STEINEXPO provides an ideal meeting place for the national and international raw materials and building materials industry and was held again in Europe's largest basalt quarry, operated by Mitteldeutsche Hartstein-Industrie AG, in Homberg/Nieder-Ofleiden in the state of Hesse in Germany.

The Develon stand display at STEINEXPO focused on the company's crawler excavators, wheeled loaders and articulated dump trucks (ADTs). The combination of these three machine types offers customers from the quarry, mine and construction sectors complete solutions for excavation, loading and transport work, as well as meeting the needs of many application types, from general earthworks to the production of aggregates and building materials, all from a single source.

The Demonstration Area was the highlight of the Develon STEINEXPO 2023 display, where the company showcased the perfect interaction of its DX800LC-7 80-tonne crawler excavator, DL550-7 wheeled loader and, for the first time at the show, the new DA45-7 4x4 ADT.

The DX800LC-7 is the second largest crawler excavator in the current Develon range, alongside the new DX1000LC-7 100-tonne model. The operating weight of the DX800LC-7 is 79.5 tonne, and a Perkins 2506J six-cylinder engine with an output of 402kW powers it. The DX800LC-7 has the highest hydraulic flow for this size of machine, providing best-in-class performance with higher productivity, lower fuel consumption and smoother controls.

The DX800LC-7 worked in the Demo Area with the DL550-7 wheel loader, part of Develon's award-winning DL-7 family of wheeled loaders. In the DL550-7, the powerful hydraulic system allows it to work quickly and efficiently. The Scania DC13 283 kW (385 HP) engine in the DL550-7 delivers optimal power while meeting Stage V environmental regulations. Combining these features is said to give Develon wheeled loaders excellent balance, ensuring optimal bucket loading with every cycle of the loader's 5.7m³ bucket. The lifting arm with Z-kinematics provides excellent breakout forces and lifting capacities, especially for heavy materials.

The DA45-7 4x4 ADT is Develon's first dump truck with 4x4 drive. The new 4x4 version of the DA45-7 ADT is intended to challenge rigid dump trucks in the 40-tonne class. With its 4x4 design, the new version of the DA45-7 is better at handling bad roads, smoother driving surfaces and steeper terrain than rigid dump trucks. The DA45-7 4x4 ADT also has a better-turning radius than comparable rigid dump trucks.

The static display on the Develon stand included the company's DX490LC-7 crawler excavator, the DL420CVT-7 wheeled loader and a DA30-7 ADT.

The DX490LC-7 crawler excavator is powered by a Stage V-compliant Scania DC13 diesel engine, which provides 257kW of power. The increased power of the DC13 engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-Ecopower+) and the new generation Smart Power Control Technology (SPC3) to optimise productivity and fuel consumption, depending on the mode selected.

The DL420CVT-7 has a SCANIA DC9 engine with an output of 240kW at 1800 rpm, which complies with Stage V emissions standards. High-pressure fuel injection and precise timing ensure highly efficient fuel combustion and a perfect engine power stroke. The DA30-7 ADT has a maximum dump capacity of 16.8 tonnes (without tailgate) with a maximum payload of 28 tonnes.
