Grader

Introduction

Motor grader is the main machinery used for shaping and leveling operations in earthworks, and is widely used in large-area ground leveling operations such as highways and airports. The motor grader has a wide range of auxiliary working capabilities due to its moldboard ability to complete 6 degrees of movement in space. They can be done individually or in combination. In the construction of the roadbed, the motor grader can provide sufficient strength and stability for the roadbed. Its main methods in subgrade construction are grading, slope brushing, and embankment. Motor grader is a kind of high-speed, efficient, high-precision and multi-purpose earthmoving machine. It can complete the ground leveling and trenching, scraping, bulldozing, snow removal, loosening, compaction, cloth, mixing, auxiliary loading and land reclamation in large areas such as important highway content fields and farmland. It is an important equipment in the construction of national defense engineering, mine construction, road construction, water conservancy construction and farmland improvement. Highway subgrade is the foundation of the pavement and an important part of highway engineering. The roadbed bears the traffic load from the pavement and is a supporting structure of the pavement, which must have sufficient strength, stability and durability. Depending on the terrain, highway subgrade generally adopts two forms: embankment and cutting.
