Concrete removal on bridge substructures and other elevated structures poses several problems, including personnel access, equipment access, project staging, and logistics. Rampart’s self-designed High-Reach Robot solves these problems – whether the area to be repaired is above grade or below grade. In fact, we have removed concrete from 6-feet below grade to 50-feet above grade!
We added hydrodemolition cutting heads, robotics, and remote controls to a high-reach boom. By incorporating seven hydraulic devices, we are able to control the cutting nozzle in three dimensions to safely and efficiently remove concrete from hard-to-reach areas. To improve monitoring and performance, the operator can control the robot from within his own lift.
This robot’s unique cutting head can be positioned to perform removals on vertical and overhead surfaces. Walls, bridge substructure, columns, piers, dam faces and spillways have all had concrete removal successfully performed using our High-Reach Robot.
Several projects (Blanchette Bridge and Blanco Dam) using the High-Reach Robot were recently featured in the May/June 2016 ICRI Concrete Repair Bulletin. The article entitled “Hydrodemolition – Forget the Flat Work” was written by Pat Winkler.
