Easy reversibility (SA version)
With the automatic release (SA) version of the HYDRO models, the gate can be moved with no effort when the motor is stopped. Unlike the reversible models (non SA), because of the special automatic release system, when the operator is stopped, the gate can be opened and moved extremely easily, without having to exert any pressure. The electric lock must be used.

  • Reliability and high-quality materials

    Chrome-plated steel shaft and anodised aluminium profiles ensure maximum resistance to atmospheric agents. Brass bypass valves are used for greater regulation, ensuring maximum crush-resistance.
  • Very easy to install and maintain

    The terminal boards built into the oil cap make installation faster and easier. It is also easy to replace the power cable and control the oil level even when the operator is already installed.
  • Perfect stroke adjustment

    The adjustable front spherical joint enables perfect adjustment of the stroke, the ideal solution for systems on gates that are not perfectly aligned.
  • Self-alignment

    The rear pivot joint makes installation easier, making up for any lack of alignment of the gate.
  • Safe and smooth manoeuvring

    The adjustable hydraulic slowdown in the closing phase ensures silent and very smooth manoeuvring. Avoiding strong impacts against the mechanical stops also reduces the risk of breakages.
  • Top performance

    The new electric motor ensures excellent performance, greater thrust and even more intensive use.
  • Personalised key-operated release

  • Bio Oil

    The very viscous oil ensures excellent performance even in low temperatures, reducing component wear to a minimum.
