Lifting Devices TRIZ Cases
- Hitch-Mounted Lifting Arms With Slide Bar and Transit Locking
A slide bar, folding arms, and locking mechanism simplify hitch-based lifting while reducing manual effort and keeping heavy objects stable in transit.
- Ladder Support Structure for Single-Axle Fire Apparatus Reach
A torque box, pedestal, and support plate spread aerial ladder loads across the chassis, enabling long reach on a single rear axle.
- Resilient Rotary Encoder Coupling for Heavy-Load Turntables
A spring-loaded encoder coupling absorbs off-axis turntable movement, protecting rotary measurement accuracy in heavy-load transport chassis.
- Catenary Lifting Assembly With Vertical and Lateral Adjustment
A portable catenary lifting assembly adds vertical lift and lateral positioning for precise overhead line maintenance without vehicle-mounted hydraulics.
