NancyConstruct'Using the elevator is not about maintaining and overhauling the equipment after it has failed. It is important to maintain the equipment in accordance with the correct maintenance and overhaul. First, do the preparatory work to eliminate all possible fault problems and accidents. I hope that today's summary of knowledge points by the editor can help everyone.'.
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling,NancyOne ton cargo elevator, and alignment, and ensure the level of the foundation and various usage requirements.
Nancy.Any kind of machine or equipment will undergo a series of inspections and debugging before leaving the factory, until all links are qualified. Take the mobile elevator for example, the same is true. Of course, during the internship, there will still be some questions about the elevator but if there is no contact, just mastering some specific information can effectively handle these questions.
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 working current, causing the winding to overheat or even burn out.
.The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, diesel engine.
For guideway elevators installed outdoors,NancyElevating cargo elevator 1-4 floors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Incorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely, it can 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 working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
3. High pressure water abrasive rust removal. A type of spiral elevator that utilizes the impact of high-pressure water jets and abrasive to polish and remove rust. It has the advantage of causing little damage to the material, but water can cause certain damage to electronic equipment. It is suitable for the detachable type of spiral elevator.
Several types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
technical service.Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks, airports, hotels, posts and telecommunications, municipal gardens, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled walking, electric starting, self supporting legs, large working area, and especially the ability to cross obstacles for aerial work.
Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground, without occupying ground space and affecting passage passage.
In addition to having a fixed mode, there are also types of mobile elevators. As the name implies, it is a combination of lifting equipment and on-board systems. This type of lifting equipment is very flexible to move, and of course, it is better to use it. For example there are such lifting equipment in airports, and stations or stadiums may also be equipped with such equipment, as it can be moved by itself The scope of work is not limited to a certain place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to send billboards or staff to a designated height for work. This type 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 the use of hydraulic oil to drive to achieve a specified height. The electric mode is driven by a motor or tooth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Total quality management.What is the new price of fixed elevators? Fixed elevators are currently very popular in the market. Due to different manufacturers, different materials, different load ratings and different brand awareness, the prices also vary. Currently, the prices of fixed elevators produced in the domestic market are: rated load 1-5 tons, lifting height 7 meters, table size 2500 mm * 2000 mm, and the price is around 27000-45000 yuan; The rated load is 1-3 tons, the lifting height is 0 meters, the table size is 2300 mm * 2000 mm, and the price is around yuan. Rated load and lifting height of each fixed elevator,
The main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates,NancyHydraulic cargo elevator and lifting cargo elevator, connecting tubes, and connecting pieces. The materials are all selected, including the thickness of both sides of the plate, products, and tens of millions of products. Professional elevator factory transactions are safe and guaranteed. At the same time, in order to reduce the weight of the bracket many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, compact structure, small impact load, stable transmission, and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling, so a worm gear reducer is selected. The involute worm is used, and the material is steel. Its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear is made of polyformaldehyde. Plastic worm wheels have the advantages of good processing economy, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.

Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found, go to a professional beauty shop for processing in a timely manner.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
