  • Drip Bucket and Bucket Hook:
    A hook on the end of the outboard swivel with a bucket to catch product drips
  • Bonding Straps:
    A hard wired link across each swivel joint to maintain electrical continuity.
  • Balance Mechanisms:
    Arms are balanced by heavy-duty compression spring with 90° of total movement. Alternative balance mechanisms available are gas strut, counterweight, pneumatic and hydraulic
  • Ground Verification Monitor:
    An explosion proof electrical control system to continually monitor static charge accumulation in the vehicle.
    Communicates with the DCS to allow operations to start/carry-on only when the static accumulation is below recommended levels
  • Rack Monitor:
    Where applicable. An explosion proof electrical control system that continuously monitors the high level liquid sensors in a tank/compartment. In the event of a high level signal or a sensor failure the monitor shuts down the loading operation
  • Remote Operator:
    To operate the loading valve manually from close to the outboard swivel of the loading arm
  • Parking Adapter:
    A device to retain the loading arm in it’s parked position
  • Position Sensor:
    Electrical explosion proof proximity or limit switch (s) to advise the position of the loading arm
  • Vapour Recovery:

    • A Piggy Back Hose: Carried by the loading/unloading arm to connect directly with a vapour adapter
  • Parallel Device:
    Maintains the Outboard Swivel in a level position regardless of the position of the Primary Tube.
  • Check Valve:
    Mounted in the Primary to prevent product being drawing back in through the loading arm. Also acts as a pilfering deterrent
  • Stand Post:
    A fabricated stand to which the loading/unloading arm is attached. Most large Top Loading Arms and all Bottom Loading Arms come with a Stand Post
  • Control Valves/Isolation Valves:
    Manual or automated control valve or isolation valve mounted before the inlet to the loading arm or mounted within the loading arm to control flow or act as an isolation valve
