　　Container spreader has many types, including fixed and telescopic ones. Is there only one fixed one? Of course not. There are several types of fixed type. Let’s learn about some types of fixed type container spreader!

　　First let’s talk about the independent suspension device. According to the connection method with the crane, it can be divided into fixed connection and detachable connection.

　　1. Fixed connecting spreaders are generally suitable for lifting single-specification containers, and moving pulleys are generally installed directly on the spreaders. The locking mechanism of this type of spreader generally uses power drive, so the crane needs to be equipped with a control circuit with locking function. The spreader has a low lifting height, and the spreader uses multiple hanging points to connect, which can greatly reduce the shaking of the spreader. At the same time, the spreader does not need to rotate. Using the simple guide plate installed by the spreader itself can greatly improve work efficiency. Because the wire rope is directly wrapped around the pulley of the spreader, it will be more troublesome when replacing the spreader.

　　2. It can be divided into connecting spreaders. It is generally suitable for occasions where the container box type is complicated but does not lift frequently or when the container and other ordinary goods are required to lift at the same time. This type of sling manufacturer has connected the sling with the sling when it leaves the factory. When using it, users only need to hang the sling on the hook. The locking mechanism of this type of spreader generally uses a heavy hammer or ratchet, without additional power source, and is easy to install and use. Since the hook generally has no power to rotate, the spreader hanging on the hook also rotates. Therefore, when using such spreaders, someone needs to assist in the box. In the stacking yard, the stacking bins with more than 2 floors are not suitable for using such spreaders.

　　Then let’s talk about the master-slave spreader (maternal-child-type). The mother-child spreader consists of two spreaders, 20-foot and 40-foot spreader. The 20-foot spreader is a fixed-connected spreader for lifting 20-foot containers. When a 40-foot container is needed, the 40-foot spreader is used to lift 40-foot spreader, and then the 40-foot container is lifted with a 40-foot spreader. The twenty-foot spreader and the forty-foot spreader are respectively equipped with power sources for driving locking mechanisms. Because the size of the 40-foot spreader is relatively large, the weight of the 40-foot spreader is generally above 5t, so before using this spreader, the lifting weight of the crane must exceed 45t. This spreader has the advantages of relatively elasticity, low price, simple structure and convenient maintenance.

　　The above is an introduction to some types of fixed container cranes. You can learn that if you need it, remember to choose a manufacturer with stronger strength, more reputable and better after-sales service when choosing, which will save a lot of trouble in the later stage.
