Aluminum alloy tightener light weight, easy to carry, lever force is small, yu diao company production of aluminum alloy lever hoist over traditional tightener, in the construction of tensioning wire, workers need to take pole tool, high altitude holding operations, light weight, convenient to carry, tight line tool lever force is small, can greatly reduce the workers of the operation difficulty, also can reduce the incidence of construction accidents, but traditional tightener material qualitative, design process, the conduction performance, the influence of such factors as hard to do the above three points, it virtually increased the construction worker's Labour intensity. The aluminum alloy hand lever calabash adopts the patent design to prevent the reverse ratchet, which greatly improves the safety performance of the operation. It is coupled with a one-time casting, with high strength and toughness, which greatly reduces accident rate. In addition, it is equipped with a hook, which can be used to hold the calabash on a fixed object to be more convenient to carry. Hebei yu diao lifting equipment technology co., LTD adhere to the professional technology, service, after sales services to timely and populist, patient want to customers think, do not do, normal product inventory quantities, can achieve 72 hours fast delivery, free provide engineering solutions
