Firstly, the maintenance process should be carried out on the premise of ensuring the safety of staff. Before repairing the elevator, the power must be disconnected, and the power must be verified and hung up; No power transmission, people working&# quo; Identification plate for. During the maintenance process, it is not allowed to disconnect the grounding wire of the elevator. If it is necessary for maintenance work, after the maintenance is completed, the grounding wire must be connected before the power test can be conducted. When replacing elevator spare parts, it is necessary to ensure that the spare parts are available
The scientific design schemes for elevators mainly include leveling and locking circuits telescopic balance circuits, variable amplitude balance circuits, emergency lowering systems, etc. In order to prevent sudden damage to the hydraulic system or pipelines of the platform due to accidents, we have designed different solutions for each system according to its different conditions.
Luancheng.During the trial load, multiple tests should also be conducted. For the second trial load, an empty load test can be selected to verify whether the lifting and lowering speeds of the elevator are reasonable, whether the stability of the platform meets the requirements, whether the sound is normal, and whether the rated lifting height can be reached. If the test data is normal, a second trial load test can be conducted; The second trial load test can choose half load test, with a focus on verifying the stability of the platform. If the shaking resistance is within the allowable range, the fourth test - overload test can be conducted, and 110% of the load can be added for the test to verify whether the anti overload device setting of the platform is reasonable. If the setting is correct,LuanchengVehicle mounted hydraulic lifting platform, the lifting platform cannot rise under overload. If it can rise, it indicates that the overload device setting of the lifting platform is unreasonable, and the manufacturer should be asked to adjust the setting again.
When repairing the elevator, there are many precautions to pay attention to during the maintenance process. We have summarized the relevant matters for your reference only.
.Compact structure small size in transportation status, able to enter the car of general elevators, as well as smooth door openings and narrow passages.
Multi mast lifting platform: it is refined from high-strength aluminum profiles as a whole. Due to the high strength of profiles and the four mast structure, it has excellent stability, flexible operation, large load capacity, large platform area and convenient implementation. Its appearance allows for high lifting capacity in extremely small spaces. Minimize the deflection of the lifting platform.
Support is an important preparatory work for elevator operation. The elevator should choose a flat ground, such as a foundation or uneven terrain, and must be padded with sleepers before proceeding with work.
The lifting drive chain is a double chain structure, using industrial plate chains with high bearing capacity and safety factor.
A lift is a fixed transportation device that lifts items from one height to another. Due to the large weight and volume of the lifted object it is safe and stable. It can be used as a specialized hydraulic lifting platform product for transporting goods between floors of buildings, with the main function of transporting various work floor goods up and down; At present, elevators in the market are mostly used for three-dimensional garages and garage floor height car lifts. The performance characteristics of elevators are as follows:.
Blow out the plunger with compressed air, the use of stable voltage in elevators is crucial for safe operation. Elevators have high stability, a wide working platform, and a high load-bearing capacity, making high-altitude operations more efficient and safe. To avoid the harm of voltage instability, please ensure voltage stability.
Single group high-strength mast elevator, with light weight and good maneuverability, suitable for single person operation.
What are the advantages of elevators? Many customers, when consulting, do not understand the various types and uses of complete elevators, and are basically blind, thinking that their company lacks a machine that can work at heights. Is it better to use a regular ladder or a lifting platform? But we can firmly tell you that some heights of ordinary ladders are limited, and instability in high altitude can easily lead to accidents. And mobile elevators, with convenient lifting and flexible movement,LuanchengHydraulic lifting cargo elevator, are also rare safety tools. The types of high-altitude work platforms commonly needed by factories or companies are scissor forks and elevators. Today, we will focus on explaining some of the advantages of elevators to you.
The double protection leg structure ensures safer work and can be used for lifting and lowering operations close to the working face.
Welcome calls .At the end of the year, many customers called to inquire about elevators. During this time of year, various units need to hang lanterns, etc. Many customers do not know how to choose a suitable elevator. Below is an answer for everyone. Lifts can be generally divided into three types: manual traction mobile lifting and lowering platforms: This type of lifting platform is cost-effective, cheap, and widely used, When moving, it requires manual traction or mechanical pulling from a car, and when lifting, it requires an external 220V or 380V power supply to lift.
Dangerous parts that move back and forth, such as the hammer body of a forging hammer, the slider of a pressure machine, the blade of a shearing machine,LuanchengDouble cylinder hydraulic lifting platform, and the teeth at the edge of a band saw.
Hydraulic lifting platform products are divided into curved arm hydraulic elevators, scissor fork hydraulic elevators, mast hydraulic elevators, docks, airports, hotels, posts and telecommunications, municipal gardens, cleaning companies, public building facades, or the installation and maintenance of power systems. 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 high-altitude operations.
Luancheng.Single masted elevators are widely used in factories, hotels restaurants, stations, cinemas, exhibition halls, and other places. They are a good safety companion for maintaining equipment, painting and decorating, replacing lighting fixtures, electrical appliances, cleaning and maintenance and other purposes.
The main lifting mast adopts high-strength profiles, which have high safety and light overall weight.
Drain all the hydraulic oil in the oil tank, open the oil tank, take out the oil suction filter, clean it, and return it to the oil tank. Install it in its original position. Fill the fuel tank with new oil.
