Shackle ເປັນອຸປະກອນເສີມທີ່ເຂັ້ມງວດທີ່ຂາດບໍ່ໄດ້ໃນການຍົກການກໍ່ສ້າງ. Shackle ສາມາດຖືກນໍາໃຊ້ເພື່ອເຊື່ອມຕໍ່ pulleys ຍົກແລະ slings ຄົງທີ່. ມັນເປັນເຄື່ອງມືການເຊື່ອມຕໍ່ທີ່ມີຄວາມສະຫວ່າງແລະມີຄວາມຍືດຫຍຸ່ນທີ່ຖືກນໍາໃຊ້ຢ່າງກວ້າງຂວາງ.ສັ່ນສາມາດແບ່ງອອກເປັນສຽບໂບກແລະສຽບຮູບຕົວ U ຕາມລັກສະນະຮູບລັກສະນະຂອງມັນ. ອີງຕາມຈຸດປະສົງ, ມີ: ລະບົບຕ່ອງໂສ້, ລະບົບຕ່ອງໂສ້ທີ່ຍຶດໄວ້ໄດ້, ແລະເຄື່ອງມັດທີ່ເລື່ອນໄດ້.
(1) ຕ່ອງໂສ້ສຽບ is a ສຽບ used to connect the anchor chain. When in use, the horizontal bolt should be upward, and the horizontal bolt should be round to prevent it from rotating in the bolt hole and increase its strength. When using, first take out the horizontal bolt of the ສຽບ, put the U-shaped buckle into the anchor chain ring to be connected, and then connect the horizontal bolt in series to an anchor chain ring above. In order to prevent the horizontal bolt from coming out, there is an oblique hole at each of the two ends of the horizontal bolt and the U-shaped buckle for driving the brake oblique pin. In order to prevent the oblique pin from coming out, a green lead seal should be inserted into the cavity left at the pin hole. Before the oblique pin is inserted into the pin hole, calcium-based grease should be applied to prevent rust.
(2) ສະໍ ສຽບ is the ສຽບ used to connect the anchor chain and the sinker, and the method of use is the same as the chain ສຽບ.
(3) The floating ສຽບ is the ສຽບ used to connect the floating body and the anchor chain, and the method of use is the same as the chain ສຽບ.
