Note: Overhaul refers to a repair performed to restore the performance of the product and complete the specified functions. During the overhaul, the whole machine is disassembled and any parts including the basic parts can be repaired or replaced. During the paving operation, the paver can drive the tie rod according to the requirements of highway construction. When the paver spreads the surface layer twice or more, it should be able to ensure that the joints are tightly flat and the tie rods are normally driven. Without operating the steering mechanism, the straightness deviation of the paver on flat ground is ≤1.5m/50m. For a paver with automatic driving performance, its straightness deviation of automatic driving on flat ground is ≤0.1m/50m. The opening pressure error of the main oil circuit safety valve and overload valve is ≤0.2MPa, and the natural descending speed of the four-pillar hydraulic cylinder is ≤2mm/h. The symmetry planes of the active sprocket and the passive sprocket of the chain drive should coincide, and the offset should not be greater than 0.2% of the center of the two wheels. The hydraulic system should be able to ensure normal operation under the condition of ambient temperature of -20~35℃. The hydraulic oil temperature does not exceed 80C, and the rated voltage of the circuit system is 24V. When the voltage changes within the range of 0.8~1.25 times the rated voltage, the circuit system should be able to work normally. The electrical equipment should be able to work normally under the conditions of relative humidity of 90% and the ambient medium temperature as shown in Table 4. Table 4
