铲运机拖拉机（履带） 3D模型

The scraper is a large piece of equipment used in mining, construction, agriculture and other earthmoving applications. The rear part has a vertically moveable hopper (also known as the bowl) with a sharp horizontal front edge. The hopper can be hydraulically lowered and raised. When the hopper is lowered, the front edge cuts into the soil or clay like a plane and fills the hopper. When the hopper is full (8 to 34 m3 or 10 to 44 cu yd heaped, depending on type) it is raised, and closed with a vertical blade (known as the apron). The scraper can transport its load to the fill area where the blade is raised, the back panel of the hopper, or the ejector, is hydraulically pushed forward and the load tumbles out. Then the empty scraper returns to the cut site and repeats the cycle. Highly optimized and detailed 3d model of "Scraper Tractor Tracked". Includes HDRI lightning map. Includes front light texture of 900 x 841 resolution in photoshop psd format. Real World Scale: Lenght: 660 cm Width: 408 cm Height: 394 cm
