4 General information Conductor rails UNILIFT-ULA are designed for powering mobile receivers, mostly lifting devices like cranes and hoists. However, they can be applied for many other types of machines. Conductor rails UNILIFT-ULA are made in 4-pole version for nominal currents 35, 50, 80 and 100A with already mounted copper stripes. They are equipped with innovative bolted joint system (UNILIFT patent pending), providing fast, easy and certain connection. The construction of UNILIFT-ULA takes into account the difference between thermal extensibility of copper wires and PVC housing. Conductor rails UNILIFT-ULA ensure safety and reliable exploitation. Before installing the conductor rail line, be sure to read the installation guide available on UNILIFT website Elements of the conductor rail supply line Line section Covering flange End feed Current collector with connecting cable Sliding hanger Fixing hanger Towing arm Support arm with girder clips End cap
