ses,etc.,while the three-piece boom is mainly applied in demolishing high-rises.Long reach

booms offered could fit various excavator models ranging from 20  to 120 metric tons.


   About the boom offered, improvement has been made firstly with proper selection of mater-

ials and thickness after analysing the stress concentration part through FEM assisted by 

CAD system. Secondly,the inside buffer plate is used to support tensile loads, which will 

prolong the lifetime of the boom and also the excavators. Thirdly,ultrasound wave inspection 

is applied to check faulty welding points during the inspection. Finally,in order to further 

confirm the machine reliability, extensive operating trials have been conducted under differ-

ent working sites.
