Overstage machinery

 

• fly bar hoists, controlled & non-controlled
• manual counterweight hoists
• chain hoists
• point hoists
• lighting hoists
• portal bridges, static & movable
• portal towers, static & movable
• curtain hoisting systems
• galleries, grid floor structures and steel structures

 

The overstage machinery incorporates that part of the technical stage equipment which extends from stage floor level up all the way to under the roof. This area is separated into the proscenium area, the grid floor and second grid floor, and the gallery area.
The proscenium area encompasses the (mostly) movable portal bridge with the laterally mov­able, annexed portal towers. The grid floor and second grid floor constitute the uppermost levels of the technical stage equipment, and, in addition to the guiding pulleys of the hoisting equipment installed on that level, usually also houses the majority of the electro-mechanical hoists.

A general distinction is made between the following hoist types and variants: fly bar hoists, panorama hoists, lighting hoists, point hoists, and chain hoists. From the grid level down each level of the stage tower contains an all-around lighting gal­lery. Lately, the lowest gallery is usually equipped with additional pole suspensions for lighting bodies with low payloads.

Technical details

Due to W&P Anlagenbau’s all encompassing company structure, all hoists are made in-house, all the way from the planning phase to the first test run.

Hoist design is optimized in terms of compactness, reliability and noise emission, while all sensors required according to BGV C1 are arranged for good view and access, and may even be evaluated right on site if needed, and the data transmitted to the higher-order computer control via ProfiBUS, ProfiNET or Ethernet.

Hoist design increasingly includes a winding device integrated right into the hoist to meet the space situation of existing installation and/or to achiever higher installation density, i.e. narrower spaces between the hoists. Machine hoists are generally available as fly bar hoists and point hoists with payloads between 350daN and 750daN and velocities up to 1.8m/s.

Models like the so-called “smart winch“ with its limitless application possibilities are also available as part of W&P’s standard range.
