The results of
poor quality
Similar products sacrifice quality for cost. Copied parts are welded together into a product without any understanding, engineering, R&D and testing capabilities. Unreliable garden variety materials are used in building the products, putting a break-down of the equipment at risk. The cheaper construction may result in frames bending from impact loading or axles snapping under load. Customers may constantly need to replace parts to keep the products in operation. Look-alike products may be advertised at higher capacities by eliminating or reducing safety capacities. Knock-offs claim higher capacity while exerting so much weight onto the same footprint that the rollers will drag behind instead of actually rolling.
Manufacturing Technology
Old: Welded box frame

NEW: Steel bending wrap-around frame


Our Definition of Load Capacity goes further than just working safely below
the break point:
The more weight is exerted onto the dolly’s footprint, the higher the break-out & rolling resistance becomes until too much weight causes the rollers to drag behind, making changing directions impossible. The maximum capacity at which a roller still turns is limited by the pressure exerted onto the footprint (aside from the component strength). That means a 2 ton rated roller may stop turning at 1 ton of weight. Be assured that you maintain “easy rolling” and “easy steering” at maximum capacity with our dollies.
Safeguard
Old: Wide loading platform endangers overloading of outside wheels if weight presses down one sided:

NEW: Center loading platform guarantees equal weight distribution across all rollers:

Ease of Use
Old: Connecting bar through center required dollies to be pulled out from underneath load for adjustments:

NEW: Connecting bar on outside allows for adjustments while dollies are underneath the load:

The factory employs state of the art robots in the manufacturing process to assure that every product meets the same quality standards. Steel bending technology has replaced the welding of box like frames to eliminate untrustworthy welding seems.
All products are CE certified.

We don’t use garden variety materials. Materials are specifically formulated, tested and engineered in JUNG’s research and development. Materials are engineered for:
• High Strength
• Ease of Use
• Durability under the greatest strain
Each component, steel frame and aluminum composition is built with state of the art technology.

Dollies: Our advertised load capacities are safe working load limits. At maximum capacity you operate well below the break-point AND maintain easy rolling. A safety factor will protect against limited temporary overloading due to impact loading or unexpected shift in weight.
Jacks: Each jack comes with a test certificate that it has undergone a static load test. The capacity rating is valid for lifting with the toe as well as the top loading plate. An overload protection valve will protect the user from picking up too much weight.
