Staying below high-altitude work sites is prohibited, and safety nets or other protective devices should be installed below the work site to avoid injury from falling objects.The lifting force of the scarifier is not strong or the lifting force is weak: the pressure regulation of the overflow valve does not meet the need to adjust the pressure to the required value; Refer to cleaning item above for leakage in the oil cylinder; The directional valve is stuck or leaking internally; The oil level is too low, and the oil inlet filter is blocked; The fuel supply pump has drawbacks; Check the wear and tear of the one-way valve core and valve seat, and check if the one-way valve spring is tired or deformed.Shanghai,Loose or leaking connection between the oil suction pipe and the gear pump; The solution is to tighten the suction pipe.Improper use of oil: Inadequate maintenance of high-altitude work platform equipment such as mobile elevators can also lead to small fitting gaps of components, making it difficult for oil to form a uniform oil film on the friction surface. Additionally,ShanghaiHydraulic lifting platform, due to assembly and other reasons, it is difficult to ensure the uniformity of fitting gaps thereby reducing efficiency and causing early abnormal wear of equipment components; In severe cases, it may cause scratches or bite on the friction surface of precision fitting, leading to the occurrence of abnormal equipment noise.Maimanah ,The concept of hydraulic boarding bridge is the power system of the boarding bridge. The large oil cylinder lifts the entire equipment inclined plate. When it is raised to a large height, the small oil cylinder begins to operate, extending the hinge tongue plate. All equipment plates are made of high-quality high height patterned steel plates and profiles, which are lightweight and flexible in movement,When using, the four legs should be firmly supported on a solid ground (based on the walking wheel about to leave the ground), and sleepers can be used when necessary.
In our daily life, hydraulic cargo elevators are increasingly widely used and loved by customers. As a lifting tool, the maintenance of hydraulic cargo elevators should not be careless. Below,Shanghai6-meter hydraulic lifting platform, the editor will introduce the daily maintenance of hydraulic cargo elevators.What kind of function can be achieved by installing the elevator? Before installation, confirm whether the motor and elevator are intact, and strictly check whether the dimensions of each part connected to the motor and elevator match. Here are the dimensions and fit tolerances of the positioning boss, input shaft, and elevator groove of the motor.The main structure and purpose of a guide rail elevator: The mechanical part of a guide rail elevator mainly includes three parts: a lifting device, and a belt changing device. The lifting device is mainly used to suspend the person being lifted, which is the core part of the entire mechanism. The track device is mainly used to provide movement trajectory, making operation more smooth. The belt changing device is used to switch tracks when the elevator is about to pass through a door. The internal structure of the lifting device is mainly composed of gear mechanism, bracket, worm gear,ShanghaiPlatform hydraulic lifting, guide mechanism, lifting arm, upper and lower shells, etc. The gear mechanism mainly includes large and small gears, winding pulleys, central shafts and safety devices composed of stop buckles and torsion springs.Quality inspection report,Use a heavy crane to lift the cage and lift it from above the standard sectionAluminum alloy elevators, also known as aluminum alloy lifting platforms, currently have a wide variety in the Chinese market. They are highly favored by users due to their flexible movement, light weight, and small size.What are the installation precautions for elevators? The folding fence and cage of the elevator should be cleaned of the foundation surface and the foundation bolts should be installed properly. If the construction elevator is installed on the floor, a pad iron must be used below the screws to increase the force surface between the nuts and the floor to reduce the impact of the nuts on the floor; Insert steel plate shims of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite to ensure the verticality of each main pipe in both directions. After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and tighten the remaining anchor bolts; Install the buffer spring; Connect the other half of the fence to the front half with bolts; Adjust the verticality and tighten the anchor bolts as above, and release the brake on the motor inside the suspension cage. (For SC/ models, first install the suspension cage before installing the drive plate).
The pressure of the lifting platform is very important. When lifting goods, the pressure of the lifting platform will test the weight of the goods. If it is overloaded, the general lifting platform will prompt, which serves as protection. Therefore, now lifting platforms are equipped with pressure gauges. Hydraulic machinery should remind everyone to pay attention to the following points: the precautions for using small lifting platforms are based on pressure. Their load-bearing capacity is very poor and their size is small. When using the lifting platform, it will cause structural damage to the lifting platform. We have mentioned this many times before when using it.Potential development,Each box, distribution box etc. is usually kept clean, and dust on electrical equipment should be quickly swept away.Any machinery needs to be maintained after use, let alone large machinery. Poor maintenance of elevators after use can reduce the lifespan of elevators. Today, the editor will tell you how to maintain elevators after use. In order to maintain the good technical condition of elevator machinery, ensure the safe use of on-site construction machinery, extend the service life of equipment, and reduce mechanical failures, construction enterprises must maintain according to the relevant regulations According to maintenance regulations, necessary equipment maintenance work should be carried out. It is not allowed to focus solely on the use and maintenance of the equipment. It is strictly prohibited for equipment to be taken out of warranty or repair.The power unit adjustment, whether it is a scissor type lifting platform or a guide rail type lifting cargo elevator, is composed of the power unit and the oil cylinder. The power unit has four outlets during production, which can be adjusted to increase or decrease the hydraulic oil flow rate of the oil cylinder. We can adjust the motor speed or the electro-hydraulic proportional valve to adjust the hydraulic oil flow rate; What factors will affect the lifting speed of hydraulic elevators? The longer the hydraulic oil pipe, the longer the lifting time. Therefore, during installation, the length of the oil pipe should be minimized as much as possible within the allowable range of the design; On the basis of adjusting the power unit, the size of the oil pipeline can also be adjusted, and corresponding adjustments can be made while ensuring that the equipment meets normal demand and safety.Shanghai,Familiarity with the usage process and without a doubt, this is the first thing to understand. There are two ways to understand it: first, carefully read the user manual provided by the manufacturer when the hydraulic lifting platform leaves the factory; The second is the equipment that needs to be installed. A professional installation technician will be dispatched to install the hydraulic lifting platform. After the installation is completed, relevant users will be trained on the operating process and safety precautions of the hydraulic lifting platform, and some maintenance matters in the future will also be explained; What should be paid attention to during the running-in period when using hydraulic lifting platforms? Check the wear of components. For newly processed and assembled components, there may be subtle deviations in shape and size that require a period of time for running-in. Therefore, during the running-in period, it is necessary to pay attention to whether there is any rapid wear. If there is any, the manufacturer of the hydraulic lifting platform should handle it in a timely manner to avoid equipment failure; Work between the pins and bearings to ensure that they are not worn, and add some engine oil or grease appropriately; Confirm if there is any noise during the running-in period. If it is found that the hydraulic lifting platform is noisy during operation, there is no need to worry in the early stage. If there are no major problems, run it several times more. After the running-in, the noise will naturally disappear. However, if there is noise for a long time and no signs of fading please make sure to promptly produce it and solve the problem; Regularly check if the components are loose. Before use, check if there are any signs of looseness in screws, nuts, oil pipe joints, etc. If there are any, the equipment surface is rough, the area is small, and the load bearing is uneven, which can cause equipment wear. During the operation of high-altitude work platform equipment such as mobile elevators, the concave and convex parts on the surface of the parts are embedded and friction with each other, which will accelerate the wear and tear of the surface of the equipment parts. Therefore, mobile elevators and other high-altitude work platform equipment are prone to wear and tear of components during the running-in period, with a fast wear rate.Unique design; Work; The steel frame can withstand average pressure, effectively reducing the torsion of the frame, and has stronger durability.
