Unscrew the screw on the dust-proof hole outside the flange of the elevator, adjust the PCS system ring to align the side hole with the dust-proof hole, and tighten the inner hexagon. After that, remove the motor shaft key.It is strictly forbidden for personnel to take the freight elevator to go up and down floors and climb.Pearl,PearlElevating cargo elevator,The series of standards related to mobile elevators. This series of standards is based on the Ministry of Construction's Jianbiao No. document and [] No. document of the Ministry of Construction's product standards. Standards, this series of standards refers to the American ANSIA- 'boom-type elevating work platform' standard and the American ANSI-A- 'self-propelled aerial work platform' standard, and also refers to relevant European industry standards. The standard was reviewed by relevant Chinese departments on January , . The review opinion is: the series of standards for aerial work platforms are comprehensive in content, strong in support and sufficient in basis,PearlDouble guide rail cargo elevator, reflecting the advanced nature and scientific nature of the standards, and the main performance indicators have reached the international advanced level. The standard was published on /.The parts such as reduction box, gearbox, external gear and hydraulic oil are all in accordance with the requirements in the table.Lisakovsk,The motor connection is wrong. When the delta connection motor is wrongly connected into a star shape, the motor still runs with full load, and the current flowing through the stator winding will exceed the rated current, and even cause the motor to stop by itself. If it overheats, it will burn out. When the star-connected motor is wrongly connected into a triangle, or the motor with several coil groups connected in series to form a branch circuit is connected in parallel with two branches, it will cause the winding and core to overheat, and in severe cases, the winding will be burned.The safety device of the guide rail hydraulic lifting platform The mechanical part of the guide rail hydraulic lifting platform mainly includes the hydraulic system and the mechanical device.The wrong connection of the motor of the elevator When a coil, coil group or one-phase winding is reversed, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.

The wrong connection of the motor of the elevator When a coil, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.Loose fixing screws of the motor: The motor fan itself makes a sound when it turns. If the screws fixing the motor are loose, coupled with its own vibration, the motor collides with other parts in a way so it makes a sound; the joints of the pin shafts are dry, lack of oil, iron The rigid friction between the parts and the iron parts will not only damage the parts but also produce abnormal noises so I still want to emphasize again, pay attention to timely maintenance and frequent refueling; if the hydraulic lifting platform does not rise, there is air in the hydraulic oil, you can open it to exhaust If the hydraulic oil is solidified: just replace the hydraulic oil; oil leakage: check whether there is oil leakage at the joints of each oil pipe, if there is oil leakage, replace it in time; reverse the motor: check whether the wiring is wrong; (no Those who understand electricity, and the cost is not high. It is both affordable and safe, and can effectively prevent electric shock.Quality assurance,Regular maintenance Regularly check whether the circuit system of the hydraulic lifting platform is loose, and check whether the wires and cables are aging and damaged, which may cause leakage of the line. If there is, it should be repaired in time to avoid electric shock.If the motor of the hydraulic lift is overheated, stop the machine in time and continue running after troubleshooting. The motor bearings must be in good condition.The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, which increases the copper loss of the winding, causing the winding to overheat and even burn out.

The use of elevators is not to maintain and overhaul after the equipment fails. It is necessary to maintain the equipment according to the correct maintenance and overhaul, and start with the preparation work to prevent all possible failures and accidents. I hope that the editor can summarize the knowledge points today. Help everyone.build,The boxes and distribution boxes of the hydraulic lift are always kept clean, and the dust on the electrical equipment is cleaned in time.Advantages of operating cost: Low failure rate, due to the use of advanced hydraulic system and good methods, the failure rate of elevator operation can be reduced to a minimum. Less power consumption: When the hydraulic elevator goes down, which greatly saves energy.The boxes and distribution boxes of the hydraulic lift are always kept clean,PearlProfessional cargo elevator, and the dust on the electrical equipment is cleaned in time.Pearl,In addition, during installation, it is strictly forbidden to use hammers, etc. to prevent damage to bearings or gears due to excessive axial force or radial force. Be sure to tighten the mounting bolts before tightening the force bolts. Before installation, clean the anti-rust oil on the motor input shaft, the positioning boss and the connection parts of the elevator with gasoline or zinc and sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.Mechanisms: Mechanisms such as tabletops, track grooves, wire ropes, chains and pulleys are made of solid materials to ensure safety.The design of the hydraulic lifting platform is unreasonable. When the designer designs the cylinder barrel and rod, if there is a problem with the design size and angle, then there will definitely be problems in the later stage. Therefore, it is necessary to confirm the technical strength of the manufacturer when working on a hydraulic lifting platform; what is the problem with the sound of the oil cylinder of the hydraulic lifting platform? Design drawings to make, the angle of the oil cylinder is slightly deviated, it will cause the friction between the cylinder barrel and the rod, which will cause the sound; the seal quality of the hydraulic lifting platform is different, and the use of different seals will also affect the sound of the oil cylinder, and the seal with excellent material The continuous friction between the parts and the cylinder wall will cause the sound to be very loud, and long-term wear and tear may scratch the oil cylinder and cause oil leakage, so when the hydraulic lifting platform is used, pay attention to ask the manufacturer what brand and material the seal is used; In some cases of mechanical running-in, and there will still be noises. If there is no problem after investigation, then don’t worry. It’s just a running-in problem between mechanical parts. It will disappear naturally.
