Lifting Stroke: The "Core Benchmark" for Site Adaptability of Pile Driving Equipment
The lifting stroke of a static pile driver refers to the maximum vertical distance the equipment can lift during construction. It is a key indicator for the equipment to adapt to site flatness and achieve accurate alignment of pile bodies. The longer the stroke, the higher the equipment’s tolerance for uneven sites and the greater the flexibility in pile position alignment — this is crucial for projects with complex site conditions such as mountainous areas and urban village reconstruction.
According to industry research data, the lifting strokes of mainstream domestic static pile driver brands (such as Xintianhe) are generally in the range of 1.0-1.2m. However, multiple models of T-works series static pile drivers have achieved breakthroughs:
-The small-tonnage model ZYC 80 has a lifting stroke of 1.25m, exceeding the industry average by approximately 25%;
-The larger-tonnage flagship models ZYC 680 and ZYC 860 have a lifting stroke of 1.2m, leading similar equipment from peers by approximately 12.5%.
(I) Significantly Reduced Site Preparation Costs and Doubled Construction Efficiency
In traditional pile foundation construction, insufficient lifting stroke of equipment often requires substantial investment in site leveling. By using T-works ZYC 680 (with a lifting stroke of 1.20m), only minor adjustments to local height difference areas are needed.
"The large lifting stroke of T-works pile drivers has helped us break away from the traditional model of 'building roads first, then leveling the site' in mountainous photovoltaic pile foundation projects," a project manager of an energy infrastructure enterprise stated frankly. "The equipment can operate directly on sites with a 6° slope, and the pile verticality deviation is controlled within 0.25% — this was unimaginable in the past."
(II) Accurate Pile Position Alignment, Solidifying the Quality Foundation of Pile Foundations
Accurate pile position alignment is the core guarantee for the bearing capacity of pile foundations. The large lifting stroke of T-works series, combined with a 1.90m single pile driving stroke (standard configuration for all large-tonnage models in the series), enables "one-time alignment and precise driving."
Synergistic Technical Matrix, Forging an Industry Benchmark
The breakthrough in T-works’ lifting stroke is not an isolated innovation, but a microcosm of its overall technical system. Taking the ZYC 1260 as an example, in addition to a 1.35m lifting stroke, it also has core parameters such as 1260KN rated pile driving force and high-speed pile driving at 9.0m/min. It is compatible with large-diameter circular piles of φ1000mm, meeting the pile foundation needs of super high-rise buildings and river-crossing bridges.
Compared with peers, T-works has significant advantages in the "lifting stroke + pile driving performance + site adaptability" technical synergy:
"We have ensured the stability of the equipment and the linearity of pile driving force output while improving the lifting stroke by optimizing the synergistic design of the hydraulic system and walking structure," said the Chief Engineer of T-works Technology Research Institute.
