By Li Chenyu / hcfire360 April 2021
The size of the following picture of kelly bar is 630-5*26. The pile diameter is 630mm, total 5 sections, each is 26m. The diameter 630mm is the biggest piling diameter kelly bar up to now. This UNIDRILL kelly bar is worked with XCMG rotary drilling rig, the drilling bucket with rock bullet teeth is also manufactured by UNIDRILL. The construction site manager said that UNIDRILL kelly bar and rock drilling bucket helps them improve the working efficiency a lot. Hope our kelly bar could supply super service to more and more construction sites.
