- Drip Bucket and Bucket Hook:
A hook on the end of the Drop Tube and a bucket to catch product drips - T Deflector:
A ‘T’ piece fitted to the end of the Drop Tube to deflect the flow as it enters the tank - Cone Deflector:
A Cone fitted to the end of the Drop Tube to spread the flow
evenly as it enters the tank - Drop Tube Handle:
A manual handle on the Drop Tube for handling the
loading arm - 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
apex of the loading arm - Parking Adapter:
A device to retain the loading arm in it’s parked position - Parking Adapter and Drip Collection:
A Parking funnel attached to the
loading rake with a drain pipe to a central collection point - Position Sensor:
Electrical explosion proof proximity or limit switch (s) to
advise the position of the loading arm - High Level Detection:
Electrical explosion proof sensor to advise when the
liquid has reached a predetermined point - Vapour Recovery:
- Vapour plate and vapour hose:
Mounted on the Drop Tube of an
open dome fill operation to divert most of the displaced vapours from
the tank away from the loading area. Usually includes High Level
Detection - Vapour Cone and vapour hose:
Mounted on the Drop Tube of an
open dome fill operation to divert the majority of displaced vapours
from the tank away from the loading area. Always includes High Level
Detection - Piggy Back Vapour Hose:
For Tight Fill operations, a vapour hose is
carried by the loading arm and used to divert all the displaced
vapours away from the loading area
- Vapour plate and vapour hose:
- Telescopic drop tubes:
To enable the product to be dispensed in to the tank
at the lowest level possible. Also used for continuity between the loading arm
and the tank. Manual and powered - Parallel Device:
Maintains the Drop Tube is a vertical position regardless of
the position of the Primary Tube. Common use with Vapour Cones - Hold Down:
An assembly to provide a physical lock for when the arm is in
the lowered and loading/unloading position. Recommended on Variable
Reach Loading Arms - Check Valve:
Mounted in the Primary to prevent product being drawn back
in through the loading arm. Also acts as a pilfering deterrent - 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. Most large Top Loading Arms and some Bottom Loading Arms
come with a Stand Post - Outboard End Connections to suit the application:
Hammer Union, Dry-
Break Couplers/Adapters, Cam and Grove Couplers and Adapters, Lap Flange
connections - Purging Points or system:
To allow an inert product to clear out any
remaining product in the arm
