Bottom Loading Arms
Introduction
Bottom loading arms are used both for open loop and closed loop fluid transfer.Standard bottom arms are provided with five swivel joints and a multi-spring balance cylinder. A second balancing system can be applied to keep the connecting pipe in a straight horizontal direction, in case the connecting pipe is equipped with heavy items such as ball valves, breakaway couplers or dry-break couplers. Bottom loading arms are mounted to a self-supporting column with locking facilities.

Top Loading Arms
Introduction
Top loading arms are designed to load (or unload) tanks by the top. These tanks can be either small containers (barrels), rail- / road tankers or ISO containers. Standard top loading arms are provided with four swivel joints for the product line and a balance system (counterweight or multi-coil spring cylinder). Top loading arms can be equipped with a large number of accessories. Depending on the requirements involved, the design can vary between standard Kanon solutions and fully customer specific.
