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 (3700 kilograms). Each also has a two-section boom, delivering a 20-foot (6.1-meter) lift height on the TH406 and a 24-foot (7.3-meter) lift height on the TH407. The new telehandlers replace the TH220B and the TH330B in the Caterpillar line.
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 horsepower (74.5 kW), and in an electronically controlled configuration, which produces 125 horsepower (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 so that the operator can focus on getting work done. The powersynchro transmission and unique torque converter drive system ensures long, trouble-free life in tough applications. The advanced cooling system with optional reversing fan delivers excellent performance in all conditions.
The new Cat telehandlers incorporate load sensing hydraulics for superior 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.
Designed for operator efficiency and comfort
The TH406 and TH407 feature a new, spacious cab. The operator has superior all-around visibility due to larger window area. 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.
The new telehandlers are capable of three different steering modesâ€”two-wheel steer, circle steer and crab steer. Different modes allow for improved control and superior maneuverability in tight spaces. When changing steering modes, the wheels automatically realign to the optimum position.
Versatile and easier to maintain
A wide range of Cat work toolsâ€”forks, buckets, grapple tools and lifting equipmentâ€”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. Couplers provide superior sight lines to the tool.
The TH406 and TH407 offer reduced and simplified maintenance. Routine daily maintenance consists of simply checking the air cleaner indicator, hydraulic filter indicator, fluid levels and engine oil level in conjunction with a walk-around inspection. Service access points are conveniently located under the engine cover.
The TH406 and TH407 are sized to work productively and cost effectively in a variety of construction, materials supply, landscaping, nursery and agricultural applications.
