Sound Intensity Level

Consistent speeds with or without load and the quietest operating sound levels available (down to 60 db), mean no distractions during performances.

Hoists generate some audible noise during operation. The total noise level experienced in the operating area is a combination of the individual noise sources around the operator. The main sources of noise from the hoist arise from its components, vibrating structures and reflective surfaces.

Hoist components which generate noise:

  • Hoisting Machinery
  • Moving structures associated with the hoist.

Typically, when the operating location is more than 5m (16ft) from the hoist and associated moving components, the average combined noise pressure level due to the hoist and its associated components will not exceed 65 dB(A) at the operating location. The noise pressure level rises as the operator moves closer to the sources of noise.

The noise pressure level can exceed 65 dB(A) if, for example:

  • The operator operates the hoist from somewhere close to the moving components.
  • The truss or building structures resonate heavily
  • The walls or other surfaces at the working site reflect noise towards the operator
  • The optional warning devices are functioning

If the noise levels seem high, measurements should be taken while the equipment is working under normal operating conditions. Follow local recommendations and use personal hearing protection if recommended.
