CONEXPO LIVE: Doosan
On the Doosan stand at this year’s CONEXPO-CON/AGG show, visitors are able to see the manufacturer’s new DL Hybrid wheel loader prototype for the first time, as well as the company’s new DX17Z-5 Electric Mini-Excavator, which also makes its debut. And how could we forget the 78-tonne DX800LC-5 crawler excavator (top picture) – the largest machine Doosan currently makes?
The DL Hybrid (see directly below) is a prototype hybrid iteration of the Doosan DL200-5 wheel loader, which combines an electric motor and diesel engine to provide the same amount of performance as a larger diesel-only engine. In addition to offering fuel savings from its hybrid design, this powertrain could be an option for customers working in sensitive areas where environmental concerns are greater than normal. According to Doosan, hybrid model configurations could be available in North America as early as 2023.
A year before then, Doosan’s new DX17Z-5 zero tail swing, electric mini excavator (bottom image) could be available for customers in the region. Instead of having a traditional diesel engine, the 1.7-tonne size class DX17Z-5 mini excavator is powered by a battery, located where the machine’s engine and fuel tank would normally be placed. The battery supplies power to an electric motor that is used to operate the mini excavator’s hydraulic system. Another machine making its North American debut in Las Vegas this week is the Doosan DX800LC-7 Crawler Excavator. Paired with a 4.7m3 bucket at CONEXPO, it is the biggest model in the company’s excavator line up and is scheduled to be available in North America in late 2020.
Other highlights from Doosan this year include its DA45 articulated dump truck and DL580-5 wheel loader. The new Stage V compliant DA45 ADT is being shown for the first time at CONEXPO-CON/AGG 2020. With a payload of 41 tonnes, the DA45 is powered by the new Scania Stage 5 compliant, 13-litre DC13 diesel engine with an output of 500hp. Doosan says the new Scania engine has undergone two years of intensive testing in construction and mining environments, and although the core of the engine has not changed, it features an improved after-treatment system. Meanwhile, with a bucket capacity of 5.4m3, the top-of-the-range DL580-5 wheel loader has a similar look to the next model in the range, the DL550-5, but features robust structural components and an advanced sophisticated double circuit axle oil cooler system.
