When deciding upon a conceptual design for road and rail tanker loading stations some basic principles need to be considered. Top and Bottom loading each have their own advantages, which can benefit the installation when correctly applied.

Features and benefits of both Top and Bottom loading arms are provided in later sections detailing these products more fully.

In general terms, however, the basic design data needed for a loading station includes the following, all of which may not be applicable in every case.

Design data may include:

1. Type of fluid; temperature, pressure

2. Viscosity in normal/abnormal condition

3. Capacity in m3 or tonnes/hour

4. Multi-product loading

5. Number of different fluid media at one loading station

6. Number of loading arms filling simultaneously at one tanker

7. Required level of operator safety

8. Environmental requirements; i.e. vapour return/recovery overspill protection

9. Integration with metering or weighbridge facilities 

The following is applicable irrespective of whether top or bottom loading, or even a combination of both is specified.

A common requirements for all fluid transfer systems is that contact with man and environment should be avoided.   This demands no leakages, no-spill connect/disconnect, self draining systems, lockable stored position, etc.

Hundreds of user friendly and easy to operate OUR loading systems are in use today in highly demanding applications.

This brochure provides the tools to enable the correct solution to be selected.

BALANCING

Loading arms should be balanced such that minimum weight is borne by the operator irrespective of the position of the arm.

Balancing starts with the loading arm design; forces working on one end of the arm are to be compensated for by traditional counterweight, or more advanced spring balancing, at the other.

The maintenance free balance cylinder is designed for applications which demand less space and can be combined with hydraulic or pneumatic operation.

OUR spring cylinders with multiple compression spring packages, can be adjusted to meet changes in operating conditions. Compared with conventional designs, OUR adjustable spring cylinders excel in terms of safety and long life.
