Ladders TRIZ Cases
- Motorized Wheeled Ladder for Horizontal Repositioning
Motorized wheels rotate to reposition the ladder horizontally, eliminating manual relocation time.
- Multipurpose Ladder Thinner Rails Bracket Reinforcement
Strategically placed brackets reinforce thinner ladder rails to resolve the weight versus bending strength trade-off while maintaining ANSI safety ratings.
- Ladder Top With V-Gap Notches for Narrow Plank Stability
A plastic ladder top uses a segmented gap with V-shaped surfaces and notches to stabilize leaning against narrow rectangular planks and external corners.
- Telescopic Ladder Extension Support Friction Reduction
Roller assemblies in the extension support reduce frictional forces during aerial ladder extension, maintaining a coefficient of friction below 0.10.
- Folding Ladder Footstep Reinforcing Bar Structure
A reinforcing bar supports the footstep bottom to increase bearing performance and prevent deformation.
- Powered Ladder for Industrial Vehicles
Hydraulically actuated ladder assembly pivots from stowed deck position to vertical access using a motor-driven cylinder and linkage system.
