If the digger needs to work on those poor working conditions with large work amount, you can choose a crawler digger. It the ground’s carrying capacity is high and the ground is uneven with multiple hollow and hard lump ore, a heavy-duty digger with narrow crawler is suitable. On the other hand, if the ground’s carrying capacity is low and the soil is loose, a lengthened digger with broad crawler should be chosen.

If the digger is used in the small project, such as road maintenance, irrigation and water conservancy, a common digger weighting between 20t-25t can meet the requirements.If the working amount is low and the working ground should be frequently changed, a rubber-tired digger can be used. A backacting shovel and long boom can be added to dredge the riverbed. Multiple working devices can be used according to the construction requirements, such as crowd shovel, backacting shovel, grab bucket, hydraulic hammer, and drilling hole.
