HD Construction Equipment has launched its first 40-ton DEVELON smart excavator, a next-generation model with significantly enhanced safety features and improved output and fuel efficiency.

HD Construction Equipment announced on January 23 that it recently held a DEVELON DX400 Unit 1 Delivery Ceremony at a large quarry in Sancheong County, Gyeongnam Province. The equipment will be deployed at concrete aggregate mining sites.

DX400 is equipped with the latest Hyundai DX08 engine, which increases maximum output and torque by 21% and 19%, respectively, compared to the existing model, featuring best-in-class performance. In particular, the application of the electronically controlled hydraulic system (FEH) delivers optimal pressure to the cylinders of each operating part, reducing energy loss and improving fuel efficiency by 22%.

It also supports the Human Detection System (HDS) function to prevent safety accidents. This function uses six high-resolution cameras and AI deep learning technology to identify people and objects within a 6-meter radius, including wide-area radar to detect blind spots and alert of collision risk.

The model also incorporates ergonomic design and digital technology to enhance driver convenience. A large touchscreen—1.5 times the size of the previous model—enables intuitive control of the equipment. Another addition is the digital key function, which allows remote starting and indoor temperature control via a smartphone app to reduce the hassle of preparing for work.

HD Construction Equipment has recorded global sales of approximately 100 units to date since launching the next-generation Hyundai DEVELON model lineup in Korea and Europe last year. The company plans to solidify its lineup of large-scale equipment further and expand its market base through a new launch in the US market in March this year and the domestic release of a new 30-ton product in the second half of the year.

The first DX400 customer cited superior power and fuel efficiency compared to the foreign equipment they had previously used as reasons for choosing the product, expressing satisfaction with the cutting-edge safety technology for accident prevention as well.

“Quarries are an extreme environment with continuous high-load work, and this delivery signifies recognition of the overwhelming performance of the next-generation new model. Starting with this, we will lead the generational change in the large excavator market,” an HD Construction Equipment representative said.
