In road construction, mining area maintenance, and municipal engineering projects, the CAT 140 grader has become a perennial favorite in global engineering projects due to its excellent leveling accuracy and long-term stability. However, in high-intensity, long-term operating environments, what truly supports the machine's stable operation is a crucial component hidden behind the tires—the wheel rim.
As one of the world's top three manufacturers of construction machinery and OTR rims, HYWG provides high-strength, highly compatible, and highly reliable rim solutions tailored to the working conditions of the CAT 140 grader, ensuring the equipment's continuous and efficient operation.
The core value of CAT 140 lies in "finishing , " and in road construction, CAT 140 determines the "final smoothness . " Precise smoothing places higher demands on the wheel rims .
During operation, the front wheels of the CAT 140 grader steer at high frequency and bear continuous lateral forces , while the rear wheels drive for a long time and bear the main traction and load . The long-term low -speed operation places extremely high demands on the fatigue performance of the wheel rims .
During operation, if the wheel rim deforms or the assembly is unstable, it will directly affect the leveling accuracy , driving stability , tire life and construction safety .
Therefore, CAT 140 requires professional-grade rims that are structurally reliable, dimensionally accurate, and stable over the long term.
HYWG 's 14.00-25/1.5 rims are custom-built to meet the performance requirements of the CAT 140 .
The 14.00-25/1.5 rim is a 3PC structure rim for TL tires, commonly used in graders. We are the original rim supplier of Liebherr.
Based on its deep understanding of construction machinery operating conditions, HYWG provides mature and reliable rims for the CAT 140 grader , using high-strength special steel produced in-house . HYWG possesses the capability to independently produce rim profiles , marking a watershed moment in high-end manufacturing capabilities within the OTR rim field. The advantage it brings goes far beyond simply "making its own materials"; it determines the rim's safety ceiling, consistency, and long-term reliability from the source. This provides the CAT 140 with stable load-bearing capacity, adapting to the machine's weight and the impacts of complex road conditions .
The 5PC multi-piece rim structure design is more suitable for heavy-load and frequent steering conditions. It is safe and efficient to install and maintain. The precise size and contour design can be highly matched with mainstream tire brands, ensuring even stress on the tread and reducing uneven wear .
HYWG 's "one-stop" production model , from steel rolling, mold design, high-precision forming, automated welding to surface treatment and finished product inspection , controls every step from raw materials to finished products , with strict quality testing to ensure that all products meet the same high standards and guarantee long-term continuous operation reliability .
