Bonding Straps
A hard wired link across each swivel joint to maintain 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
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 Return
Separate 2” SS vapour return hose
Piggy Back vapour return hose
A vapour hose is carried by the loading arm and connected to the tank vapour valve at the same as the liquid valve(s) are connected
Leak Detection System
Monitors each swivel joint for signs of primary seal failure to give early warning of a potential leak to atmosphere
Stand Post
A fabricated stand to which the loading/unloading arm is attached. Top and Bottom loading/unloading
Outboard End Connections to suit the application
Hammer Union, Dry- Gas Couplers/Adapters, Lap Flange connections
Axial Swivel Joint
Enables an additional plane of movement to allow the use of a rigid drop tube with a vertical connection to the tank
Purging Points or system
To allow an inert product to clear out any remaining product in the arm
Breakaway Device
In the event of a vehicle drive away the Breakaway device with shear and seal the connection to the loading arm and to the vehicle
Remote Shut Down
Spring closed, air open shut off valve activated remotely
Parallel Device
Maintains the Outboard Swivel in a level position regardless of the position of the Primary Tube.
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
Sight Glass
To be able to visually witness what is in the loading arm. Usually mounted before the inlet flange
