Benefits of technology

This innovation allows for easy installation without requiring any special tools like drilling holes through steel plates that are used during construction work. Additionally, this design prevents damage from rainwater while still allowing for smooth movement over uneven surfaces such as roads. Overall, these technical features make them more efficient than existing designs with fixed frames attached onto the moving parts of the hoist rower' s legs.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to prevent damage caused when there's sudden increase or decrease in air pressure on large structures such as industrial buildings during high-wind conditions that can cause them falling over from their tracks onto other floors below.
