tiehöylät

Tiehöylät, often translated as road graders or motor graders, are essential heavy construction equipment used for creating a flat, smooth surface. They are characterized by their long, adjustable blade, positioned between the front and rear axles. This blade is the primary tool for their function, capable of scooping, spreading, and moving large quantities of material like soil, gravel, and sand.

The primary purpose of a tiehöylä is to level and shape the ground. This is crucial for various stages of construction, including preparing the sub-base for roads, building foundations, and landscaping. The blade can be angled, tilted, and raised or lowered to achieve precise contours and gradients. The operator controls these movements from a cabin, typically located above the engine and transmission.

Tiehöylät are powered by diesel engines and have multiple wheels, usually with four or six. Their weight and powerful engines allow them to move significant amounts of material efficiently. Modern tiehöylät often incorporate advanced features such as GPS guidance systems and laser leveling for even greater accuracy and reduced manual intervention. They are indispensable in road construction, infrastructure development, and large-scale earthmoving projects.
