Chain hoists are lifting tools: a manual hoist it as an upgraded version of the fixed pulley device chain hoists, fully inherited the advantages of fixed pulley, while using a combination of reverse backstop brakes reducer and chain pulley block, symmetrical arrangement of two spur gears rotating structure, simple, durable and efficient. Qingyuan Xinyu Crane Co. hoist manufacturers supply chain hoists brand, size, model number, first introduce Shanghai Yan hoists. Shanghai Yan hoists its advanced design, reasonable manufacturing process, excellent performance, high-end domestic and international markets for the hoist, chain hoists Shanghai Yan has a beautiful appearance, small size, the use of safe, reliable, excellent strength machine; high transmission efficiency, hand light and feel good hand zippers, thus greatly reducing the operator's labor intensity and so on. Explosion-proof chain hoists using Rule 1, explosion-proof chain hoists lifting chain hoists supply should be hung vertically, not a wrong twist of chain link, double under hook rack chain not flip. The operator should stand on the same plane with the inner ring bracelet hands to pull the chain, making bracelets wheel rotates clockwise, you can make the weight increased; reverse drag chain hoists quality hands, noon to slowly decline. When lifting weights, strictly prohibited under heavy loads to do any work or walking, in order to avoid injury. 2, explosion-proof chain hoists in the lifting process, regardless of the weight up or down, hands pulled the chain, the force should be uniform and gentle, not too much force, so as not to beat or clasp the hand chain. When the operator is found hand-pull tension greater than normal, you should immediately stop using it. Maintenance method: after use should be cleaned and coated with anti-rust hoists hoists grease spot, stored in a dry place. Maintenance and repair should be compared with those who were familiar with the hoist mechanism to prevent the performance of the machine do not understand the principles of free disassembly. 3, explosion-proof chain hoists through cleaning and maintenance, load test should be carried out to confirm the work, reliable braking can be delivered. Brake friction surfaces must be kept clean. Brakes should be inspected regularly part to prevent brake failure, the occurrence of physical phenomena since the fall.
