TOUGH ON WOOD
KIND ON THE PLANET

The TW 280HB HYBRID’s mild hybrid powertrain meets the dual challenge of exceptional 62hp peak chipping performance whilst using a 24.8hp Kubota Super Mini Series engine for outstanding applied torque.

FEATURES AND BENEFITS

BEST OF BRITISH ENGINEERING

Professional wood chippers need to be fundamentally fit for purpose. As no commercially-viable sustainable solution was available, we decided to lead our own hybrid powertrain development programme.

HOW DOES THE TIMBERWOLF HYBRID POWERTRAIN WORK?

SELF-CHARGING POWERTRAIN

When idling, the D902-TE4 turbo diesel engine directs energy into the Inmotion Generator Synchronous Motor (GSM) and drives energy recovery to the rotor (maintaining target RPM). During this period with no chipping load, the SECH supercapacitors are charged by the GSM as instructed by the Chipper Control Unit (CCU).

ENERGY BOOST ON DEMAND

When chipping starts, the rotor RPM naturally drops. If this RPM drops to a pre-determined set-point, the CCU will prompt the demand for additional energy. This is supplied according to the load mode automatically detected by the CCU based on the rate of decay.

CHIPPING POWER WHEN YOU NEED IT MOST!

This additional energy, stored in the SECH supercapacitors, is directed back into the GSM where it now acts to provide additional recovery energy to the rotor. The result is enhanced efficiency and chipping capability for the user when they need it most.
