In the district pipeline excavation site, its 6.41 meters of total length can turn flexibly in the 3-meter wide channel, wheeled design will not crush the asphalt road like the crawler, and it can drive back to the warehouse directly when closing down the work, which saves the towing fee. When building a house in the countryside, it can both dig the foundation and load building materials, 0.28 cubic meters of bucket with 1.2 tons of grab weight, demolition of old walls in the morning and leveling of the site in the afternoon, one machine is more than one machine. But if you go to the mines to dig hard rock, 7.2 tons of weight is too much, this kind of heavy-duty work also need to rely on a larger tonnage crawler, such as the same company's HWL150 crawler excavator is very suitable.
The HWL150 is a 15-ton crawler designed for heavy-duty applications. Equipped with a 110KW engine and a bucket capacity of 0.8 cubic meters, it nearly doubles the digging power of the HWL90, making it easy to cope with heavy work such as hard rock in mines and deep pit excavation for large-scale infrastructures. Moreover, the crawler chassis has strong grip, so it can work stably even on muddy mine roads and is not prone to breakdown even after 12 hours of continuous heavy-duty construction.
What's more, belonging to Hengwang, HWL150 can enjoy the same after-sales system as HWL90, which makes the supply of spare parts and technical support more convenient, and if a company purchases both models at the same time, it can also realize the sharing of resources between the maintenance team and reduce the management cost.
The cost of using HWL90 for a long period of time is also calculated. Running on the construction site for a year, its 12-15L/hour fuel consumption saves nearly 1,000 liters of fuel compared with a crawler, and according to the calculation of 250 working days, the fuel cost alone can save 10,000 yuan. Maintenance is also worry-free, 500 hours to change the oil and filter only cost 800 bucks, Japanese hydraulic parts to carry manufacturing, 7,000 to 8,000 hours without overhaul. What's more valuable is the freedom of transfer -- from the east of the city site to the west of the city, 35km/h speed than hiring a trailer to save half a day, ten trips a year to save 5,000 bucks. After three years, if you want to replace the equipment, the residual value of 50%-60%, together with the more than 100,000 dollars less than the imported machine at the beginning, saves 20% of the cost compared with the same class of crawler machine.
For small and medium-sized construction sites, HWL90 is like an “old friend who knows what he is doing”: it can drill on narrow roads and carry miscellaneous work, and the oil money and maintenance money are clearly calculated, so it doesn't hurt to use it for a long time. In the face of heavy-duty scenarios, the same company's large-tonnage crawler can take over the battlefield, so that different scales of projects have the right equipment to match.
