In the colonial-era streets of Rio de Janeiro or the old urban road network of Buenos Aires, the upgrade of urban expressways in South America is facing a common problem: in a 5-meter-wide construction zone, large equipment can hardly move, and the selection of Construction Crawler Excavator for Agricultural Fields directly determines whether the project can break through spatial constraints. What is needed here is not a "bulky giant" but a 20-ton tool that can operate efficiently in narrow lanes – Hengwang HW220-9A Construction Crawler Excavator for Agricultural Fields, with its "small size", is rewriting the efficiency formula for old urban area renovation.
The pain points of road renovation in old South American urban areas are particularly prominent: large Construction Crawler Excavator for Agricultural Fields over 25 tons generally have a body width of over 3 meters. Entering a 5-meter-wide construction area requires disassembly and transportation, and the disassembly and assembly alone will extend the construction period by 2 months; while small excavators under 15 tons are so inefficient in breaking concrete pavements that construction teams are helpless. Hengwang HW220-9A (22-ton class, close to the 20-ton golden range) just fills this gap. Its total width is 2800mm, and the tail swing radius is 2925mm (≤4.5 meters), which can directly drive into narrow work zones without disassembly, perfectly adapting to the street scenes in Rio de Janeiro flanked by century-old buildings.
For more complex narrow passages, this Construction Crawler Excavator for Agricultural Fields is designed with detachable side plates, and the width can be further reduced to 2.8 meters, easily passing through even the stone-paved alleys in the old urban area of Buenos Aires. Equipped with the hydraulic breaker provided by Hengwang (a core configuration in the auxiliary tool list), the breaking efficiency is twice that of small excavators. When facing concrete bases, the single hammer impact can break a depth of 30cm – this is the key to its record of "completing 1 kilometer of base breaking in 3 days" in a certain expressway renovation in Rio de Janeiro. It should be noted that the traditional "small excavator + manual work" combination requires at least 7 days.
In terms of performance, HW220-9A Construction Crawler Excavator for Agricultural Fields is equipped with a Cummins 6BTAA5.9 engine, with a 133kw power output to ensure no "drop in performance" during heavy-load operations; the electronic controlled negative flow technology makes the hydraulic system more energy-efficient, reducing fuel consumption by 8% compared to similar models. High-strength structural parts have undergone three-dimensional finite element analysis, ensuring no deformation of the body during repeated breaking operations. The minimum ground clearance of 470mm can cope with potholed roads in old urban areas, and the 600mm-wide track plates enhance passability on muddy ground, allowing the Construction Crawler Excavator for Agricultural Fields to operate stably in the complex environment of South American rainy seasons.
Why can 20-ton Construction Crawler Excavator for Agricultural Fields become the first choice for narrow areas in South America? The answer from Hengwang engineers directly points to the core: "It balances three key points – width ≤3 meters to ensure entry, power ≥130kw to ensure efficiency, and swing radius ≤4.5 meters to avoid collisions." HW220-9A is the practice of this concept. Relying on Hengwang's "four-dimensional integrated" service system (product experience, user training, maintenance guarantee, accessory supply), it provides full from selection to after-sales, maximizing the efficiency of Construction Crawler Excavator for Agricultural Fields.
If you are troubled by the "spatial dilemma" of old urban area renovation in South America, you might as well focus on this 20-ton tool. Now enter "construction area width + construction period" to get a free "size adaptation map of 20-ton excavators in narrow spaces" (including recommended standards from local urban construction departments), so that each Construction Crawler Excavator for Agricultural Fields can accurately match the project needs.
