The Tier-3 makeover of Caterpillar’s TH220B and the TH330B telehandlers resulted in new models TH406 and TH407. Both have rated capacities of 8,100 pounds and two-section booms, but the TH406 has a 20-foot lift height and the TH407 lifts up to 24 feet high. A mechanically controlled Cat C4.4 diesel engine produces 100 horsepower in the TH406, and an electronically controlled version of the engine delivers 125 horsepower in the TH407. Cat says load-sensing hydraulics offer superior lifting and digging forces as well as the ability to operate all three boom functions simultaneously and proportionally. Breakout force has been increased and Z-bar linkage is intended to improve digging performance.
