No-Fly Zoning with Two Independent Trolleys on a Crane

By December 27, 2023No Comments

When two trolleys are independently operated by an overhead crane, they may be restricted in certain areas. The Crane Sentry® Zone Manager II series allows end-users to easily navigate these no-fly zones.

Depending on the location and shape of the restricted area, you can choose from two options:

  1. If the restricted area is against one side of the crane span, you can use our standard two-laser Crane Sentry® Zone Manager II and aim the trolley laser at the trolley closest to the restriction. This ensures that both trolleys cannot enter the restricted area.
  2. If the restricted area is in the middle of the span and the end user wishes to operate the crane around all sides of the area, our Crane Sentry® Dual Trolley Zone Manager II will permit this. It allows for independent control of each trolley to avoid potential breach of the restricted area by either trolley.

Crane Sentry® Zone Manager II is simple to install, configure, and operate. It can help you create safer working conditions, protect your equipment and personnel, and optimize your crane operation.
