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, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
El Prague.All previous inspections and commissioning have been carried out, and all technical indicators have met the design requirements. When using, and there is no need to adjust the hydraulic and electrical systems.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
.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.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
This fixed lifting device can also be used inside a warehouse, such as lifting a certain layer of the warehouse to transport goods or personnel to a designated warehouse location.
Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore, when purchasing a lifting platform, it is necessary to consider the use range, frequency of work, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
The opening system of the manual hydraulic stacking platform car can be divided into pedal type and manual control type for selection, which is simple and easy to operate. The vehicle model is divided into fixed and mobile forks, and there are multiple options for ordinary legs and straddle legs. Very suitable for warehouse, supermarket retail goods placement, and extraction.
To ensure excellent power supply at the installation site, install a separate distribution box. When using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
Scheme customization.Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox gearbox, and other parts of the equipment external meshing gear, 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,El PragueSimple lifting cargo elevator, 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, 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.
Guide rail elevator (also known as cargo elevator) is a non scissor fork type hydraulic lifting platform, mainly used in industrial buildings, restaurants, restaurants, warehouses, docks, workshops, and other places where vertical cargo handling is required between two or more floors. The low height is particularly suitable for sites that are not suitable for digging pits on site. What issues should we pay attention to in these places where elevators are used?
The hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
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.
Bidding.The hydraulic lifting platform can be divided into four wheeled mobile type, vehicle modified type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
After careful inspection, it was found that there were two main causes: loss of hydraulic pressure, and leakage of hydraulic valves or seals.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, both the windings and the iron core will overheat the motor is mistakenly connected into two branches in parallel, and in severe cases, the windings will be burned.
El Prague.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 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,El PragueGuide rail chain elevator, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
The anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, we can achieve this. At the same time, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
