Heavy construction equipment is available in Kingston. This refers to equipment that are specifically used in construction activities, such as dump trucks, graders, graders, scrapers, excavators, and so on. These are usually used for earthwork, and comprise five systems-implement, traction, structure, power train, control and information. These usually act as simple force multiplier machines. The transmission used is usually hydraulic. A number of different brands manufacture these equipment, for example Kubota, Caterpillar, Terex, Ingersoll Rand, John Deere and Navistar International Corporation. These equipment can be quite expensive, and often, one obtains used equipment for the project. Safety considerations have to be kept in mind during usage of such enormous equipment, as simple lapses can cause considerable injury and damage.
