起重机制动下滑量检测仪是起重机型式试验、出厂试验、定期检验过程中必不可缺少的关键设备,对其安全性和试验精度及可操作性等要求很高。世界工程机械强国如德国、法国等对起重机制动下滑量都有相应的标准约束,并有相应的试验设备。我国多年来一直开展起重机制动下滑量检测,但由于检测手段落后,满足不了起重机的技术发展的要求,同时也制约了先进技术的应用。1制动下滑量的定义及检测要求起重机在制动后,负载由于自重将向下滑动一段距离,这个距离即制动下滑量。制动下滑量过大将直接影响到现场工作人员的安全,因此制动下滑量是衡量起重机性能的一个重要指标。虽然各生产厂家在起 Crane sliding volume detector is crane type test, the factory test, the essential inspection equipment during the regular key equipment, its safety and test accuracy and operability, and other demanding. World engineering machinery powers such as Germany and France have corresponding standard restraints on crane brake slip, and have corresponding test equipment. Over the years, China has been carrying out crane brake sliding quantity detection, but because of the backward detection means can not meet the crane’s technological development requirements, but also restricted the application of advanced technology. A definition of brake slip and detection requirements After the crane in the brake, the load due to its own weight will slide down a distance, this distance is the amount of brake slip. Braking slip too much will directly affect the safety of on-site staff, so braking slip is an important indicator of crane performance. Although the manufacturers are starting
