新的 P4HD.56R Rol 拖链是为最新的起重机开发的，具有非常高的速度和加速度。
New P4HD.56R Rol e-chain has been developed for the latest cranes, which feature very high speeds and rates of acceleration.
当今大型 STS 起重机中的拖链必须在更长的距离上更快地行驶，并且需要承载更重的填充重量。为了满足这些需求，igus GmbH 推出了一种新的重型产品。
Energy chains in today’s large STS cranes have to travel faster over longer distances and need to carry heavier fill weights. To meet the demands, igus GmbH has introduced a new heavy-duty product.
P4HD.56R Rol 拖链不会取代已建立的 P41.56R，后者仍可用于新项目，但将作为特别苛刻应用的替代品提供。
The P4HD.56R Rol e-chain does not replace the established P41.56R, which is still available for new projects, but will be offered as an alternative for particularly demanding appliCATions.
我们现在处于市场投放阶段，”igus 国际起重机部门负责人 Theo Diehl 说。我们已经在 3,800 平方米的测试实验室进行了广泛的测试。自 2021 年底以来，最终测试一直在一个行程为 150m 的户外测试台上进行。”
We are now at the market launch stage,” said Theo Diehl, head of igus’s International Cranes Unit. We have already run extensive tests at our 3,800 m2 test laboratory. The final tests have been running since the end of 2021 on an outdoor test stand with 150m of travel.”
Diehl 表示，P4HD.56R Rol 拖链是为最新的起重机开发的，具有非常高的速度和加速度。链条旨在完全应对这些参数，包括短负载周期的冲击负载——频繁的前后移动。
Diehl said that the P4HD.56R Rol e-chain has been developed for the latest cranes, which feature very high speeds and rates of acceleration. The chain is designed to cope fully with these parameters, including the shock loads of short load cycles – frequent short movements forwards and backwards.
根据广泛的测试结果，igus 表示，根据应用的不同，新型拖链的使用寿命长达 15 年，比 P41.56 系列提高了 50%。
based on the extensive testing results, igus says that, depending on the appliCATion, the new e-chain has a service life of up to 15 years, which is up to 50% more than the P41.56 series.
为此，它依赖于摩擦优化的高性能聚合物。为了进一步减少链条各点的磨损，引入了多项设计改进，包括三重止动系统和对称设计。
For this purpose, it relies on tribologically optimised high-performance polymers. In order to reduce abrasion at all points of the chain even further, several design refinements have been introduced, including a triple stopdog system and a symmetrical design.
与滑动链相比，集成滚子将所需的驱动能量降低了 57%。滚轮以交错的方式在彼此之上运行。梳状自动滑行横杆使链条保持在轨道上，提高了系统的安全性并减少了代价高昂的计划外停机时间。
The integrated rollers reduce the required drive energy by 57% compared with a gliding chain. The rollers run on top of each other in a staggered manner. The comb-like autoglide crossbars keep the chain in its track, increasing the safety of the system and reducing costly unplanned downtime.
在新的销/孔连接中，igus 使用其在聚合物滑动轴承技术中的专有技术，并依赖于经过验证的 iglident 材料，这也显着提高了链条的使用寿命。
In the new pin/bore connection, igus uses its know-how from polymer plain bearing technology and relies on a proven iglide material, which also significantly increases the service life of the chain.
