The wrong connection of the motor of the elevator When a coil, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, the short-circuit current is much larger than the normal operating current which increases the copper loss of the winding, causing the winding to overheat and even burn out.poland,Check before use Carefully check the grounding wire, safety device, etc. before use. Make sure it has a safe usage environment.Nowadays, small and medium-sized enterprises are holding products with the idea of ​​good quality and favorable price.Brakpan,In addition to the fixed mode the elevator also has a vehicle-mounted mobile type. As the name implies, it combines the lifting equipment with the vehicle-mounted system. Such a lifting equipment is very flexible to move, and of course it is more useful. For example There is this kind of lifting equipment in the airport, and it is also possible to install this kind of equipment in stations or stadiums. Since it can be moved, the scope of operation is not limited to a certain place,polandFixed hydraulic lifting cargo elevator, and it can be used wherever lifting operations are required. It can be used. For example, the height of some advertisements is relatively high. At this time, mobile lifting equipment can be used to send billboards or staff to the designated height to work. This kind of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is driven by hydraulic oil to reach a specified height. The electric mode is driven by a motor or geared to lift to A certain height but at present, hydraulic lifting platforms are more widely used.Mechanisms: Mechanisms such as tabletops, track grooves,polandConstruction site personnel lifting cargo elevator, wire ropes, chains, and pulleys are made of solid materials to ensure safety.It is best not to cover the aerial work vehicle and park the vehicle outside. If it is windy and rainy, the clothing will repeatedly slap the car paint, especially if the car blows sand on the clothes, it will draw many fine scratches on it. Because it will turn black over time. In addition, and prevent the sand particles on the paint surface from being scratched by the vacuum cleaner.

It is strictly forbidden for personnel to take the freight elevator to go up and down floors and climb.It is forbidden to use hemp rope as a safety rope when using a mobile lift for high-altitude operations.The wrong connection of the motor of the elevator When a coil but it should be washed with water, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.Test conclusion, if there is a problem with the design size and angle, then there will definitely be problems in the later stage. Therefore, it is necessary to confirm the technical strength of the manufacturer when working on a hydraulic lifting platform; what is the problem with the sound of the oil cylinder of the hydraulic lifting platform? Design drawings to make, it will cause the friction between the cylinder barrel and the rod, which will cause the sound; the seal quality of the hydraulic lifting platform is different, and the use of different seals will also affect the sound of the oil cylinder, and the seal with excellent material The continuous friction between the parts and the cylinder wall will cause the sound to be very loud, and long-term wear and tear may scratch the oil cylinder and cause oil leakage, so when the hydraulic lifting platform is used, pay attention to ask the manufacturer what brand and material the seal is used; In some cases of mechanical running-in, it is not ruled out that the above three situations are normal, and there will still be noises. If there is no problem after investigation, then don’t worry. It’s just a running-in problem between mechanical parts. It will disappear naturally.The contact opening and closing of the travel switch of each safety device must be reliable, and the contact arc crater should be polished in time.The last thing to note is that, protective fences are generally added on the platforms. Since the lifting platforms are special equipment, the National Quality Inspection Bureau is very strict on this piece of inspection. All must be dismantled, so when the personnel ask you if you want to add a guardrail, don't blindly refuse, and consider whether it is necessary according to the site of use. In addition, you must have the 'People's Republic of Special Equipment Manufacturing License' and the 'People's Republic of Special Equipment Installation, Transformation and Maintenance License' to produce, install, and maintain. Therefore, you must ask whether the manufacturer has these two certificates.

Features of hydraulic lifts: According to the working mode, hydraulic lifting platform products are divided into crank arm hydraulic lifting machines, scissor hydraulic lifting machines, mast type hydraulic lifts, and straight arm hydraulic lifting machines. The hydraulic lift is a replacement product of the folding arm lift (lifting platform) and the scissor lift (lifting platform). It can be widely used in stations, docks, airports, hotels, post and telecommunications, municipal gardens, garages, cleaning companies, public building facade decoration, decoration or installation and maintenance of power systems, etc. The lift has the advantages of light weight, self-propelled, electric start self-supporting legs, simple operation, large working area, especially the ability to cross obstacles for high-altitude operations and the like.Let's see,Mechanisms: Mechanisms such as tabletops, track grooves, wire ropes, chains, and pulleys are made of solid materials to ensure safety.Problems to be considered in the transportation of lifting platforms But in the use of elevators, some relatively large places will purchase lifting platforms that suit their needs according to the requirements of users, which means that the equipment that is too large will exist in the transportation Difficulties, this is also a problem that many users and manufacturers are more worried about. The equipment is large in size and occupies a large area. It is inconvenient to carry it back and forth, and it is very difficult to move. So how should we solve it? Today, the editor will introduce to you in detail how the large lifting platform solves the problem of transportation difficulties.Brake operators of various mechanisms on the equipment should regularly check and adjust the gap between the brake shoe and the brake wheel to ensure flexibility and reliability. Long-term promotion of freight elevator factory, old brand, price advantage,polandChain lifting cargo elevator, quality guaranteed!poland,Features of hydraulic lifts: According to the working mode, scissor hydraulic lifting machines, mast type hydraulic lifts and straight arm hydraulic lifting machines.

When the delta connection motor is wrongly connected into a star shape, the motor still runs with full load, and the current flowing through the stator winding will exceed the rated current, and even cause the motor to stop by itself. If it overheats, it will burn out. When the star-connected motor is wrongly connected into a triangle, or the motor with several coil groups connected in series to form a branch circuit is connected in parallel with two branches, it will cause the winding and core to overheat, and in severe cases, the winding will be burned.
