HPE Africa’s new Hyundai HX series crawler excavators have been developed with a robust structure for high power, fuel efficient fast cycle speeds and precision control. Typical applications include construction, digging trenches, holes or foundations, road works, materials handling and laying pipes, as well as moving earth, demolition, or dredging.
“The value of the new HX series lies in its durability and high productivity. We are impressed with the robust and safe structural design of these machines, which enables efficient operation in tough African conditions,” says Ross Collard, MD, HPE Africa, part of the Capital Equipment Group (CEG) of Invicta Holdings Limited.
“These robust machines, which have been subjected to rigorous onsite testing, prove the reinforced durability of the upper and lower frame structure and attachments ensure dependable external shock and heavy work-loads. The wear resistance of the bucket has been improved through the use of new materials and vibration reduction of buckets enables more stable operation.
“Hyundai HX300SL and HX220S excavators are available locally from HPE Africa. HX300SL units, with Tier 2 / Stage V engines and an operating weight of 30 200 kg, have gross power ratings of up to 186 kW at 2 200 rpm. HX220S excavators have gross power ratings up to 110 kW at 2 000rpm, an operating weight of 21 260 kg and a 1,2㎥ bucket capacity.
“The three-stage power mode of these machines ensures the highest performance in any operating environment.”
The HX series is equipped with eco-friendly, high-performance engines that meet Tier 4 emission requirements. The new Eco Gauge level and colour displays indicate engine torque and fuel efficiency levels and advise of the status of fuel consumption. In addition, the average rates and hourly and daily based fuel consumption can be viewed in the detailed menu.
These new excavators have an advanced cooling system with a three-layer stacked-up module that improves air inflow and provides excellent cooling performance by increasing heat dissipation.
Through the Intelligent Power Controls (IPC) feature, the operator can easily select the correct mode on the monitor, to provide suitable power for each work environment. For example, on the excavation mode, pump flow is easily controlled by a lever, reducing fuel consumption.
The HX series also has an Attachment Flow Control (AFC) feature, designed to improve pump flow rate through the independent control of two pumps. This feature optimises attachments for the effective flow rate setting, depending on the attachment - there are 10 breaker types and 10 crusher types – to enable high performance in various operations, matching specific site environments.
Other enhanced features include the re-designed instrument panel, where electronic functions are concentrated to facilitate work efficiency and a full view front window and large rear and side windows provide excellent visibility in all directions. A state-of-the-art video camera system secures field of vision for operators in all directions, thereby preventing accidents onsite. An Intelligent Moving Object Detection (IMOD) system, with a recognition distance of 5 m, informs the operator when people or dangerous objects are detected within the range of operation.
A swing lock system improves operating speed and productivity and maintains stability when swing movement needs to be limited. A fine swing control option is also available when a fine swing is required.
The newly designed coil spring and damper inside the cab’s suspension mount reduce vibration and noise levels, improve durability and provide a comfortable space that lessens operator fatigue.
The HX series design allows for improved lubricity of connecting parts between the equipment and attachments. Wear-resistant long-life pins, bushes and polymer shims support high performance and durability. A wear-resistant cover plate is installed at the end of the arm to minimise abrasion on the connector between the arm and the bucket.
High-pressure hoses, with improved heat and pressure resistance and an enlarged air inlet with a fine net grill cover, prevents penetration of foreign materials, to ensure greater durability of the equipment.
Easy access to vital components gives an unrestricted view of components and allows easy maintenance and repair.
