The Corghi EM9780C Plus represents the pinnacle of automated wheel balancing technology, engineered specifically for high-volume tire assistance centers, car dealers, and automotive manufacturers that demand precision, speed, and efficiency. Combining a full-color touchscreen interface with contactless dimension measurement and automatic wheel clamping via wireless WiNut technology, this advanced balancer eliminates manual operations and delivers unmatched accuracy for wheels ranging from 10" to 32" in diameter. With its fully automatic workflow, the EM9780C Plus achieves average measurement times of just 7 seconds on a 14kg wheel, making it one of the fastest balancers on the market. Capable of handling wheels up to 187 lbs. and with a max diameter of 44" (1118 mm) when equipped with the optional guard, this machine is built to tackle even the most demanding applications—from passenger vehicles to light trucks and specialty rims.
No manual operations required. The EM9780C Plus is designed to streamline your workflow by automating every step of the balancing process. From automatic wheel clamping with the revolutionary WiNut wireless system to contactless dimension detection and automatic positioning (RPA) at the end of each spin cycle, this balancer eliminates time-consuming manual tasks. Simply press the button on the sleeve to lock the wheel quicker and with less effort than ever before—no foot pedal required. The machine handles the rest, delivering reduced spin and diagnostic times that keep your bays moving and customers satisfied.
With three variable-speed cycle options (75-85-98 rpm) through the 3 Matic system, the EM9780C adapts to different wheel types and sizes, optimizing balance speed and accuracy. The 40 mm shaft diameter ensures robust support for heavy wheels, and the machine's 550W total power absorption delivers reliable performance shift after shift.
The intuitive touchscreen graphic interface on the EM9780C Plus simplifies operation and accelerates work program selection. Navigate through balancing modes, adjust settings, and access advanced features with a few taps—no complex button sequences or confusing menus. The modern interface provides clear, real-time feedback on wheel dimensions, imbalance values (up to 999g / 35.3 oz max), and counterweight placement, ensuring operators of all experience levels can achieve professional results quickly. USB ports allow for easy connection to peripheral devices and simplified software upgrades, keeping your equipment current with the latest Corghi innovations.
The One-Touch multi-function button further streamlines workflow by consolidating program selection into a single, ergonomic control. Combined with the machine's ability to support up to 3 users and customizable settings, the EM9780C Plus adapts to your shop's unique requirements and operator preferences.
The EM9780C Plus employs a sophisticated "combined" measurement system featuring an internal laser sensor and an external sonar sensor (Sonar AWD—optional). This contactless detection technology automatically measures wheel dimensions—rim width from 1.6" to 23.65" and rim diameter from 10" to 32"—without any operator intervention or physical contact with the wheel surface. Say goodbye to manual data entry errors and time-consuming measurements.
This advanced system dramatically simplifies the positioning of adhesive counterweights and ensures pinpoint accuracy on every job. The laser pointer indicates the exact position for applying adhesive weights with absolute precision, while the integrated LED illuminator floods the work area with bright, even light to facilitate rim cleaning and counterweight application—even in dimly lit service bays.
At the end of each spin cycle, the RPA (Automatic Positioning) feature brakes the wheel and automatically rotates it into the optimal balancing position. No manual searching, no guesswork—just instant, accurate positioning that accelerates counterweight placement and reduces operator fatigue.
The integrated LED illuminator bathes the rim in clear, shadow-free light, making it easy to clean the surface, inspect for damage, and apply weights with confidence. This thoughtful feature improves accuracy and speeds up every balancing operation, especially when working with dark-colored or complex spoke designs.
The new Hidden Weight Automatic program is a game-changer for high-end wheels and customer satisfaction. This innovative feature automatically divides the external side adhesive balancing weight into two equivalent weights concealed behind the wheel spokes, preserving the aesthetic appeal of premium alloy rims. The EM9780C Plus performs this complex calculation and positioning completely autonomously—no manual intervention required. Your customers get perfectly balanced wheels without visible counterweights detracting from their vehicle's appearance.
The Intelligent Positioning Lite feature is a specialized diagnostic tool that checks run-out and imbalance across all four wheels on a vehicle. Once the EM9780C Plus memorizes each wheel, it analyzes the data and suggests the optimal placement of each wheel on the vehicle to maximize ride comfort, minimize vibration, and enhance safety. When equipped with the optional Sonar run-out sensor, you gain access to even more comprehensive diagnostics, providing a complete picture of wheel condition and performance. This 4-wheel positioning capability is invaluable for tire assistance centers and dealerships focused on delivering exceptional service and long-term customer satisfaction.
Experience the future of wheel clamping with the WiNut wireless automatic clamping system. This revolutionary electromechanical design drastically cuts operating times and increases centering precision compared to traditional foot-pedal systems. Simply press the button on the sleeve to lock the wheel securely in place—quicker and with less physical effort than ever before. The wireless technology (operating at 2.4 GHz with a max RF signal power of 100mW) communicates seamlessly with the balancer, ensuring consistent, repeatable clamping force and perfect wheel centering every time. This innovation not only boosts productivity but also reduces operator fatigue during long shifts.
The UM Weight Management software suite includes the innovative LESS WEIGHT program, which reduces job times by 20% and cuts the quantity of counterweights used by 30%. This translates into real cost savings on consumables and a more environmentally friendly operation—an important consideration for shops committed to sustainability. By optimizing weight placement and minimizing material usage, the EM9780C Plus delivers professional balancing results while reducing your overhead and environmental footprint.
The OPT Flash (Imbalance Optimization) feature allows you to minimize road noise by adjusting the position of the tire on the rim. This advanced function optimizes the match between the tire and wheel, reducing vibration and enhancing ride quietness—a premium service that delights customers and sets your shop apart from the competition. It's an essential tool for high-end vehicle servicing and performance applications.
The slanted front panel on the EM9780C Plus ensures easier operator access to the inner section of the rim, reducing awkward bending and improving ergonomics during weight application and cleaning. The large integrated weight tray provides organized storage for different types of counterweights and tools, keeping your workspace tidy and efficient.
The compact PR Zero wheel guard (patented) is designed for space-efficient installation, including wall mounting options, while still accommodating wheels up to a maximum diameter of 44" (1118 mm). The machine's total footprint and 405 lbs. weight make it robust yet manageable for most shop layouts. The 110V / 1 PH power supply ensures compatibility with standard North American electrical systems, and the Easy Cal calibration feature simplifies setup and maintenance.
