Actuators

With an extensive range of theatrical lifts to meet all your challenging vertical needs, a Serapid system is the perfect choice for orchestra lifts, stage lifts and theatre production machinery integration. For over 30 years, Serapid has provided customised linear motion solutions across a vast range of industries. At the heart of each solution lies Serapid's unique rigid chain technology. The links of the Serapid rigid chain lock together to form steel rods capable of providing long horizontal stroke actuation, as well as, powerful and precise lifting solutions. Unlike traditional actuators, the chains can be coiled up and stored in a variety of compact storage configurations, which results in space savings and design flexibility.

LinkLift

Serapid manufactures the LinkLift™Rigid Chain products specifically designed for lifting.

Some of LinkLift�s advantages include:
- Silence: 45 dBA at 50 mm/s (1.9 in./s). Combined with a low-noise motor drive, this feature allows the chain to be operated during a performance.
- Precision:The link plates are precision-formed to within a 100th of a mm thanks to a highly accurate manufacturing technique developed for the automotive industry. Such precision guarantees positioning to within a millimetre.
- Speed: Speeds of up to 200 mm/s (7.9 in./s). Serapid recommends this as a normal operating speed, but higher speeds are possible.
- Low maintenance: Nothing more than annual lubrication is necessary, in a well maintained theatre environment.
- Reliability: Foolproof pinion/chain gearing. The system incorporates a minimum number of slow moving parts.
- Security: The chain is capable of applying thrust in addition to dynamic traction guaranteeing movement irrespective of the flexibility and position of the load on the platform. In the case of an accidental impact, the quality of the materials used and their design protects against any distortion of component parts. Under normal use conditions the chain cannot be unlocked.
