OPW Engineered Systems
Short Range Hose Loader

Loading Arm Configurations

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.

• Available in 4"
• Available in carbon steel, stainless steel and aluminum
• Choice of flanged, threaded or all-welded construction

BENEFITS:

• Ideal for converting Top Loading installations to Bottom Loading
• Easily adjustable torsion spring
• Easy to handle and move
• Easily meets API envelope requirements with 3 units on 21” (533 mm) centers.
• Easy to operate/maneuver
• For multiple product applications, it can be mounted close to another arm
• Crossover can easily be achieved

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.

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.

• 6400 Series Horizontal Valve – OPW Loading Valves are designed to shut off flow without causing shock in the pipeline.
  • Adjustable closure rate
  • 3” & 4” sizes, Aluminum Construction
  • TTMA Flanged connections
  • Ball Valves (per application/specification)
