Construction hoists by sprocket chain hoists, manual chain, transmission machinery, lifting chain and hook up and down several components. Which can be divided into mechanical transmission parts worm gear drive type and two kinds. Due to the low mechanical efficiency worm type transmission, parts easy to wear, so now generally used gear. Model specifications from 0.5 tons to 50 tons range. Hoists should be how to detect? A: Detection method: once a year. The first order of 1.25 times the rated load for 10 minutes static load test, then 1.1 times the rated load test hsz powered chain hoists preferred Xinyu, requires good braking performance, no stretch phenomenon; once a year after 1.1 times the rated Load dynamic load test. Chain hoists to be done before using it to check? A: 1, must identify their load capacity, not overloaded use; 2, check the hooks, chains, gears and brakes are good. Hook, sprockets, down card when deformed hsz chain hoists, and when the chain diameter amounted to 15% hsz wear wholesale chain hoists, is strictly prohibited. Also check whether the wrong link twisting, double under hook rack or without flipping chain, lifting chain link or without cracking. HS-VT chain hoists with a high-performance, high security and full of spirituality, talent, a separate faction, allowing you to more easily facilitate the completion of the work, you greatly reduce the labor intensity. Hoists Gear: symmetrical arrangement of innovative high-speed synchronous gear, the international standard gear steel, increased abrasion resistance than ordinary 2-fold more stable rotation hsz chain hoists, hand pull lighter. Chain hoists: chain counterparts at the welding of high strength fine, medium frequency induction hardened after. Hoists hook: high strength material foot hook, advanced alloys, higher safety factor, hook at the new design, so that the cargo is not easy decoupling. Hoists parts: the main components are made of high quality steel. Hoists Body: slim design, innovative ergonomic generous appearance. Hoists cover: stainless steel casing repression, strong in significantly lighter. hsz hoists specifications | Shanghai hsz hoists | Qingyuan Xinyu Xinyu lifting by Crane Co. provided.
