Long Range Hose Loader

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.

Accessories

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.

OPW Loading Systems

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.

Success Story: SI Group

This success story demonstrates how the SI Group Manufacturing prefers OPW Engineered System's Drylock Disconnect Couplers and Adaptors for their outstanding safety features, with virtually no fluid loss and no exposure.

Drylok™ is designed to safely transfer hazardous corrosive, volatile liquids such as acids, solvents and petrochemicals. An interlocking handle averts accidental spills by preventing uncoupling while the valve is open. And, the unit's flat face minimizes fluid loss, further reducing exposure to risk during operation. Drylok™ is ideal for all kinds of hazardous fluids where product loss is a problem, such as high-pressure lines, high flow rates, slurries, and gases.

OPW 790 Series Torsion Spring Adjustiment

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 Counterbalance

New 890 Series High Load Counterbalance from OPW features a high-tension spring for "zero drift" stability when handling heavy loads.
