Crawler paver, a type of engineering machinery widely used in road construction, is widely used in the laying of asphalt concrete and cement concrete pavements.
La finisseuse sur chenilles, un type de machine d’ingénierie largement utilisé dans la construction de routes, est largement utilisée dans la pose de chaussées en béton bitumineux et en béton de ciment.
Its application scenarios:
a. Expressway and high-grade highway construction
Construction d’autoroutes et de routes de grande qualité
Crawler pavers are often used in road projects with high precision requirements, such as highways and urban expressways, because of their strong stability and high paving flatness.
b. Airport runway and large parking lot/Piste d’aéroport et grand parking
Since airport runways have extremely high requirements for flatness and compactness, the high stability of crawler pavers can ensure high-quality paving.
c. Mining and underground construction/Exploitation minière et construction souterraine
Specially designed mining explosion-proof crawler pavers can be used for underground concrete pavement laying, adapting to complex terrain and reducing safety hazards.
d. Thick layer paving and base construction/Revêtement en couche épaisse et construction de base
Crawler pavers have strong adaptability to base materials, such as stabilized soil, graded gravel, etc., and are especially suitable for thick layer paving.
e. Working in high temperature or harsh environment/Travailler à haute température ou dans un environnement difficile
The steel track design enables it to remain stable when paving high-temperature asphalt, reducing paving errors caused by thermal deformation.
Advantages:
a) High paving quality/Pavage de haute qualité
With high-density screed, the road surface is compacted evenly, and the paving flatness is better than that of tire-type pavers.
Hydraulic automatic track tensioning reduces the risk of deviation and improves straight-line driving accuracy.
Equipped with automatic leveling system to ensure longitudinal and lateral flatness.
b) Strong traction and adaptable to complex terrain/Forte traction et adaptabilité aux terrains complexes
The crawler design provides stronger traction and is suitable for slope operations.
Its adaptability to uneven roadbed is better than that of tire-type paver.
c) Good stability, reducing material segregation/
Bonne stabilité, réduisant la ségrégation des matériaux
The track has a large contact area and a small specific pressure, which reduces the pressure on the ground, prevents the machine from sinking, and reduces damage to the soft roadbed. It has small vibration when traveling at low speeds, and the spiral distributes the material evenly, reducing the risk of asphalt mixture segregation.
d) Strong durability and low maintenance cost/Forte durabilité et faible coût d’entretien
The steel tracks are wear-resistant and have a long service life, making them suitable for long-term high-load operations.
e) Strong adaptability/Forte adaptabilité
The paving height can be adjusted to meet different thickness requirements.
Large-capacity hopper and efficient conveying system meet the needs of continuous operation.
Disadvantages:
Poor maneuverability and inconvenient transfer.
Limited adaptability to extremely soft roadbed.
The manufacturing and maintenance costs are high, the crawler structure is complex, the initial purchase cost is higher than that of a tire paver, and components such as track wheels and track shoes need to be checked regularly, otherwise wear and tear will affect the paving quality.
The edge of the curve is not smooth. The turning radius is large, and the flexibility is insufficient on narrow municipal roads or sharp bends.
Tire paver, a paving equipment with a tire traveling device, is mainly used for paving operations of asphalt concrete or cement concrete pavement.
Application scenarios:
f) Urban municipal road construction/Construction de routes municipales urbaines
g) Paving of internal roads in factories and parks/Pavage des routes intérieures des usines et des parcs
h) Rural highway and low-grade road construction/Construction de routes rurales et de routes à faible pente
i) Cooperate with large pavers for collaborative work/Coopérer avec les grands paveurs pour un travail collaboratif
Advantages:
a) Strong mobility and flexible transition./ Forte mobilité et transition flexible.
It uses tires for traveling and has a fast travel speed.
b) Simple structure and low cost./Structure simple et faible coût.
c) High operating comfort, with electronic control system, intuitive operation. The cab is user-friendly, with adjustable control panel and all-weather protection canopy.
d) It has wide construction adaptability and is suitable for small and medium-sized projects such as municipal roads, sidewalks, and bicycle lanes.
Disadvantages:
a) The adhesion is low and thick layers may slip./L’adhérence est faible et les couches épaisses peuvent glisser.
b) The paving smoothness is slightly inferior to that of the crawler type./La douceur du pavage est légèrement inférieure à celle du type à chenilles.
c) Not suitable for soft roadbed or thick layer paving. When working on soft or muddy roadbed, the tires may get stuck, affecting construction efficiency.
d) The durability of long-term high-load operation is low.
Summarize:
Tire pavers and crawler pavers each have their own advantages and disadvantages. You should choose the appropriate model based on your needs and budget.
Les finisseurs à pneus et les finisseurs à chenilles ont chacun leurs propres avantages et inconvénients. Vous devez choisir le modèle approprié en fonction de vos besoins et de votre budget.
