The Use Of American Shackles Jun 09, 2017

American shackle is a kind of rigging. Commonly used in the domestic market shackles, according to the production standards are generally divided into GB, American Standard, the Japanese standard three categories; which is the most commonly used American standard, US Type Shackle because of its small size and large load is widely used.

G20 (BW), G2130 (BX), G2150 (DX) by type can be divided into bow type (Omega-shaped) bow with a female shackle and D-type (U-shaped or straight Type) D-type with shackles; according to the use of places can be divided into two kinds of marine and land. Safety factor is 4 times, 5 times, 6 times, or even 8 times (such as Sweden GUNNEBO super shackle). Its material, common with carbon steel, alloy steel, stainless steel, high strength steel. Surface treatment is generally divided into galvanized (hot-dip and electroplating), painted, plated Dacromet (Dacormet). The load rating of the shackle shackle:

The common American shackles on the market are 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, which Sweden GUNNEBO heavy shackle up to 1200T, the United States CROSBY shackle up to 1500T. US Type Shackle Domestic can also be 1500T its technical content to the world's advanced level)

US shackle use: shackles are widely used in electricity, metallurgy, petroleum, machinery, railways, chemicals, ports, mines, construction and other industries. US Type Shackle The following are the same as the "

American shackle material and use: the current good shackles are generally made of alloy steel, changing the history of ordinary carbon steel in the past. Now Shanghai Shouhai ship equipment production of the US standard hot galvanized shackles maximum 6 times the safety factor is widely used by customers. GB shackles include general lifting shackles, marine shackles and general shackles. Heavier, bulky, generally not installed in the often disassembled position. Select the shackle should pay attention to safety factor, generally 4 times, 6 times and 8 times. YOKE company produced alloy steel wide body shackle, access to the DNV and ABS form certification, is our port, oil field, the ship industry's first choice. Shackle must be strictly used to comply with the rated load, US Type Shackle excessive use and overload are not allowed to use.

In the daily application of American shackle to do the following requirements

1, shackle should be smooth and smooth, not allowed to crack, sharp edge, burned and other defects. The following are the same as the "

2, is strictly prohibited to use cast iron or cast steel shackles. Button body can be used forging steel forging, shaft pin bar forging after machining. The following are the same as the "

3, should not be in the shackle on the drilling or welding repair. US Type Shackle The body and the pin are permanently deformed and can not be repaired. The following are the same as the "

4, when used, should check the button body and the pin, not serious wear, deformation and fatigue cracks. The following are the same as the "

5, when used, the horizontal spacing shall not be pulled, the pin must be plugged into a good insurance pin. The following are the same as the "

6, the correct pin assembly, the button body width shall not be significantly reduced, US Type Shackle good thread connection.
