JUWAmid Wheels

Superior turning performance and durability over traditional

nylon, polyurethane, composite, or steel wheels

Wheel Technology & Construction		Main Characteristics
JUNG rotating dollies are outfitted with black JUWAmid wheels. This wheel material is superior in its performance characteristics - i.e. it turns and rolls more easily - over any traditional nylon, composite or polyurethane wheels for the intended use. Why? Rotating dollies are designed to change direction on a dime or circle in place which requires the wheels to also spin and turn in place. Furthermore, when the rotating dollies are first positioned, the wheels may point in various directions. To get the load rolling, these wheels have to all spin and align into the direction of movement. This initial resistance is called "break-out resistance" and it is significantly higher than on standard dollies that already have all wheels already pointing in the same direction. Under heavy weights, traditional wheel materials exhibit a so called "rubber effect" during maneuvers. The friction between the wheel and the floor is so great that turning and "starting-to-roll" operation becomes very difficult and it significantly reduces the ease of movement. JUWAmid was developed to reduce this resistance. The material is based on a polyamide compound and further chemical engineering of the composition resulted in a wheel that is very slick (like touching ice). This characteristic reduces the rolling resistance and the break-out resistance to make it roll and turn easily. This makes the overall manhandling effort required to move multi-ton loads very easy and it sets the performance from other products apart. The material formulation also took into consideration the need to keep the wheel from marring, marking and damaging floors and the material is resistant against embedding of debris. JUWAmid is exclusively available on JUNG rotating dollies. Ball Bearings JUNG wheels are outfitted with sealed ball bearings to prevent any contamination from sand or dust that would result in a failure of the bearings. Furthermore, standard ball bearings are not very uniform causing unequal load distribution and high failure rates. JUNG only employs precision ball bearings with low tolerances to assure constant even load distribution. Design To further improve the ease of turning, the previously used wide wheels have been replaced by more narrow, side-by-side wheels that now have the ability to turn in opposite direction during tight turns. Side-by-Side Wheels to Reduce Friction JUNG moved to a more narrow wheel size to allow wheels to rotate in opposite directions during turning. this greatly reduces the turning resistance compared to using wider wheels. White JUWAmid Wheels Available The standard black JUWAmid wheels are also available in white. White wheels turn dark from picking up dust so the white wheels usually do not stay white. We consequently recommend the standard black wheels. SPECIAL ORDER Please note that white JUWAmid wheels are special order and additional lead times apply. Upgrade to Yellow JUWAthan+ Wheels Black JUWAmid wheels are recommended and come standard on all rotating dollies. However, customers that need extremely high floor protection can order the rotating dollies with yellow JUWAthan+ wheels (standard on all our other types of dollies). SPECIAL ORDER Please note that yellow JUWAthan wheels are special order and additional lead times apply.		Specially formulated material for optimal maneuverability: Slick-to-touch material for spinning in place, with reduced "rubber" effect on floors for easy change of direction. Precise turning without additional need for aligning by hand. Low man-handling force required to push-pull in confined spaces Non-floor damaging, non-marking Reliable under toughest working conditions

40+ Years of Proven Quality - Made in Germany since 1972

You've probably heard this statement before: "We promise the highest quality!" What exactly does this promise mean? In our case, it means that our products have been designed, developed, made, and relentlessly improved in Germany for more than 50 years. Technology A professional in-house engineering team constantly works to improve our products. We aim to enhance the ease of rolling, durability, and ease of use. This includes making tiny adjustments that may only refine the rolling or lifting friction by 0.1 percent, but these specific modifications accumulate over 50 years and have lead to vastly superior performing products! We often work on maximizing features that cannot be seen, like heat dissipation of temperature increase during rolling under huge turning forces. All aspects of our dollies, skates, and jacks are analyzed and re-engineered to make the products more efficient. Testing In our in-house testing ground, we test materials, parts, and product prototypes. Every new product is then evaluated by professional machinery movers in order to detect weak points in the prototypes or parts. Any discovered deficits are then fed back to engineering. Manufacturing Many companies move their production overseas, but JUNG carries on to produce products and components in Germany, and also invests in its manufacturing plant in Germany . We employ robots in the manufacturing to guarantee consistent quality among every single product. Even though other companies nowadays increasingly advertise 'engineered in Germany' - which in fact means built in another place, our products continue to be Made in Germany. Precision This means that every product and component is manufactured to precise dimensions and precise shape. It furthermore means that every product and component is precisely the same. When a product or component is exposed to the extraordinary forces of multiple tons of weight, any variance from the exact sizes could lead to product breakdowns. Case in point: If the diameter between balls in bearings differs even a bit, the forces will be unevenly distributed, which will sooner or later lead to failure. Another example: If the structure is warped even by 0.1 %, then under load, it twists, which may in the long run lead to cracks. This accuracy can only be attained through state-of-the-art precision manufacturing processes. Low-cost parts can lead to breakdowns, therefore we only employ high-quality components, and each product is exactly the same, and produced to exactly the same production standard. Conformance to Safety Principles Our products are put to the test to meet the most recent U.S. safety standard ASME B30.1. This standard specifies the load bearing valuation and safety capacity demanded by OSHA requirements. JUNG skates are really the only load moving skates in the United States that comply with these specifications. All jacks are tested to comply with ANSI B30.1. All skates can just be tested to capacities of 16 tons. Larger sized dollies and skates cannot be tested, but are made to comply with the same or higher safety standards. Because of its manufacturing process we can guarantee that each product is identical (and does not vary because it was cut, drilled, and welded by hand). Our products may well be issued with certificates of compliance or certificates of conformity (COC). Traceability by Serial Numbers Every product is marked with a serial number. This identifier is associated with the item's material, components, and manufacturing batches. Every part failure can be tracked back to the production batch to determine the underlying cause. This quality assurance program guarantees that deficiencies are wiped out over the years, so that the products get ever closer to absolutely no defects. No other machine skate and toe jack producer has implemented such an advanced quality assurance program. ISO The factory's total quality management system is certified to ISO 9001, which ascertains that customers are provided with continuously improved quality items, and that all products achieve statutory and regulatory prerequisites. More Expertise Provided to the Customer Over 40 years of working experience have provided us with a vast technical knowledge base in the field of heavy load moving. We strive to transfer this skills onto our customers, and aim to make this knowledge accessible on our internet site and over the phone. Customers can call us and discuss their problems with our technical engineers. We have confidence in supporting the potential customer before the purchase, providing support to the client during the operational phase, and providing assistance 10 years after the purchase date. Our Goal is to Help You in Any Possible Way! Combining all aspects, our products and customer service are supreme in quality over any other machine skate or toe jack on the market today.		Reliability
		Our products are used to lift and transport nuclear reactors and nuclear waste. To a small business this reliability and dependability is equally important as a product failure can be equally devastating. We supply the same product quality to small, medium and large organizations.
		The Results of Poor Quality
		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 economical variety materials are used building the products, putting your equipment at risk for a break-down. 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 wheels will drag behind instead of actually rolling.
		Our Definition of Load Capacity
		Our definition of Load Capacity goes further than just working safely below the break point: The more weight is exerted onto the skates's footprint, the higher the break-out & rolling resistance becomes until too much weight causes the wheels to drag behind, making changing directions impossible. The maximum capacity at which a wheel still turns is limited by the pressure exerted onto the footprint (aside from the component strength). That means a 2 ton rated wheel may stop turning at 1 ton of weight. Be assured that you maintain “easy rolling” and “easy steering” at maximum capacity with our dollies and skates.
		Honesty & Trustworthiness
		We aim to completely educate our customers about the advantages but also about the disadvantages, considerations and limitations of our products. We do not overpromise.
		Professional Engineering
		All products are designed by JUNG’s full time engineering team. Besides continuous improvements to functionality and strength, the products are optimized beyond what the customer expects. For example: The dollies and skates are designed for heat dissipation to counter possible weakening over time as high temperatures build up from the enormous friction forces. Internal technology is employed to protect against impact loading and design considerations are given to chemical and environmental resistability. German engineering means test and design for every detail.
		State of the Art Manufacturing and Materials
		The factory employs state of the art robots in the manufacturing process to assure that every product meets the same quality standards. All products are manufactured in house in Germany. Manufacturing process ISO 9001 certified.We don’t use standard commercial readily available materials. Our materials are specifically formulated, tested and engineered in JUNG’s research and development. Materials are engineered and custom produced 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.
		Quality Control
		All products are function tested after manufactured to guarantee zero defects. Our quality control department tracks all products and components by stamped-in serial numbers to trace any problem to assure zero re-occurrence. A certified quality management program assures a consistent level of quality.
		Warranty
		Each purchase is a one-time investment in superior quality; each product comes with a five year warranty, and is reliable even after a decade of use within its rated capacity.

JUNG vs. Look-Alikes

Why Choose JUNG? What Makes These Skates Unique? JUNG products have been copied many times. Those may look the same but certainly will not perform the same. Copies may drag over the surface instead of rolling. It may be close to impossible to change direction unless the cargo is lifted. It may damage the floor. It may be unmovable unless a towing vehicle drags the load rather than rolling it. The skate may fail terribly. It may need frequent repairing. The wheels need to be taken out and replaced very often. JUNG has obtained the technological know-how to develop, test, and manufacture machine skates in Germany during the last 50+ years, with one single goal in mind: To build a machine skate that truly works ... and works ... and works. Our skates will roll with ease, turn with ease, will leave floors intact, perform well under the toughest operating conditions, and have a long life span. They make the job much easier, much faster, and much more reliable for a very long time. As the original and finest skates in the industry, our products have been cloned into look-alikes. While the copied products may look the same - and can certainly move a load from place A to B - how easily and how reliably separates the good products from the bad. When compared with all the look-alikes, JUNG skates are the only ones designed, engineered, tested, certified, and permanently improved from the ground up - instead of being just imitated. They differentiate themselves from the look-alikes: By having a much higher breaking point Higher safety capacity (often times non-existing on look-alikes) Conforming to safety regulation (as compared to not conforming) Much better rolling and turning capabilities Better engineering employed under the hood Higher reliability and durability Longer life span Better quality parts and materials Making use of components constructed for the exact purpose Manufactured in an advanced production line Built by robots to guarantee consistent premium quality Incredibly high value as opposed to cost And with professional support and engineering assistance after the purchase JUNG products deliver excellence Made in Germany.

Manpower & Pulling Force Requirements

What is needed to move heavy loads with JUNG dollies & skates?

Our dollies and skates are outfitted with an advanced wheel material optimized for the lowest rolling resistance while protecting your floors. This rolling technology makes it as easy as possible to push and pull heavy loads. The innovation is derived from 50+ years of continuous testing and product improvement.

The table below is provided as a general guideline, for professionals only, as the strength per person varies and environmental and operational factors can greatly affect the rolling resistance. It should not be assumed that rolling and turning a multi-ton load is as easy as moving a piece of furniture. Moving heavy loads requires hard work and a lot of force and effort.

Load Weight	Up to 3 Tons	3-6 Tons	6-10 Tons	10+ Tons
Manpower Required	1 person	3 people	5 people or towing vehicle (recommended: Vehicle for safe braking)	towing vehicle

The manpower requirements to push & pull a load varies greatly and are influenced by several factors:

Floor conditions: It is easier to move a load on smooth and level concrete surfaces than on rough and uneven ground.
Weight per footprint: It is less difficult to move a load on a larger dolly/skate than on a small dolly/skate; as more wheels are available to support the weight, there is less weight for each individual wheel to carry. Since each wheel has less pressure placed on it, the load becomes easier to move.
Size of Wheels: Larger wheels roll easier than smaller-diameter wheels.
Time at Standstill: Rollers naturaly sag over time when at standstill. This increases the breakout resistance. So the time at rest will impact the force required to start rolling.
Temperature: High temperatures will cause the roller material to become softer which will increase the rolling resistance.
and more ...

Understanding Break-Out Resistance and Rolling Resistance

It is harder to get the load to start moving than to keep it moving. The force required to start the load moving from a standstill to a rolling state is called the Break Out Resistance.

This Break Out Resistance is approximately 5-10% of the Load Weight (worst case), depending on the factors mentioned above. This is also the drawbar pulling force required.

Once the load is rolling, it becomes easier to move. The Rolling Resistance is approximately 1/2 of the Break Out Resistance and requires only half of the force to keep the load moving.

Steering

A standard 3-point load moving system is the easiest to steer. The wheels are aligned in the direction of movement and the pulling handle acts like a lever to directly turn the steerable-front skate. Rotating dollies are slightly more difficult to steer as wheels can initially be pointing in different directions and must align to turn synchronously and simultaneously. Tandem machine skates and container dollies are more difficult to steer by hand because the turning force is transferred from the pulling handle into two parallel connecting bars which then turn the skates. In all cases turning while in motion is much easier than turning from a stand-still. And with all dollies and skates turning with a forklift is easy.

Safety First!

Please do not underestimate the Braking Force required to stop the load from moving. If you have ever pushed a stalled car, you know how difficult it is to stop a rolling vehicle. For loads over 5 tons we highly recommend using a forklift to be able to stop the load when necessary. If you operate any heavy load on a decline, ALWAYS use a forklift to avoid run-away loads.

Our dollies and skates are designed to reduce the manpower needed for moving heavy loads, equipment, and machinery. Our heavy load moving equipment is made by JUNG in Germany and offers a high quality commitment to the safety of your operators, machinery, equipment, and that of your very operation. Our wheel material is specially made for non floor damaging applications, as it will not mark or damage your floors. It's ideal for thin or delicate floors, from tile to epoxy surfaces. They make it easy to move the heavy load over rough and uneven surfaces.

You can move your heavy load with people, a forklift, or a puller. It will require one person for up to 3 tons, 3 people for 3 to 6 tons, and either 5 people or a forklift or puller for a load that weights 6 to 10 tons.
