Wheel carrier KN-251 is a universal, high-performance earthmoving machine with hydraulic equipment and control of working organs. KN-251 was introduced in 1978 into the use of the Czechoslovak army.


It is designed to perform various earthworks on a larger scale:


- when securing movement,
- in the protection of technology and manpower,
- for engineering construction works.


Can do the following jobs:


- adaptation and construction of roads, including the removal of obstacles and non-explosive barriers, the removal of forest floods and snow,
- trenching work, including planting of objects and excavation of trenches by means of a trench plow (by towing),
- mining and loading of material (sand, stone, soil),
- material handling, including lifting and transfer of loads,
- emergency towing of low loaders and trailers for construction machinery,
- surface leveling,
- removal of masonry debris and landslides,
- creation of fire protection strips,
- for the treatment of fords and wading in a limited depth of water.


KN-251 is a two-axle vehicle with an articulated frame, on the front of which there are brackets for attaching work equipment with a universal bucket UL 3.


The work equipment with a shovel consists of:

- from a boom attached to the front frame,
- two hydraulic lifting cylinders controlling the lifting of the boom,
- a tilting mechanism that controls the position of the bucket.


The UL-3 shovel consists of:


- rear fixed part (blade),
- front pivoting part (jaws).


The cabin is all-metal, two-door, dustproof, mounted on the rear of the frame and is closed, equipped with heating and ventilation. The upper part of the cab is removable.
