Type, performance and application of bucket | ||
Type | Capability | Working Environment |
Standard Bucket | Standard thickness plate and high quality tooth plate | Applicable to light working environment, such as the excacating of clay, sand and loamy gravel. |
Heavy duty bucket | Thicker plate, higher quality tooth plate which can lasting the using time. choose domestic wear-resistant plate as cutting edge and side cutters, to reach high abrasion and bending ability. | Applicable to heavy environment, such as the excavating and loading of hard soil, soil rock, second hard rock, weathered granite. |
Rock Bucket | Add strengthen plate in the bottom, add side protective plate and protective plate. to rech high abrasion and bending ability. and choose domestic bucket teeth and adaptor for the bucket. | Applicable to heavy environment, such as the loading of hard stone and ore after the blasting. |
