Hoist UK were approached by Cohesion Engineering, a stage engineering company in Hong Kong who were the contracted rigging company for the new area of Ocean Park, a popular marine animal park, theme park and oceanarium situated in the southern district of Hong Kong. The customer required lighting trusses for the theme park which would be suspended above the public in their new water park attraction.
Hoist UK’s experienced sales team and skilled team of design engineers worked with the customer remotely to deliver a turnkey solution based on their requirements, specifications and preliminary CAD design drawings. The final design was submitted to the client along with approval drawings and wiring diagrams to ensure the customer was satisfied and that all requirements from the specification were met.
The safety features on this bespoke design were vital as the lighting trusses were to be suspended above the public in the water park of Ocean Park’s Invigorating Island South attraction. The position of the lighting trusses within the attraction had to be considered in the design, and how the humidity of the environment may affect the hoist.
Hoist UK supplied the customer with the Stagemaker SL manufactured by Verlinde. Each hoist was rated to 1000kg and met the safety standard of BS 7906 CAT A, which allows a static suspension of loads above people without the requirement of a secondary safety device. This hoist was found to be the best solution to meet the requirements of the specification, boasting double brakes, low voltage control, and a four-position geared limit switch; adding further safety for the operator when raising and lowering the load. In addition to this, Hoist UK retrofitted the hoists with incremental encoders which would allow the customer to pre-programme set trim heights for the lighting trusses for use in the various configurations.
Furthermore, the Stagemaker SL is designed and manufactured as standard with an IP rating of 55 (IP55), which made this even more attractive to the customer, offering protection over potential water ingress in the humid environment of the water park.
A twelve-channel control system was also embedded in the design, allowing for the twelve individual hoists to be moved as either a selected group, or individually if required at a fixed speed, which for the SL10 chain hoists was 4m/min. The control system featured a HMI Touch screen handset which displays a visual illustration of the current position of the hoists. The hoist control system was designed to memorise up to 10 pre-programmable positions via a ‘Teach me’ function so that positions can be recalled at any time.
Detailed wiring schematics and owner manuals were supplied to assist with the ease of installation on site.
“This project is another great example of how our skilled team here at Hoist UK have the vision, technical knowledge and experience to take standard ‘off the shelf’ products, and develop them with the addition of our own manufactured products to offer a bespoke solution that fulfils the clients requirements”
