Types and Uses of Tractors as Construction Equipment

Reading time: 1 minute

A tractor is a versatile earth moving equipment that finds many uses at a construction site. While its primary purpose is to pull or push loads, it is also used as a mount for many types of accessories, such as front-end shovels, bulldozers and others. There are types and sizes to fit almost any job for which they are usable.

Crawler and Wheel Tractor

Types of Tractors

Tractors may be divided into two major types: Crawler Tractors and Wheel Tractors.

Crawler Tractor

Crawler tractors are usually rated by size or weight and power. The weight is important on many projects because the maximum tractive effort that a unit can provide is limited to the product of weight times the coefficient of traction for the unit and the particular road surface, regardless of the power supplied by the engine.

Wheel Tractor

Wheel tractors are either two-wheel or four-wheel. One of the primary advantages of a wheel tractor compared with a crawler tractor is the higher speed that may exceed (50 km/hr). However, in order to attain a higher speed, a wheel tractor must sacrifice pulling effort.
