OPW offers a range of loading arms and related equipment for top-loading. The two most popular configurations are the Scissor Type and the Long-reach type, both of which are detailed below.
At Assentech we work closely with OPW to ensure the arms we provide are of the best configuration for their requirement, carrying out site survey and installations as required.
The scissor type is the most common type of arm used in top loading applications worldwide.
This versatile design is specifically for top-loading installations where a variable operating range is required. The secondary arm rotates 360 degrees in the horizontal plane providing a spotting allowance of up to twice its length.
Commonly used to handle high flow rates and to withstand rough usage in tank-truck loading applications, the scissor type arm is also a good choice for railcar loading applications where cars are frequently mis-spotted.

This popular OPW top loading arm is specifically designed for applications where smooth handling and a wide working range is required, particularly useful for top loading of railcars or multi-compartment tank trucks.
The boom is supported by a high-quality pillow block, allowing for maximum flexibility and smooth operation combined with a significantly longer reach. Both boom and arm can be folded back against the gantry for convenient, compact storage away from the traffic flow.
Commonly used to handle high flow rates and withstand rough usage in railcar and tank-truck loading applications, a stable construction is guaranteed and a supported boom allows many optional accessories to be mounted.
