The Develon display at steinexpo was focused on crawler excavators, wheel loaders and articulated dump trucks (ADTs). The combination of these three machine types has been developed to offer customers from the quarry, mining 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.

Demo area was the highlight of the Develon display

The demonstration area was definitely the highlight of the Develon steinexpo 2023 display, where the company showcased the interaction of its DX800LC-7 80t crawler excavator, DL550-7 wheel 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 100t model. The operating weight of the DX800LC-7 is 79.5t and it is powered by a Perkins 2506J six cylinder engine with an output of 402kW. The DX800LC-7 is said to have the highest hydraulic flow for this size of machine, which Develon says has the best in class performance, with higher productivity, lower fuel consumption and smoother controls.

The DX800LC-7 was working in the demo area with the DL550-7 wheel loader, part of Develon’s award winning ‘DL-7’ family of wheel loaders. In the DL550-7, the powerful hydraulic system allows it to work quickly and efficiently. The Scania DC13 283kW engine in the DL550-7 delivers optimal power while meeting Stage V environmental regulations. The combination of these features has been designed to give this Develon wheel loader 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 40t 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 is also said to have a better turning radius than comparable rigid dump trucks.

In the static display

The static display on the Develon stand A9 included the company’s DX490LC-7 crawler excavator, the DL420CVT-7 wheel 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 1,800rpm, that 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 16.8t (without tailgate) with a maximum payload of 28t.
