Physical barrier at upper-most level to provide additional safety if access gate is opened and carriage is not present.

Safety Requirements

PFlow installation crews are skilled in applying all safety devices in accordance with OSHA, ANSI/ASME B20.1 code. 

The following guarding is required to meet code:

  • All sides of the unit not used for loading or unloading must be protected by enclosures a minimum of 8’ high and capable of rejecting a ball 2” in diameter at each level. If attached to the edge of a mezzanine or balcony, only minimal enclosure is required because the equipment is guarded by location.
  • In a manual loading application, each unit must be equipped with a safety gate that is electrically and mechanically interlocked with the carriage movement. To protect workers from exposure to moving machinery, PFlow gates are 6’ high. 4’ high at the upper level may be used in some low-clearance situations.
  • Any combination of shaftways, walls or permanent enclosures that provides equivalent protection is acceptable. Fire doors, acoustic doors, finish doors, etc., are acceptable if they are provided with appropriate interlocks.
  • Fire Code Requirements: If a floor is penetrated, your insurance company or local fire authorities should be contacted to determine if a fire-rated enclosure is required.
  • Each Vertical Reciprocating Conveyor application should be reviewed for adherence to all codes.
