I-shift with Crawler gears – Start where you want

I-shift with Crawler gears – Start where you want

I-Shift just got even more versatile and easy to drive. The automated gearbox is now available with the choice of one or two crawler gears, plus the additional option of extra reverse gears. If you transport heavy loads, you know that starting from a standstill can sometimes be difficult, especially in hilly terrain or poor road conditions. Ultimately, you may have to unload the cargo or even request towing, which has devestating effects on your uptime and productivity. Equip your Volvo FM with I-Shift with crawler gears and this will be a worry of the past. Your startability is dramatically improved, and the strain on the clutch is reduced by up to 75 percent, saving you from unnecessary repairs.

Reduce effort with the innovative control system

Just drive

I-Shift makes driving easier, safer and more comfortable. There’s no heavy clutch, and no stick to wrestle with. Every gear change is perfectly timed. The simplicity of the system reduces driver fatigue, helping you to focus on the road and the traffic around you. And if you do want to change gear manually, the button on the gearstick gives you direct control of the shift.

The system works in tandem with other features, for a smooth and effective driving experience

Save on fuel

I-Shift is designed to save fuel. The internal energy losses are low – lower than on manual gearboxes. But it’s the electronics that really make the difference. If you drive in Economy mode, every gear change is timed precisely, ensuring the engine works at the most efficient rpm. 
And when you descend, I-Roll disengages the engine, maximising the truck’s momentum.

The system is developed from an unsynchronised manual gearbox

How it works

I-Shift is based on a "classic" unsynchronised manual gearbox – hence its compact design and low internal losses. The magic happens in the electronic control unit that manages the clutch and shifts. By evaluating information about speed, weight, road grade and torque demand, it applies extreme precision to every shift. The system also communicates with the engine, allowing it to adjust the revs and brakes for best performance.

I-Shift can be controlled from a four-switch panel on the dash

Space-saving switches

I-Shift is so efficient, that you don’t have to use the gear stick very often. If you want to save precious space in your cab, you can get rid of the shift selector and opt for a four-switch control on the dash.

Crawl slow, run lean

Crawl slow, run lean

Can I-Shift with crawler gears really help boost your fuel economy? Sure. Because previously, you often had to be willing to sacrifice fuel economy for startability. But thanks to the crawler gears, we can now specify your truck with a faster rear axle ratio, allowing you to stay on cruising speed at much lower revs when you’re driving on decent roads. This lowers your fuel consumption by up to a couple of percent.

Perfect control in any direction

Perfect control in any direction

Low-speed manoeuvring is one of the most challenging aspects of the job. Thanks to a transmission ratio of up to 32:1 (and up to 37:1 in reverse), I-Shift with crawler gears let’s you drive at speeds as low as 0.5-2 km/h. You always have total control, making it easy to park with precision when you’re about to load or unload your cargo, and to avoid accidents that can ruin your day and your productivity. 

Say yes to more jobs.

Say yes to more jobs.

I-Shift with crawler gears adds to the versatility of the truck, letting you use the same truck for a host of different driving conditions and assignments. Drive both on-road and off-road? Need to transport extreme loads? Work at high altitudes? Special low-speed applications? No problem.

The crawler gear module only adds 120 mm to the length and 48 kg to the weight of I-Shift.
