Val-Bearing Catalogs

Chains / Caterpillar

TAGEX is a general importer of DONGIL tracks for Europe and VAL-BEARING, S.L distributor. With an annual manufacturing of currently 60.000 caterpillars, DONGIL one of the largest and most proficient manufacturers all over the world.

DONGIL tracks are used in original equipment and later refits, because they stand out for their high quality.

This is how TAGEX supplies popular European manufacturers, general distributors, manufacturers outside Europe and the spare parts business in Europe.

TAGEX stocks all over Europe the current types and sizes of excavator tracks 180 up to 500mm wide.

Track structure and dimensions

  • track width:
    It is measured in millimeters.
  • step length:
    It is measured in millimeters.
  • Corresponds to the distance between teeth:
    number of teeth.
Indicates the number of internal teeth with which the caterpillar is equipped.
When giving the measurements of a caterpillar, they are indicated in this order:

track width (mm) x number of teeth x length of step (mm)

Ej. 230 x 43 x 72 corresponds to a caterpillar 230 millimeters wide,
43 teeth and 72 step millimeters.

maintenance recommendations:

After each use the caterpillar should be washed.. Especially the inner part where you can find remains of asphalt and mud. It is also convenient to wash the caterpillars with the help of a high pressure machine..
Oil, hydraulic fluid, etc. they can attack the rubber. Therefore, contact with these substances must be avoided..
Examine the rubber tracks and the other parts of the drive that are in direct contact with the function and wear. excessive wear, strange, irregular or only in one part can reduce the duration of the track.
Track tension should be checked every 50 work hours, especially after a track change.

correct circulation:

On terrain with edges that can make cuts to the caterpillar, uneven or abrasive surfaces avoid high speeds or fast turns, In addition, the radius with which the curves must be taken must be greater.

Track storage and care:

If it is possible to store the caterpillars indoors or cover them to protect them from inclement weather such as the sun, rain and snow.
It is convenient to move the caterpillar from time to time so that it does not suffer from a long one-sided load.

Short Pitch Tracks

With the introduction of heavier machines at the beginning of the years 90 the steps of the caterpillars also grew with a long step (Long Pitch) of 96 mm up 163 mm. Shortly after the introduction of these steps it was observed that they were too long and that the tracks could not function correctly., going on to divide them in two and design the caterpillars of short pitch (Short Pitch) that are fully compatible with long pitch tracks.

The steel elements that are embedded in the long pitch tracks are too bulky to work smoothly and therefore cause a lever effect that rhythmically lifts the machine, causing excessive fatigue. When long distances must be covered at high speed, the caterpillars suffer due to the collapse in the small flexible areas, causing heating and the caterpillar eventually becoming more brittle..

The short pitch tracks by inserting twice as many steel elements that are only half as large allow an optimized drive of the components. The machine moves less and runs almost vibration-free. The caterpillars suffer less and therefore their duration increases. Since 10 years our caterpillars are all short stride.
