Precautions for selecting loading, unloading, and handling tools

Change the productivity of science and technology, the development of science and technology make people more effort to do things, with the development of science and technology, the different transportation and handling tools, according to the production site environment appeared different handling tools, we in the workshop of warehousing logistics and choose a porter has time is different, this time, you know how to choose tools?

A) to meet the premise of field operations.

1 loading and unloading machinery should first meet the nature of the field operation and material characteristics, characteristics requirements;

If there is a railway line in the station, warehouse, etc., can choose portal crane; In the warehouse can choose bridge crane; In the production conditions of using pallets and containers, forklifts or even straddle cranes can be selected as far as possible.

2. The operation capacity (tonnage) of the machine and the amount of work on site should form the best coordination state.

The specific determination of the tonnage of loading and unloading machinery should be carefully calculated and analyzed according to the requirements of the site. On the premise of being able to complete the same operation efficiency, the loading and unloading machinery with good performance, energy saving, easy maintenance, favorable supporting and low cost should be selected.

3. Other influence conditions.

Throughput is the most basic factor that affects the amount of loading and unloading operations in logistics field. Besides, stacking, unloading and peak loading and unloading operations should also be considered.

The expenses incurred in the operation of loading and unloading machinery mainly include equipment investment, operating expenses and loading and unloading operation costs.

1. Equipment investment

Equipment investment is the average annual total investment in machinery and equipment (including purchase costs, installation costs and directly related ancillary equipment costs) and the corresponding machinery in one year to complete loading and unloading operations.

2. Operating expenses of loading and unloading machinery

The operating cost of loading and unloading machinery refers to the ratio of the total annual operating expenses of some machinery (including maintenance costs, labor wages, power consumption, lighting, etc.) and the amount of loading and unloading completed by the machinery.

3. Handling costs

Loading and unloading operation cost refers to the cost of loading and unloading a ton of goods by machinery at a logistics operation site, that is, the ratio of the sum of the average annual equipment investment expenditure and operating expenditure to the total tonnage of loading and unloading completed by loading and unloading machinery at the site each year.

Supporting equipment for loading, unloading and handling machinery

1. Supporting meaning of loading, unloading and handling machinery

The supporting equipment of loading, unloading and handling machinery refers to the reasonable selection of different types of related equipment according to the requirements of the field operation nature, transportation form, speed, transportation distance and so on.

2. Supporting methods of loading and unloading machinery

According to the amount of loading and unloading operations and the type of materials to be loaded and unloaded, based on determining the production capacity of all kinds of machinery, according to the number of machinery required to load and unload 10,000 tons of goods per year, the type of materials to be loaded and unloaded by each machine and the tonnage of goods to be loaded and unloaded each year.

In addition, the linear programming method can also be used to design the supporting scheme of loading and unloading operation machinery, that is, according to the requirements of loading and unloading operation site, a number of linear inequalities are listed, and the objective function is determined, and then the optimal number of various equipment.
