Product Overview
This product is a 3-meter bamboo fire ladder, model TDZ3. The main body is made of high-quality bamboo and conforms to the XF137-2007 "Fire Ladder" standard. The Bamboo Fire Single Ladder has passed type testing at the National Fire Equipment Quality Inspection and Testing Center and has obtained CCC certification from the Fire Product Conformity Assessment Center of the Ministry of Emergency Management. All test results meet the required standards.
Core Specifications
The working length is 3 meters, with a tolerance of ±0.1 meters. The minimum ladder width is 250 mm, with a tolerance of ±2 mm. The step spacing is 340 mm, with a tolerance of ±2 mm. The overall ladder weight is 8 kg, with a tolerance of ±1 kg. The Bamboo Fire Single Ladder has a practical size, is lightweight, and can be easily handled by one person.
Material Features
The side panels are made of natural bamboo, which is strong and environmentally friendly. The steps are also made of bamboo, ensuring good compatibility with the side panels and even stress distribution. The metal parts are made of high-quality materials and are galvanized or painted. The combination of bamboo and metal provides a balance of lightweight design and durability.
Structural Stability
The horizontal bending residual deformation ratio is at most 0.08%, far below the standard requirement of 0.15%. The step bending residual deformation ratio is at most 0.24%, meeting the standard requirement of ≤0.5%. Step shear strength meets the standard, with no breakage at the connections or on the steps themselves. During the warping test, all step feet remained in contact with the ground. The stair joint torsion angle is ≤9.5° forward and ≤9.0° backward, both within standard limits.
Stable Usage Performance
During the slippage test, no step feet shifted on the test surface. After completing the single-leg load test, the legs and connecting parts showed no loosening, damage, or deformation. Maximum cantilever bending deformation of the side panels was ≤1.1 mm internally and ≤1.0 mm externally, indicating minimal deformation. The residual deformation ratio in the side sway test is ≤0.11%, far below the standard requirement of 0.3%. The product demonstrates strong overall stability and meets the support requirements for firefighting operations.
Opening and Closing Structure Features
When unfolded, the steps form a standard right angle with the side panels, ensuring even stress distribution. When folded, the side panels remain flat without warping or skewing, resulting in a neat, organized shape. Unfolding and folding are simple and require no additional tools. The compact folded size facilitates transportation, storage, and on-site handling.
Workmanship Details
The steps and side panels fit tightly without looseness or the need for wedging. Metal and bamboo parts are closely joined without additional filling. Fasteners are installed vertically, without protruding nail heads, sharp edges, or burrs. Rivets are securely fastened with standard semi-circular heads. The outer surface is smoothly polished, free of burrs, and the bamboo has an orange-yellow finish. Surfaces are coated with non-conductive paint, evenly applied without missed spots or runs.
Matching Labels and Accessories
The side panels include a dedicated nameplate, clearly showing the product name, model, and other key information. Clear warnings guide proper operation. The Bamboo Fire Single Ladder bears official certification marks and is fully labeled. A dedicated instruction manual is included for correct use and maintenance. Packaging and markings comply with relevant standards, facilitating transportation and identification.
