AHSS increases the payload

The engineers at Weber-Stahl immediately got to work and developed the Muldy 3500, a trailer designed for professionals working in construction or horticulture that can easily carry up to two cubic meters of material. The main body and sides of the tipper are made of particularly durable, wear-resistant, high-strength steels (AHSS) such as ArcelorMittal's Amstrong Ultra 700MC material.

"The wear resistance of Amstrong Ultra 700MC enables customers to transport gravel, crushed stone or rubble with ease," says Alexander Schmitz. "Amstrong Ultra 700MC is a very interesting material because we can use it much thinner. This significantly increases the available payload of the tipper. For example, if we use Amstrong Ultra 700MC, the tipper weighs 800 kg. If we were to use a normal grade of raw material, it would weigh significantly more."

The advanced high-strength steel also withstands aggressive materials that are transported - such as sand and stones. "Tippers made of aluminum or with wooden side walls cannot withstand the wear and tear in the long term," explains Alexander Schmitz. "By using the AHSS types from ArcelorMittal, we have succeeded in developing a universal tipper that can cope with all types of material."

New models on offer

Two new models have been added to the Muldy range, as Alexander Schmitz explains: "In addition to the basic model, we now produce the Muldy 3500 Cargo and the Muldy 3500 Pick Up. Both tippers use Amstrong Ultra 700MC steel for the body and frame. The Cargo can take two pallets and even includes ramps so you can use a small forklift truck for loading."

The third option is the Muldy 3500 pick-up. "We have just started production of this tipper," says Alexander Schmitz. "The special thing about the pick-up is that you have a chassis and the option for multiple trailers. So one container can be filled while the other is being transported. It's perfect for daily, high-traffic use."

Weber-Stahl produces around 80 Muldy tippers every year. Demand is increasing due to their high quality and versatility. "Customers who bought a Muldy five years ago are still very satisfied with the machine. Whether in gardens, forests or on construction sites, customers can use their trailer in areas where other tippers cannot be used. And you don't need a special license."

Long relationship, good design

Weber-Stahl uses Amstrong sheets, which are produced at ArcelorMittal Bremen and supplied by its partner ESP. In addition to cutting the coils into sheets according to Weber-Stahl's specifications, ESP also smoothes the material.

The company first purchased products from Arcelor Mittal's AHSS range around 20 years ago. Alexander Schmitz explains: "We needed an alternative to S690 QL and discovered ArcelorMittal's Amstrong Ultra 700MC at a trade fair. We tested the material with our customer and found that it had much better cold bending capabilities and a higher strength-to-weight ratio. Arcelor Mittal also has good delivery dimensions. We can order material up to two meters wide, so we can cut more parts from one steel sheet."
