Caterpillar adds power-shift option to 428E & 434E mechanical backhoe loaders

Caterpillar is providing increased customer choice and improved operator comfort, with the option of a power-shift transmission for its popular 428E and 434E mechanical backhoe loaders. The standard manual shift transmission will remain available for those customers who prefer it, while the power-shift box, already proven on higher specification E Series Caterpillar models, promises reduced operator effort and increased machine productivity. Caterpillar’s power-shift backhoe loader transmission provides four gear selection positions on the control lever. The operator simply selects the highest gear that is required by rotating the barrel of the steering column mounted directional lever. At higher forward travel speeds the transmission will automatically select a fifth ratio for a maximum 40km/h capability.

The transmission features hydraulic clutch pack modulation, to ensure that drive is taken up smoothly. This improves the ride for the operator on all types of terrain and reduces fatigue during travel between job sites. With no conventional gear lever mounted on the cab floor, there is improved access for the operator through the right hand door, along with more floor space for those with larger work boots. The performance and productivity of Caterpillar’s British-built E Series backhoe loaders was improved further recently with the introduction of a redesigned extending dipper stick, revised wear pads in the dipper and the stabilizer legs, a new roof cap and an improved instrument cluster in the cab. The popular 428E also benefits from a robust loader arm redesign that boosts durability and reliability in the toughest operating conditions. Front end breakout has also been increased and this, in combination with the smoother gear changing of the power-shift transmission, results in improved productivity and lower operator effort.
