Top Loading Arms
The most popular OPW top loading arm used in many applications worldwide.
This versatile arm is designed 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.
- Ideal for applications where variable spotting of the vehicle is common
- Easy to handle, smooth operation
- All flanged construction in for ease of maintenance (available in 3” and above)

- Inverted inlet swivel orientation, model C33RF or H33F, to assist self draining capability available
- Adaptable to tight-fill or closed-system loading with optionally supplied swivels and couplers
