Minimel Lynx LOWS - Manually triggered radio warning system

Brief information

The Minimel Lynx warning system warns people in the vicinity of the track of approaching trains. When used as a "Lookout Operated Warning System" (LOWS), the detection of train movements by persons (pre-warners) is done manually. The HSF-L handheld transmitter reports the detected train to the EZE-L control centre, which triggers the acoustic and visual warning. The departure of the train from the construction site is also acknowledged manually at the EZE-L control unit and the warning is cancelled.

Minimel Lynx is used as a LOWS on construction sites with small dimensions, such as maintenance work, moving construction sites, vegetation maintenance or switch conversions.

About the machine

Automatic attention monitoring

The patent-pending vigilance circuit monitors the operator's attention by analysing the movement pattern. In case of inattention a warning is given. The operator is not distracted in his activity by repeatedly pressing a key.

Collective and individual warning

In the case of collective warning, the system warns all persons present together. In the case of the individual warning, each person wears his or her own warning device and is warned only personally.
The radio-based EWK-L, the wired AW126-L and the compact EWK-L-A are available as collective warning devices. The individual warning is given via the EPW, which is worn on the body and equipped with headphones.

Maximum configuration

A maximum of 10 EWK-L radio-based warning devices can be controlled from one EZE-L control unit. If a longer warning chain is required, the EWK-L warning device can be extended with up to 16 wired warning devices AW126-L, which gives a maximum site length of 450 m. The number of individual EPW warning devices is not limited.
