Caterpillar Updates Telehandler Line with TH406, TH407

The Cat TH406 and TH 407 telehandlers feature a number of new systems and designs to enhance performance, promote operator efficiency and machine productivity, expand versatility and keep service time and costs to a minimum. Both machines have a rated load capacity of 8,100 pounds. Each also has a two-section boom, delivering a 20-foot lift height on the TH406 and a 24-foot lift height on the TH407, which was displayed at World of Concrete. The new telehandlers replace the TH220B and the TH330B in the Caterpillar line.

The TH406 and TH407 are sized to work productively and cost effectively in a variety of construction, materials supply, landscaping, nursery and agricultural applications. Both telehandlers are powered by the Cat C4.4 diesel engine, which meets U.S. EPA Tier 3 emissions requirements. The turbocharged, aftercooled engine is available in a mechanically controlled configuration, which produces 100 hp (74.5 kW), and in an electronically controlled configuration, which produces 125 hp (93.1 kW).

The power train also features a limited slip differential fitted in the front axle. The system enables the telehandler to work in difficult underfoot conditions, and it engages automatically. The powersynchro transmission and unique torque converter drive system ensures a long life in tough applications, the company says. The advanced cooling system with optional reversing fan delivers performance in all conditions.

The new Cat telehandlers incorporate load sensing hydraulics for lifting and digging forces and for the ability to operate all three boom functions simultaneously and proportionally. Smoother, logical control of the boom and work tool enables the operator to do more, more efficiently and more accurately. The new telehandlers also feature Z-bar linkage and greater breakout force for stronger digging performance compared to the previous models.

The TH406 and TH407 also feature a new, spacious cab. Large windows give the operator all-around visibility. Control placement and single electro-hydraulic joystick control of hydraulics ease the burden on the operator. A transmission disconnect button on the joystick allows the operator to route engine power to the boom for faster boom operation.

A new dashboard features an interactive liquid crystal display that shows machine functions such as engine speed, machine speed, selected gear and direction of travel, and fuel level.

A wide range of Cat work tools—forks, buckets, grapple tools and lifting equipment—equip the telehandlers for multiple tasks with different types of materials. The Caterpillar manual quick coupler is standard and allows the operator to change work tools quickly. An optional hydraulic quick coupler allows the operator to change work tools quickly and efficiently without leaving the cabin.
