OPW spring balanced hose loaders are available in both short-range and long-range versions. The short-range model has the torsion spring mounted back at the riser, while on the long-range units the spring is located a short distance out on the arm. 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.
This type of arm, in the 4" size, is used in exactly the same manner as the counterweighted hose loader. An exception: the counterbalance mechanism is a torsion spring rather than weights. Four long-range hose loaders with a 114" reach spaced 18" apart will fully cover the API RP-1004 bottom loading envelope.The short-range loader with a 52" reach conforms to the API envelope with three arms installed 24" apart.
