Although the fundamental design and applications of motor graders have remained largely unchanged over the years, manufacturers the world over are continuously striving to enhance productivity, efficiency and operator comfort through advanced technology.
“Caterpillar always starts with the best in efficiency, effectiveness and power, and then makes its models even better with upgrades that enhance their most popular features,” explains Al-Bahar’s Ismail. “From the latest generation of advanced control joysticks to satellite-linked telematics, Caterpillar is constantly working to make the connection between operator and equipment more intuitive, responsive and flexible.”
“In addition to road construction, civil engineering and mining activities are driving demand for our motor graders,” says Ong. “Our most popular models are the Powerplus PP12GIX and PP14G-IX, which come equipped with 12-ft and 14-ft moldboards, respectively. Users who require more powerful machines tend to opt for the PP14G-IX Advance model, as it boasts a 220-hp engine and ZF transmission.”
“One innovation worthy of note is pilot joystick controls, which are located at either side of the operator’s seat,” Ong continues. “This technology is designed to replace the 10-lever control format, making operations more user-friendly. However, many still prefer the conventional lever system because, unlike with other heavy equipment, motor graders tend to be driven by specially skilled operators who have grown used to the conventional layout over many years. So, introducing more electronic functionality has its pros and cons; it really depends on user preference.”
While all manufacturers must offer a range of options to cater to varying customer requirements, Zhang notes that SDLG is continuing to invest in new innovations to ensure long-term success. “The G9220F is our most popular model in the Middle East, and the G9290 – our largest unit – is ideal for mining activities,” he says, adding that SDLG has improved its motor graders’ rear-axle functionality to enhance their performance while operating on slopes.
Shantui’s Du points out that, technology aside, any machinery deployed in the Middle East must be capable of handling even the most challenging of operating environments.
“The main concern of regional motor grader customers is quality; the machines must be able to endure high-pressure worksites, so durability, stability and efficiency are vital,” he notes. “At the same time, aftersales service, spare parts availability and ease of maintenance are equally important.”
