An all-around loader suited to the vast majority of roadside applications, the 234B can be equipped with a pull-through delimber, bar saw slasher, circle saw slasher or grapple saw for maximum flexibility. The strength-to-weight optimized boom system is designed to withstand the forces of high cycle delimbing and loading.

The efficient load sensing hydraulic system with swing priority and energy recovery delivers simultaneous power to all machine functions for high performance and response, while providing excellent fuel efficiency for reduced cost per tonne.

The Tigercat FPT Tier4 engine is perfectly matched to the duty cycle for added efficiency and high performance of the after treatment system.

The operating environment is quiet and refined with excellent climate control, a heated and cooled seat, window blinds and ergonomic controls.

The 234B is also available with the Tigercat AC16 articulating carrier for mill yard applications. Equipped with Tigercat’s WideRange™ drive system, the AC16 achieves high tractive effort to handle tough terrain and towing applications.
