Long Range Electrically Heated Top Unloading Arm – Model 2879-TRC

Long Range Electrically Heated Top Unloading Arm – Model 2879-TRC

EWFM supply the Long Range Electrically Heated Top Unloading Arm. This unloading arm gives the greatest reach of top unloading arms for transferring hot fluids such as asphalt, sulphur and bitumen therefore the best flexibility. This arm consists of a horizontal boom assembly that give a wide range of operation on both the vertical and horizontal planes.

As a result this allows truck or rail-car compartments to be unloaded without moving the vehicle or train. As it is a top unloading arm, a hooking drip bucket is attached to the bottom of the tube to catch any excess product that may escape. In this loading arm design there are three swivel joints to ensure a smooth movement, a style 30, style 70 double and a style 40.

For more designs, please head to our loading arm page where you can find a range of Loading and Unloading Arms.
