Applications

Municipal and Utility Engineering:
Municipal operations within cities are frequently constrained by confined spaces and surrounding environments. This model's compact body and agile slewing capabilities make it suitable for scenarios such as urban streets and residential areas. For instance, during the laying of underground utility lines for gas, water supply, and communications, it can precisely execute trenching, earthmoving, and backfilling operations. It can also participate in fundamental earthworks for urban road refurbishments and pavement renovations, alongside excavating and clearing municipal drainage channels, thereby ensuring the smooth progression of urban infrastructure development.

Landscaping and Forestry Operations:
When fitted with specialised attachments such as buckets and grapples, it can adapt to the diverse requirements of landscaping and forestry. In landscaping projects, it serves for site levelling and excavation of planting pits in parks and scenic areas, such as digging planting holes for tree transplantation and terraforming garden landscapes. Within forestry operations, it handles forest clearing, post-harvest site preparation, and foundational earthworks for supporting infrastructure, thereby aiding in landscape development and standardised forest management.

General Building and Site Formation:
The operational parameters of this model meet the core requirements of small to medium-sized construction projects. In small-scale residential developments and factory construction, it can undertake fundamental tasks such as foundation excavation, foundation pit levelling, and construction waste clearance. It is equally suited for site levelling in industrial and logistics parks, as well as pre-construction site clearance and obstacle removal. When fitted with attachments such as a breaker hammer, it can also handle the crushing of small rocks and concrete blocks during construction, thereby enhancing work efficiency.

Overseas customised adaptation scenarios:
As one of Hightop's flagship export models, its adaptability can be tailored to suit the working conditions of different countries through customisation. For instance, in Southeast Asian agricultural parks, it can be adapted for tasks such as excavating irrigation channels and preparing farmland sites. On certain infrastructure construction sites in Africa, it handles earthmoving operations during road construction and basic site levelling. For construction standards in parts of Europe and America, it can also participate in local small-scale municipal and building projects through customised environmental and safety configurations, adapting to local operational standards and environments.

Features

The power is mature and stable, and it is energy-saving and suitable for low temperatures:Equipped with a proven brand engine delivering a rated power output of 112 kilowatts, it provides smooth power delivery to support sustained medium-to-high intensity operations. Optimised power matching logic effectively reduces operational fuel consumption, while its outstanding cold-start performance makes it suitable for climates in regions such as Northern Europe, meeting the demands of diverse overseas working conditions.

Optimised operating parameters, robust multi-scenario adaptability:The machine's operating weight is 21 tonnes, featuring a standard 0.93 cubic metre bucket capacity. It achieves a maximum digging depth of 6,515 millimetres and a digging radius of 9,865 millimetres, offering extensive operational coverage. With a tail swing radius of just 2720 millimetres, it operates with agility in confined spaces. Supporting attachment changes such as breakers and grabs, it adapts to diverse tasks including earthmoving, demolition, and pipeline laying.

Sturdy and durable construction, built to withstand harsh environments:The core structural components are fabricated from high-strength steel, with a reinforced chassis design and critical welds subjected to enhanced treatment to withstand operational impact loads. The track features a well-balanced ground pressure ratio, minimising the risk of bogging on soft terrain. With a minimum ground clearance of 468 millimetres, it can handle minor road undulations and is well-suited for complex working conditions such as surface mining and outdoor hydraulic engineering.
