Side Contact Collector Assemblies for Continuous Systems. 40 Amp Standard Single Mount Collectors. "M" Head "L" Base Type for Systems up to 600 Volts With Straight Runs and Curves to Minimum of 9 Inch Radius. Standard Pigtail Length = 15 Inches. The Collector is a Sliding Contact Type Which Confines the Wear to the Easily Replaceable Contact Shoe. Note: Collectors Should not be Used as Power Switching Devices. The Resultant Arcing may Cause Rapid Deterioration of Both Contact Shoes and conductor Bars. The Contact Shoes are Supported by Insulated Shoe Holders on Spring Loaded Collector Arms Designed to Articulate and Swivel. Collector Arms are Designed to Accommodate a Certain Amount of Movement or Misalignments Between the Crane / Vehicle and the Conductor. However, if Misalignements are Excessive the Collector Could Disengage from the Bar. Poor Collector Installation is the Single Greatest cause of New System Problems. Installation Instructions Should be closely followed to Optimize System Performance and Prevent Problems.
