LTܲ
The safety light grid for goods lifts
The safety light grid LTܲ serves as a replacement for cabin doors of goods lifts with a travel speed of no more than 0.85 m/s. Basis for this is the resolution of the German Lift Committee (Deutscher Aufzugausschuss - DAA) no. 6/34, which is fully met. The proven LTܲ system is easy to integrate in all existing lift control systems. And accompanied by a clever mounting kit and adjustment auxiliaries, it is convenient to use. The integration into the respective lift control system is largely identical, since only signals are used which are available in all control systems.
With and without edge prevention
LTܲ without edge prevention(simple version)
The LTܲ without edge prevention can be used in cases in which the lift is already provided with a safety circuit or a safety switch monitoring the unlocking zone of the door, i.e. this includes all hydraulic lifts and lifts with the function „doors opening early“.
LTܲ with edge prevention(full version)
If the light grid is interrupted shortly before reaching the designated landing and within the interlocking release zone of the door the lift must not stop but continue the last centimetres of its travel so the lift cage comes to a flush level stop. This prevents the development of a dangerous edge (stumbling edge). For this purpose the LTܲ with an integrated edge prevention is provided with a safety circuit monitoring the unlocking zone of the door and, in connection with other signals of the control system and the light grid, preventing the development of an edge.
