Interview on the site report ‘Solutions in the tightest of spaces’

1.    What specific challenges were overcome by installing the GEDA hoists?

Erecting the scaffolding in this boiler presented us with particular logistical challenges. The boiler’s manhole was situated 10.5 metres above the ground. The platform in front of it had an area of only approximately 4.5 m². The manhole measured 0.9 m × 0.9 m. The weight of the materials to be installed was approximately 160 tonnes, and we had only six working days available for the planned erection.
Analysing these key figures presented us with two major challenges: time and staffing. As regards the time factor, the client’s requirements were non-negotiable. As regards staffing, the focus was on the availability, quality and continuity of staff throughout the entire set-up and dismantling phases.
During a meeting with Mr Wasilczyk, I was introduced to the capabilities of the GEDA 300 Z Boiler hoist. That was the starting point for the subsequent decision-making process.

2.    Why were the GEDA 1500 Z/ZP, the GEDA 300 Z boiler hoists and the GEDA MAXI 150 S the ideal combination for this project?

The maximum load capacity of the GEDA 300 Z Boiler Hoist, at 300 kilograms, was the key specification. This determined the size of the material packages. These were set at 280 kilograms to prevent overloading and potential malfunctions of the hoist. This package size was also ideal for the staff installing the material.
However, the 280-kilogramme package size presented us with another problem: how do we get the package through the manhole and into the cage of the GEDA 300 Z Boiler Hoist? As we had already decided at this stage to pick the packages in the warehouse, we had to look for a suitable solution. 
Once again, it was Mr Wasilczyk who came up with the crucial tip: with an additional pulley, the GEDA MAXI 150/300 can lift weights of up to 300 kilograms. That solved the problem.
Now all we had to do was transport the material in batches onto the platform in front of the manhole at a height of 10.5 metres, which had been further enlarged. The GEDA 1500 Z/ZP Master with side loading was the obvious choice here.
With this combination, we were able to handle the entire material logistics process without any problems with just five people per shift.

3.    How has the interaction between the five GEDA units optimised material transport in and around the boiler?

Thanks to the combined use of the five GEDA units, we were able to optimise the logistics of the scaffolding erection. The project was carried out with fewer staff than originally planned. At the same time, we were able to meet the specified time targets with a sufficient margin. This naturally also resulted in a financial benefit for us.

4.    Which features of the GEDA equipment used have proved particularly effective in this demanding industrial application?

Thanks to its compact dimensions, simple design and a load capacity of 300 kilograms, the GEDA 300 Z Boiler Hoist is the ideal piece of equipment for scaffolders working in boilers and tanks, as well as for outdoor use.
The GEDA MAXI 150/300 is a tried-and-tested piece of equipment whose range of applications is further expanded by the additional pulley. The GEDA 1500 Z/ZP perfectly complements this combination thanks to its versatility and high load capacity.

5.    In your view, what makes GEDA the right partner for complex refurbishment and maintenance projects?

GEDA was the ideal partner for me on this project. With its in-depth expertise, swift processing and reliable delivery, the company played a key role in ensuring that we were able to successfully complete the project. This provides a solid foundation for further successful projects between us.
