Top Loading Arm
Top loading arms are used to load or unload road or rail tankers. Loading or unloading is done through the manhole on the top of the tanker. Depending on the nature of the product (not dangerous, without any toxic vapors…), the connection may be “open”, this means that the manhole is not sealed. A “Semi-Closed” connection can be made by a cone on the manhole of the tanker. A “Closed” connection is required for all dangerous and toxic products. This connection is made by a flange to the top of the tanker. A cone can be equipped with a vapour hose to prevent the vapors from being released to the atmosphere. Numerous accessories are available to make a loading arm more ergonomic and more effective: press down system, pneumatic up/down system, top level control, safety break valve, purge, drain…etc.

“Opinions are not to be learned by rote, like the letters of an alphabet, or the words of a dictionary. They are conclusions to be formed, and formed by each individual in the sacred and free citadel of the mind, and there enshrined beyond the arm of law to reach, or force to shake; ay! and beyond the right of impertinent curiosity to violate, or presumptuous arrogance to threaten.”
—Frances Wright (1795–1852)
