Our main product is the patented gate known as the Eccentric gate, a product designed and produced for a world wide market.
Described by location
Eccentric gates for upstream installation
(i.e. inside a reservoirs dam wall)
Eccentric gates for downstream installation
Eccentric gates to be mounted inside a slot in dam wall
Described by function
Bottom outlet gates
Eccentric gates for spillways
Automatic closing gates in case of downstream bursted pipe or other emergiencies
Eccentric gates for replacement of stoplogs
Gate which has replaced Stop Logs:
⁃ Easily manouevered by one person only – rolls up with extremely low friction
⁃ How sediments are removed from sand banks inside dam
⁃ How easy the gate closes - only by its own weight. No gliding gates can perform like this.
Described by sizes
All combinations of width and height from 500 mm up to 5000 x 5000 mm.
Described by maximum load
Highest load capacity up today: 108 metric tonnes
Described by features
Gates without gaskets vulnerable for wear and tear
No need for replacement of gaskets under normal use
Gaskets can seal direct against a concrete wall
Up to 10000 or more cycles up/down without any problem
Low demand of manoeuevring forces up and down
Easy installation within wide tolerances
Extreme capacity against corrosion; stainless steel or epoxy coated surfaces
Manoeuvering equipment for Eccentric gates
Manual and hand driven chain hoists or electrical operated hoists
Hand driven hydraulic pumps- or electric driven hydraulic pumps + hydraulic cylinder
Electrical driven screw jacks or electrically driven trapezoidal screws
Our own Balance Lock enabeling mechanical long term holding of Eccentric Gate- and quick release of gate to rapid closing in emergency situations with a low power demand: 70 watts electrical power from a battery in a period of 10 seconds can close a gate with permissible weight up to 5 tonnes.
