本公司供应耐用优质环链电动葫芦，品牌天桥，型号SSDHL250KG-5000KG。质量保证，欢迎咨询洽谈。 Our hoist ismade of high-strength alloy, consists of beautiful appearance, compactmechanism, small in size and light weight. And we use double-geared drive,helical gear drive when it works under fast speed, so that the hoists can drivesmoothly with low noise.本机采用高强度铝合金机体，外形美观：机体紧凑，体积小，重量轻，采用二级齿轮传动，高速级为斜齿轮传动。因而传动平稳，噪声小。Thecomponents and parts of our hoist is high-strength as well.零部件强度高Thehigh-strength alloy on the components and parts is going through multiplespecial technology for heating processing, so that it is high-strength and goodabrasion performance; the up and bottom hooks of our hoists are made ofhigh-strength alloy too, which is good in ductility cause of strengthen heatingprocessing, it means even the hoist is damaged by overload, the hook will onlybeen plastic distorted and never been brittle fractured.本机主要零部件均采用高合金钢材料，并且经过多道特殊热处理工艺加工，具有强度高，耐磨性好等特点：上下吊钩采用高强度合金钢制作：经强化热处理后具有很高韧性，即使机体因超载引起破坏：吊钩也只会塑性变形，而不会发性脆性断裂。
