Lifting block divided by the number of rounds, how many single door pulley, multi-door two-door pulley block war. Press pulley and hanging objects can be divided into hook-style adjoining block, chain pulley ring, rings, a rack-type pulley block war four. Mostly normal sized pulley hook type, chain ring battle rings Formula, () while large block using rings Formula war hanging beam. Divided by the contact wheel war between the axle shaft can be divided into two kinds of rolling bearings and plain bearings installed. Press plywood can be able to open points, there ashamed Du mouth pulley block war. Ashamed tackle plywood is able to open, easy to install rope pulley normally is a single door, it is often used in gin pole at the bottom of the foot as a guide pulley with. Tackle by use of style differences divided into fixed pulley block war movement. Block and tackle is inevitable fate of a given amount of truck () move the blocks and ropes constitute war Liaoning quality multi-car group skating, because when you're lifting weights, not only to change the direction of force, and also effort, such a single-use fixed pulley not grams less than the traveling block or handling problems. If the fixed and moving all the way to constitute a pulley block being linked group, both effort and can change the direction of force. If using multiple door fixed pulley block joint war movement is the way, the multi-door high-quality multi-block group Liaoning skating car group, to reach with a small force to lift heavy objects, just use. ~ T winch pulling out the tip sheave blocks, you can lift several tons or hundreds of tons of objects. Thus, the group is lifting tackle things in a wider use of lifting things. Use convenient, universal usefulness, it can be manually flexible. Mainly used for factories, mines. Agriculture, electricity, construction building production building of quays Liaoning quality multi-car group skating, shipyards, the stack of mechanical installation, lifting, etc. pulley lifting operation is the more an accessory manufacturers, and for the pulley type and material we How much better? The role of the pulley rope is used to change the direction of movement to achieve the purpose of saving or balanced. Whether by pulley axis movement points, fixed pulley and the movable pulley Liaoning quality multi-car group skating, lifting pulley fixed pulley mostly balanced and guide pulley. Divided by the manufacturing process, there is a pulley casting, forging and welding pulley sheaves made. Large pulley sheaves better welding, forging pulley rarely use, use of casting pulley hoist; steel pulley using ZG270-500; cast iron pulley using HT200; ductile iron pulley using QT400-18; Q235 steel welding pulley using solder.
