We usually supply GRP (glass-fi ber reinforced plasti c) canti levers, but our producti on includes aluminium canti levers as well.
For longer lengths or higher load of canti lever we off er double canti lever with all needed armatures.
We use special 3kV loop insu- lators to reach second level of Cross-wire suspensions are insulati on within fi xed to the poles by the the cross-wire various hinge types. suspensions.

5 trolley-bus crossinGs & curve clamPs
Trolley-bus crossings and switches allow a transit speed of up to 50 km/ hour.
Curve clamps guarantee smooth passage and higher vehicle speed as well as its easy installati on.
6 You can choose diff erent geometrical soluti on (20°-90°) of TBUS x TBUS crossings. Left and right opti on is available.
Correct type (length) of used curve clamps has large infl uence on the operati on speed.

For roundabout soluti on is suitable use of double switch point controlled by VETRA system with fully automati c operati on.
8 We off er all types of switches in 10° or 20° narrow- angle design and in left / right opti on.
Our 20 years experience in switches producti on makes them highly reliable and in top quality.

9 tram X tbus crossinGs & Kevlar roPes
New type of TBUSxTRAM (15°-65°) crossings without interrupti on of electrical supply is perfectly silent and ensure vehicle’s sustained passage with current.
Vehicle of any directi on can stop wherever within passage of this crossing type and easily start driving again.
10 Supporti ng net made from KEVLAR syntheti c ropes decline undesirable noise which is characteristi c for vehicle‘s moving. Except noiselessness of syntheti c rope during operati on further important advantage is its insulati on.
We produce wide assort- ment of KEVLAR clamps and fi tti ng mate- rial adjusted for insulated syn- theti c ropes.
11 FeedinG & disconnectors
Special assembly of insulati ng rods together with disconnector and motor drive allows simultaneous control of both (plus - minus) polariti es.
We off er complex soluti on of depot control including remote control and no-voltage status alerti ng.
12 Motor drives are suitable for control of disconnectors which are in everyday operati on. The control of motor drive can be local or remote.
