Absolute encoders are central to success of theatrical effects

Heidenhain absolute encoder technology is playing a key role in the global success of Stage Technologies' stage engineering automation systems that enthral audiences at entertainment venues throughout the world by moving sets, scenery, people and objects accurately and safely.

Based in London and with offices in Las Vegas, Macau, Australia and Italy, award-winning Stage Technologies has, since its inception in 1994, been an automation supplier of choice for many venues and it has consistently achieved defining moments in live entertainment history in more than 30 countries worldwide. Central to this continued success are .

For example, Heidenhain ECN 1113 single-turn encoders are regularly integrated into specially-designed wheel motors, while Heidenhain ROQ 425 and EQN 425 multi-turn encoders are used on winches. In one particularly innovative application, the two encoder types are combined in moving trolleys that incorporate rotating winches to enable objects or people to be 'flown' around and across stages.

The ECN, ROQ and EQN encoders are a small part of a comprehensive array of angular, linear and rotary encoders, digital readouts and CNC systems available from Heidenhain (GB).

Ease of integration

Stage Technologies' Director of Mechanical Engineering, Ewart Richardson, comments: "Heidenhain encoders are selected by us not only due to their ease of integration (EnDat compatibility) with the motors we use, but also because they consistently provide enhanced reliability and accurate repeatability - which is obviously crucial to everything we do."

Whether a turnkey system or a single-axis control, an ultra-high-speed winch or a radio-controlled stage truck, Stage Technologies provides systems that follow guidelines such as EN 61508 and conform to quality management systems such as ISO 9001:2000, as well as incorporating any appropriate safety features (for example, emergency stop switches, 'dead man's handles,' light curtains or 'safe edges').

The company's systems have been successfully employed worldwide in theatres, opera houses, West End musicals, cruise ships and rock concerts, as well as for films and TV. In 2009 Stage Technologies received The Queen's Awards for Enterprise: International Trade for the second time, the first occasion being in 2003.
