New engines and transmission for CAT telehandlers

CAT has now introduced changes and improvements to its 14 and 17 metre telehandlers - the TH414C, TH417C and TH514C.

The three new models form part of a new eight model C series range, and will be shortly joined by the 2.5 tonne/5.6 metre TH255C with a Deutz engine.

Maximum lift heights for the new models, which were revealed at Bauma, is 13.7 metres and 17.3 metres respectively, while maximum lift capacity is 3,700kg and 4,999kg. Power comes from a new 76 Kw/101hp Cat C3.4B engine that meets E.U. Stage IIIB emission standards, coupled to a new 4F/3R Turner powershift transmission, which features an independent oil supply to help maintain oil quality for optimum performance and reliability.

The controls, include a single, low-effort, electro-hydraulic joystick that provides proportional and simultaneous boom and auxiliary functions, as well as directional and range controls for the new transmission with road speeds of to 30 kph/18.6 mph.

The implement hydraulic system 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 system can also develop full hydraulic power at low engine speeds, facilitating the precise placement of heavy loads.

The new C-Series models can handle a wide range of attachments via the standard Integrated-Tool-Carrier coupler, and an optional hydraulic coupler allows the operator to change non-powered work tools from the cab.

These updated models are all built by JLG under the CAT Alliance programme.
