SPEED
& FUNCTION
|
|
|
| This system is operated remotely. Sensors are fully integrated into the system components to allow the operator to monitor all critical process functions from a handheld console. Cut path programming can be performed above and below the surface. |

The demolition system is modular. All components required for work can be transferred from trailer to barge in a single lift. Gross weight of the skid mounted pumping unit is 12,500lbs. Multiple deployment floats can be used to expedite the procedure or for instances where pier shapes and sizes vary. |

Current removal rates vary from 10-50 sq.ft. of reinforced concrete per hour depending on the wall thickness, occurrence of steel rebar, and various system components mobilized to drive the cutting heads. Steel jackets to 3 inches can be processed at normal cutting speeds. |
|
|
Removal of a 38 ft. long, 7 ft. wide, 15 ft. high, submerged pier with 18 inch thick reinforced concrete walls, entails sectioning the structure into liftable sections. In this case, 10 sections weighing approximately 20 tons apiece, is required. Depending on equipment configuration, this separation and removal can be accomplished in as little as 14 working hours. |
