The rationalization of loading and unloading 2021-06-20 14:44:37 The main goal of rationalization of loading and unloading is to save time, labor, and reduce loading and unloading costs. To this end, we can proceed from the following aspects: 1. Prevent invalid loading, unloading and handling Invalid loading and unloading, that is, unreasonable loading and unloading, should be avoided as much as possible, and various measures can be taken. For example, minimize the number of loading and unloading times and shorten the handling distance as much as possible to reduce the waste of manpower and material resources and the possibility of damage to the goods; enhance the lightness, simplicity, and practicality of packaging, avoid excessive packaging, and reduce ineffective loads; strive to improve The purity of the goods being loaded and unloaded, only the necessary goods are loaded, unloaded and transported. For some goods, impurities are removed before loading and unloading; the capabilities and loading space of the loading and unloading machinery are fully utilized. The hollow objects can be filled with other items before being transported. Improve loading efficiency; adopt a containerized method to carry out multimodal transportation, avoid repeated loading, unloading, and handling of a single piece of cargo, and so on. 2. Improve loading and unloading and handling activity. Loading and unloading and handling activity refers to the difficulty of changing the goods from a static state to a moving state of loading and unloading. Improving the loading and unloading and handling activity is an important part of the rationalization of loading and unloading. Depending on the state of the goods and the difficulty of loading, unloading and handling, the activity is also different. If it is easy to convert to the next step of loading, unloading and handling without too much preparatory work before loading, unloading and handling, the activity will be high; otherwise, the activity will be low. In order to distinguish the different degrees of activity, it can be expressed by 'activity index'. The 'activity index' is divided into five levels from 0 to 4, which respectively indicate the degree of activity from low to high. There are five basic transportable states of goods, namely, the bulk state, the integrated state, the integrated state, the loaded state and the moving state. Moving any batch of goods requires no more than four actions, namely, centralizing, sorting, lifting and moving. Each time the basic movement of handling is passed, the activity of the cargo's transportable state is increased by one level. In the table, the number of cancellations of the movement action is defined as the activity index (or activity), which is a quantitative description of the activity of the cargo. The greater the activity index of the cargo, the easier it is to load, unload and move. Therefore, improving the activity of loading and unloading is an important part of the rationalization of loading and unloading. When organizing loading, unloading and handling operations, various loading and unloading and handling machinery and equipment should be used flexibly, and the operation procedures should be rationally designed. For example, goods that are packed in containers and placed on the ground are easier to handle than goods that are scattered on the ground; when loading, they should be considered easy to unload, and when people are stored, they should be considered easy to leave the warehouse; it is also necessary to create an easy-to-handle environment and use Easy-to-consign packaging. In short, it is necessary to improve the activity of loading and unloading, so as to rationalize loading and unloading operations, save labor, reduce consumption, and improve efficiency.
