Purpose-built for the Yamaha AvantGrand N3 and N3X, along with select versions of the Roland V-Grand digital piano.
The Yamaha AvantGrand N3 and N3X are unlike any other digital piano on the market. With a true grand piano body, three angled legs, and a weight of 360–440 lbs, standard digital piano dollies simply won't fit. The Jansen J4002 is engineered specifically for this instrument, cradling each leg individually in a three-arm spider configuration so the piano moves safely, rolls smoothly, and stays put when it needs to.
Manufactured in the United States by Paul Jansen & Son, the J4002 is built to the same heavy-gauge steel standard as every piece of Jansen piano moving equipment — designed to last as long as the instrument it supports. Used by universities, conservatories, performance venues, and discerning home users.

Why Purchase the Jansen J4002 N3 Digital Grand Piano Dolly
- Purpose-built for the N3 chassis. Three precision-fitted arms mirror the N3's angled leg positions — no makeshift adapters, no universal frames that don't quite fit.
- 24½" and 32" steel sleeves. The dual-sleeve arm design spans from the center hub to each leg precisely, keeping the piano balanced and stable during movement.
- Three heavy-duty swivel casters. Ball-bearing wheels roll smoothly across hardwood, tile, and low-pile carpet without marking or gouging your floors.
- Standard L-Bend brackets at each leg. Engineered brackets cradle each leg base securely, preventing lateral shift during transport or play.
- Heavy-gauge steel with black powder coat finish. Built to support a piano exceeding 460 lbs without flex, warp, or failure over years of use.
- Permanent installation ready. Once assembled, the J4002 can remain under the piano indefinitely — ideal for homes, schools, churches, and studios that reposition the piano regularly.
- All hardware included. Every bolt, nut, and cup required for complete assembly ships in the box. No hardware store run needed.
- Made in the USA by Jansen. The same craftsmanship behind Jansen benches, dollies, and piano accessories for over 50 years.
