Today, as the urbanization process continues to accelerate, the increase in high-rise buildings, underground spaces and complex industrial facilities has put forward higher requirements for firefighting and rescue. Traditional fire trucks often seem to be unable to cope with these complex scenes. Therefore, designing a heavy-duty fire truck that can cope with future challenges has become an important direction for the development of firefighting technology. Based on the technical background of 2025, this article will explore the design drawings of an innovative heavy-duty fire truck and analyze its uniqueness.     1. Design concept: combination of intelligence and modularity The heavy-duty fire truck of the future is not only a "fire-fighting machine", but also a mobile rescue platform that integrates intelligence, modularity and multi-function. The core concept of the design drawing is "intelligent perception, rapid response, and multi-scenario adaptation". Through artificial intelligence, the Internet of Things and modular design, this fire truck can quickly switch functions in different scenarios to maximize rescue efficiency.         2. Appearance design: streamlined and high-strength materials In terms of appearance, this heavy-duty fire truck adopts a streamlined design, which not only reduces wind resistance, but also improves the aerodynamic performance of the vehicle. The body is made of high-strength alloy material, which can maintain structural stability in extreme environments such as high temperature and explosion. The roof is equipped with a retractable drone launch platform, which can quickly deploy drones for fire detection in the early stage of a fire.   3. Power system: hybrid power and all-terrain adaptation The power system adopts a hybrid design, combining the advantages of diesel engines and electric motors. The diesel engine provides strong power output, while the electric motor achieves zero emissions at low speeds and in urban environments.

  Designed Drawing for Aerial Fire truck ISUZU

  March 23, 2025

  The technical design drawings of the 38-meter aerial fire truck cover several key parts such as the vehicle structure, hydraulic system, electrical system, jet system and safety design, ensuring the vehicle's efficient, flexible and safe operation in complex fire scenes. Through continuous technological innovation and optimization, the 38-meter high-lift jet fire truck will play a more important role in future firefighting and rescue.   The Isuzu Giga 38-meter aerial fire truck is a fire-fighting equipment specially used for fire rescue in high-rise buildings, large-span spaces, petrochemicals, etc. Adopt Isuzu GIGA 6x4 or 8x4 cab truck chassis, FAST 12-shift gearbox, special for fire fighting appliction. Its core function is to raise the fire cannon or jet device to a height of 38 meters by raising the boom to achieve long-distance and accurate firefighting operations. This model is mainly composed of a folding telescopic arm structure, an electric remote-controlled fire cannon, a tank body and a second-class chassis. The boom is usually a multi-section telescopic design (such as a two-section arm, a three-section arm or a four-section arm), and an electronic remote-controlled fire cannon is installed at the end of the arm. Firefighters can flexibly adjust the spray angle at high altitudes through an electric remote control device to perform firefighting operations such as spraying, water spraying or foam spraying.       The telescopic movement of its boom is synchronized by a hydraulic cylinder, chain and guide wheel. The fire hose is fixed on one side of the telescopic arm and is telescoped and raised with the boom. The operator can control the telescopic and rotation of the boom through the electric control handle on the turntable to ensure the flexibility and efficiency of the firefighting operation. In addition, the 38-meter high-rise jet fire truck also has the ability to operate over a very long span, and can achieve three-dimensional coordinated operations and ultra-close pinpoint firefighting. It is suitable for complex fire scenes such as high-rise buildings, large-span spaces, and petrochemicals.   The following is a detailed analysis of its technical design drawings. 1. Vehicle structure design The vehicle structure design is the basis of the 38-meter high-lift jet fire truck, mainly including the chassis, lifting arm, turntable and cab.
