Other technical characteristics
Manhole tops are constituted by triangular lids provided with:
- hinge, in order to facilitate the opening/closure operation;
- hold of lids on the frame, in 3 points, in order to avoid the noise;
- in addition to the lock with security key, a "safety block" exists applied on the frame, in which, starting from an angle of 90°, the accidental closure of each lid is prevented.
The innovation introduced by ELETTRA.COM on manhole tops is to work always with two opposite sides, free from lids. This make safer and easier the cable laying or recovery operations.
