Actuators for control valves in hydroelectric power plants

Example: Tacen-Kanutrail hydropower plant, Slovenia

The control valve of the hydropower plant is operated by an ADE 50 kN/2550mm electric actuator.



Actuators for swing bridges

Example: Motorisation of the Hitzacker swing bridge in Lower Saxony (Germany)

This structure, installed in 2020, incorporates a 100kN/2300mm actuator to drive the rotation of the bridge.


Actuators for gate valves

Example: Oranjesluizen fish pass (Amsterdam, The Netherlands)

This fish pass is equipped with a 50kN/2550mm knife gate actuator.



Actuators for anti-flood doors and locks 

Example: Anti-flooding door in St. Pauli harbour (Elbe, Hamburg)

This structure, installed in 2009, consists of 8 actuators of 150 kN/2100mm for driving 4 doors (2 actuators are coupled per door).


Actuators for flood gates and locks 

Example: flood barrier Town of Ipswich (Port of Ipswich - England) 

This structure installed in 2019 is composed of 2 actuators of 80kN/1400mm to drive the 2 anti-flooding gates



Actuators for motorisation of bridges and special structures

Example: Actuator for motorisation of Enkeerdbrug (fiets- voetgangersbrug) located at Pont à Loon, Netherlands

This structure installed in 2021 is motorised by 1 actuator (forces and stroke currently under validation) for raising and lowering the deck.
