Air Technical Industries of Mentor, Ohio is announcing the development of an extra-large, circular stage lift. The moon-shaped circular deck adds a new dimension of excitement to a show or concert.
The unit shown is more than 7 feet wide and 42 feet long. It raises an entire orchestra cast with piano and all the instruments up to 144 inches in the air. The specially fitted curved platform perfectly matches the shape of the pit in which it is installed.
Capacity of the lift is 10,000 pounds with over 3:1 safety factor. The hydraulically operated lifting action is provided by six hydraulic cylinders featuring chrome plated shafts to provide smooth, quiet operation and to prevent corrosion. The cylinders are synchronized for uniform, level lifting by a precision-built flow divider. Each cylinder is equipped with a pilot operated safety holding valve to prevent the stage lift from accidental lowering in case of power or hydraulic failure. The hydraulic system is also equipped with a safety pressure relief valve to prevent overloading.
The electric powerpack is remotely installed in a separate enclosure to keep the operation quiet and clean. The 10HP electric motor is 480V, 3-phase, 60 Hz and the dual push button controls are 110V operated, one mounted on the lift and one located at the lower level.
The lift is all welded steel construction, built heavy duty for dependable, safe, and long-lasting, maintenance free operation. The tandem stage lift can be disassembled in three major sections that bolt together. The durable connecting rods keep the three sections mechanically synchronized for uniform, level lifting even when the load is not uniformly distributed (for example, the piano at one end is heavier than the violinist at the other!)
The lift has many other potential industrial applications with a great many benefits including increased performance, improved safety, reduced injuries and fatigue, time savings and increased visibility. For instance, large aircraft manufacturers are manually erecting scaffolding to assemble the fuselage of an aircraft. This is an expensive process with lots of wasted time and space that delays the manufacturing process.
The stage lift can be built into the ground and then elevate the workers with all the tools when and where needed immediately and safely with enormous time savings and improved performance.
Some other applications include large assembly works, cargo loading and handling, paint application of large items, second floor access with cargo, mezzanine work, or product displays elevated for greater visibility. There are many sizes, lifting heights, and capacities available to meet any specific and specialized needs.
