HIGHLIGHTS

A standard fixture of the drive gear is its differential gear lock, which enables all four wheels to pull at the same speed. The trailer's set of drive shafts is provided with an overload clutch to deal with inadvertent overloading. The gear ratio between the tractor and the trailer has been adapted in the trailer's front-end gearbox, the gear ratio of the trailer being variable by changing a pair of gear wheels or the entire gearbox.

Kronos 140/160 4WDM

The Kronos 140 4WDM/160 4WDM forestry trailers have a sturdy set of bogey axles based entirely on mechanical transmission, with the power generated by the drive shaft being transmitted via a drive gear and a differential gear system to the bogie housings on both sides of the machine.

There is no give or disc cluth inside the bogey housing, the gears being in constant contact with each other. Road safety is guaranteed via multiple disc brakes.

When the trailer is being pulled with the power transmission off, the set drive shafts is disengaged, freeing the front-end gearbox from unnecessary rotation, and thus making the trailer easier to pull.
