The DymaxRail Rotating Quick Coupler gives your Gradall excavator full 360° rotation for railway maintenance work. Because the excavator’s boom already tilts 220°, you skip a traditional tiltrotator’s weight and cost.

Finkbiner Equipment, a Gradall dealer in Illinois, outfitted a new XL4300V with the Dymax rotating coupler and tested it with the Local 150 training facility.
On a Gradall XL4300V, the Dymax rotator reaches more working angles without repositioning the machine.
| Yes. The DymaxRail Rotating Quick Coupler adds full 360° continuous rotation to Gradall excavators, running on the machine’s factory auxiliary hydraulics. It carries no tilt of its own—your Gradall boom already tilts through its full range, so the coupler supplies the one motion the boom can’t. |
| A tiltrotator adds both tilt and rotation. On a Gradall, the boom already delivers tilt, so you’d be paying for—and carrying—a function the machine already has. A rotating coupler adds only rotation, which is the piece the boom is missing. Less weight, one auxiliary circuit, lower cost for the same positioning freedom. |
| It fits 14-18 ton Gradall excavators, with a Cat A Link (65MM) compatibility option. Send us your Gradall model, and we’ll confirm the fit before you order. |
| One. It runs on a single auxiliary circuit and handles up to 5 ports at 40 GPM through a custom Dymax proportional valve for fine control. |
| Your standard Gradall attachments, through the hydraulic pin-grab coupler. A bolt-on toolbar interface also takes rail tools, like a ballast rake, clearing blade, and lift hook (sold separately). |
| Your dealer installs the control group from the coupler to the cab using a wire-cable kit, plus drain and jump lines. That’s where the proportional valve and in-cab control get wired in, so plan the install through your Gradall dealer or contact us for the nearest one. |
