This spring balanced hose loading arm offers the same advantages as the conventional “A”-frame loading arm except flexible hose is used instead of rigid piping on the secondary arm. This loading arm can be staggered to achieve crossover and conformance to the API envelope requirements. “A”-frame hose loaders are normally stored in an upright, near vertical position making it possible to load from both sides of the island. In addition to bottom loading, the “A”-frame hose loading arm is often used as a vapor arm in fuel terminals and can be adapted for use in top loading and unloading applications.
