Recently, Jiangsu Great Crane Machiner•↑y Co., Ltd. (hereinafter ref♠♣£βerred to as "LDT"); Co₽↓✘mpany” ）The robotic armεδ≈  underwater fixed-point soil sampl​→απing robot, which participated in th↔£₽φe construction, officially appeπ♠♠ared at the construction si &←‍te of the 5th pier sinking w‌φ≈ell of Changtai Yangtze River ₹"¶¥Bridge. This is another ☆&intelligent equipment supplied by ¶•the company, following the specia →Ωlized gantry crane f≥♦or caisson construction and ‍ the intelligent monitoΩ§₽♣ring system for caisson cλ♥onstruction.

The underwater soil retrieval rob₩γot for deep water ca→α>σisson foundation is innovatively devel Ω×πoped and invested in by CCCC✘♣"✔ Second Harbor Enginee₩'ring Co., Ltd., and jointly manufactu"✘red by our company and Shanghai Zhenhu₹Ω♠↑a Heavy Industry. On August 25th≈'λ, the lower structure of t₩ he robot developed by Zhenhua Heavy‌♣¶ Industry was sent to the company fo✘<r final assembly with the®‍¥♣ upper structure manu↓§factured by the company, and factory ≥¥debugging work was carried out. After ¶©≈σjoint inspection by all↑α★↑ parties involved in the con¥★"struction, it was shipped to the 5£∑th pier caisson of Cha¥&∞ngtai Yangtze River ↓©≤Bridge for on-site inst‍£allation, for use in bδγ'Ωlind spot excavation operation₩₹s.

The robot operates in a water ♣γ©depth of over 70 meters¶λπ‌, and the soil breaking robotic arm ♠λcan achieve 360 degree full rotat≥ ion operation with a maximum opera§  ting radius of 8 meters. It consists o♣♠f an upper platform, a lifting♠® double cable winch, a working robot bo<≥dy, and hydraulic, electrical &€ 'and other systems. During opeΩ•↔ration, the robot body is lowered i¶×nto the underwater main tower pi↔€er, and the four oil cylindδφers of the body frame work to push "↑the main tower pier, in order to ma•Ωπ☆intain the balance of the•≥ body and achieve the support functio‌↓↑n of soil breaking and mill↓¶↓¥ing. The milling cutter head un★$der the body is driven by the robotic a λ'rm to perform soil break§×ing operations.

Jiangsu Grete, as a well-known lif€✔✔<ting machinery suppl®€ier in the Yangtze Riveβ↓r Delta region, actively pa§'rticipates in major local co ∞nstruction projects. In tσ‌&he construction project of $εthe Shanghai Suzhou Nantong♠☆↕₽ Bridge, which officially opened in↑¥ July this year, equipmen∑¶t such as 1800 ton gantry cranes and va←₹♦'rious types of gener¶≤¶₩al-purpose gantry cranes were suppl∏&ied. The company adheres to the λ∑innovative development concept advoλγcated by the country, cooperates c£λε♠losely with the bridge construction pa↕₹✔rty, integrates traditional♦®  construction methods with advancedα₽δ technology, promotes intγα↑elligent construction, and helps b₽&ridge construction improve ®✔↕$in risk control, difficult points,♥  and other aspects.
