本公司供應耐用優質環鏈電動葫蘆，品牌天橋，型號SSDHL250KG-5000KG。質量保證，歡迎咨詢洽談。 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.本機采用高強度鋁合金機體，外形美觀：機體緊湊，體積小，重量輕，采用二級齒輪傳動，高速級為斜齒輪傳動。因而傳動平穩，噪聲小。Thecomponents and parts of our hoist is high-strength as well.零部件強度高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.本機主要零部件均采用高合金鋼材料，并且經過多道特殊熱處理工藝加工，具有強度高，耐磨性好等特點：上下吊鉤采用高強度合金鋼制作：經強化熱處理后具有很高韌性，即使機體因超載引起破壞：吊鉤也只會塑性變形，而不會發性脆性斷裂。
