OPW spring balanced hose loaders are available in both short-range (SRH-32) and long-range (LRH-32) versions. Like counterweighted hose loaders, spring balanced hose loaders are generally stored at horizontal and only slightly upward or downward movement is required to align the coupler with the tank truck adaptor.
The Long Range Hose Loader, in the 4" size, is used in exactly the same manner as the counterweighted hose loader. The major difference being the counterbalance mechanism is a torsion spring rather than weights.
Grounding/Bonding – Suggested for many top/splash loading applications. Available as an option on all Loading Arm designs. Electronic Ground Verification The Civacon model 8030 Ground Verification Monitor is compatible with today’s transport ground systems. The monitor is equipped to provide a permissive signal to allow load rack operation and, if ground is lost, to indicate a non-permissive signal and shut down the loading operation.
Safety Breakaway Coupling Protects your equipment, piping and personnel in the event of an unintended pull-away. A consideration whenever you are making a tight connection to a truck or railcar.
Quick & Dry Disconnect Couplings
With OPW, you have many options at your disposal for your loading arm termination connections. From the original quick-disconnect Kamlok® coupling to our Epsilon™ dry disconnect coupling, we have a coupling to meet your needs. API Bottom Loading Couplers Commonly used for loading Petroleum products, OPW provides several options for loading your Petroleum transports. Loading Valves
All OPW Loading Arms can be customized to fit your specific application requirements. We do offer a series of Standard/ optimized solutions that are commonly specified. These optimized selections can be expedited to meet faster delivery requirements.

The transfer of volatile, valuable, potentially toxic fluids requires highly engineered loading arms, couplers and swivels. OPW Engineered Systems is the global leader in the design and manufacture of products that transfer fluids SAFER, CLEANER, FASTER.
The OPW 790 Series EZ Adjust Loading Arm Spring-Balance permits any one of a full range of spring balance adjustments with a simple turn of the wrench. The 790 is the ultimate user-friendly solution to spring adjustment. With this technology, you no longer have to have the loading arm in the vertical position to make adjustments. In most cases, adjustments can be made from any position.
New 890 Series High Load Counterbalance from OPW features a high-tension spring for "zero drift" stability when handling heavy loads.
