Any bulldozer needs a proper blade for completing a specific type of job. The blade is probably the most important and most commonly used bulldozer attachment. In fact, the bulldozers originally come with blades. They use the blades for pushing different kinds of materials on the ground. Because the dozers are used for a variety of different construction and maintenance applications, a variety of dozer blades have been developed. Different soil characteristics, moisture level, temperatures, and compaction are just few of the many factors which determine what type of dozer blade will be used. Using a proper bulldozer attachment for specific job will result in higher productivity, fuel savings, better final results and less wear. The most commonly used dozer blades which can be found on the market are the following ones: S-blade, SU-blade, U-blade, angle blade, and PAT blade.
S-blade. The name of this bulldozer attachment suggests a straight geometrical S-shaped blade. This blade is attached to the dozer arms at the lower corner of the machine. It is vertically stabilized by angle braces that can be outfitted by a hydraulic tilt cylinder. The tilt cylinder increases the versatility, making the dozer capable of performing various operations on the ground. The S-blade has limited carrying capabilities because of the straight configuration. This bulldozer attachment is most commonly used for medium or hard materials. Typical applications for the S-blade include: stumping, backfilling, shaping, stripping, ditching etc.
SU-blade. The “SU” stands for semi-U blade. This bulldozer attachment is attached to the bulldozer with a heavy straight push arms. Like the S-blade, the SU-blade is also vertically stabilized by angle braces and hydraulically operated tilt cylinders. The thing that makes the SU-blade different from the S-blade, is the forward curving side wings which minimize the material spillage. This feature gives the SU-blade increased carrying and material loading capability. Although this bulldozer attachment provides less ground penetration than the S-blade, it has better material carrying capabilities making it a number one choice for a variety of tasks, like backfilling, stripping, leveling and crowning.
U-blade. Another popular and commonly used bulldozer attachment is the U-blade. The U-blade has great material handling and carrying capabilities, and it provides efficient soil movement. Again, the U-blade is vertically stabilized by angle braces. Tilt cylinders make the blade capable to concentrate ground penetrating forces for increased versatility on the job site. The increased width makes this blade an ideal bulldozer attachment for soft and medium soils.
Angle Blade. The angle blade is designed as a straight blade which is attached on the bulldozer frame. Attached in this way, the angle blade can be angled either to the left or to the right. The new bulldozers on the market come with angle blades which are designed with hydraulic tilts. This bulldozer attachment is most commonly used for applications like: ditching, shaping, stumping, striping etc.
PAT blade. The name “PAT” stands for power, angle and tilt. This blade is generally a straight blade which can be combined with different hydraulically operated bulldozer attachments. Because of that, the PAT blade is ideal for elevation and other similar ground tasks. This bulldozer attachment is described as a blade that significantly increases the productivity and the bulldozer versatility.
