Efficient construction in a short time allows for early traffic opening!
The "LB Method" is an environmentally conscious construction method that results in a small construction area, a neat finish, and minimal waste such as debris, making it suitable for various situations. Using a manual hydraulic device called the "Frame Lifter," it allows for the direct lifting and removal of the iron cover frame from the road surface without prior work such as crushing or cutting the pavement, all while maintaining low noise levels. Additionally, since the frame is not bolted to the manhole body, future maintenance becomes easier. 【Features】 ■ Rationality: Environmentally conscious in various aspects, easy future maintenance ■ Workability: Simple and easy work, excellent workability and safety ■ Economic efficiency: Short-duration work by a small number of people, possible construction with small-scale equipment, improved durability *For more details, please download the PDF or feel free to contact us.
