Description

Technical Field

[0001] The utility model belongs to the technical field of AGV equipment, and in particular relates to an AGV tractor. Background Art

[0002] In recent years, with the rapid development of the logistics and warehousing industry, traditional manual operations have some very obvious shortcomings in the logistics and warehousing industry. Common shortcomings include (1) low efficiency: traditional manual operations require a large amount of manpower input, but human resources are limited and cannot quickly meet the needs of high-intensity, large-scale operations, and manual operations have low efficiency; (2) high error rate: manual operations are easily affected by factors such as fatigue and human negligence, resulting in errors; (3) high cost: employing a large number of people will increase the company's human costs, including wages, training and other expenses. In addition, it is necessary to consider employee welfare, labor protection and other issues, which further increases the burden on the company; (4) high labor intensity: traditional manual operations usually require repetitive and tedious physical labor, which can easily lead to worker fatigue and injury. In the long run, it is easy to lead to employee turnover and increased recruitment difficulties, which also indirectly increases the burden on the company.

[0003] Based on the problems existing in traditional manual operations, there is an urgent need to design an automated equipment that can replace traditional manual operations, improve operation efficiency, reduce error rates, reduce labor costs, and reduce labor intensity, which will help improve the overall competitiveness and development level of the logistics and warehousing industry.
