　　Container spreader is a large-scale special machine tool for loading and unloading containers, suitable for cargo warehousing, water transport ports and terminals. As a special equipment, it has the advantages of reliable work, stable operation and relatively good efficiency. It plays an important auxiliary role in lifting the equipment. If a collision occurs during container loading and unloading, it often causes serious losses. How to avoid the box collapse is a problem that practitioners must always pay attention to. The main hidden dangers in the accident are the twisting mechanism of the wire rope and the spreader.

　　Similar spreaders are used for various container loading and unloading machinery. A set of strands are installed at each of the four corners of the spreader, and the hooks of each strand protrude downwards. When carrying the box, align the four twist lock hooks with the four rectangular lock holes of the container and place the spreader into the lock hole. After positioning, operate the oil cylinder to rotate the hook 90°, and the hook locks the lock hole. The container and spreader are integrated into a liftable locking state. The discharge operation requires lowering the spreader to a state without pulling hooks, and the operation hook rotates 90° in the opposite direction to unlock the lock. The spreader is lifted and separated from the container. The crank is connected by the rotating hook of the key and the spreader, and the oil cylinder pushes the crank, and the hook is able to rotate.

　　The relevant standards have high requirements for the safety performance of twist locks. The rotary lock of the container spreader adopts two types of safety methods: electrical interlocking and mechanical interlocking.

　　Mechanical interlocking can enable the twist lock to be opened when the spreader is in the box, but after lifting the spreader, the twist lock cannot be unlocked. When packing, press the box pin tightly and the spring is pressed upward, lift the upper stop ring of the box pin, leave the working plane where the rotary lock cam is located, and the rotary lock can rotate. After being lifted, the box-shaped pin extends downward under the action of a spring, and the limit retaining ring falls near the rotary lock cam. When the cam is stuck, the rotary lock cannot rotate.

　　Container spreader is detected by 3 switches. Switches with the same name as the four rotary locks of the spreader are connected in series in the control logic, and all ONs correspond to indicator lights.

　　The above is a brief introduction to the working principle of the boxing spreader twist lock, you can learn about it! If you have any questions or needs, you can contact us at any time, or you can leave your contact information directly, and we will contact you in time!
