Installation Tools/Equipment


  • Belt Clamps: Avoid the problems and potential dangers associated with homemade devices with belt clamps designed to properly secure and clamp a belt for safe conveyor maintenance.
  • Belt Cutters: A properly squared belt discourages mistracking and splice failure, so utilizing a belt cutter that provides a straight cut is paramount to the splicing process. Our Belt Cutters minimize the danger of accidental injury during the belt-cutting process.
  • Belt Lifter: Our Belt Lifter puts an end to pry bars and manual lifting, making a difficult and hazardous job easier and safer.
  • Belt Skiver: A skived belt helps extend splice life, ensure compatibility with belt cleaners with a lower profile, and creates a stronger splice
