Paver Classification By Walking Method

1.Drag type: Various work devices are installed on a special rack, and are laid by other machines for paving work. The structure is simple, the operation is convenient, but the paving ability is small and the quality is low. It is mainly used in small-scale construction and maintenance operations.

2.Self-propelled: has its own power unit, walking part and control mechanism and working equipment. The structure is complex and the volume is large, but the paving quality is high and the working ability is large. It is mainly used in the construction of new and large high-grade highways.

The self-propelled paver machines can be divided into two types, a tire type and a crawler type, depending on the traveling device.

1. Wheel type paver machine: small paver machines often use wheeled walkers, it mainly relies on rubber tires to support the whole machine and provides adhesion. Generally, the front axle is a solid small tire and the rear axle is a pneumatic tire. It is characterized by fast walking speed and good maneuverability. The edges of the paving layer are smooth when paving the pavement, but slipping occurs when the paving surface is wide.

2. Crawler paver machine: It relies on the track to support the machine and provide adhesion. The track reduces the pressure on the ground and prevents damage to the non-hard foundation or the underground sand layer, and the work performance is stable and widely used.
