The Corghi EM9780 Plus represents the pinnacle of wheel balancing technology for high-volume tire centers, car dealers, and automotive manufacturers. Combining touchscreen interface technology with contactless dimension detection, this fully automatic wheel balancer delivers unprecedented speed and precision without requiring the operator to manually measure or touch the wheel during setup. Engineered for professionals who demand both efficiency and accuracy, the EM9780 features advanced capabilities including automatic positioning, LED work illumination, laser-guided weight placement, and intelligent diagnostic tools that streamline every aspect of the wheel balancing process.
Built to handle wheels up to 44 inches in diameter with a maximum weight capacity of 187 lbs, this professional-grade balancer accommodates rim diameters from 2" to 32" and widths from 1.6" to 23.65". With variable speed cycles, multi-user support, and innovative features like Hidden Weight Automatic and OPT Flash optimization, the EM9780 transforms the wheel balancing workflow while reducing counterweight usage by up to 30% and cutting job times by 20%.
Touchscreen Technology: The advanced graphic interface and touchscreen control system simplify and accelerate every operation. Work program selection becomes intuitive and immediate, eliminating the learning curve typically associated with professional wheel balancers. Operators can quickly access all functions and settings through the responsive touch interface, significantly improving workflow efficiency in busy shop environments.
Contactless Dimension Measurement: The EM9780 employs a sophisticated "combined" measurement system featuring an internal laser sensor paired with an optional external sonar sensor (Sonar AWD). This contactless technology automatically measures wheel dimensions without any intervention from the operator. The wheel balancer captures all necessary measurements—diameter, width, and offset—completely hands-free. All operations for positioning adhesive counterweights have been streamlined through this intelligent measurement system, eliminating manual entry and potential human error.
RPA Automatic Positioning: At the end of each spin cycle, the wheel is precisely braked and automatically rotated into the exact balancing position through the RPA (Automatic Positioning) system. This eliminates manual wheel rotation and ensures the counterweight location is immediately ready for weight application. The system calculates the optimal stopping point and delivers it with repeatable accuracy, spin after spin.
Integrated LED Illuminator: The built-in LED work light system illuminates the entire work area precisely where you need it. This focused illumination facilitates thorough rim cleaning and makes counterweight application faster and more accurate. Working conditions are optimized regardless of ambient shop lighting, reducing eye strain and improving the quality of every balance.
Laser Point Precision: The internal laser pointer system indicates the exact position for applying adhesive counterweights with absolute precision. A bright laser dot shows you precisely where to place each weight, eliminating guesswork and ensuring perfect balance every time. This adhesive counterweight application system dramatically reduces placement errors and accelerates the finishing process.
Hidden Weight Automatic: The innovative "Hidden Weight" program represents a breakthrough in cosmetic wheel balancing. This automated function divides the external side balancing adhesive weight into two equivalent weights that are concealed behind the wheel spokes. The EM9780 calculates the split automatically and positions each weight location—a completely autonomous operation that preserves wheel aesthetics while maintaining perfect balance. This feature is especially valuable for high-end alloy wheels where visible weights detract from appearance.
Intelligent Positioning Lite (4-Wheel Positioning): This specialized diagnostic tool checks run-out and imbalance across an entire vehicle's tire set. Once all four wheels are measured and memorized, the EM9780 Plus analyzes the data and suggests the optimal placement of each wheel on the vehicle for maximum comfort and safety. When equipped with the optional sonar run-out sensor, the system provides complete diagnosis including radial and lateral run-out measurements, enabling you to identify problematic wheels and optimize tire-to-vehicle matching for the smoothest possible ride.
UM Weight Management Software: The Weight Management suite includes the powerful LESS WEIGHT program, which intelligently optimizes counterweight placement to reduce both the quantity of weights used and the time required for balancing. Real-world results show job time reductions of up to 20% and counterweight usage reductions of up to 30%, delivering more cost-effective and environmentally friendly operation. Less weight on the wheel also means reduced stress on wheel bearings and suspension components over the vehicle's lifetime.
OPT Flash - Imbalance Optimization: The OPT Flash feature minimizes road noise by allowing the operator to alter the position of the tire on the rim to optimize overall quietness. By analyzing the relationship between tire uniformity and wheel geometry, this program identifies the optimal tire-to-rim clocking position, reducing vibration harmonics and improving ride quality. This advanced capability sets the EM9780 apart in shops focused on delivering premium service.
One-Touch Multi-Function Button: The One-Touch button makes work program selection simpler and faster than ever. This ergonomically positioned control consolidates common operations into a single, convenient interface point, reducing the number of steps required to initiate balancing cycles and switch between functions. Operators spend less time navigating menus and more time completing wheels.
Ergonomic Weight Tray: The weight holder top features large, organized trays designed for different types of counterweights and tools. Everything you need is within arm's reach and neatly organized, reducing motion waste and keeping the work area clean. The functional layout accommodates both clip-on and adhesive weight inventories with room for rim cleaning tools and other accessories.
Slanted Front Panel & Compact Wheel Guard: The slanted front panel design provides easier operator access to the inner section of the rim, making it simpler to clean the bead seat area and apply inner adhesive weights. The PR Zero compact wheel guard (patented design) is engineered for space-conscious shops and even accommodates wall mounting while still handling wheels up to a maximum diameter of 44 inches (1,118 mm). This space-efficient guard design doesn't compromise safety or capacity—it simply maximizes your shop's usable floor space.
3 Matic Variable Speed Cycle: The EM9780 offers three balancing speed options (75, 85, and 98 RPM) to accommodate different wheel types, weights, and operator preferences. Variable speed capability allows you to optimize cycle time versus measurement precision based on the specific wheel being balanced. Lighter wheels can be spun at higher speeds for faster results, while heavier or larger wheels benefit from lower speeds that reduce vibration and improve accuracy.
Multi-User Support: The balancer supports up to 3 individual user profiles, allowing multiple technicians to save their preferred settings, calibration data, and work preferences. Each operator can log in to their personalized configuration, ensuring consistency and reducing setup time when technicians change shifts or share equipment.
Easy Cal Calibration System: The Easy Cal feature simplifies the calibration process, ensuring the balancer maintains peak accuracy over time. Guided calibration routines walk operators through each step, and the system verifies calibration quality automatically. Regular calibration is faster and more foolproof, helping maintain the precision that professional wheel balancing demands.
Shift Plane Function: The Shift Plane capability allows operators to mathematically shift the balancing plane position when wheel geometry or mounting conditions require it. This advanced feature provides flexibility for unusual wheel configurations and helps achieve optimal balance in non-standard situations.
USB Connectivity: USB ports enable connection to peripheral devices and provide a simplified pathway for software upgrades. Firmware updates can be loaded via USB drive without requiring network connectivity or specialized tools. This connectivity also opens possibilities for data export, reporting, and integration with shop management systems.
The EM9780 features manual wheel clamping as standard, using a reliable 40mm shaft diameter and traditional cone/spring configuration. This proven clamping method provides secure wheel mounting and is compatible with the full range of standard balancer cones and adapters. The wheel/machine support flange distance is 10.82 inches (275mm), accommodating a wide variety of wheel backspacing configurations.
For shops seeking the ultimate in convenience, the new WiNut Automatic Clamping System is available as an optional upgrade. This innovative wireless technology system (operating at 2.4 GHz frequency with 100mW maximum RF power) allows for power-assisted wheel clamping and unclamping, reducing operator fatigue and further accelerating the wheel mounting process. The WiNut system represents the cutting edge of balancer clamping technology.
