Every Roura rotator box is highly configurable, but the first place to start when selecting a model is size, including the physical dimensions and load capacity. Sizing your rotator box correctly from the start reduces safety risks from overloading and improves efficiency by reducing the number of trips needed for any given dumping application.
What Is Your Material Density?
A box sized by cubic yards can easily exceed its weight rating when it’s filled with dense materials, whether that’s castings or steel scrap. Estimate the full box weight by multiplying volume by weight density, then check it against the rated load capacity. Roura offers the same volume (whether that’s 1/2 cubic yard or 3 cubic yards) at different capacity levels to fit different needs.
What Types of Materials Are You Handling?
Likewise, different materials behave differently. Sticky or stringy materials like wire can easily bridge or cling inside the box, and deeper configurations will make the problem worse. Additionally, Roura designs specialty configurations based on how the material is transported, whether it’s liquid in 55-gallon drums or materials in a Gaylord box.
What Is Your Forklift & Rotator Capacity?
Your forklift’s usable capacity with the rotator attachment installed sets the upper limit for the box’s weight (and its contents). A deeper box will push the center of gravity farther out from the carriage and lower the truck’s usable capacity, meaning that a box can still be too much, even if it’s within the truck’s rated weight, if the load center is too far out.
What Is the Maximum Reach & Height?
Verify that your truck has enough reach to empty into your equipment at the location where you’ll use it. Account for both overhead and side clearance; rotator boxes sweep a wide arc, so check that nearby walls, pipes, lights, and roof beams in the dumping area (if applicable) won’t be an issue.
How Big Is Your Receiving Container?
The opening of the rotator box should empty completely into the receiving container without spilling over the edges. Don’t choose a rotator box wider than the dumpster opening; even if you rotate your forklift attachment slowly, it won’t stop spillage.
What Is Your Storage Footprint?
Where will you store the rotator box when it’s not in use? Standard rotator boxes have a square footprint (usually 47” x 47”, with varying height.
What Is Your Fill Rate?
Size your rotator box so it fills in a sensible interval that matches your forklift schedule. You don’t want to undersize, which results in more forklift trips (and annoyed operators), while oversized boxes will take more space when not in use.
