Smooth operation methodDuring operation, the stability of the machine can not only improve work efficiency and extend the life of the machine but also ensure safe operation (put the machine on a relatively flat ground); the driving sprocket is more stable on the backside than on the front side, and It can prevent the final drive from being impacted by external forces; the wheelbase of the track on the ground is always greater than the wheelbase, so the forward working stability is good, and lateral operation should be avoided as much as possible; the digging point should be kept close

Low temperature will cause the excavator to have difficulty in starting and stopping. How to make it normally run under low-temperature conditions? Today Nicosail is here to help you! Overall inspection Before using the excavator, perform an overall inspection to confirm whether any parts are missing or damaged, and confirm that there is no alarm in the electrical system after power on. Check whether the hydraulic oil model can meet the ambient temperature; Check whether the amount of hydraulic oil is sufficient; Check whether the hydraulic oil is emulsified or blackened; otherwise, replace it. Check engine According to the current

It is challenging to backfill the soil in road construction, so we usually use small rollers with high construction flexibility. The following is a standard method of compacting backfill with a small roller. Ordinary rolling with mini road rollers The small-sized road roller shifts by hand in a direction parallel to the backfill center and gradually moves from the edge of the road to the road. Each rolling should overlap the previous rolling belt by approximately 10-20cm. Alternate rolling with small road rollers This method can reduce the rolling defects, such as the pushing of the mixture or the occurrence of
