Bottom mechanics

What is the under-stage mechanism and why does it require specialized care?

Under-stage mechanism includes all technical equipment built into the stage floor, understage and adjacent technical spaces. These devices operate with high weights and often use complex hydraulic, mechanical or electromechanical drives. The main elements that we routinely overhaul and service include:

• Stage tables and drop-down tables (hydraulic, spindle, chain or scissor lift platforms),
• Orchestra platforms and orchestra tables used to smoothly change the height level of the orchestra,
• Stage turntables (built-in and mobile stage turntables including drive units and directional guides),
• Leveling and covering bridges, drop-down flaps and sliding floor panels,
• Stage trolleys and sliding joinery for quick reconstruction of stage elements,
• Hydraulic aggregates, distribution and control systems of the lower mechanics.

The lower mechanics equipment is exposed to extreme mechanical stress and static load. Hydraulic failure, wear of guideways or a defect in the brake system can lead to the platform getting stuck during a performance or to a serious injury. Regular revision of stage technology is therefore a key step in eliminating risks and maintaining the smooth operation of your cultural stand.

Our services: Complete revision and service of lower mechanics

At TECHARTSTAV we offer a comprehensive portfolio of services tailored to the specifics of your understage areas. Whether you have historical spindle drives or cutting-edge hydraulic technology, we will ensure their flawless operation.

1. Regular revisions and professional inspections of lifting equipment

We carry out certified periodic revisions of lower mechanics in accordance with applicable legislative requirements and normative regulations for lifting equipment. The output of our work is an official audit report acceptable to state professional supervision bodies and insurance companies.

As part of the audit inspection, we perform:

• Inspection of steel supporting structures, welds, guide rails and anchor points,
• A thorough inspection of drive systems (hydraulic cylinders, mechanical screws, toothed racks, support ropes and chains),
• Testing of hydraulic circuits for leaks, pressure testing and checking the condition of oil fillings,
• Inspection of safety elements – limit switches, latch systems, catchers and obstacle detection,
• Inspection of electrical wiring, switchboards, control panels and CENTRAL STOP safety circuits.

2. Preventive service and maintenance of understage equipment

Proper maintenance extends the life of expensive equipment by years. Our preventive service of understage mechanics includes regular lubrication of movement screws, replacement of hydraulic filters and operating fluids, adjustment of guide rollers, tightening of structural joints and calibration of position sensors.

3. Quick repairs and troubleshooting

We react promptly when a malfunction occurs. We perform repairs of stage tables, sealing of hydraulic piston rods, replacement of damaged bearings, repairs of gearboxes and modifications of control electronics. We have our own technical facilities, thanks to which we can solve most of the problems in the shortest possible time.

4. Modernization and reconstruction of the lower mechanics

Does your understage technology not meet current demands for noise, speed or safety? We will design and implement modernization of the lower mechanics. We will replace outdated manual or noisy drives with modern silent hydraulic systems or electric motors with continuous speed regulation.

Why entrust the lower mechanics to TECHARTSTAV?

• Expert knowledge of the field: Our technicians have deep experience with the specific requirements of stage technology, where the emphasis is on absolutely silent and smooth operation.
• Mechanical and constructional background: As a stable company, we can assess not only the mechanics themselves, but also the static impacts on the building structure and the construction readiness of the understage area.
• Maximum emphasis on safety: We strictly ensure compliance with ČSN and EN standards relating to the classification for the stage and lifting platforms for the transport of people and materials.
• Flexible work planning: We will fully adapt the schedule of service and inspection work to your theater schedule, rehearsals and theater holidays.
• Complete documentation: We guarantee clear processing of all inspection protocols, which will provide you with legal certainty during any inspection.

How is a service intervention or inspection carried out?

1. Initial consultation: We will evaluate your needs and the current condition of the lower mechanics on your stage.
2. Physical inspection on stage: Our specialist will conduct a detailed inspection of the understage areas, hydraulic stations and structural elements.
3. Professional execution of work: We will carry out inspection tests, load tests or agreed service tasks.
4. Handover of inspection news: We will provide you with complete documentation including recommendations for the further safe operation of the equipment.

Don’t leave the safety of the scene to chance. Entrust the revision and service of the lower mechanics to professionals from the TECHARTSTAV team.
