Hyundai Updates Excavators: Improved

Compact dimensions

Hyundai has updated its mid-weight compact excavators, with the introduction of the HX65A crawler model and the HW65A wheeled machine. The two excavators replace the popular R55-9A and R55W-9A, boasting a revised design, new technologies and upgraded features.

The operating weight has been increased to 6.0-6.5 tonnes, depending on specification, and both machines are now powered by Hyundai’s own Stage V diesel engine. This 2.4-litre motor delivers a maximum power rating of 48.5kW, with 248Nm of torque available and it drives a proven Bosch-Rexroth open centre hydraulic system, with Parker main control valves and an Eaton swing motor.

The hydraulic system is equipped with proportional joysticks as standard, with a ram lock switch mounted on the left-hand lever head. Double-acting breaker piping is also standard equipment and rotation piping is available as an option from the factory. The excavators feature an improved swing motor, offering increased operating speed and torque, boosting productivity in digging and loading operations.

The new cab design delivers improved space for the operator, with increased visibility and a fully adjustable and heatable operator seat. A revised air conditioning system provides optimised airflow within the cab and there are lower noise levels inside and externally. Bringing technology from larger Hyundai excavators, the compact machines now feature a 7” touchscreen monitor. This can be used to set auxiliary hydraulic flows for attachments.

Cabin working lights have been improved and there is now the option of full FOG (Falling Object Guard) guards at the front and top of the cabin, to provide additional protection on demolition and other hazardous operating sites. Rear and side view cameras provide improved visibility all around the machines.

In response to customer demand, the wheeled HW65A will be offered with a choice of single or twin tyres, available from the factory, to allow the machine to better adapt to a range of job site requirements, delivering optimal traction and stability.

Improved serviceability

Both the wheeled and tracked machines have wide opening engine hoods, providing easy access to regular maintenance items. All filters are placed within the engine compartment, with ground level access and a toolbox mounted within the cowl. A double-layer air cleaner delivers prolonged service life and Hyundai’s Hi-MATE telematic system is available to provide remote monitoring of machine working and performance.
