3.Special Features of the POOYERT Rubber Tracks
- 3 Metal Cores Wound Up: Higher durability & Better flexibility
- Smaller Contact Surface (Smaller Lug): Better grip & traction
- Bi Directional: Tracks are Interchangeable
- Reinforced Edges Between Lugs: Decreasing the chance of slicing
- Jointless: Track is much stronger than the joint type

4. State of art technology

Thanks for endless our clients believe us and place the order to
us. So we have enough found to invest on R&D every year.
With several years research, we applied the Continuous Rubber Track inside the rubber track.
Continuous rubber track means the steel inside the rubber in
process is coherent which means there are no weld joint between the
steel. Comparing with common rubber track, Continuous Rubber track has some Performance Advantages as follow:
1: Good tensile strength
The framework of the continuous rubber track is wind-up by one,
single steel wire which offers a uniform a uniform tensile strength
for which increase the whole track's tensile stength.
2: Low elongation
Cause of the continuous structure of the track, the steel wire
internal hard to be elongated so that gives the track a very low
elongation.
3: Good anti-slip ability for steel wire internal
The steel wire under the continuous structure forced uniform during
the process of manufacture which makes the steel wire internal has
a good ability of anti-slip during the rubber track's working.
4: Stable dimension for pitch
The continuous structure assures low elongtion for rubber track
which makes the dimension of the pitch more stable.
5. Steel wire not easy to break
The continuous structure can offer a uniform tensile strength for
the steel wire internal which makes the steel wire not easy to
break and appear on the surface of the rubber track.
Since years, POOYERT makes use of the continuous steel-cable
technology in order to enlarge strength and resistance. POOYERT
rubber tracks are 40% stronger and long lasting, and the costs for
the customers are reduced.

5.Why choose rubber track?
*Less ground damage
Rubber tracks cause less damage to roads than steel tracks, and
less rutting on soft ground than steel tracks.
*Low Noise
A benefit to equipment operating in congested areas, rubber tracks
make less noise than steel tracks.
*High speed
Rubber tracks permit machines to travel at a higher speed than
steel tracks.
*Less vibration
Rubber tracks insulate machine and operator from vibration,
extending the service life of machine and decreasing operator's
fatigue.
*Low ground pressure
The ground pressure of rubber tracks equipped machinery can be
fairly low, about 0.14-2.30kg/m2, a major reason for its use on wet
and soft terrain.
*Superior traction
The added traction of rubber tracked vehicles permits them to pull
twice the load of wheeled vehicles of the same weight.
*Light machinery weight
Rubber track's pulling performance being twice that of wheels, it
permits the lighter vehicles equip with rubber track to do the same
pulling work than that of wheeled vehicles.
