Trolley Cranes TRIZ Cases
- Low-Construction Trolley Rope Fixing Point
Relocates the hoisting rope fixing point outside the drum vertical plane to enable symmetrical support and reduce twisting.
- Crane Trolley Hoist Synchronization Control
Master-slave control synchronizes crane trolleys and hoists, eliminating load sway caused by manual coordination.
- Gap-Jumping Overhead Crane End Truck Design
Segmented runways with standard doors restore climate control while multi-wheel end trucks bridge gaps for continuous loading operations.
- Height-Adjustable Crane Rails for Rail Vehicle Gantry Cranes
Hydraulic drive adjusts crane rail height to enable taller gantry cranes without breaching clearance profiles during transfer trips.
- Gantry Crane Parallel Spreaders Gravitational Energy
Gantry crane spreaders exploit gravitational energy to reduce consumption while increasing throughput.
- Cask Transport Device with Pivotable Wheel Struts
Pivotable wheel struts on a low profile frame allow cask transport devices to climb obstacles without tilting, ensuring stability during seismic events.
- Underground Nuclear Plant Hoisting via Rock Anchor Beam and Polar Crane
Segmented crane system transports large assemblies between irregular caverns, overcoming space constraints.
- Upright Lifting Large-Tonnage Box Girder Bridge Construction
Central lifting stations eliminate temporary roadways and reduce land use by positioning apparatuses below the bridge line.
