Corghi, a world-leading manufacturer of tire changers with decades of expertise, has redefined what's possible for professionals in the heavy-duty tire industry. The Monster AGTT represents a revolutionary leap forward, engineered specifically for tire specialists working on trucks, buses, farming equipment, earth-moving machinery, and fleet transport vehicles. Integrating cutting-edge patented technologies with unmatched versatility, the Monster AGTT delivers fully automated tire changing, maximum rim and tire protection, and operator safety that fundamentally transforms the heavy-duty tire service experience.
This is not just an incremental improvement—it's a complete reimagining of the tire changing process. With the Monster AGTT, technicians gain access to an efficient, rapid, and top-quality service solution that significantly reduces physical strain, eliminates risk, and protects both the wheel assembly and the operator. Whether you're servicing 14" to 48" wheels with tilt capacity up to 58", handling wheels up to 98.4" in diameter, or working with tire assemblies weighing up to 3,747 lbs, the Monster AGTT is the irreplaceable tool that redefines working quality and productivity for industrial tire operations.
The Monster AGTT is the only super-automatic tire changer in the world equipped with the exclusive "Leva la Leva" technology—a patented system that dramatically reduces physical strain and risk for specialized professionals changing all types of heavy-duty tires. This revolutionary approach to tire service means technicians can work faster, safer, and with far less fatigue than ever before.
Equipped with an automatic and self-centering wheel clamping device that requires no extensions, the Monster AGTT offers an advanced electronic system to save rim diameters and wheel positions. The innovative "Side To Side" (S.T.S.) device enables the tool block to move automatically from one side of the tire to the other, eliminating manual repositioning and streamlining the entire workflow. This intelligent automation transforms a physically demanding task into a smooth, controlled, and repeatable process.
The entire tool block on the Monster AGTT is operated hydraulically, delivering precise, controlled movements that safeguard expensive rims and tires. The heart of this protection is the "Leva la Leva" device, which performs tire changing in a completely automated manner. A special hydraulic bead loosening disc reaches the perfect inclination in each phase of the process, adapting dynamically to the tire geometry.
A fundamental feature of the system is the tool arm's coordinated movement with the turntable, which maintains tool-rim tangency at all times. This means the wheel and tools remain perfectly aligned in all situations, reducing tension, avoiding unwanted contact, and consequently totally safeguarding the integrity of both rims and tires. The result is damage-free service, protecting your investment and your customers' wheels.
With a maximum internal axial bead loosening force of 6,750 lb(f) and external force of 5,625 lb(f), the Monster AGTT delivers the power needed for the toughest jobs—while the hydraulic precision ensures this power is applied safely and accurately.
The Monster AGTT is designed and manufactured to guarantee maximum versatility and efficiency for the operator. The single position of the tool block on the carriage makes tire changing jobs easier and quicker. New play recovery pads eliminate play due to wear over time, ensuring consistent performance throughout the machine's lifespan.
The memory function saves the position of the tools, speeding up positioning during tire changing operations and reducing setup time between jobs. Synchronized movement between the tool chuck and carriage, combined with the electro-hydraulic control unit with display, gives operators unprecedented control and customization. The system can be adjusted to match the specific requirements of each tire being serviced, and the ability to automatically position the finger and disc tangent with the rim makes the Monster AGTT truly one of a kind.
The hydraulic chuck features a drive inverter motor with three rotation speeds (1, 3.5, and 7.8 RPM) and an impressive maximum rotation torque of 4,059 ft/lbs. This power and flexibility enable efficient handling of any tire type, including tire groove forming. The 4-tilted-jaw locking unit (patented) delivers a maximum locking force of 9,000 lb(f), ensuring wheels remain securely clamped throughout the service process.
The Monster AGTT is designed not only to reduce strain but also to guarantee maximum operator integrity and safety. The innovative design eliminates the need for a raised base, which consequently eliminates dangerous unbalanced situations when loading large and heavy wheels. This solution allows the operator to work in complete safety with the wheel raised off the ground by just a few centimeters—a floor-level wheel loading area that dramatically reduces lifting risk and physical strain.
The new mobile controller with ergonomic, handheld controls allows the operator to command all movements without touching the tool block. This independent wheel-mounted control unit (trolley style) makes the technician's job much easier and safer, enabling full control from a safe distance. An emergency button is integrated for immediate stop capability, and the entire system operates at a quiet 63 dB(A) noise level, creating a safer and more comfortable work environment.
The universality of the Monster AGTT is guaranteed by the new self-centering locking turntable made up of tilting jaws with 9 direct lockable positions, from 14" to 48" and with tilt capacity up to 58". The system is pre-arranged to lock rims with a minimum center hole diameter of 90 mm (3.5"), providing incredible flexibility across vehicle types.
The turntable is equipped with a drive inverter that automatically delivers the optimal rotation speed for each job, including specialized tasks like tire groove forming. With a maximum tire diameter capacity of 98.4", a maximum wheel weight capacity of 3,747.8 lbs, and a minimum working height to chuck shaft of just 17.7", the Monster AGTT handles virtually any heavy-duty wheel assembly with ease.
The new and exclusive tilting jaw adapts perfectly to all types of rims. From 90 mm to 58", the Monster AGTT can be used for the tires of any vehicle—from compact agricultural equipment to the largest earth-moving machines. This patented jaw design ensures secure, damage-free clamping across the full range of wheel sizes, eliminating the need for multiple clamping systems or adapters.
The revolutionary S.T.S. device (Side To Side) enables the automatic switching of the tool block from one side of the tire to the other. This patented feature eliminates manual repositioning, dramatically reducing cycle time and operator effort. The system intelligently manages the transition, maintaining perfect alignment and tool-rim tangency throughout the entire tire changing process. This is automation at its finest—saving time, reducing fatigue, and ensuring consistent, high-quality results on every wheel.
The new mobile controller with very handy controls enables efficient operation of the tire changer without the operator touching the tools. The independent wheel-mounted ergonomic control unit (trolley style) makes the technician's job much easier, offering radio transmission of commands for ultimate flexibility and freedom of movement around the machine.
The controller features a display for setting wheel size in inches, an emergency button for instant stop capability, and operates on 24V power. At just 17.6 lbs (8 kg), it's lightweight and easy to maneuver, putting total control in the operator's hands without physical strain or awkward positioning.
