JUNG Rotating Dollies

JUNG rotating dollies are Made in Germany and offer the highest reliability, ease of use and function employing superior technology, engineering, and manufacturing quality. Our machine moving dollies provide stable dependable support for load transport, roll & turn easily, and move loads safely even at the maximum rated capacity. These machinery dollies offer the following features:

Key Advantages:

  • Rotating dollies will roll & turn easily at max capacity, where others would fail to roll.
  • Dollies have 360˚ maneuverability with the ability to move loads sideways & around tight corners.
  • Dollies possess safety capacity above rated capacity.
  • All dolly models sold separately. Mix & match individual rotating skates of same height to fit oddly shaped loads.
  • Slick turning characteristics of specially formulated JUWAmid wheels allow for easy change of direction.
  • Fewer large diameter wheels - compared to using greater number of small wheels - maintains functionality with larger loads.
  • Made in Germany
  • Manufactured by JUNG
  • US based Sales and Lifetime Technical Support
  • Parts available for all products dating back 40+ years.


  • Ideal for moving machines, equipment, and material in confined spaces during installation, maintenance, and relocation.
  • Use rotating dollies for transporting loads on smooth and level concrete, asphalt, or steel plates.


  • Dollies are outfitted with center hole and side slots for mounting options.


  • Manufactured by JUNG
  • Made in Germany
  • For 40+ years


Smaller rotating dollies are outfitted with black JUWmid wheels while higher capacity rotating dollies are outfitted with yellow JUWAthan wheels.


Smaller loads are often maneuvered by hand, so the wheel material is optimized for superior turning and rolling characteristics.

Larger loads must be pushed by a forklift (or other powered vehicle) so rolling and turning characteristics become less important. So, this wheel material is optimized for superior floor protection required with heavier loads.

Both materials:

  • Multiple narrow wheels on the same axle are specifically designed to allow spinning in opposite direction during a turn to reduce friction forces.
  • Wheels are engineered for extremely long life and extremely low failure rating.
  • Use on smooth and level floors only.
  • With sealed ball bearings against contamination with dirt for both inside and outside use.
  • Reliable under toughest working conditions.
  • Wheels provide superior performance and durability over traditional polyurethane, composite, and steel wheels.

Skate Sizes:

  • Wheel size and overall skate height increases with increased load bearing capacity.
  • This assures consistently low rolling resistance and reduces the risk of point-loading wheels.

Optional Accessories:

  • Pulling handles are used to control loads against run-away dangers.
  • Connecting bars provide extra level of protection against slipping of dollies for vital/dangerous loads.


  • Materials including steel and wheel material are specifically manufactured for its use. We do not use untested garden-variety materials.
  • Factory is ISO certified, uses state-of-the-art production tools including welding robots to assure each product meets consistent quality.
  • Each rotating dolly is outfitted with an anti-slip load pad.

Quality Level

  • Made in Germany
  • All products have significant safety capacity above the rated load bearing capacity so all products can be used the maximum rated capacity.
  • All new products undergo long testing period in the lab and in the field before release to public.
  • All products are tagged with a serial number and any defects are traced.
  • All machine moving dollies and skates come with a 5-Year manufacturer's warranty; Exception: All electrical and air-powered products come with a 1-Year manufacturer's warranty.
