Xuedian technology has newly developed an improved pneumatic retractable mast, which is supported to rotate in the opposite direction. The mast includes adjacent retractable sections which can slide between retracting and extending positions relative to each other. Pneumatic retractable mast also provides pneumatic control system which also makes the mast section move between retracting and extending position. It is the mechanical equipment which makes the mast rotate between the general horizontal and vertical position.
The mechanical equipment of the pneumatic retractable mast includes a driving mechanism that can operate independently of the pneumatic control device, and can reliably keep the mast at any angle between the horizontal and vertical positions. The pneumatic retractable mast includes a light source installed on its upper end, which can be operated with the same DC power supply as the pneumatic control system and the equipment used for rotating the mast.

A pneumatic retractable mast is supported to rotate around a horizontal mast axis in the opposite direction. The pneumatic retractable mast includes: several adjacent expansion segments that can slide between the retracting position and the extending position, the device comprises a pneumatic control device for moving the pneumatic retractable mast segment between the retractable position and the extended position, and the device used to make the pneumatic retractable mast rotate in the opposite direction around the pivot axis between the horizontal position and the vertical position, the improvement of which includes:
The above-mentioned device for rotating the pneumatic retractable mast between the horizontal position and the vertical position, the lighting device for lighting and the DC power supply device, the device for rotating the mast includes the driving wheel device, the device used to make the driving wheel device rotate in the opposite direction and the device including the connecting rod device, the connecting rod device connects the driving wheel device with the mast, in order to make the driving wheel device rotate along one of the two opposite directions mentioned above, so as to make the pneumatic retractable mast rotate towards the vertical position, and is used to make the driving wheel device rotate along the other of the two opposite directions mentioned above, so that the pneumatic retractable mast rotates towards the horizontal position, the lighting device used for illumination is installed on one of the adjacent expansion sections, and the DC power device is used to provide power to the pneumatic expansion mast system, including providing power to the lighting device and the device used for rotation.
In terms of working principle and technical characteristics, this kind of mast is equivalent to a multi-section cylinder. When in use, by injecting and discharging air into the cylinder, the rising and falling movements of each cylinder can be realized.
Each section of cylinder is made of high quality aluminum alloy materials. The whole manufacturing process has gone through many technological processes such as extrusion molding, cold drawing, honing, machining, anodic oxidation and so on, and has gone through strict inspection procedures, to ensure the quality of the mast.
If you want to know the structure of the mast, please refer to the mast structure diagram. If you want to know more, please refer to the relevant technical instructions or contact Nanjing Xuedian company. You will find that the advantages of this kind of mast are: simple structure, but precise manufacturing process, so it is convenient to use and stable in performance, and is your ideal product.
The specifications of the mast are determined according to the number of sections, the maximum section od, the initial height and the maximum height. The technical performance of mast of different specifications is different.
Lifting maximum height (unfolded height):1-30M (can be customized according to requirements, common specifications see attached table);
Closing height: 500MM-4000MM (customizable);
Load: the maximum load is 500Kg and the minimum load is 5Kg (refer to the common specification table);
Lifting Time: 2-3 M/min;
Maximum deflection angle: 5 °;
Maximum torsion angle: 45mrad;
Wind resistance level: Level 8 wind energy works normally, level 10 wind does not damage;
The above parameters are all the parameters of the lift rod of the general model of the company.
