Locking devices

Vice locking device and switch rail spacer device

It is a portable safety device equipped with an FS-type key lock that allows ensuring normally centralized switch when it is inefficient.

The locking device is untrailable and, due to its emergency nature, cannot be engaged by the train at a speed exceeding 30 km / h.

Turnout locking device (DBD)

It is a safety device equipped with a key lock, permanently placed on a turnout, which, in case of need, allows, with a simple manual operation, the locking in main line position or branch line position of the turnout itself, in place of vice clamps and related wedges or spacers.

The turnout locked by DBD cannot be engaged by the train at full speed if the electrical control is missing and the turnout mechanical locking cannot be ascertained.

Key locking device + Detection rods

It is a safety device equipped with a lock with one or more FS-type keys that is applied to switches equipped with a manual point machine. It is connected to the switch rail via a sliding bracket and a detection rod.

It allows verifying the turnout mechanical locking, that the switch actuation is carried out in a complete and regular way and, once the key is removed, it prevents a subsequent actuation of the same.

The key locking device can be trailable or untrailable.

It can be equipped with an electric efficiency control (CEF) which electrically checks both the position of the turnout switch rail and the efficiency of the switch itself, also transmitting any trailing to the cabin.

Universal switch rail locking device

It is a safety device equipped with a padlock that allows immobilizing the switch rail of a turnout from which a track that is not in operation or used occasionally or exceptionally. In these cases, the turnout is immobilized in the position relative to the track admitted to normal circulation.

The turnout equipped with a universal switch rail locking device can be traveled at full speed.
