I plus di The TLB890 is the new top of the range 2WS backhoe loader from Mecalac. With impressive digging performance this machine has also been designed and built to last.
1
2 The Mecalac TLB890 is a simple and robust machine designed to ensure high performance with low running costs
A powerful excavator that offers dipper tear out force of up to 4110daN. The extendable dipper increases the working area significantly
4
3 The front loader offers a maximum bucket pin height of 3615m. Single bucket cylinder improves visibility to the bucket corners. Ride control is also available.
The new Mecalac TLB890 has an impressive turning circle (7m braked) considering its size and available performance!

6 All maintenance points are easily accessible. The engine bonnet opens easily and is independent of the loader arm position. Hydraulic hoses are coloured
The Perkins engine has a service interval of 500hrs. The exhaust aftertreatment uses a passive regeneration and has a service life of 8000hrs
7
8 The TLB890 features 8 LED work lights that ensure 360o visibility when working at night
The TLB890 can travel at 40km/h in total safety, thanks to the combined boom and slew transport lock, activated from inside the cab
9
10 Large ROPS and FOPS cab features and extended windscreen for high level visibility. The ABS roof reduces solar radiation. Servo excavator controls feature an ISO/SAE Switch
Hydraulic flow rate is proportional to engine RPM, at peak torque a flow of 100litres/min is achieved. The TLB890 can support a large range of hydraulic equipment

WITHOUT THOUGHTS Hydraulic oil is to be changed at 2000 hours, an appropriate figure considering the number of hydraulic attachments that a backhoe can work with. The engine oil change at 500 hours is in keeping with the times. Exhaust aftertreatment is performed with a passive regeneration at low temperatures, Perkins indicates a service life of 8000 hours for the DOC/DPF unit.
