HX430L Crawler Excavator

Hyundai Construction Equipment – Crawler Excavator HX430L

HX430 L Crawler Excavator

Introducing the  HX430 L Crawler Excavator. As part of the HX series, Hyundai promises innovative and powerful machine with high-quality performance and a strong drive. The HX430 L has maximised fuel efficiency and is overall a tough and sturdy work machine, prepared for any kind of working environment. To satisfy the needs of operators, the machine has been through a variety of tests at work sites to ensure the best quality machine.

Work Productivity and Efficiency

Compared to the 9 HX series, the HX430 L Crawler is proven to be up to 8% more fuel efficient in truck loading and levelling, a great benefit for operators and helping to reduce operating costs. The HX430 L is also up to 5% faster in levelling compared to the 9 series and has up to a 90% reduction in PM and NOX. Installed with a fuel-efficient system, the HX430 promises great performance as well as an eco-friendlier machine. For noise reduction in residential areas, the HX430 L provides an electronic viscous fan clutch, enabled to precisely control RPM depending on the coolant temperature and the hydraulic oil of the working machine. The fan clutch also helps to minimise fuel consumption whilst in operation, again, helping to reduce operating costs and providing a more environmentally friendly machine.

Machine Design and Features

The new HX430 L comes with a variety of new features for a more reliable and great performance machine. A new Fine Swing control is installed for a softer stop of the swing, as well as minimal shock loads. A Straight Travel Pedal has also been installed as an option for operators, this pedal aims to reduce operator fatigue as well as aiming to travel greater distances whilst working. Unlike previous models, operators can just hold down one pedal instead of two to easily travel around.
