The pump truck with 86-meter-long boom that was independently developed by Sany Group Co., Ltd.(600031.SH) officially got the Guinness certificate of "pump truck with global longest boom" on December 11, making three world records including the longest boom, the most boom sections and the highest pump displacement.

R&D workers disclosed that this pump truck adopted the 7-boom design for the first time in the world, having a wider and flexible work range compared with the 5-boom and 6-boom versions. 1200MPa high-strength steel plate was developed through innovation of the heating processing technology, thus solving the problems of high deformation and low impact toughness of boom high-strength steel plates. The pump displacement was increased from 230 cubic meters per hour to 240 cubic meters per hour, making a new world record in pump displacement.

Moreover, this pump truck with 86-meter-long boom adopted an all-terrain chassis with full independent intellectual property rights, breaking technical block of import chassis.

Four years ago, Sany's pump truck with 66-meter-long boom made the first Guinness record for Chinese engineering machinery industry and the company continuously set new records afterwards. Now, domestic pump trucks represented by Sany's products have fully replaced import products and the company's pump truck output ranks No. 1 in the world.
