Self-Climbing Lighting Hoists

ACTA20 Studio Lift

Self-Climbing lighting hoist with up to 3 m (10') pipe and up to 6 lighting circuits

Onboard motor self-climbing hoist to raise and lower lighting fixtures. Provides easy and fast access to install and service studio lighting fixtures. 

The versatility and ease of installation and use make the IFF self-climbing hoists the ideal solution for high lighting grids and frequent set changes in television studios that require a quick and easy change of lighting sets.

The advantage of the ACTA 20 for the end user - studio designer, rigger or technician - is that this single motor winch answers most lifting and suspension needs, thus avoiding the use of a vast number of different single spec hoists in a studio, theater or auditorium. This, in turn, means that all stages of delivery, set-up, and use can be dramatically streamlined – new studios can be completed faster, existing studios can be kept in perfect running order without maintenance delays.
