Loading and Unloading Arms – Long Range Top Loading Arm with Vapour Recovery System

Loading and Unloading Arms – Long Range Top Loading Arm with Vapour Recovery System, EWFM Supply a range of Loading Arms and Unloading Arms for discharging or filling tank trucks and rail cars. These arms are either bottom or top types of arms. Both types of loading arms are typically made of 3 pipes – respectively called the inner arm, outer arm and drop pipe. The size can be from 1” to 6”. These 3 pipes are connected by swivel joints. Swivel joints are required to provide the flexibility needed.

The Loading Arms and Unloading Arms unfold to get the required working envelope to load or unload the tanker, and the reverse is to retract or get minimal space for parking or storage. Both types of loading arms may be mounted on a column or via a plate to an existing wall. Balancing is needed due to the weight of the piping. Balancing of the arm is by a spring balance cylinder.
