Electric Chain Hoist with Electric TrolleyModel:KD1Brand Name:TKKCounty Of Orgin:Hebei,Website: , China1.Made of high-strength alloy, consists of beautiful appearance, compact mechanism, small in size and light weight. Double-geared drive, helical gear drive when it works under fast speed, so that the hoists can drive smoothly with low noise.2.High-strength components and parts of hoist.3.The high-strength alloy on the components and pants are going through multiple special technology for heating processing, so that it is high-strength and good abrasion performance; the up and bottom hooks are made of high-strength alloy too, which is good in ductility cause of strengthen heating processing, it means even the hoist is damaged by overload, the hook will only have been plastic distorted and never been brittle fractured.
