In the crane industry, working condition demonstrations are not only a showcase of product capability but also a declaration of technological confidence.
Since its launch, the HOISTON SUNHUNK H4680 has attracted continuous customer test drives. Each test features a full set of standardized lifting demonstrations, verifying performance under extreme conditions and responding to customer expectations with real load data.
HOISTON SUNHUNK H4680 steadily lifts a 131-ton weight block, demonstrating its outstanding load capacity for heavy equipment handling.
Equipped with a standard 20-ton counterweight, combined with a thickened luffing cylinder and reinforced structure, the H4680 ensures exceptional stability during lifting operations.
The H4680 shows its full-scenario adaptability across multiple dimensions:
15-ton lifting at full extended boom, 85-ton lifting at three-section boom pushing, and a maximum elevation angle of 80°, guaranteeing reliable long-distance lifting.
With a rational self-weight structure, it excels even in narrow spaces.
Even without relying on counterweight, the H4680 performs impressively:
96.5-ton rear lifting proves the rationality of its structural design;
85.4-ton side lifting reflects its full-direction operation capability.
The excellence of the HOISTON SUNHUNK H4680 lies not only in remarkable lifting performance but also in comprehensive upgrades to mechanism design, hydraulic systems and intelligent control.
With an optimized 13° departure angle, it operates smoothly and stably on slopes and easily navigates complex terrains.
As the second-largest special vehicle manufacturer in China, HOISTON SUNHUNK demonstrates its technological strength through every standardized customer test.
Each operation reflects strict requirements for design, manufacturing and commissioning.
Each set of data embodies a profound understanding of customer working conditions.
