Heavy-load scenarios: The "efficiency black hole" of ordinary excavators
In projects like mines and large infrastructure where single loading capacity exceeds 50 tons, ordinary excavators can only load 8 times per hour. However, the High Power Crawler Excavator, such as HW-520, with its 280KW high-power engine and 2×252cc large-displacement main pumps, can load 12 times per hour—an efficiency increase of 50%.
Let’s do the math:
With 10 hours of daily operation, ordinary excavators load 80 times, while the High Power Crawler Excavator loads 120 times;
For a project requiring 3,000 loads, ordinary excavators take 38 days, but the High Power Crawler Excavator only needs 25 days—shortening the construction period by 13 days directly!
Real case: The "30-day reversal" of a Canadian oil sands mine expansion
In an oil sands mine expansion project in Alberta, Canada, the contractor originally used ordinary excavators. Due to low efficiency in heavy-load operations, the construction period was severely delayed. After switching to the HW-520 High Power Crawler Excavato:
Loading times per hour increased from 8 to 12, completing 40 more loads daily;
The entire project, originally planned for 55 days, was finished in only 25 days—30 days ahead of schedule;
Savings in labor costs + equipment rental fees exceeded $250,000 (feedback from contractor Mr. Smith). The high efficiency of the High Power Crawler Excavator was fully demonstrated here.
Why choose the High Power Crawler Excavator?
lPower advantage
HW-520 is equipped with a Cummins QMS11 engine, with a rated power of 280KW and a torque of up to 1080N・m, easily handling 50-ton heavy loads;
The electronic control main pump + main valve system reduces pressure loss by 30% and fuel consumption by 15%.
lDurability upgrade
Mine-specific chassis design: fully protected track rollers, double-tooth plate crawlers, improving wear resistance by 50%;
Three-stage fuel filtration system, passing low-quality diesel durability tests, reducing failure rates by 80%. The durability of the High Power Crawler Excavator provides solid support for long-term operations.
Case testimony
"We used to lose $5,000 daily due to low equipment efficiency. After switching to the HW-520 High Power Crawler Excavator, we not only delivered ahead of schedule but also took on two additional orders!"—Project manager of the Canadian oil sands mine
