Why? Danger
Most schools use the hall for the purpose of assembly, performances and physical education lessons. It is often the main activity space for the whole school. Because of its usage and importance, the safe practice of installing equipment in the hall should always be considered.
The problem of ageing lifting appliances and lifting gear (LA/LG) is a concern. Some installations like the fly system and light bar lifting system often have a rusty or damaged wire rope. The condition of such installations must be inspected as they have the potential to fall down.

rope break due to excessive strain

rope failing from fatigue after bending over small sheaves

In addition to that, most of the stage equipment in a school hall is not suitable for all the diverse learning activities required in different areas due to the school’s out-dated design, especially those built many years ago.
Drama classes and school performances make up a large part of school activities. Drapery and scenery/the light bar is frequently lifted so its operational smoothness and good condition is extremely important.

How? Replace and maintenance
Cohesion Engineering has a total solution for schools, especially the school was built after 2000year(Millennium School)
- To replace wire ropes
- To replace pulley components
- To replace winches
- To reconstruct the light bar with new layout
- To issue a safety certificate with recognized S.W.L for all lifting gear from a registered engineer (R.P.E)
- Preventive maintenance
- A site survey is free to provide upon inquiry. Our team will highlight the condition of the existing lifting gears and the fly systems by check up At-A-Glance. After that, we will explain the risk to the school and will discuss the possibility of upgrading.
- The team will adapt a load cell into the counterweight system to measure the fly load before construction to ensure the new system come with enough S.W.L.
- In stage of closing of the project, a full set of documents including Form 4 & Form 5 certificates will be submitted to the school for user acceptance.
- Preventive maintenance will be conducted every 6 months in the first 2 years(a total of 3 times) after the Form 4 has been issued. After that, the renewal is optional.

More? Be more like a theatre
As indicated above, playing drama and kinds of performance are must to have activities in many schools. Due to old design, drapery includes main curtain may not moving smoothly, especially the winch and the track. They make noise when operate thus always being abandoned for artistic concern.
