Hydro gates as Eccentric gates

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

• Intake gates
• 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:

Please notice:
⁃ 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.
