T46-7 Telehandler
Sit in, drive off
Hydrostatic drive has been a feature of Liebherr’s construction machines for more than 50 years and allows operation to start immediately without disengaging the clutch, changing gears or braking. So that machines can always be manoeuvred safely on any terrain, there are various comfort functions: differential lock, disengage all-wheel drive (less wear and tear) and electronic selection of the four different steering modes.
Auto Hill Assist
This feature acts as a drive-off aid to improve safety on steep slopes, especially useful when taking loads off-road or towing a trailer. On inclines, the driver has only to take his foot off the accelerator pedal for the machine to stop and the automatic parking brake to activate. It releases again as soon as the vehicle restarts.
The parking brake is always electronically controlled via a switch in the cabin - there is no handbrake lever, like other manufacturers’ machines.
Manual Control Package
On the right-hand cabin console are two mini joysticks that control driving and operating hydraulics. They allow vehicle and engine speed to be set, as well as the appropriate litre capacity of the hydraulics, for setting continuous operation of, say, a sweeper attachment or concrete mixing bucket.

handlers – those with a payload up to 4.1 tonnes – that enables the boom to be lowered load-free. The system is already familiar to users of Liebherr's mobile and crawler excavators and uses gravity to return part of the hydraulic fluid in the cylinders. It is a preferred option for customers who carry out large numbers of loading cycles.
Comfort Drive
This feature can be regarded as a transition as technically, the option is on the telescopic boom, but the results take effect when driving. The boom is compensated by an automatic hydraulic counter-movement under uneven driving conditions. The option is activated automatically from 7 kph, but a toggle switch can be used for slower movements. Anti-vibration damping prevents rocking and is recommended for machines that will often be driven at speeds above 30 kph.
