JCB’s popular telescopic boom wheeled loader range has taken a huge step forwards with the launch of the TM320 and the TM320S. These two machines are powered by Stage IIIB compliant JCB Ecomax diesel engines and revised drivelines for increased productivity and efficiency.
Replacing the TM310, the TM320 models benefit from a cab refresh with revised styling and a new instrument cluster. The TM320S delivers increased power and hydraulic output for faster cycle times and increased productivity, while a repositioned front axle provides both models with 100kg of increased lift capacity.
“Customers in agricultural markets and in the waste sector and really appreciated the power and reach of the TM310,” said JCB’s chief innovation and growth officer, Tim Burnhope. “With the TM320 and TM320S, JCB has moved the game on again in many areas, providing increased capacity, greatly improved comfort for the operator and additional productivity, all powered by our world-beating JCB Ecomax engines.”
The TM320 uses the latest JCB Ecomax diesel engine that meets Stage IIIB emissions standards. JCB has developed an innovative combustion process, utilising variable-geometry turbocharging, high-pressure common-rail fuel injection and cooled exhaust gas recirculation to reduce emissions from the engine. This means that there’s no requirement for diesel particulate filters or exhaust after-treatment additives.
The TM320 uses the 4.4-litre Ecomax engine, delivering 125hp and 550Nm of torque, while the high production TM320S comes as standard with a 4.8-litre Ecomax engine offering 145hp.
The JCB transmission features simplified control modes, offering the operator manual or automatic selection of gears. Torque converter lock-up is available in gears 4, 5 and 6 in the TM320, while the TM320S offers lock-up in gears 2-6. They deliver rapid acceleration and strong hill climbing ability with no loss of power, a feature well suited for working on a silage clamp. Customers can expect to see fuel savings of up to nine per cent. Both front and rear axles have epicyclic hub reduction with a choice of Max-Trac torque proportioning or limited slip differentials to suit the operation.
The front axle has been moved forward by 50mm, which makes the rear counterweight more effective and permits a higher payload of 3,200kg, up 100kg compared to the TM310. Customers can specify an optional headstock to allow the machines to work with the full range of wheeled loader attachments, adding to the versatility of the TM concept.
Variable-displacement piston pumps provide 140 lit/min of flow in the TM320 and a higher 160 lit/min in the TM320S. This 14 per cent increase in hydraulic flow results in faster cycles times, boosting overall productivity, particularly with high-flow hydraulic attachments such as large sheer grabs and bale spreaders. Both machines have fully proportional controls on the right-hand joystick and there’s now an option of two boom-mounted auxiliary hoses with an in-cab changeover switch. The auxiliary flow control has been simplified with an on-screen display of flow rates that can be adjusted on the move to match the attachment.
The new models are easily identified with striking, robust exterior and revised cab interior updates. At the rear of the machine the new bonnet offering the same excellent visibility behind the machines as before. Inside the cab a revised instrument cluster provides clear, easy-to-read information for the operator, including a new display for the auxiliary hydraulic flow rate.
Noise levels have been reduced, thanks to a variable-speed cooling fan. All transmission control functions are now integrated into the main joystick lever head, while transmission dump has been moved to the foot brake, allowing the operator to maintain contact with the lever at all times while driving, increasing safety and reducing fatigue. JCB’s proven Smooth Ride System can now be activated on the move via a simple rocker switch on the control console.
