The Thaler loader 4275 S is the top model of our product range. It weighs over 4600 kg and a 72 HP (53KW) – Yanmar engine makes working the driveline with all its well set-up components, so that the loader is really bursting with power.
He is big and heavy ... – big and heavy because of his physical appearance, the operating weight and its power, especially for us, accustomed to work with smaller HP.
but small as well …… - small in relation to the full-size wheel loaders with an operating weight of more than 5 tons.
It is strong ... - strong in terms of KW and/or HP, at least for us, because it is our strongest loader, we are building
But also 'weak' ...... – ‘weak’ when taking into consideration the seize of the product range of global players, certainly a subjective point of view.
For us, the 4275 is the largest loader and it has everything like the big ones, nothing to be jealous about, just in contrary, it also offers much, much more
in terms of safety = oscillating axle in the rear
in terms of breakout force: The Z-kinematics stands for it
in terms of space in the cabin - in all 3 dimensions: height, depth and width.
in one aspect, less is even more. It is the wheel loader with the shortest rear overhang in its category. This makes it more manoeuvrable and easier to drive, it does not swing at all when accelerating and driving at high speed.
