SHANTUI Motor Graders SG21-3
SHANTUI Motor Graders models include the SG16-3, SG18-3 and SG21-3. All are similar in characteristics, except for the graduated engine size and power ratings. The "3" stands for 3rd generation.
SHANTUI Motor graders features:
Radiators are produced by API Heat Transfer (Suzhou), with integrated water dispersers, air-coolers, transmission/torque converter oil coolers and hydraulic system oil converters combined into one, for effective heat transfer and a compact structure.
SHANTUI Motor graders Operational overview: Articulated steering greatly decreases turning radius, giving the grader more flexibility during operation. These graders can "crabwalk, " which allows the blade to extend beyond the rear wheel, thereby avoiding tires from treading on ground that has already been worked. Articulated steering also gives the grader self-correcting capabilities when it runs into problems.
The following accessories can increase the uses of graders: Rear rippers, moldboard, front/rear weights.
One major factor in the graders' optimum performance is proper selection of a blade rotational angle and blade angle. We recommend using a fairly large rotational angle, as this gives a relatively high digging pressure on every centimeter of length worked. During work with the blade, a small blade angle can decrease the cutting resistance, while a large blade angle can increase fineness of grading and the mixing effect.
The front wheel should be tilted towards the side of material flow. When working on inclined surfaces, place the front wheel in a vertical state, and with the help of the front wheel tilt, greater adhesion can be achieved.
While in operation, if there are no changes made to blades working height, manipulating the blade extraction device can stretch the blade forward.
These graders are not for work underground or in environments with poor ventilation. Due to the direct injection engine, the emissions special filter may not be sufficient.
