THE new Cat TH336C, TH337C, TH406C and TH407C telehandlers incorporate a number of new features that increase performance, versatility, ease of operation, and serviceability.

“A choice of engines and transmissions allows customers to tailor these new models to their applications, and refinements in the implement and auxiliary hydraulic systems enhance performance and efficiency,” says a spokesman for Cat.

The fuel-efficient C4.4 engine is rated at either 74.5 kW (100 hp) or 93.1 kW (124 hp) and emits at levels equivalent to
EU Stage IIIA emission standards. Maximum lift height for the new models ranges from 6,096 mm (20 ft) to 7,315 mm (24 ft), and maximum load capacity from 3,300 kg to 3,700 kg. For optimum performance and added safety, each new machine has a long wheelbase, low centre of gravity and compact turning radius.

For optimum utilisation, the new C-Series models can handle a wide range of Cat work tools via the standard Integrated-Tool-Carrier coupler, and an optional hydraulic coupler allows the operator to change non-powered work tools from the comfort and safety of the cab. For powered tools, a selectable, continuous-flow auxiliary hydraulic system ensures productive performance.

The powerful implement hydraulic system for C-Series telehandlers features a new torque-regulated/load-sensing, variable-displacement axial-piston pump and a full-flow sharing valve that permits the operator to engage three hydraulic functions simultaneously.

The new hydraulic system provides enhanced value for the customer through increased production potential, fuel savings, longer component life and reduced sound levels.

Cat C-Series models are noted for their spacious, comfortable cabs that feature intuitive controls, including a single, low-effort, electro-hydraulic joystick that provides proportional and simultaneous boom functions and auxiliary functions, as well as directional and range controls for the new transmissions. Models with the 124 hp engine use the new 6F/3R transmission that provides travel speeds to 40 kmph. Models with lower-power engines use the 4F/3R transmission with travel speeds to 30 kmph.

Adding to the excellent controllability of the new Cat telehandlers is the three-mode steering system, which permits the operator to precisely position the machine, promoting job-site efficiency and safety.

To reduce routine maintenance and overall operating costs, the telehandlers feature 500-hour engine-oil change intervals, maintenance-free drive shafts, and grouped grease fittings for the rear-axle cradle and compensating cylinder.
