In 2016, my country's annual cement output was 2.4 billion tons, ranking first in the global cement statistics, accounting for 60% of the world's output. The annual consumption is 1.851 billion tons. Cement is an important basic raw material for national economic construction. At present, there is no material that can replace it at home and abroad. As an important basic industry of the national economy, the cement industry has become one of the important symbols of the national economic and social development level and comprehensive strength. With the rapid development of my country's economy, cement plays an increasingly important role in the national economy.

At present, my country's cement production capacity has been completely overcapacitated. While continuing to strengthen macro-control, it is urgent to eliminate backward production methods, optimize the application of advanced technologies, extend the cement industry chain, and extend to the concrete industry has become the strategic transformation of the majority of cement enterprises. At the same time, the improvement of the original manual-operated bagged cement loading technology has been put on the agenda. Efficient, environmentally friendly, and safe intelligent unmanned loading systems are increasingly valued in the industry.

Loading bagged cement into trucks is a dirty and tiring heavy physical work. Foreign bagged cement trucks are loaded with special flatbed trucks for standardized shipment. There are many models of bagged cement transported in my country, ranging from heavy trucks to agricultural tricycles. Intelligent unmanned loading is extremely difficult. Among the existing mechanized loading equipment in China, they can be roughly divided into large-scale platform type, bucket lift forklift lifting type, and transmission belt conveying and manual placement type.
