Product Overview
This product is a 4-meter bamboo fire hook ladder, model TGZ4. The main body is made of high-quality bamboo and conforms to the XF137-2007 "Fire Ladder" standard. The Bamboo Pompier 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 4 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 10 kg, with a tolerance of ±0.5 kg. The product has precise dimensions, moderate weight, and is easy to carry and operate.
Material Design
The side panels are made of natural bamboo, which is strong and environmentally friendly. The steps are also made of bamboo, ensuring a tight fit with the side panels and even stress distribution. The hooks are made of 45# steel, providing high load-bearing capacity and resistance to deformation. The combination of a bamboo body and metal hooks balances lightweight design with robust support.
Structural Strength Performance
The horizontal bending residual deformation ratio is at most 0.13%, well below the standard requirement of 0.20%. The step bending residual deformation ratio is 0.20%, meeting the standard requirement of ≤0.5%. The step shear strength meets the standard, with no breakage at the connections or on the steps themselves. Hook strength is fully qualified, with no damage, deformation, or cracks after testing. The stair section torsion angle is ≤10.5° in both forward and reverse directions, within standard limits. The residual deformation ratio in the lateral sway test is ≤0.09%, far below the standard requirement of 0.3%.
Opening and Closing Performance
The Bamboo Pompier Ladder unfolds and retracts smoothly without jamming. The positioning device is reliably designed, ensuring stable fixation after unfolding without loosening. The hooks are securely attached, making the ladder suitable for various firefighting scenarios. The ladder is simple to operate and can be quickly deployed and folded by a single person.
Workmanship Details
The steps and side panels fit tightly without looseness or wedging. Metal and bamboo parts are seamlessly joined, requiring no additional filling. Fasteners are installed vertically, without protruding nail heads, sharp edges, or burrs. Rivets are neatly secured with standard semi-circular heads. The outer surface is smoothly polished, free of burrs, with an orange-yellow bamboo finish. Metal parts are galvanized or painted with a uniform, non-conductive coating, applied without any missed spots or runs.
Accessories and Labels
The side panels include a dedicated nameplate clearly displaying the product name, model, and other key information. Clear warnings guide proper operation. The ladder bears official certification marks and is fully labeled. A dedicated instruction manual is included to guide proper use and maintenance. Packaging complies with relevant standards, facilitating transportation and storage.
Advantages
The lightweight bamboo body makes the ladder easy to handle and set up. The 45# steel hooks ensure secure and safe connections. All product performance standards are met, fulfilling core requirements for firefighting operations at height. The rational structural design adapts to various complex working environments, making the product highly practical.
