HowardSelf proInstalling bearings for elevators may seem simple, but it is also important to pay attention to some details, sometimes, some people may think of using a hammer to hammer the bearings for convenience, and use brute force during installation. In fact, directly hitting the bearings with a hammer can cause significant damage to the bearings, which is the main reason for bearing damage and reducing the service life of the bearings. So when installing bearings, we must not go too far. Fortunately, and uneven damage to the inner sealing ring or obstacles inside can easily cause uneven stress, resulting in uneven lifting height of the oil cylinder. It is recommended to carefully check whether the oil cylinder is normal.
Howard.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 equipment, and it is strictly prohibited for equipment to be taken out of warranty or repair.
The boxes and distribution boxes of hydraulic elevators should be kept clean regularly, and dust on electrical equipment should be promptly cleaned.
.It is strictly prohibited to connect the motor of the lifting platform to the wrong power supply. It should be ensured that the voltage is 380V or 220V, and daily cleaning work should be carried out. Dust and debris on the motor should be cleaned in a timely manner.
The boxes and distribution boxes of hydraulic elevators should be kept clean regularly, and dust on electrical equipment should be promptly cleaned.
The explanation mainly focuses on the mechanism of lifting platforms and now there are many different types of lifting platforms. In order to better use lifting platforms, we have started to develop different industries using different lifting platforms. Electric lifting platforms have become the main product of small lifting platforms. They are small in size, light in weight, practical in appearance, easy to move, stable and free in lifting, large in load capacity, and large in plane area, Stability has become a machinery that many customers are competing for, and lifting equipment is used in enterprises of all sizes, so the use of lifting platforms is necessary.
The contact opening and closing of the travel switch of each safety device must be reliable, and the contact crater should be polished in a timely manner.
What kind of function can be achieved by installing the elevator? Before installation, confirm whether the motor and elevator are intact,HowardTwo ton hydraulic lifting platform, 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.
Do not adjust the solenoid valve on the motor arbitrarily. The solenoid valve is pre adjusted before leaving the factory and random adjustment can easily cause internal pressure to increase or decrease. In severe cases, it can shorten the service life of the motor.
Customer first.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the size of the oil cylinder, the faster the lifting speed.

Remove and disassemble the hydraulic lift cargo elevator lowering valve, blow out the plunger with compressed air, then install it and reinstall it.
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, a track 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, 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.
device management.Although lifting cargo elevators have good safety, accidents may occur. Therefore if we do not pay attention to detailed maintenance, we should pay attention to them when performing daily maintenance.
Secondly, there should be no dirt on the friction surface. If there is any dirt, it needs to be washed off with gasoline or thinner; The reduction gearbox, 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; The correct maintenance method for hydraulic guide rail elevators is to regularly check the steel wire ropes in various parts for any breakage or looseness. If this phenomenon is found, it should be replaced in a timely manner. The maintenance of the steel wire ropes must be strictly carried out in accordance with the specifications; Check the connection status of each part according to the braking regulations. If there is any looseness, check the normal operation of each mechanism, whether there is noise or malfunction, and promptly eliminate all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to ensure that the centerline of the reducer and gear is parallel and the meshing clearance is appropriate; Regularly conduct a comprehensive inspection of the equipment to check if there is any damage to the wires and cables, and if there is any overheating of the motor. Replace and eliminate the fault in a timely manner before continuing operation; Ensure the bearings of the motor, each box, distribution box, and electrical
Remove and disassemble the lowering valve, blow the valve core clean with compressed air, and then reinstall it.

The inconsistent rotation axis of the support rod in the middle of the hydraulic lifting platform results in the lifting platform being unable to function properly, and was put into the market, causing many accidents. For small enterprises, they are not very concerned about this aspect of tilt detection, This is also why there are such a large number of lifting equipment with this problem. The problems with the oil cylinder and power unit system are often due to insufficient power and substandard oil cylinder quality, which are also very important issues for enterprises themselves.
Loosening: The motor fan makes a sound when it rotates. If the screws that fix the motor are loose, the motor collides with other components,HowardFoot hydraulic lifting platform vehicle, resulting in a sound; The joints of each pin shaft are dry,HowardElectric fixed hydraulic lifting platform, lacking oil, and there is hard friction between the iron parts, which not only damages the components but also produces abnormal noises. Therefore, the editor should emphasize again that timely maintenance and frequent refueling are important; If the hydraulic lifting platform does not rise, there is air in the hydraulic oil. You can open the exhaust hole, add gas and then tighten it again; Hydraulic oil solidification: replace the hydraulic oil; Oil leakage: Check if there is any oil leakage at the interfaces of each oil pipe. If there is any oil leakage, replace it in a timely manner; Motor reversal: Check for wiring errors; (Manufacturers of hydraulic lifting platforms who do not understand electricity in a timely manner)
