Loading Arm Description
.1 Loading Arm
The EMCO WHEATON Loading Arms are a movable pipe system for loading or
unloading railroad cars, tank trucks and other vessels. The transfer of fluid is
achieved by either introducing the loading arm into the manhole or making a
connection to the flange of the vessel. Please refer to the general arrangement
drawing for connection details.
EMCO WHEATON wivel Joints and counterbalance mechanisms provide
smooth and balanced movement of the loading arm in all directions. EMCO
WHEATON loading arms are also designed to be self-supporting.
.2 Main Components - Top Loading
Refer to Figure 1 and 2 in ection 3.3
1.
The F-Length provides reach in the horizontal plane. (boom style arms
only)
2. The A-Length provides reach in the horizontal and vertical planes.
3. The B-Length is introduced into or connected to the tank or vessel.
4.
Swivel joints connect piping and elbows allowing the loading arm to
articulate while maintaining a pressure tight seal.
5.
The spring cylinder balances the A-length and provides assisted
movement of the loading arm.
6.
The vacuum breaker introduces air into the arm and facilitates draining
of the loading arm.
7. Handles are supplied to aid in manipulation of the loading arm.
8.
The loading valve is used to start and stop the product flow. EMCO
WHEATON loading valves feature an adjustable slow closing mechanism
to control the rate of closure to prevent line shock.
9.
Other valve types are used to start and stop the product flow of loading
arms for chemical, hot & food products.
10.
A remote control is used to assist in operating the loading valve while
the operator is visually monitoring the fluid level.
11.
The flange or coupler is used to connect the loading arm to the
corresponding connector on the vessel.
12.
A proximity switch (limit switch) can be installed to monitor the position
of the loading arm or the state of the product valve (open/closed).

.4 Main Components – Bottom Loading
Refer to Figures 3 and 4 in ection 3.5
1.
The stand post carries the loading arm. If several loading arms are
standing in a row, the stand post of each loading arm has a different height
to enable you to cross the hoses without collision.
2. The intermediate tube carries the parking device.
3. The F-Length provides reach in the horizontal range.
4. The A-Length provides reach in the horizontal and vertical range.
5. The B-Length is connected to the tank or vessel.
6.
Swivel joints connect piping and elbows allowing the loading arm to
articulate while maintaining a pressure tight seal.
7.
The spring cylinder balances the A-length and provides assisted
movement of the loading arm.
8.
The vent connection is used to vent the loader while filling it with product
or to accelerate draining for maintenance.
9. Use the handle to move the loading arm.
10.
The coupler of the loading arm connects to the adapter at the tank or
vessel.

For loading arms not supplied with a finish coating, the customer is responsible
for painting the arm to provide corrosion protection.
Protect all hoses and cables against rodents. If the arm is to be stored for an
extended period, protect with a suitable preservative. Please contact EMCO
WHEATON for more information.
6 Installation
6.1 Installation of the Loading Arm (E2025 & E2304 shown)
Attach suitable hoisting gear to the loading arm for lifting the loading arm and to
avoid damaging the loading arm.
Danger
During installation of the loading
arm it could turn or fall down
Keep a safe distance from the
loading arm while hoisting
Loosen the transportation locks and remove all packing material. Lift the loading
arm and remove the supporting frames. Mount the stand post or the wall bracket,
if supplied.
Pay close attention to a proper vertical alignment. Lift the loading arm until
mounting brackets align properly. The installation position of the loading arm is
horizontal (see drawing for correct inlet position). Bolt the swivel joint bracket to

the support bearing bracket. Ensure that the slew axis of the boom is in a vertical
position. (previous note only applies when bracket or stand post is supplied)
The inlet flange attachment bolts and nuts are not included in the scope of
delivery. elect adequate bolts and nuts which are suitable for the weight and the
bending moment. Use all attachment provisions.
Connect the flanges and install gaskets at the flanges.
Remove the transport locks from the loading arm and spring cylinder ( ee Figure
5 below).
Figure 5
Install components supplied separately (such as overfill device, parallel guide,
hoses, couplers etc., if applicable). Refer to the loading arm drawing for more
information.
Once installed, move the loading arm and verify that it will hold its position. If the
loading arm slews about its axis, ensure that the mounting flange is level. If the
arm is not properly balanced, adjust the balance of the spring cylinder (refer to
the spring cylinder adjustment manual for procedure). Although all components
have been adjusted to proper values by the factory, minor adjustments may be
required.
Caution
If the loading arm is inadequately
balanced or moves on its own it may hit
persons nearby causing injury.
Adjust arm and mounting flange to suit.
Ensure not to enclose any objects in the system (e. g. tools or bolts). Clean all
tubes before final installation.
The operator of the system is responsible for grounding the system and
protecting it from lightning.
Only persons with the required training and qualification should connect and
maintain the electrical, pneumatic or hydraulic systems. Connect these systems
according to the accompanying diagrams and data sheets.
