Sao PauloCapabCorrosion 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, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Sao Paulo.In our daily life today, hydraulic cargo elevators are also increasingly widely used and deeply loved by customers. As a lifting tool, the maintenance of cargo elevators should not be careless. The following editor will introduce the daily maintenance of hydraulic cargo elevators.
Usage: Scissor fork type fixed lifting platforms are mostly used for goods transportation between height differences in production lines, loading and unloading materials, adjusting the working height during workpiece assembly, feeding materials to loading machines at high altitudes, lifting components during assembly of large equipment, matching storage and loading sites with forklift trucks and other transportation vehicles for rapid loading and unloading of goods, vehicle lifting, fixed three-dimensional parking, and other places.
.Before installing the elevator, confirm whether the motor and the elevator are intact, and strictly check whether the dimensions of each part connecting the motor and the elevator match. Here are the dimensions and fit tolerances of the positioning boss, and elevator groove of the motor.
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.
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,Sao PauloElevating cargo elevator factory building, 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 elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
When working in a hot environment, pay attention to heat dissipation.
After the goods are transported, clean the platform.
Sampling inspection.'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.'.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse, and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation Transformation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore,Sao Paulo8-meter cargo elevator, the platform is level with the ground, without occupying ground space and affecting passage passage.
Connect the motor to the elevator naturally. During connection,Sao PauloChain guide rail lifting cargo elevator, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
For more, please check.Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes, with a scissors type mechanical mechanism, easy to maintain, strong stability, and high bearing capacity. The lifting height is about 10 meters and the load capacity is about 10 tons.
Drain and discard the hydraulic oil from the hydraulic lifting cargo elevator. For the outdoor guide rail elevator, tighten the joint and remove the oil filter. After cleaning, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
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.
Sao Paulo.The water cooling of hydraulic stations is generally tubular water cooling and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the type selection calculation is performed when the flow can be satisfied. Therefore, the two types of cooling are different, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
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.
Secondly, there should be no dirt on the friction surface. If there is any dirt, gearbox, external meshing gear, and other parts of the equipment, as well as the hydraulic oil, must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.
