Main Components Description

Aerial ladder

The ladder uses a telescopic truss structure with four sections and each section is welded by high strength steel. The pre-deformation technology of the arc ladder is used to offset partial deformation after the whole ladder is loaded, so as to improve the safety of the ladder frame and the stability of the expansion. The telescopic system consists of a winching system and a 2-wire rope system and each section of the ladder is driven by two sets of wire ropes, realizing synchronous telescopic of the ladder truck.

Working platform

The working platform is in high strength steel frame structure; you can achieve a variety of actions on the platform; a fire water monitor was equipped to realize aerial and long-range fire; talk back equipment is installed to communicate with the ground staff.

 

The platform leveling adopts electro-hydraulic proportional control technology to realize continuous and smooth leveling of the platform. The emergency manual leveling function is set up. The emergency manual leveling adopts a single foot treading type, so the leveling of the work platform can be realized simply by continuously pressing and leveling the foot lever and the operation is simple and convenient.

Slew drives

The turntable Slew drives works in double-side and double-vertical plate box-structure; a slewing system driven by a hydraulic motor is arranged at the right side of the turntable. A planetary gear system is used, the turntable can be continuously rotated by 360°, and the turntable can work stably. The elevating cylinder is placed at both sides in the turntable. A superstructure console is set on the left and is the vehicle main console. The turntable console is installed with adjustable leather seats. Operations become more comfortable.

Sub-frame

The large-scale box-structure is welded with high strength steel plate, which is light in weight and strong in strength; the fuel tank is placed inside the sub-frame box body to save space effectively; outriggers in H-shaped are set to effectively improve stability of vehicle operations and reduce deformation of the sub-frame. The outrigger has two modes: manual leveling and computer automatic leveling. The leveling accuracy is high and the leveling speed is fast.

Electrical system

The whole machine adopts an electro-hydraulic proportional control system. Main electrical components are imported and provide high stability. The vehicle is provided with 4 operating devices: chassis console at the rear of the vehicle, controlling outrigger beams and jack cylinders; firefighting system console, controlling fire water supply system, water pump operation and foam mixing chamber; superstructure operation system including a turntable console and a working platform console, helping realizing turntable slewing, boom elevating and telescoping, and fire monitor remote operation.

The wired intercom device is used between the turntable operating platform and the working platform console. A console shall have a variety of control function switches and parameters. Lighting devices are set at night, an anti-reflective function is used in the sun, and operating signs are displayed.

In addition to the control of vehicle movements and automatic vehicle protection devices, the electrical system is equipped with the following signal lamps and head lamps: search lamps for the boom, working platform, and water monitor; outrigger flashing warning lamp; external lighting and signal devices for fire vehicles conforming to national standards.

Hydraulic system

The main system uses a pressure/flow automatic variable pump. The main control valve uses the imported load sensitive control valve and forms a closed core load sensitive control mode and constant pressure control mode, together with the variable pump, to achieve the slewing of the superstructure, boom elevating, telescoping, and crank arm elevating actions. The system is started under low pressure, saves energy, and is efficient. Imported elements are used for key components, such as the hydraulic main control valve, balance valve, etc. Imported sealing elements are used for the sealing of central rotary joints, hydraulic cylinders and other key components; hydraulic hard pipes are made of high-precision galvanized seamless steel pipes; the system is safe and reliable with smooth movement and good fretting.

The outrigger jack cylinder of the hydraulic system is equipped with the hydraulic lock and each elevating cylinder is equipped with the balance valve, ensuring that the locking of each cylinder in the hydraulic system is reliable and the boom & outrigger are not retracted in any condition (sudden power odd or hydraulic system fault). Turntable swing is equipped with a rotary buffering valve, which is stable in starting and reliable in brake. The hydraulic system is equipped with the maximum pressure control valve, which can effectively prevent the system pressure overload.

The power of the hydraulic system is driven by power take-off at the chassis side. In addition, a standby power source is set up, which is driven by a gasoline engine. The standby power can realize all vehicle movements when the vehicle is retracted. A drain ball valve is installed in a hydraulic oil box, which beings convenience and high speed for hydraulic oil check and replacement.

 

Safety Control System

The unique safety device and control system ensure that the safety and reliability of the vehicle in firefighting and rescue operations. The safety device of the vehicle is composed of electrical control system and hydraulic control system, and plays a role of double insurance. When the electrical control system fails, the hydraulic control system can still ensure the normal use of the ladder assembly in the safe area. The truck’s safety control devices are as follows:

1)      Work range limit: Trucks determine radius limit according to different elevating angles to ensure that the trucks always work within safe ranges.

2)      Soft leg control: In the operation process, if one outrigger does not bear suppression, sound and light alarm signals are reported and the boom cannot go towards a dangerous direction and can go a safe direction.

3)      Upper and lower interlock devices: When the chassis outrigger is not firmly supported or the chassis leveled, the superstructure cannot perform any operation before leveling the car body. When the cantilever crane is not retracted inside the bracket, the vehicle cannot perform any movements.

4)      Deceleration stop device for luffing and extending to limit position of cantilever crane is equipped. When the vehicle boom reaches the elevating angle and is fully retracted or extended, the action speed decreases automatically, and the action stops automatically when the extreme value is reached.

5)      Ladder meso-position drop protection device: When the ladder and platform are close to the tank or cab on the side or above, the boom can fall on the support when the ladder is positioned.

6)      Platform anti-collision protection: The front and the bottom of the platform have ultrasonic anti-collision device equipped. When the platform approaches the obstacle, the device will automatically stop the platform and all boom actions towards the unsafe direction; the screen will display the corresponding icon and text prompt.

7)      Overload control of working platform: When the load on the work platform is overweight, the corresponding icon and text prompt will appear on the screen. At the same time, an alarm is reported. At this time, workload on the platform should be reduced.

8)      Cab protection control: When the boom is within 60° on the left and right of the cab and with an elevation of less than 10°, the boom actions should be limited to avoid damage caused by collision between the boom or working platform and the cab. Corresponding icons and text prompts will appear on the screen, and an alarm will be reported at the same time.

9)      Working platform anti-rollover protection: In any condition, if the inclination between the working platform and the horizontal plane is above 10°, operations will automatically stop and the engine will stop.

10)   Wind speed monitoring and protection: An anemograph is installed to monitor the wind speed. Once the wind speed exceeds a specified value, the ladder assembly lifting and extending will stop and an alarm is reported.

11)   Telescopic protection device: When the aerial ladder extends or retracts to a limit position, the limit valve at the limit position will automatically unload to help the aerial ladder to reliably stop at the limit position.
