Upper mechanics

What is upper stage mechanics and why is its revision essential?

Upper stage mechanics includes all the equipment located above the stage, in the grid (ropeway) and in the technical bridges. It is used to manipulate backdrops, decorative elements, light bridges, sound systems, curtains and other stage equipment. The main elements that we routinely inspect and service include:

• Stage pulls (manual rope pulls, counterweight pulls, electric motor pulls and hydraulic pull systems),
• Point pulls and winches for flexible suspension of loads at any point on the stage,
• Laying systems, cable lines, support ropes, chains and hoists,
• Light bridges, batteries and mobile supporting structures,
• Main and inter-act curtains, including drives and control systems,
• Fire curtains (safety partitions), which represent a key element of the building’s fire protection.

Since the upper mechanics work with heavy loads suspended directly above people’s heads, any wear, material fatigue or technical defect can have fatal consequences. Regular revisions of stage equipment are therefore not only a legal obligation, but above all a necessary investment in the safety of actors, technicians and spectators.

What services do we provide within the framework of the revision and service of upper mechanics?

At TECHARTSTAV, we approach each project individually. Whether you manage a historical theatre with traditional manual pulls, or a modern cultural centre with fully automated computerised control, our team of technicians will ensure care at the highest level.

1. Regular statutory revisions and professional inspections

We carry out periodic revisions of upper mechanics in accordance with the standards for lifting equipment and stage technology. The result of our inspection is always a detailed inspection report, which serves as an official document for state supervisory authorities, insurance companies and the final inspection procedure.

The inspection includes:

• Visual inspection of supporting steel structures, gratings and anchoring elements,
• Thorough inspection of supporting cables, chains, clamps, cable drums and pulley tracks,
• Functional testing of brake systems, limit switches and overload fuses,
• Inspection of electric drives, gearboxes, switchboards and control panels,
• Tests of operational reliability and emergency stop (STOP systems).

2. Preventive maintenance and diagnostics

We don’t wait for something to break. Preventive maintenance of upper mechanics will reveal minor defects and wear before they cause a performance shutdown or an expensive accident. As part of maintenance, we adjust ropeways, lubricate mechanical parts, adjust brakes, tighten joints and clean key components.

3. Repairs and service interventions

If a malfunction occurs, we react quickly. We perform repairs of stage pulls, replacements of worn ropes, repairs of gearboxes, replacement of electric motors and repairs of electronic controls. We hold the necessary spare parts and, thanks to our own capacity, we can return your stage to full operation in a short time.

4. Modernization and reconstruction of upper mechanics

Does your existing stage mechanization no longer meet today’s demands for speed, load capacity or safety? We offer complete modernization of upper mechanics – from replacing manual pulls with electric ones to installing modern continuous drive control systems (frequency converters, safety PLCs).

Why choose TECHARTSTAV for the service of your stage technology?

• We are professionals in the field: We combine deep knowledge of theater technology with a solid background in a construction and engineering company. We understand not only the equipment itself, but also the statics of buildings and related professions.
• A comprehensive solution under one roof: We can handle everything from the initial condition assessment, through the project, inspection, regular stage technology service to general reconstructions.
• Emphasis on legislation and safety: Our procedures strictly respect the valid Czech and European standards (ČSN, EN) regarding machinery and hoists in the theater environment.
• Speed ​​and flexibility: We know how demanding the operation is in theaters and cultural centers. We always adapt the dates of inspections and service work to your playing schedule and rehearsals so as not to disrupt the operation of the stage.
• Transparent certification: After the work is completed, you will receive clearly structured documentation and a lifting equipment inspection report, which will provide you with 100% certainty during inspections.

How does cooperation with us work?

1. Inquiry and consultation: Contact us with your request. We will discuss the scope of the equipment and the current state of your technology.
2. On-site inspection: Our technician will visit your facility, conduct a tour of the ropeway and grating and propose the optimal scope of work.
3. Implementation of inspection or service: At the agreed date, we will perform a complete service and inspection of the upper mechanics.
4. Handover of documentation: You will receive a valid inspection report, a list of the tasks performed and any recommendations for further safe operation.

Ensure the smooth and safe operation of your performances. Entrust the revision and service of the upper mechanics to the experts from TECHARTSTAV.
