Caterpillar Showcases Next-gen 548 Forest Machine

The new Cat 548 next generation forest machine features several design upgrades for tree work and rugged environments.

“The 548 earned a reputation for reliable performance,” said Brent Uitermarkt, vice president for Caterpillar’s forestry products. “The next generation 548 will take it to an even higher level.”

Engine and Operation

Available in Log Loader and General Forest configurations, the new 548’s C7.1 twin turbo engine produces 30% more power than the previous series’ engine, enabling the new electrohydraulic control system to deliver 30% more swing torque. Updates to the drive system increase travel speed by 10%, helping the machine cover ground.

Smart mode automatically matches engine and hydraulic power to working conditions. The machine features cold-start capability of -25˚ F (-32˚ C) and high ambient temperature capability of 126˚ F (52˚ C).

Comfort and Safety

The new Certified Forestry cab with its reinforced structure and 1.25-in. (32-mm) thick polycarbonate windshield supports operator safety. The cab is available in a choice of rear or side entry. A standard rearview camera promotes visibility as do three available cab risers – 22-in. (558 mm), 48-in. (1219 mm) and 72-in. (1829 mm). The available Cat lock cab tilting system on the Log Loader configuration facilitates transport.

The machine has a new dual HVAC system for working in the summer heat or during subfreezing ambient winter temperatures. Its insulated roof and window and door seals keep in-cab noise levels low.

Operators can start the 548’s engine with a simple push of a button or available Bluetooth key fob and unique Operator ID. Operator ID allows each operator to program and store their own machine settings and attachment function preferences. A 10-in. (254-mm) high-resolution touchscreen monitor delivers navigation through operating menus and includes a digital version of the operator’s manual for reference. An available Cat PL161 attachment locator assists in finding work tools within a range of 200-ft. (60 m), even when covered by overgrowth or debris.

Maintenance

Compared to the previous model, the 548 next generation forest machine will consume 50 fewer filters over the course of 12,000 hours.

“We improved our filters and our service intervals, and we improved ground-level access to service points to make daily maintenance quick and safe,” said Uitermarkt. “Our new electrohydraulic control system eliminates the need for a pilot filter and pilot oil altogether.”

Fuel filters feature a synchronized 1,000-hour change interval – double the service life of the previous model. A new hydraulic oil return filter delivers a 3,000-hour service life, which is 50% longer than previous designs. The cooling fan runs only when necessary; and reversing intervals are programmable to enable the fan to keep the radiator cores clean.

Technology

Product Link technology captures operating data, fault codes and machine location information for fleet management. When within cell coverage, the machine’s new remote troubleshoot feature analyzes the data captured by Product Link and can share it with the Cat dealer. Owners can also be sure the 548 is operating with the most current version of software with standard remote flash, which updates machine software around the production schedule.

“More production, greater comfort and safety, and lower maintenance cost is what loggers can expect from our new 548,” said Uitermarkt. “Add in dealer network that’s dedicated to the forestry business and you get a winning combination of machine and support that really can’t be beat.”
