Develon, formerly Doosan Construction Equipment, will be showing selected models from the company’s comprehensive range of equipment for use in quarrying and extraction operations, on Stand A9 at the STEINEXPO 2023 Exhibition from 23-26 August 2023.
The display at STEINEXPO will focus on crawler excavators, wheel loaders and articulated dump trucks (ADTs) from Develon. 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 will definitely be the highlight of the Develon STEINEXPO 2023 display, where the company will showcase the perfect interaction of its DX800LC-7 80-tonne (t) crawler excavator, DL550-7 wheel loader and, for the first time at the show, the new DA45-7 4×4 ADT.
The DX800LC-7 is the second largest crawler excavator in the current Develon range, alongside the new DX1000LC-7 100-t model. The operating weight of the DX800LC-7 is 79,5-t and it is powered by a Perkins 2506J six-cylinder engine with an output of 402 kW (547 HP). 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 will be 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 283 kW (385 HP) engine in the DL550-7 delivers optimal power while meeting Stage V environmental regulations.
The combination of these features gives this Develon wheel loader excellent balance, ensuring optimal bucket loading with every cycle of the loader’s 5,7 m³ bucket. The lifting arm with Z-kinematics provides excellent breakout forces and lifting capacities, especially for heavy materials.
The DA45-7 4×4 ADT is Develon’s first dump truck with 4×4 drive. The new 4×4 version of the DA45-7 ADT is intended to challenge rigid dump trucks in the 40-t class. With its 4×4 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 4×4 ADT also has a better turning radius than comparable rigid dump trucks.
The static display on the Develon Stand A9 will include 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 257 kW (349.5 HP) 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 240 kW (327 HP) at 1 800 rpm, 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 16,8 t (without tailgate) with a maximum payload of 28 t.
