Below Ground Systems

770 underground electro-mechanical operator

A NEW TECHNOLOGICAL THRESHOLD
The underground system is the new way of opening and closing residential gates with leaves of up to 2.5 metres in length. As is completely invisible, it does not change the appearance of the gate.

ELECTRONIC SAFETY
Anti-crushing protection is ensured by an electronic device installed on the 410 MPS - 450 MPS equipment, which directly controls drive torque. In case of an emergency, manual operation is assured by a special lever release system with customised key, accessible from both inside and outside.

TOTAL EFFICIENCY
The 770 model design includes a casing to house automated systems for gates of up to 500 kg per leaf, making installation simple. Corrosion-proof coating highly resistant to atmospheric agents, absolute weather-proofing, operator in protection class IP 67: all these are plus points in addition to the undoubted advantages of long-life and safety assured by electro-mechanical technology.

LOW MAINTENANCE
When maintenance is necessary, the operator can be simply removed from the foundation box without removing the gate leaf.
