The panels are designed so that four of the six panels slide horizontally, stored behind the fixed panel on each side.
The doors would be opening and closing frequently to create a view of the Las Vegas Strip while enjoying a game of American football or an event.
Enclos worked with Demag sales engineers to determine the best possible solution to move the heavy doors and decided upon Demag DRS500 wheel blocks and W-gearboxes matched with a Demag ZBA brake motor.
Brian Stephens, product manager, Demag Handling Technologies, added: “The design of the Demag wheel system, which includes the ZBA brake motor, has always been ideal for applications like the lanai doors at the stadium because it provides safe and reliable braking.”
Each panel uses two Demag DRS500 Wheel Blocks with W gears that run on 79kg per yard hardened steel rails, travelling approximately 100 metres.
To drive the doors, the Demag ZBA brake motor with 1.8-kw, 460 volt is direct-coupled to the DRS wheel block through a Demag 258:1 reduction high efficiency gear reducer.
Demag DRS500 wheel blocks are used for the heaviest loads. With standard, off-the-shelf wheel shapes or customized designs.
“Knowing the Demag solution was designed for easy maintenance was key to this project. If a solution was presented that was going to take herculean effort to maintain, it wasn’t going to fit the job,” said John Lanari, PE, Enclos.
