Cut resistant innovative lightweight woven safety lanyards

目前，高空作业人员的安全是通过背带和绳索实现的。针对器官损伤的保护是通过减震机制来实现的；在绳索上缝合形成褶皱的材料，当受到脉冲力时，会导致缝合逐渐断裂，从而导致身体动量的衰减。新的立法要求绳索必须经受住苛刻的切割测试，以避免使用中出现故障的风险。目前的织造技术排除了使用较重、不灵活的纤维和织物的可能性，因为窄幅织物织机不够坚固，不能在不破坏织机提升机构的情况下织造所需的重量和类型的织物。目的是研究一种创新的经济改造的可行性，该改造将使用电子和嵌入式软件来控制伺服电机来执行起重操作，以生产出更轻且在功能上优于金属替代品的符合法律的绳索。

The safety of individuals working at height is currently achieved through a body harness and lanyard. Protection against organ damage is through a shock-absorbing mechanism; stitching in the lanyard to create pleats of material, which when subjected to an impulsive force causes the stitching to break progressively resulting in attenuation of body momentum. New legislation requires the lanyard to withstand harsh cutting tests to avoid the risk of failure in use. Current weaving technology precludes the use of heavier, inflexible fibres and fabrics as narrow-fabric looms are not robust enough to weave the weight and type of fabric required without destruction of the loom lifting mechanisms. The objective is to investigate the feasibility of an innovative economic retrofit which will use electronics and embedded software to control servo motors to perform the lifting operation to produce a lanyard which is lighter and functionally superior to metal alternatives in conforming to legislation.
