Suspended-arm labor-saving vacuum transport system is services for the production of, the design and selection of its shall comply with the need of the production process, but the creation of new material handling machinery often lead to the production process of change and improvement. For example, bucket wheel stack reclaimer, formed in Bucket Wheel Stacker Reclaimer as the heart, belt conveyor for blood vessels and electronic computer for central nervous automation of large bulk material handling system, thus changing the layout of ports, mines and the thermal power plant of the bulk field; forklift instead of bridge crane and transport operations in workshop, can simplify building structure and reduce construction cost.

In the latter half of the 20th century, the transport units obtained great development, the promotion of standardization of container and multimodal transport, water and land transportation loading and unloading work of simplified and cause the station, port layout and railway vehicle, ship structure change.

Material handling machinery can be the process of semi-finished products directly, automatically transferred to the next procedure, the many process into a system, the formation of a rhythmic production of; can also in the process of handling and the material for cleaning, drying, painting, sorting, storage, inspection and measurement, which can reduce the number of loading and unloading, shorten production cycle and save equipment investment.

In many production and operation process, material handling machinery is not a separate operation of the machinery, but the whole process is an integral part of the whole process. In studying and choosing the material handling machinery, we should not only know the material characteristics, handling of the objectives and requirements, and operations on the environment whether interference and pollution, must also be combined with the production or operation procedure to consider, closely linked to become a system to the mechanical handling and before and after all kinds of machinery, to reduce the loading and unloading areas and increase economic benefits.
