[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Example 1

[0066] like Figure 3-4As shown, a car wash machine brush roller position adjustment mechanism that is easy to disassemble includes two vertical plates 2601, a second traveling wheel 2607 installed between the two vertical plates, and a second track made of rectangular tube installed on the tunnel body to cooperate with the second traveling wheel. A guide wheel 2612 for cooperating with the lower side of the second track is also installed between the two vertical plates. Specifically, a positioning plate 2602 is installed between the two vertical plates, and insert plates 2603 for passing through the vertical plates are installed at both ends of the positioning plate. For ease of manufacturing, the insert plates extend inward between the two vertical plates and are bolted to the positioning plate. Both vertical plates are rectangular plates, and there are two sets of positioning plates. The two sets of positioning plates are respectively... Distributed at the top and bottom of the vertical plates, both located at corners, the positioning plates ensure parallelism between the two vertical plates. The corresponding insert plate of the lower positioning plate extends outwards to the outside of the vertical plate and connects to a base plate 2611. The vertical plate has a downward-facing elongated hole that mates with the central shaft of the guide roller. An upward-facing support rod 2615 is mounted on the base plate. The upper end of the support rod connects to the central shaft of the guide roller, and the lower end of the support rod passes downwards through the base plate. For easy adjustment, the lower end of the elongated hole is bent and extends to the side of the vertical plate. The lower end of the support rod is a screw. An adjusting nut is fitted onto the support rod on the upper side of the base plate. Guide rings 2613 are integrally formed on both sides of the guide roller. The outer diameter of the guide rings... The outer diameter is larger than that of guide wheel two. To facilitate the adjustment of the position of guide wheel two, the central shaft of guide wheel two extends to the outside of the vertical plate and is threaded with a positioning nut 2614. Adjusting the position of the positioning nut so that guide wheel two is in the middle position, and then the guide ring is located on both sides of track two, limiting the position between the position adjustment mechanism and track two. By adjusting the nut, guide wheel two can be pushed upward, thereby pressing the traveling wheel two against the upper surface of track two, improving traveling stability. To further improve the guiding effect, side guide wheels 2608 that cooperate with the side wall of track two are installed on the vertical plate. The vertical plate is machined with an opening that cooperates with the side guide wheel. Both the upper and lower ends are connected to the vertical plate via connectors. The connectors include an inner plate 2609, the outer end of which is inserted into an opening. An outer plate 2610 that mates with the inner plate is installed on the outer side of the vertical plate. A baffle plate that mates with the inner wall of the vertical plate is integrally formed on the inner end of the inner plate. The outer plate and the inner plate are detachably connected by bolts. A socket 2620 that mates with the central shaft of the side guide wheel is machined on the inner plate. The socket is directly opposite the vertical plate and is used for fine adjustment of the side guide wheel. The length of the socket is greater than the outer diameter of the central shaft of the side guide wheel. A set screw 2619 is installed on the outer plate. The set screw can push the side guide wheel inward, thereby pressing the side guide wheel against the side wall of the second track.

[0067] A connecting seat for connecting to the vertical brush roller is installed between the lower ends of the two vertical plates. The upper end of the connecting seat is connected to the positioning plate. The connecting seat includes a base plate 1 2616. A support column 2617 is installed between the base plate 1 and the positioning plate. A base plate 2618 is installed on the lower side of the base plate. A support column is also installed between the base plate 2 and the base plate 1. The support column ensures the connection stability between the base plate 1, the base plate 2, and the positioning plate. The central shaft of the vertical brush roller passes upward through the base plate 1 via a bearing. A drive motor for driving the rotation of the central shaft of the vertical brush roller is installed on the base. A walking motor is installed on the outer side of one of the vertical plates via a mounting plate 2606. The walking motor is connected to the walking wheel 2 via a reducer 2604, thereby driving the vertical brush roller to walk along the track 2. The reducer is a dual-output shaft reducer. A transmission sprocket 2605 is installed on the second output shaft of the reducer. When there are two vertical brush rollers on the same side, only one vertical brush roller needs to be installed with a walking motor. The two vertical brush rollers are connected by a transmission sprocket and a chain, enabling synchronous walking.

[0068] To facilitate easy movement of the car wash machine, the entire car wash machine is designed as follows: Figure 1-29As shown, the car wash machine includes a foundation, which includes a frame. A vehicle passage platform 2 is installed on the upper end of the frame. A mounting beam 210 for the car wash mechanism is also installed on the upper end of the frame. Inclined platforms 3 are installed at both ends of the frame. Specifically, the frame includes longitudinal beams 204, and multiple crossbeams 205 are evenly installed on the upper end of the longitudinal beams. Both the longitudinal and crossbeams are made of I-beams and are welded together, resulting in high structural stability. The vehicle passage platform includes a support frame installed between the upper ends of each crossbeam. The support frame includes multiple parallel support ribs 206. The support ribs run along the machine... The frame is arranged along its length, with supporting ribs made of rectangular tubing, resulting in lightweight construction and high structural stability. A platform plate 201 is laid on the upper surface of the support frame. The platform plate includes panels laid between the upper ends of each supporting rib. A drainage outlet 202 is pre-installed in the center of the panel along the length of the frame. Specifically, the panel is formed by splicing multiple steel plates, with anti-slip textures processed on the upper surface. Adjacent panels on both sides of the drainage outlet are sealed with resin adhesive to prevent downward water seepage. Drainage grooves 20 matching the drainage outlets are installed on the frame. 7. The drainage trough is formed by bending galvanized steel sheet with a U-shaped cross-section and sealed end plates at both ends, providing excellent corrosion resistance. The drainage trough is connected to the sewage tank 6. For easy installation, the drainage trough is laid on the upper side of the crossbeam and supported by the crossbeam. Since the spraying occurs at the inlet end of the car wash machine during the washing process, to prevent sewage from flowing out along the platform plate, drainage holes 203 are machined in rows on the panel near the inlet end of the car wash machine. A water outlet trough 208 that matches the drainage holes is installed on the frame. The water outlet trough is located at the drain... On the lower side of the water tank, there is a water outlet 209 for draining water into the outlet tank. The water outlet extends to the side of the car wash machine and is connected to the sewage tank through the outlet tank. To facilitate the installation of the outlet tank, the outlet tank is connected to the support rib via a U-shaped hook. The support rib is machined with insertion holes 211 that mate with the two wings of the U-shaped hook. The upper ends of the two wings of the U-shaped hook are bent to have hooks that mate with the insertion holes. The distance between the two insertion holes is smaller than the distance between the two wings of the U-shaped hook, thereby ensuring that the two wings of the U-shaped hook clamp the outlet tank tightly and prevent shaking.

[0069] The ramp platform includes multiple parallel support plates 301, with connecting beams installed between each support plate. To facilitate the connection between the ramp platform and the vehicle passage platform, a connecting plate 302 is integrally formed on the upper end of the support plate near the frame. The connecting plate has a connection port 303 for connecting with the crossbeam. The ramp platform is hung on the end crossbeam through the connection port, which is convenient for installation. Spot welding is then performed to improve stability. The working surface of the ramp platform is covered with an anti-slip plate, which is made of steel plate with anti-slip texture on the upper surface. A blocking block 305 is welded and fixed to the lower end of the support plate to support the anti-slip plate and prevent it from moving during vehicle passage. To facilitate the fixing of the drainage ditch, a connecting plate near the middle position is provided. A positioning rod 307 is installed to fix the position of the drainage trough. The positioning rod is inserted horizontally into the connecting plate. The two ends of the positioning rod are bent into blocking rods to cooperate with the side of the drainage trough. The end of the blocking rod is bent. By rotating the positioning rod, the end of the blocking rod can be inserted into the drainage trough. The blocking rod is pressed against the side wall of the drainage trough, thereby fixing the drainage trough. At the same time, the corresponding connecting plate abuts against the end of the drainage trough to prevent the drainage trough from moving and to facilitate installation. In order to improve the structural stability of the ramp platform, the connecting beam includes three connecting pipes 306 that pass between each supporting plate. The three connecting pipes are distributed on the three ridges of the triangular prism. The connecting pipes are welded and fixed to the supporting plates. A groove 304 is processed on the lower end face of the supporting plate to improve the connection stability with the ground.

[0070] To treat wastewater and achieve recycling, the wastewater pool is sequentially connected to a wastewater purification device, a circulating water tank 8, and a car wash machine water supply system.

[0071] The wastewater tank is connected to a wastewater purification device via a circulating pump. A floating platform is placed inside the wastewater tank, and the inlet end of the circulating pump's inlet pipe is located inside the floating platform. Since car wash wastewater contains a large amount of silt and oil, the oil floats on the surface while the silt sinks. The bottom of the wastewater tank is sloped, and a sludge collection tank is built at the lowest point of the tank. A sludge pump 606 is installed in the sludge collection tank to periodically remove sludge and prevent accumulation. The floating platform includes an annular airbag 603 made of petroleum-resistant rubber. A support ring 607, made of nylon, is placed on the upper end of the airbag, and a downward-passing airbag is mounted on the support ring. The filter screen 604 is made of steel wire mesh. The upper end of the filter screen is pressed and fixed to the support ring. The inlet end of the inlet pipe of the first circulation pump is located inside the filter screen. To prevent the inlet pipe of the first circulation pump from detaching from the filter screen, a counterweight 608 made of stainless steel is fitted to the inlet end of the inlet pipe of the first circulation pump. The outer edge of the counterweight is pressed against the filter screen. Specifically, the counterweight is inserted into the filter screen with an interference fit. The inner wall of the sewage tank is a cement mortar layer, which can effectively prevent seepage. The upper end of the cement mortar layer is higher than the ground, forming a waterproof ring 602. A cover plate 601 is installed above the waterproof ring to prevent surface water from entering the sewage tank. The outlet trough is connected to the lower end of the sewage tank through a sewage pipe 605.

[0072] The wastewater purification device includes a horizontally installed purification tank 7. The purification tank is welded from steel plates, is cylindrical, has a galvanized inner wall, and is covered with an asbestos insulation layer 713 on the outer wall. The inlet and outlet of the purification tank are located at both ends. Inside the purification tank, from the inlet to the outlet, there are a filter layer, an adsorption layer, and a clear water layer distributed sequentially. Specifically, the inlet of the purification tank is located on the lower side and connected to an inlet pipe 701, and the outlet of the purification tank is located in the middle and connected to an outlet pipe 702. Two inclined perforated plates 708 are installed inside the purification tank, which divide the purification tank into a filter layer 703 and an adsorption layer 704. The clear water layer (705) has a perforated plate between the filtration layer and the adsorption layer, with a filter screen having a mesh size of 2-3 mm. A reverse osmosis (RO) membrane is laid on the perforated plate between the adsorption layer and the clear water layer. This membrane effectively removes dissolved salts, colloids, microorganisms, and organic matter from the water. The filtration layer is filled with quartz sand (706) with a particle size of 5-8 mm, and the adsorption layer is filled with pumice (707) with a particle size of 3-5 mm. Petroleum-degrading bacteria, specifically Bacillus licheniformis, are introduced into both the adsorption and filtration layers to degrade oils. This process, combined with filtration through the quartz sand, effectively removes these pollutants. The filter effectively traps suspended particles in the lower layer, while some grease is adsorbed by the quartz sand and some rises to the upper surface of the liquid. Pumice, also known as pumice or floating rock, gets its name from its numerous pores, low density, and ability to float on water. Pumice is a porous, lightweight, glassy, ​​acidic volcanic rock, similar in composition to rhyolite. It has a rough surface, a particle density of 450 kg / m³, a loose density of approximately 250 kg / m³, a porosity of 71.8-81%, and a water absorption rate of 50-60%. Its porous structure and floating position on the upper surface provide a suitable substrate for petroleum-degrading bacteria, allowing them to concentrate their activity on the upper layers of the liquid. The oil undergoes biochemical decomposition to improve efficiency. Both the filter layer and the adsorption layer are equipped with a feeding port 710 and a discharge port 711, respectively, with the feeding port on top and the discharge port on the bottom, facilitating the replacement of quartz sand and pumice. An overflow port 712 is provided at the top of the clear water layer to overflow when the water is full, preventing excessive water pressure. Since the petroleum-degrading bacteria generate heat during the process of degrading oil, the second insulation layer can keep the water temperature in the purification tank increased, thereby increasing the proliferation rate of the petroleum-degrading bacteria and automatically reaching a balance. Under normal circumstances, hot water is better for car washing than cold water. The introduction of the second insulation layer improves the car washing effect.

[0073] A valve is installed on the second water outlet pipe, which connects to the first water inlet pipe 808 of the circulating water tank. The second water outlet pipe and the first water inlet pipe form a gravity flow pipe, requiring no power input. The circulating water tank includes a tank body welded from galvanized steel plates, with a cover 801 covering the top. Since hot water is more effective for car washing than cold water, and the tank body freezes in winter, rendering the water unusable, a heating device is installed inside the tank to solve this problem. The outer wall of the tank is wrapped with an asbestos insulation layer 807. Specifically, an upward protrusion 810 is molded in the middle of the cover, and a downward-facing outer protective tube 803 is inserted into the protrusion. The lower end of the outer protective tube extends to the lower part of the tank body and is sealed. The outer protective tube is made of galvanized pipe, which is readily available, low in cost, and has high corrosion resistance and thermal conductivity. A valve is installed on the cover at a position corresponding to the outer protective tube. Equipped with a rain cap 804, it prevents water from entering the outer protective tube. To facilitate cleaning of the outer protective tube, a flange is machined at the upper end, allowing the outer protective tube to be detachably suspended on the cover. The protrusion is hemispherical, providing excellent anti-deformation effect. An electric heating element 811 is inserted inside the outer protective tube. For easy installation, the rain cap includes a support tube 812, with a hemispherical cap body 813 welded and fixed to the upper end of the support tube. The upper end of the support tube is inserted into the cap body, providing excellent rain protection. The flange is fitted into the lower end of the support tube with a gap, thus positioning the rain cap. The side wall of the support tube is machined with a cable passage 814 for cable passage, extending to the lower end of the support tube for easy cable threading. Due to the function of the outer protective tube, the electric heating element is protected, and even in winter when it freezes, the electric heating element can be easily replaced.

[0074] A drain pipe 802 is installed at the lower end of the tank for easy cleaning after draining water. An inlet pipe 802 is installed at the upper end of the tank. To prevent the inlet pipe from becoming unusable in winter due to freezing, a preheating device is connected to the inlet pipe. The preheating device includes a flow channel 809 installed below the inlet pipe, extending to connect with the purification tank. The lower side of the gravity flow pipe is located within the flow channel. A water inlet 815 corresponding to the flow channel is machined on the side wall of the tank. A vertical temporary storage cylinder 806 is fixed inside the tank at a position corresponding to the water inlet. A second circulation pump 805 is installed on the tank, and the inlet pipe of the second circulation pump extends to… At the top of the temporary storage cylinder, the outlet pipe of the second circulation pump extends to the inlet of the flow channel. When it freezes in winter, hot water can be poured into the flow channel. The hot water flows along the flow channel and heats and thaws the gravity flow pipe. The water flows into the top of the temporary storage cylinder. To ensure that there is space at the top of the temporary storage cylinder, when not in use, the water volume in the tank needs to be controlled to not exceed the inlet of the inlet pipe of the second circulation pump. Since the bottom of the temporary storage cylinder is frozen, it forms a container with the bottom sealed. Hot water gathers at the top and is pumped to the inlet of the flow channel by the second circulation pump for circulation heating and thawing. At the same time, it is heated and thawed by the electric heating tube.

[0075] The circulating water tank is connected to the car wash water supply system via a booster pump 12. The car wash water supply system includes a high-pressure water tank 13, which is connected to side spray nozzles 18 and top spray nozzles 17 via multiple outlet pipes 14. A solenoid valve 15 and a pressure regulating valve 16 are installed sequentially on each outlet pipe. The pressure regulating valve controls the water pressure to adapt to spraying at different locations. To prevent low-pressure leakage of residual water after the solenoid valve 1 is closed, a one-way valve 19 pointing to the corresponding side spray nozzle or top spray nozzle is installed at the end of the outlet pipe. To ensure spraying effect, both the side spray nozzle and the top spray nozzle include a connecting pipe 21. The connecting pipe is threadedly and sealed to the outlet pipe. A distributor is connected to the sealing connection of the connecting pipe. It contains a distribution chamber 22, which is connected to a connecting pipe. The side wall of the distribution chamber is machined with water spray holes 23 pointing towards the vehicle body. The distribution chamber enables the water spray holes to be connected and ensures that the water head of each water spray hole is the same. The water spray holes of the side nozzles are distributed in a circular area and are scattering in a scattering direction, which can increase the spray area of ​​the side and is used to clean the side of the vehicle body and tires. The water spray holes of the top nozzles are distributed in a long strip area and are scattering in a scattering direction. The guide plates 24 are integrally formed on both sides to ensure that the water is sprayed out in a fan shape, which can increase the spray area of ​​the side and is used to clean the top of the vehicle body. In order to drain the water in the outlet pipe after use, a drain pipe is installed at the end of the outlet pipe, and a valve 20 is installed at the end of the drain pipe.

[0076] To make full use of water resources, the car wash water supply system also includes a well 10 and a rain collection box 28. To reduce the footprint, the rain collection box is installed on top of the car wash machine. The lower end of the rain collection box has a V-shaped cross-section, which allows debris to be concentrated in the middle. A slag discharge port 2805 is machined at the lowest position of the rain collection box. The slag discharge port is opened periodically to discharge slag. To increase the amount of rain collected, two rain collection plates 2803 are installed at the upper end of the rain collection box. The rain collection plates extend outside the rain collection box. For easy installation and cleaning, the rain collection plates are installed on both sides of the rain collection box via hinges 2801. A downward-facing screen plate 2804 is integrally formed at the inner end of the rain collection plate. The water outlet pipe 2803 of the rain collection box is located on both side walls. The screen plate can filter out debris such as leaves, ensuring the cleanliness of the car wash water.

[0077] The booster pump's inlet pipe is connected to a water well, a rainwater collection tank, and a circulating water tank via three water pipes equipped with solenoid valves-15. Under normal conditions, water can be recycled through the circulating water tank, sewage pool, and purification tank. However, due to losses during use and water discharged through the sludge pump, water needs to be replenished. In summer, when it rains, water is mainly replenished through the rainwater collection tank. In winter, when the groundwater temperature is high, water is mainly replenished through the water well to ensure water temperature and improve adaptability. Especially in winter, after use, the water in the circulating water tank is drained, and water is replenished to the circulating water tank through the water well when it is used again, which can reduce the heating and thawing steps.

[0078] The mounting beam is made of I-beams and welded to the top of the longitudinal beam. A car wash mechanism is installed at the upper end of the mounting beam. The car wash mechanism includes a tunnel body 1, which is constructed of steel and enclosed with corrugated steel sheets. A horizontal brush roller 5 and a vertical brush roller 4 are installed at the tunnel body's inlet. The first end of the horizontal brush roller is connected to the tunnel body via a lifting seat. A drive motor for rotating the horizontal brush roller is installed on the lifting seat. A lifting device for raising and lowering the lifting seat is installed on the tunnel body. The second end of the horizontal brush roller is connected to the tunnel body's side wall via a length adjustment device. Specifically, the lifting device is a winch, and the winch's cable is connected to the lifting mechanism. The seat connection and length adjustment device includes two support plates, namely a first support plate 2501 and a second support plate 2502. The first and second support plates are connected by a support rod, the end of which passes through the corresponding first and second support plates. The first support plate is connected to the horizontal brush roller via a bearing 2505. The second support plate is connected to a traveling wheel 2506. A track 2506 matching the traveling wheel 2506 is installed on the side wall of the tunnel body. The track 2506 is a track groove. To facilitate adjustment of the distance between the first and second support plates, both the first and second support plates are rectangular plates. Support rods are installed between the four corners of the first and second support plates. The support rods are threaded rods 2503, and adjusting nuts 2504 are fitted onto them to mate with the corresponding first and second support plates. By adjusting the adjusting nuts 2504, the distance between the two support plates can be adjusted, thereby adjusting the position between the first traveling wheel and the first track, reducing the obstruction of movement caused by deformation of the first track. A guide device is installed at the end of the axle of the first traveling wheel. The guide device includes a groove machined into the end of the axle of the traveling wheel, and ball bearings 2507 machined in the groove to mate with the track. To ensure smooth ball rotation, the bottom of the groove is hemispherical and has an oil groove 2508. The oil groove is filled with grease, which the ball carries out during rolling, thus providing lubrication. The ball prevents the traveling wheel from contacting the bottom of the track, ensuring smooth movement. Both ends of the horizontal brush roller are equipped with pressure rings 501 that tighten the bristles inward, preventing the bristles from splashing water onto the track. For easy connection, a connecting plate is welded to the outer end of the pressure ring, and a connecting ring 502 that mates with the connecting plate is welded to the outer end of the horizontal brush roller's shaft. The connecting plate and the connecting ring are bolted together.

[0079] The upper end of the vertical brush roller is connected to the side wall of the tunnel body via a detachable car wash brush roller position adjustment mechanism. A drying device is installed at the exit end of the tunnel body. The drying device is as follows: Figure 26-29As shown, the air-drying device includes a suspension beam 901 installed at the upper end of the tunnel body. Multiple adjustable fans 905 are mounted on the suspension beam. For ease of adjustment, there are two suspension beams, with multiple crossbars 904 installed between them. The fans are mounted on the crossbars. A positioning device for positioning the crossbars is installed on the suspension beam. An elongated slot 902 is machined on the suspension beam to mate with the crossbars. The end of the crossbar is inserted into the elongated slot. The positioning device includes teeth machined along the sidewall of the elongated slot. A gear 910 is fitted onto the end of the crossbar via a short shaft 907. A gear ring 903 mates with the gear through the end of the short shaft. Extension plates 90 are integrally formed on both sides of the gear ring. 8. The extension plate is machined with a positioning rod 909 that meshes with the gear. The crossbar is made of rectangular tubing. Fan 1 is connected to the crossbar via a U-bolt 906. By disengaging the gear from the gear ring, the crossbar can be moved along the length of the elongated opening, thereby adjusting the lateral position of Fan 1. Loosening the U-bolt allows Fan 1 to be moved along the crossbar, thereby adjusting the longitudinal position of Fan 1. Rotating the crossbar adjusts the angle of the fan. After adjustment, the gear and gear ring are engaged. The meshing of the gear with the positioning rod prevents the lateral movement of the crossbar. The meshing of the positioning rod with the side wall of the elongated opening prevents the crossbar from rotating. Tightening the U-bolt fixes the position of Fan 1, facilitating operation.

[0081] Unlike Example 1, the air-drying device is as follows: Figures 30-34As shown, the drying device includes a contour-following fan, which includes a horizontal air duct 2701. The air duct is welded from galvanized sheet. Two fans 2702 are installed at both ends of the air duct, and the two fans deliver air in opposite directions. A long strip-shaped air outlet is reserved at the lower end of the air duct. The side wall of the air outlet is integrally formed with a guide plate 2704. The included angle between the two guide plates is 10-20° to ensure concentrated airflow. Vertical tracks that cooperate with the air duct are installed on the tunnel body, and the two ends of the air duct are guided by guide devices. Connected to the track, the ventilation duct has a lifting device installed at least at one end between it and the tunnel body. The lifting device includes a winch, and the winch's cable is connected to the end of the ventilation duct. The track includes a vertical web 2711 with connection holes 2707 machined on it for connection with the tunnel body. Wings 2712 are integrally formed on both sides of the web, with an angle of 100-120° between the wing and the web. A reinforcing rib 2713 is installed between the outer side of the wing and the web, and the cross-section of the reinforcing rib is L. The structure features reinforcing ribs arranged along the length of the web. The two wings of the reinforcing ribs are fixed to the web and wing plates, respectively. The guiding device includes a connecting seat 2703 installed at the end of the duct. A guide head 2706, which mates with the track, is mounted on the connecting seat. The guide head includes a vertical connecting plate 2705. A guide seat, which mates with the track, is welded and fixed to the surface of the connecting plate corresponding to the track. A guide wheel 2708, which mates with the wing plate, is mounted on the side wall of the guide seat. An opening, which mates with the guide wheel, is machined on the side wall of the guide seat. A pressure plate 2709, used to fix the end of the central shaft of the guide wheel 2, is also mounted on the guide seat. A positioning opening 2710 is machined at the end of the central shaft of the guide wheel. The pressure plate is pressed into the positioning opening, thereby securing the guide wheel 2. Due to the wide width of the duct and the need for positioning during operation, the cooperation of the guide seat, guide wheel 2, and track ensures the stability of the duct during lifting and lowering, as well as stability during operation.
