw generator and full length
retractable canvas cover complete the package.
“This was
a very exciting project that put all our capabilities to the
test” says Shook CEO John Heaney. In order to fit neatly on the
trailer and be legal for over-the-road transport, the giant
screen has to split in half. Precise realignment of the two
screens each time it is deployed is essential for proper
operation. “Ease of use and safety were the two main factors
driving us to incorporate PLC controls” says Heaney. .
The operator has complete control over the mast and screen
system via a handheld touch-screen control panel. The system
incorporates highly accurate encoders and sensors to constantly
monitor the mast and screen’s position and movement. The
PLC also monitors numerous safety inputs and will not allow
operation if an unsafe condition exists.
