Integrated Intelligent Control Robotfor Steel Supportin Foundation Pits

Zhejiang Hangzhou Science and Culture Center Underground Space Project, 2025
It incorporates OVM's independently developed Integrated Intelligent Control Robot for Steel Support in Foundation Pits.
This robot features high integration, compact design, battery-powered operation, and comes equipped with 24-hour cloud platform monitoring capabilities. It can autonomously perform compensation and adjustments.

LSD Hydraulic System

Shanghai Vertical Excavation (Shield Tunneling) Underground Smart Parking Garage Project, 2023OVM's independently developed LSD Hydraulic System to achieve intelligent synchronous lowering of 5000-ton well rings to a depth of 60 meters.

Prestressed Twin-String Beam Support System

Shanghai Fengxian Middle School Relocation Project Test Section, 2023
It adopts OVM's independently developed Prestressed Twin-String Beam Support System. This system features high strength, safety, reliability, and a short construction cycle. Its support force can be compensated in real time, providing ample excavation space.

Compact Tunnel Partition Wall Module Installation Equipment

Shanghai Airport Link Tunnel Project,2023
It incorporates OVM's independently developed Compact Tunnel Partition Wall Module Installation Equipment. This equipment, designed as a gantry system, can complete tasks such as pin insertion/removal, lifting, rotation, lateral movement, and lowering. It occupies minimal space, doesn't hinder the passage of construction vehicles on both sides, and effectively shortens the overall project duration.

Three-Way Adjustment Equipment for Accurate Positioning of Curved Elements

Shanghai Airport Link Tunnel Project,2023 It features OVM's independently developed Three-Way Adjustment Equipment for Accurate Positioning of Curved Elements. 
This equipment offers X/Y/Z three-dimensional adjustment capabilities, enabling loaded movement, steering, height, and slope adjustments to achieve precise positioning with a single-button intelligent operation.
