Derricks/Masts TRIZ Cases
- Modular Crane Foundation With Ballast and Pedestrian Passage
Reusable metal base elements and ballast replace concrete crane foundations while keeping sidewalks open through an integrated passage.
- Hybrid Hydraulic Drive for Electric Rock Drilling Rigs
A common electric motor and hydraulic pump power tramming and drilling actuators, cutting power electronics while preserving precise control.
- Directional Drill Accessory Sockets for Stable Tool-Less Mounting
Two spaced sockets with tool-less locking let a directional drill mount heavy accessories securely and move its own trailer on-site.
- Drilling Rig Route Selection for Forward-Backward Approach Planning
Calculates forward and backward drilling rig routes, then selects the best path to avoid sharp turns, obstacles, and wasted time.
- Track-Mounted Drill Rig Alignment Using Turning Trajectory Feedback
Aiming-point trajectory monitoring lets a track-mounted drill rig turn into target alignment, improving inclined-hole drilling accuracy and efficiency.
- Drilling Rig Route Selection Across Multiple Approach Types
Calculating forward, backward, or sideways rig routes helps avoid drilled holes and obstacles while cutting fuel use and travel time.
- Internal Composite Dowels for Localized Tubular Reinforcement
A flexible sleeve filled in place forms an internal dowel that reinforces degraded tubular sections while reducing material use and repair effort.
- Composite Internal Dowels for Marine Tubular Reinforcement
A flexible sleeve filled in place forms a composite internal dowel that reinforces degraded marine tubular sections with less material and labor.
- Adjustable Drilling Jig Assembly for Precise Bolt Cage Positioning
Telescopic spokes and slidable yoke supports let drilling rigs position bolt cages and concrete forms accurately across varying pile setups.
