Terex has introduced the TLB890 backhoe loader which features a curved boom, an internally extending dipper and higher hydraulic pressures for increased performance.
Tandem gear pumps deliver 160 litres/minute of oil at 250 bar that combine with high-force hydraulic cylinders to provide the backhoe bucket with 60.3 kN of breakout force in ‘Speed Dig’ mode.
With ‘Power Dig’ selected and the heavy-duty bucket fitted, the breakout force increases to 67.8 kN that tops most of the competition.
Dipper tearout on the TLB890 is 41.1 kN for the standard dipper and also with the extending dipper when retracted.
With the dipper fully extended, the maximum dig depth is almost 5.7 m while tearout drops to 29 kN – figures compare favourably with most other manufacturers’ machines.
Curved boom and cast iron ‘hard nose’
A new curved boom design allows trucks to be loading closer to the machine to reduce cycle times and a new cast iron ‘hard nose’ provides additional protection for the 74.5 kW Stage 3A Perkins engine.
The four-forward/four-reverse Synchro Shuttle manual gearbox is standard with the option of an auto/manual Servo Power Syncro (SPS) transmission that has 9 per cent less drag for increased performance and fuel economy.
Revised front axle steering geometry makes steering and manoeuvring around the work site easier, while the rear axle’s outboard planetary gears give a 41 km/h maximum travel speed and large diameter wet discs minimise pedal effort when braking.
The TLB890 is available with SAE, ISO or cross-pattern mechanical levers or with the optional pilot controls that also get thumbwheels on the joysticks to control the dipper extension and any attachments.
It also gets a new enlarged cab with an ‘up and over’ rear window, reach and rake adjustable steering wheel and a mechanically suspended seat.
