Shackle rated load: common market specifications for 0.33T, 0.5T, 0.75T, 1T, 1.5T, 2T, 3.25T, 4.75T, 6.5T, 8.5T, 9.5T, 12T, 13.5T, 17T, 25T , 35T, 55T, 85T, 120T, 150T. (Currently the world's largest shackle can reach more than 1000T, where Swedish GUNNEBO heavy shackle up to 1200T, U.S. CROSBY shackle up to 1500T.) The use of shackle shackle widely used in electric power, metallurgy, petroleum, machinery, railway, chemical industry, ports, mining, construction and other industries. Shackle material and use the current good shackle are generally used alloy steel, plain carbon steel changed in the past history. GB including general lifting shackle shackle, marine and general shackle shackle. Heavier, larger, generally not less frequently installed in the removal position. Select shackle should pay attention to the safety factor, there are generally four times, 6 times and 8 times. YOKE company produced a wide body steel shackle obtained DNV and ABS Type Approval, is China's ports, oil fields, marine industry of choice. Shackle use must be strictly complied with rated load, excessive use of frequent use and overloading are not allowed. Marine straight shackle arrest buttoned with unloading the whole body is made of high quality alloy steel forging and heat treatment is made of heavier, larger, usually installed in a position not often demolished. Shackle test load of 2 times the working load limit, breaking load is 4 times the working load limit. Main purpose and scope shackle rigging end fittings can be used in lifting operations connected directly with the hanging objects. Shackle can be used between the end fittings and rigging, only the connecting role. When used in conjunction with the beam rigging when rigging shackle can be used instead of the top of the lower part of the ear rings and beams board connector for easy installation and removal. Shackle lifting operation is the most widely used connectivity tools, lifting mainly used frequently mounting and dismounting joints.
