Introduction of main features

The aerial work vehicle is a combination of many functions, parameters and performance lead domestic products of the same level. Its main features are:

1. The classic continuation of blue plate cars

The aerial work vehicle is a blue plate 30.8 meters, which continues the classic of Ryaat blue plate 23 meters, 25 meters and 27 meters, and is another classic blue plate product built on this basis.

The vehicle has good driving performance, the length is less than 6 meters, and it is a light telescopic arm product that meets the requirements of blue plate.

The car is equipped with a 1.6 meter stainless steel working platform (a 2 meter folding basket can be selected according to customer requirements), which has a large space and good corrosion resistance, making it convenient for customers to use.

The maximum working height of the vehicle can reach 30.8 meters, and the maximum working amplitude can reach 23 meters. The vehicle adopts a zoned operation mode to meet different operational requirements of customers and ensure the safety of customers\’ use.

2. Simple and fashionable appearance, high-end and grand

The product design is mainly guided by light and fast visual orientation. The new boom style adopts the most advanced design concept and manufacturing process in Europe for the arm section. The boom and turntable adopt the external folding polygonal structure, the boom adopts high strength steel, with high safety coefficient, good stiffness and strong stability.

The open design of the car allows for easy maintenance of the chassis. The on-board telescopic system (wire rope system) and special pipeline conveying system are all built-in, which not only makes the appearance of the vehicle neat and beautiful, but also effectively reduces the long-term exposure to sun and rain for the above-mentioned mechanisms, reduces accidental scratches during work, and extends the service life of the vehicle.

The upper and lower structure of the vehicle is full in shape, with a harmonious proportion. The color is mainly engineering yellow, clean and generous. The small stainless steel fence and side protection are used for getting off the vehicle, combined with aluminum alloy platform, making the whole vehicle more high-end, fashionable and atmospheric.

3. Good working performance and large operating area

This vehicle adopts six sections of 14-sided telescopic arms for synchronous extension and contraction. The action is simple, easy to operate, and the action is fast and the operation range is large; the working platform is placed at the back, so that personnel can easily go up and down.

4. Unique and novel boom structure

Compared with other domestic manufacturers of the same class blue plate, we have the following unique features:

(1) The arm frame adopts the original 14-sided bending design and processing technology, especially the bending of the lower channel steel of each section of the arm. After sufficient theoretical analysis and 100,000 fatigue tests, different bending numbers of different arm frames ensure that the deformation of the arm frame is less, the strength is high, the motion stability is good and the safety is high.

(2) The arm frame is made of high strength steel plate to effectively ensure the safety of operation.

5. Reliability and security

(1) The drag chain used in the whole vehicle dedicated pipeline conveying system is imported brand, with high reliability.

(2) During the product development process, methods such as structural safety verification, stability analysis, and reliability testing are employed to ensure that the product\’s performance is stable and reliable within the operational range. Before leaving the factory, in addition to overload testing, dynamic loads at 1.25 times the rated load and static loads at 1.5 times the rated load are also conducted. All critical structural components undergo tens of thousands of fatigue cycles and destructive tests to ensure the safety and reliability of the equipment.

(3) The safety device is complete, including the hydraulic cylinder stopback device, leg stopback device, upper and lower vehicle interlock device, emergency stop device, soft leg protection device, extreme deceleration, emergency manual operation and other safety protection system to ensure the safety of high-altitude work.

(4) The car is fully equipped, including high-grade mudguard, off-car operation box, etc.

(5) All key structural parts are made of low alloy high strength steel welding, with high strength and light weight. After a variety of tests, it is fully verified to ensure the precise matching of structure, electrical and hydraulic components. All main control components and key transmission parts are made of internationally renowned brands, with stable quality and high reliability.

6. Wireless remote control, comfortable and convenient for one-handed operation

Wireless remote control technology ensures that the operator can operate flexibly and conveniently in a narrow working environment, eliminate blind spots, and have a better working vision. In addition, the operator can avoid enduring cold and hot weather, and can complete the operation in an appropriate place; it can be completed with one hand

Complete the active operation.

7. Fast action and can achieve compound action

There are two options for the speed of leg retraction and extension. When the speed is high, the total time of retraction and extension is less than 60 seconds. The boom can be extended and reduced quickly, and the rotary table rotation, boom extension, boom extension and platform rotation can be realized synchronously, which improves the operation efficiency

8. Smooth work

(1) Start and stop with buffer control to reduce the impact of action;

(2) The leg is controlled by the proportional directional valve to control the flow rate;

(3) The balance valve is used to control the start and stop of each action of the arm frame to ensure the stability of the start and stop actions;

(4) Load sensitive proportional valve is adopted to match the flow rate and speed reasonably;

(5) The hinge point is arranged reasonably, the boom amplitude has no sudden pressure change, the pressure changes uniformly, and the action is stable.

9. Good ergonomics to improve safety and comfort

(1) Seats and foot pedals are set up at the rotary table operation place to rotate with the rotary table, so that the staff can operate more comfortably and reduce the fatigue degree of the staff working for a long time.

(2) The color matching of the control box interface of the turntable is in line with human visual sense, which reduces visual fatigue and improves safety and comfort. The operation interface combines graphics and text, which is simple and easy to understand, reduces misoperation, and improves safety and comfort.

(3) The height of the car operation box is in line with the operator\’s operating height habit. The operation box is equipped with a level, and the operation mark is simple and clear.
