起重机和提升机具有更好的安全性和性能

工业起重机的安全与性能优化

在生产或运输过程中,设备和货物的吊装是所有重工业中的一项常见功能,由起重机完成。提高工作条件安全性和作业效率的驱动力意味着起重机对改善重工业的贡献越来越大。

一些最常见的工业起重机是桥式起重机和龙门起重机。在这些起重机中,负载通过缆绳悬挂在夹紧装置上,起到摆锤的作用。这些摇摆负载存在安全隐患,并对起重机结构施加额外应力。摇摆控制解决方案是使用n电机输入端的交流驱动。

杂交

使用柴油和电池储能的结合创造了机会,以减少高峰负荷,优化使用更便宜的非高峰电力,并在停电时维持运行。

  • 将消耗从电网转移到非高峰时段。通过在夜间非高峰电价下给电池充电,然后在工作日需求增加时使用存储的电量,起重机操作员可以使用时移来降低日常操作的电力成本。
  • 输入功率的峰值负载调整。通过使用电池存储的功率来提高峰值负载需求,例如,当起重作业开始时需要高扭矩时,电机可以免受峰值负载需求的影响。最终,这意味着起重机制造商可以将电机尺寸调整为常规负载,而不是峰值负载
  • 备用电源或断电启动。使用备用电池替换旋转备用电池,否则可能通过运行柴油发电机来实现。随着电池变得越来越便宜,在发生电源故障时,将电池集成到起重机中作为备用电池的可行性增加。
