Forward-Thinking Flexibility

A horizontally adjustable counterweight makes the High-Capacity Adjustable Wheelbase one of the most versatile forklifts in the industry. With just the push of a button, the counterweight can extend out hydraulically to dramatically improve the forklift’s maximum lifting capacity.

Need to navigate through a tight spot? Press another button, and the counterweight can be retracted just as quickly and easily, providing optimum mobility for the job at hand. Throw in a maximum lifting capacity of up to 80,000 lbs., and you have the perfect combination of power and finesse to handle the most diverse and challenging tasks imaginable.

Redefined Expectations

The heart and soul of every IC forklift is its drivetrain. Toyota’s High-Capacity Adjustable Wheelbase models are designed to provide the performance you need and the ability to fine-tune it based on the specific needs of your operation.

Not Your Typical Remote-Control Vehicle

Handling large, heavy loads in close quarters requires precision and expert control. That’s why Toyota’s remote-control option is available on all High-Capacity Adjustable Wheelbase models. With a remote control, operating the forklift from the compartment can be a thing of the past. Control of all forklift functions, including traveling, lifting, lowering, steering, and operating the counterweight extension, can be handled from an intuitive and easy-to-use handheld device, making precise positioning of delicate, bulky loads a breeze. A waist/shoulder strap attaches to the remote control, ensuring optimal operator comfort. When the remote control is not in use, it can be safely stored in the conveniently located storage compartment.

The most powerful forklifts in the industry just got smarter. The innovative MD4 display boasts 7 inches of total display space and is the first-ever touch screen display on a Toyota Forklift. Industry-leading functionality puts all the tools you need at your disposal. Access hydraulic schematics, wiring diagrams, and even operator and repair manuals with just the press of a button. Need to view critical information such as travel speed, engine oil pressure, or fuel level? The MD4 display is your glance-and-go solution for all these and more.
