Travelling Gear TRIZ Cases
- Fixed-Laser Crane Positioning for Anti-Skew Rail Alignment
A wall-mounted laser and crane reflectors prevent beam skew, enabling accurate overhead crane positioning and safer anti-skew control.
- Fixed-Wall Laser Positioning for Anti-Skew Crane Control
Stationary wall-mounted lasers measure crane distance to reflectors, reducing skew and helping keep the crane square to its rails.
- Trolley Traction Mechanism for Reliable Drive Force Transmission
A trolley traction mechanism transmits drive forces between spaced running wheels via a V-ribbed belt, preventing overloading and wear of the running gear unit.
- Modular Crane Undercarriage with Central Pot for Stability and Mobility
A crane undercarriage uses a central pot to connect detachable longitudinal beams to wheeled or crawler chassis.
- Hoist Trolley Control System Preventing Wheel Slip
A control system adjusts speed references for interconnected hoist trolleys using rated motor torques and nominal speeds.
- Hybrid Crane Driving Apparatus with Transfer Case Clutching
A hybrid driving apparatus for mobile cranes combines an internal combustion engine and electric machine via a transfer case.
- Portable Jib Mounted to Crane Girder for Load Positioning
A portable jib mounts to a crane girder using a wheeled base frame and support member to extend radial lifting reach.
- Crane Trolley Frame Segmentation and Pivoted Joint for Load Stress
Segmenting the trolley frame with a pivoted joint distributes torsional stress, reducing rope wear and enabling standardised components.
- Crane Force Conversion Unit for Manual Load Control
Force conversion unit converts operator-induced mechanical impulses into control signals, eliminating cumbersome remote panels and enabling precise positioning.
- Crawler Crane Segmented Lower Traveling Body for Transport Stability
A crawler crane lower traveling body uses separable lattice connecting portions to join the car body and crawler frames.
- Crawler Crane Boom Turn Restriction and Outrigger Gap Control
A crawler crane controller cancels boom turn restrictions when no operator is present to allow full rotation.
- Crawler Crane Cylinder Retraction Guide Mechanism
A guide portion directs the hydraulic cylinder rod front end to swing between retracted and operating attitudes along the lower boom.
- Head Block Sheave Transfer for Crane Maintenance
Selective sheave transfer between head blocks allows maintenance without removing the entire crane device, reducing downtime.
- Crane Monitoring Range Adjustment for Assembly State
A crane monitoring device dynamically adjusts its detection range based on the current assembly configuration of the structure.
- Suspension Crane Skew Detection and Correction
Mechanical sensor detects bridge skew to adjust drive speed, reducing measurement complexity.
- Three-Way Motion Compensation Lifting System for Offshore Vessels
Mobile carts on rails compensate for vessel heave, pitch, and roll to prevent mechanical collisions and maintain stable lifting efficiency.
