TV Rigging & Suspension
PMM Hoist
Motorised system with ISS
|
| PMM Hoist Motorised system with ISS |
ADB offers over 35 years experience in the design and manufacture of lighting equipment for national and private TV studios: custom solutions come from standard components. All suspension and rigging needs can be satisfied by using combinations of motorised hoists, telescopes and pantographs. ADB's Intelligent Safety System (ISS) offers maximum safety during use.
Motorised hoists efficiently solve all problems of luminaire suspension regardless of studio height. Several luminaires can be easily rigged and vertically moved, whilst the light intensity is individually controlled.
Hoists & Telescopes with ISS
ADB's motorised hoist and telescope systems are designed primarily for application in TV studios whenever safety and operating costs are the prime consideration. ADB self-climbing motorised units are supplied with real-time load variation monitoring system for maximum safety. High and low limit switches, together with overtravel limit switches offer further protection. Common options include:
Infrared remote control; Memorisation of position; Soft start.
Pantographs
ADB pantographs are available in a range of specifications, offering friction, pole-operated or motorised systems. Various loading limits and drops can be specified: the table below shows the products available.

ISS: Intelligent Safety System
Motorised hoist and telescope systems are equipped with ISS, ADB's proprietary Intelligent Safety System, which represents a totally new approach to suspension safety and reliability in a TV studio. Conventional no-load and overload sensing systems tend to stop the hoist when it is too late, and in addition require substantial maintenance work.
ISS first measures the initial load (which becomes the reference load) before any travel up or down, then monitors in real-time any variation of this reference load, and eventually stops the hoist if the variation exceeds a certain value as determined by the sensitivity level manually selected by the operator.
A hoist stopped on its way up or down can only be re-started in the opposite direction. A hoist set to low sensitivity, during rigging work for example, will automatically go back to high sensitivity after ten minutes of no solicitation. The load variation sensing works on all suspension ropes, irrespective of the load distribution of the barrel.
ISS also counts the number of travels of the hoist/telescope and provides a maintenance warning signal in due time. ISS physically consists of load sensing devices mounted onto the rope anchoring plates, together with an electronic control unit for mounting under the top fixing beam. Features include:
Instant stop on obstacles; Instant stop in case of accidental load variation; Adjustable load variation sensitivity level; Maintenance warning signal.
