Easy to operate: earth-moving machinery

摘要

Earth-moving machines are used for excavating, loading, transporting, spreading, and compacting earth and other materials - see the examples of earth-moving machines on the following pages. They range in size from small machines that can drive through doorways to very large machines that can be worth several million USD. Operating an earth-moving machine is similar to driving a car or truck, except the operator must also control the machine attachment or work tool that moves the earth or other material. The operator stations on earth-moving machines are designed to comply with the ISO/TC 127/SC 2 safety and ergonomics standards to provide a working environment for the operator that is safe and comfortable, with controls that are easy to operate. By the 1960's the earth-moving machinery industry was already a global industry, with machines from the USA, Europe and Asia being sold into earth-moving applications around the world. Several countries were beginning to develop standards and regulations for earth-moving machines, which created a challenge for the industry to be able to meet the different requirements in different countries.
