Bulldozer blade is a heavy metal plate that's mounted to the front of the bulldozer. Mainly tasked with the pushing of material including rock, sand, soil, and refuse, it's shaped in a variety of configurations, each of which is suited to a specific range of tasks.
Within the bulldozer category, "standard" tends to mean different things when referring to blades, as each machine is engineered for productivity in a different way.Below are some different blades types.
This is the most common type of bulldozer blade. The straight blade, or S blade for short, is roughly shaped like a large rectangle. Used primarily for land clearing, finish grading, and pushing materials around a jobsite, an S blade is hydraulically controlled and can be tilted to dig - though digging depths are somewhat limited.
Designed with greater height than an S blade, the U blade has a slight curve to it (resembling a relaxed U) and also includes spill plates on either end to keep materials contained within the width of the blade during operation. This type of blade was created for longer runs, enabling the bulldozer to push materials across a field or entire jobsite. As such, they are ideal for moving rocks and gravel, boulders, and chunks of concrete. But they also provide the highly efficient transfer of dirt and other soil over extended distances.
A semi-U or SU blade combines the design and functionalities of the S and U blades, offering the best traits of both to provide a wider range of functionality. Though an SU blade is usually capable of less ground penetration than an S blade, it adds the spill plates on either side to contain the material within the width of the blade.SU blade is great for backfilling, ditching and crowning, leveling, and removing stumps.
An angle blade is a slightly more maneuverable version of the S blade. Featuring a rectangular shape, it's mounted on a C-frame to allow it to pivot left or right. Modern versions are hydraulically controlled and also include horizontal tilt for limited digging operations. As with a standard S blade, its shape allows spillage from either side, making it ineffective for pushing materials over long distances.Intended for general bulldozing applications including shaping, ditching, and removing stumps, it's ideal for clearing applications as well as road maintenance and construction
