Enclosed Conductor Trolley Bar for Cranes

The HFP 56 system is a powerail,protected from contact ( IP 24 ),for indoor and outdoor plants.The are conductor lines in a rigid green PVC housing with different copper cross sections for rated currents of 35A-170A.The current collectors,running in ball bearings,are guided by the housing.The main is transferred by spring-stored carbon brushes.Technical dataElectrical properties:Max.current(A): 35 - 50 - 65 - 80 - 100 - 120 - 140 - 170Max.voltage(V): 600Conductor cross section(mm2):8 - 10 - 12 - 15 - 20 - 25 - 35 - 50Leakage-distance(mm):35 - 35 - 35 - 35(or33) - 33 - 33 - 33 - 33Resistance(Ω/km):1.944 - 1.656 - 1.321 - 1.137 - 1.011 - 0.713 - 0.522 - 0.337Leakage resistance:CTI600-2,7Dielectric strength: 30-40KV/mmMechanical properties:Flexible strength:75N/mm2±10%Tensile strength:40N/mm2±10%Temperature range:Common Housing: -30oC up to +60oCBAYBLEND Housing: -20oC up to +115oCCombustibility:Flame retardantSelf extinguishing:class B 1-no flaming paricles,self-extinguishing.Resistance to chemicals:+45oCGasoline:Sulphuric acid 50%Mineral Oil:Caustic soda 25% & 50%Grease:Hydro-chloric acid,concentrated.HousingColor green,plastic housing for 4 conductors.Standard section 4 m.Other sections are available.The ground conductor is identified by international color code.Phase reversing prevented by design of the collector and housing.CouplingsThrough plastic joint caps.Feed SetsLine feeds or end feeds.End capsThe open ends of the powerail are closed by end caps for HFF.HangersStandard brackets for powerail attachment to crane girders are available.Powerail with sliding and fixpoint hangers.Standard distance between suspension points for indoor and outdoor installations:1200mm.Expansion during temperature fluctuationThe Expansion sections arerequired to compensate the different expansions between copper conductors and steel-or concrete structures,in varyingtemperatures without interrupting electrial power.Expansion joints are used when the Powerail length between feeds,curves,switches or other fix points is exceeding 20m.Install one expansion joint every 100m.Anti-condensation sectionsThese sections are used for transfer of the Powerail to outdoor areas to avoid condensation.The Powerail is not separated electrically.SectionalizingAvailable as air gap version (5mm),where the collector carbon bridges the gap,e.g.for mains.Also available as insulating piece version (35mm).In this case the insulating piece is longer than the carbon and each Powerail section can be separated electrically,e.g. for control.Current collectorsThe current collectors are made of re-inforced polyester fiberglass,for high strength and light weight.Spring loaded carbon brushes maintain uniform contact.Connecting cables and hinged or flexible towing arms included.Double Current collectors for transfer applications and higher amperage.Maintenance--After installation,Make sure that the sliding hangers are straight (in a perpendicular position) after nuts have been tightened to guarantee free sliding of the powerail.The powerail must be installed exactly straight and parallel to the machinery track.--Before running the powerail,Check the system for esay running of the current collector trolleys,i.e.there may be no resistance by an excessively narrow slot or pull by the connecting cable.--Every 3 up to max.12 months,-depending on the frequency of operation and travel distance-,check the carbon brushes and mechanical componets for wear and replace them if necessary.
