About the Client:
Straight Eight Engineering provides premium marquee washing machines for purchase, servicing, and short and long-term rental. Designed and manufactured in Hampshire, UK, the machines can wash marquee sections up to 50 m in length and 5 to 6 m wide (depending on the machine), and offer an efficient and cost-effective way for companies and individuals to clean their marquees.
As part of the Straight Eight Engineering cleaning process, marquee panels go through four stages of the washing cycle:
- Loading and prewashing treatment
- Rinsing and drying
- Flaking and packing away
When the washing process starts, the top carriage, which holds the marquee cover in place, has been designed to move to the center of the machine so that the panels can be unrolled and cleaned.
Because of the design, Straight Eight Engineering required a system that would allow the top carriage (shown in the photo below) to move from one section of the machine to the other, without it stopping and delaying the process.The solution provided also had to accommodate the weight and pressure of the carriage when it’s in motion.
This is where Harken Industrial was able to assist, by providing suitable equipment to improve the efficiency and functionality of Straight Eight Engineering’s machines.
The Harken Industrial Solution:
With our knowledge and experience in load-handling, Harken Industrial offered a solution to Straight Eight Engineering by suggesting two key products; the R32 rail, along with one of our utility trolleys (part number IN148).
Each washing machine required a total of two rails and two trolleys to be installed, one at each end of the unit. The trolleys ran on the new installed rails, and the top carriage was attached to the trolleys on each side of the machine.
With a maximum rated load of 200 kg (20 kN / 440 lb), applying a safety factor of 4:1 for equipment, and low-friction ball bearings, the trolleys offer flexibility by taking the weight of the carriage and moving freely on the rails without disruption.This setup is exactly what Straight Eight Engineering was looking for as it makes movement, maintenance and cleaning much easier. The Harken Industrial rail and trolley system has also been designed to withstand harsh environmental conditions, which is an added benefit during the washing cycle.
Overall, the existing setup was upgraded, and a new, reliable and long-lasting system was deployed to improve the washing process and performance of Straight Eight Engineering’s machines.
The photo below shows the rail system attached on top of the metal arm of Straight Eight Engineering’s washing machine.
Summary and Legacy:
This project highlights the diversity in how Harken Industrial’s equipment can be used in a wide range of industries, sectors and applications.
Besides being used on boats and in the architectural world, load-handling apparatus is also ideal for moving industrial machinery in the utilities sector, as well as other areas, including window-washing apparatus, human suspension systems, and hoisting and moving stage equipment.
This case study details how trolley and rail systems can be used as a simple and low-maintenance way to transfer loads smoothly.
For anyone who requires a similar setup on a project they are working on, it’s also worth considering that rails can be bent to suit various applications.
“The equipment that Harken Industrial suggested to us has helped improve the functionality of our washing machines. The trolley and rail system can take the weight of our carriages and allows the marquee panels to move smoothly through the washing process. It’s an accurate system, it provides the correct alignment we needed as part of our setup, and it doesn’t rust over time.”
“Furthermore, one of the main benefits of the Harken Industrial utility trolleys is that the ball bearings don’t come out under pressure. For us, this is invaluable and has ultimately enabled our washing machines to operate more efficiently. Overall we have been extremely happy with the equipment and service offered by Harken Industrial.”
