Chain hoists Uses: chain hoists can be hung on the roof of a building or a crane beam use, but also with the monorail car, walk around to achieve the function of weight lifting. In addition to chain hoists can be used alone, can be used with all types of components supporting the use TROLLEYS Hand lifting and transport trolley, walk around to achieve the function of weight lifting, for overhead monorail transport, NRK single girder overhead cranes and cantilever crane. Chain hoist installation and removal are very easy, safe, fast and can be used for factories, miners, agriculture, electricity, construction of production and construction, cargo lifting, loading and unloading of vehicles, especially for missed days and no power supply chain hoists 8 Big Features: 1 Gear: Japanese technology; symmetrical arrangement of innovation speed synchronous gear; international standard gear steel double gourd abrasion resistance than ordinary, more stable rotation, hand pull lighter. 2 chain: higher strength chain; counterparts at the welding fine, medium frequency induction hardened after ISO3007-1984 meets the technical requirements of the international standard chain; adapt to sudden overweight job; hand zipper feel better; change ordinary hoist only to drop down vertically , from multi-directional, 45 ° angle pull, greater adaptation range. 3 hook: high strength material foot hook, advanced alloys, so that the fracture does not occur outside the bear overworked, but the gradual deformation, higher safety factor; hook at the new design, so that the goods will not be decoupled. 4 limit switches: limit switch hanging under the hanging parts, textile chain beyond to ensure safety. 5 parts: the main components are made of high quality steel, the implementation of strict size, weight checks to ensure the performance of each component of the full play. 6 Body: slim design, innovative and generous appearance; ergonomic, light body work activities of small interface, wide environment. 7 spray: advanced spray technology, both inside and outside hanging plastic, use another long table are brand new as ever. 8 Housing: pressed steel housing, solid in significantly lighter. Chain hoists usage rules: 1 Do not overload use. 2 Do not use power other than human action. 3 parts before use is required to confirm intact, transmission parts and lifting chain oiled, idling normal. 4 lifting hook before checking whether hanging down firmly. Do weights hanging at the tip of errors such operations. Lifting chain should be hung vertically, not a wrong twist of chain link, the next frame double hook chain not flip. 5 The operator should stand within the same plane pulled hands bracelet chain wheel, so bracelet wheel rotates clockwise, you can make the weight rise; reverse pull chain hands, then slowly drop the weight. 6 When lifting heavy objects, strictly prohibited under heavy loads to do any work or walking, in order to avoid personal injury. 7 in the lifting process, regardless of the weight up or down, drag chain hands, the force should be uniform gentle, do not use too much force, so as not to hand chain jumping or snap ring. 8 when the operator is found larger than normal hand pulling tension, you should immediately stop using it. Prevent the hand chain wear. Chain hoists maintenance methods: 1. Gourd should be cleaned after use and coated with anti-rust oil, stored in a dry place to prevent rust and corrosion from moisture chain hoists. 2 Maintenance and overhaul agencies who should be more familiar with the gourd, gourd with kerosene to clean parts, gear and bearing parts, plus grease lubrication, to prevent those who do not understand the principle of the free entry machine performance. 3 gourd after cleaning and maintenance, load test should be carried out to confirm working, reliable braking can be delivered. 4 brake friction surfaces must be kept clean. Brake parts should be regularly checked to prevent brake failure occurred since heavy fall phenomenon. 5. around sprocket chain hoists lifting roller bearings can be used in the butter has been pressed adhesion lifting sprocket mounted on the journal bearing inner ring, and then into the wall of the bearing outer ring. 6 chain hoists when installing brake parts, pay attention to the ratchet and pawl claw portion engages alveolar good control of the pawl spring should be flexible and reliable equipment to get started after sprocket wheel clockwise bracelet, it will ratchet , pressed the brake friction plate holder, bracelet wheel counterclockwise rotation between the ratchet and the friction plate should be no gaps. 7 In order to facilitate maintenance and removal, hand chain in which a series opening chain (no welded shut). 8 In the refueling process and the use of chain hoists, brake friction surfaces must be kept clean and regularly check the braking there to prevent brake failure caused by heavy since fall.
