Especially developed for stage technology applications

The "Delta classic" and "Delta redundant" electric wire role winch are available in five basic design sizes to take loads from 2.5 kN to 25 kN. These winches offer the outstanding performance, absolute safety and low noise levels essential in the world of theatre and event organisation.

Up to eight cable outlets can be provided from the cable drum in both Delta Winches, depending on customer requirements. This means that even the most complicated lifting and lowering processes from backdrops or other stage structures are possible. Effective operation is provided by the electric controls, with an infinitely variable speed regulation from 0.0 to 1.8 m/s. A full load can even be held for 60 minutes without using the brake.

Safety is one of the major factors of the "Delta classic" and "Delta redundant". Both Wire Rope Winches comply with BGV-C1 and DIN 56950 standards and meet all safety requirements for technical equipment in the stage sector. With its doubled superstructure, two drive motors with redundant safety brakes and two transmissions, the "Delta redundant" is also equipped for "emergencies", so if a motor fails unexpectedly, the second motor automatically takes over its work; this “emergency” electrical drive is included as standard within the price, and it not only protects the people in the surrounding area of the stage, but also ensures that the show or performance can continue without any difficulty.

Another outstanding feature of the Delta Wire Rope Winch is its quite running. At a distance of 1 m, it produces 60 db(A) maximum. This characteristic, which is of vital importance for stage technology, is due to the sophisticated "driving-axle-system". Here, the Wire Rope Winch describes, on an indexing slide, a sideways movement, whilst the cable is wrapped around the drum at the same time. The result is a cable run-in angle of 0°, which reduces not only noise emissions but also keeps wear and tear to a minimum.

Owing to its high standard of safety, this Electric Wire Rope Winch can be used anywhere where people need to move or perform beneath loads, e.g. for lifting display elements in department stores or theatres.

The winches also have an extremely long working life because of their design according to the 2m engine group. This means that the expected working life of the low-maintenance "Delta classic" and "Delta redundant" is 1,600 hours at double load.

In addition to its Delta Winches, Pfaff-silberblau offers an extensive range of high-quality Electric Wire Rope Winches in the BETA model series, with load bearing capacities of 2.5 kN to 75 kN.
