The concept has the following basic principles:
• The motor and pump are combined into one device which acts as a piston in a fluid-filled cylinder of solid material.
• The cylinder and piston are formed of a flexible material which makes a movement when filled with water. The flexible material can also include a pump function, so that the structure, e.g. in the form of a tube with cylindrical or tapered sides, includes all the functions: pump, cylinder and piston.
• A simple mechanical hold/lowering function that eliminates valves and switches.
• A combined formwork and reinforcement principle which allows a pit to be excavated with a minimum of excavating formwork and casting work without the use of sheet piling.
We have developed a very simple water-based low-pressure hydraulic system that can be used:
• Wherever there are environmental challenges with traditional oil-based hydraulics; e.g. in the food industry
• Wherever there is no need for hydraulics based on high pressure.
• Wherever there is a need for high operational reliability, minimal maintenance and little wear.
• Wherever you want a cheaper solution that meets the same requirements as traditional hydraulics.
The application areas are numerous, and so far we have focussed solely on the product areas: lifts, parking and waste systems.
These solutions can now be offered cheaper, better and in combination with a basement, even in areas where no solution was previously possible.
A combined formwork and reinforcement principle which allows a pit to be excavated with a minimum of excavating formwork and casting work without the use of sheet piling. The principle can replace sheet piling with rammed iron sheets. In this way there can be a reduction of the construction costs and disturbance in the form of vibration and subsidence damage.
The formwork and reinforcement principle can be applied to other types of structures below ground.
