PRODUCT FOCUS The sonic tracer emits ultrasonic signals to maintain a set distance or elevation from an object, surface, or the ground. GRADING SOLUTIONS FROM BOBCAT Bobcat offers a wide range of grading solutions based around the company’s compact loaders and grader attachments. The expanded range of grading equipment is designed for use by asphalt and concrete contractors for excavating and grading work for new roads, pavements, concrete flatwork, tennis courts, utilities, and landscaping projects. Loader-mounted Bobcat grader attachments can now be combined not only with a comprehensive choice of Bobcat laser grading equipment, but also the Bobcat sonic tracer kit — the first sonic tracer system of its kind for compact loaders, to provide automatic grade control in applications where lasers may not be suitable. 22 APRIL 2019 Laser grading requires the job site to be on a plane, whereas the sonic tracer can follow nearly every terrain. The sonic tracer also provides an advantage when grading inside buildings with obstacles where the laser beam could be interrupted. The system offers the advantage that if the user already has a laser system mounted on the grader, they can also mount the sonic tracer on the blade, allowing them to switch between using the grader with the sonic tracer or the laser system. The Bobcat sonic tracer kit is designed for use with the 244mm and 274mm-wide heavy-duty grader attachments from Bobcat. Heavy-duty graders The 274mm-wide heavy-duty grader attachment is approved for use on the Bobcat S770 and S850 skid-steer, T770 and T870 compact tracked, and A770 all- wheel steer loader models. The 244mm- wide grader attachment covers the same models with the addition of the smaller T650 compact tracked loader. The graders feature a six-way blade plus hydraulic side-shift of up to 33cm left or right, both of which are fingertip www.plantonline.co.za
