How to maintain the elevator in winter is also the primary reason. Many workers in other industries do not know that the hydraulic oil for hydraulic elevators is also used in different types in summer and winter. Often at low temperatures， the hydraulic oil used in summer will become viscous， or even freeze. After entering the low temperature in winter， be sure to replace the hydraulic oil containing antifreeze in winter， which is suitable for operation at low temperature.
2How to properly handle the elevator after water ingress to keep the elevator high in front and low in back as far as possible， which is beneficial to discharge the water entering the exhaust pipe and avoid damage to the converter.
xHoustonThe secret to ensure the sound operation of the hydraulic system of the hydraulic lifting platform is very simple. It is to ensure its cleanness. Dirt and other impurities shall be prevented from entering the system. Even tiny particles can scratch the valve，Products thus causing costly maintenance.
Just like the failure of the traveling part of the lifting platform，KkradFactory use elevatorsCapable of completely isolating radioactive substances the operator must master the common sense of equipment maintenance failure， so that when the failure occurs， it will not appear too flustered. Generally speaking， the common faults of the traveling part of the lifting platform are divided into:; The bearing bush is burnt， the axle box bearing is burnt the traction motor bearing is burnt， the tyre is loose， and the crack is damaged. Lets share the solution with you.
XMiandowabThis fixed lifting equipment can also be used in the warehouse. For example， a certain floor in the warehouse needs to be lifted to send goods or personnel to the designated warehouse location.In addition to the fixed mode， it is a combination of lifting equipment and vehicle-mounted system. Such a lifting equipment is very flexible to move，Products and of course it is better to use. For example， there is such a lifting equipment in the airport， because it can be moved， Then the scope of operation is not limited to a certain place， but can be used wherever lifting operation is required. For example， when installing outdoor advertisements， some advertisements are relatively high. At this time， mobile lifting equipment can be used to send billboards or staff to the designated height for work. This kind of equipment can also be divided into hydraulic lifting and electric lifting according to the driving mode. The so-called hydraulic lifting is to use hydraulic oil to drive to reach the specified height. The electric mode is to lift to a certain height through motor driving or tooth movement. However， the hydraulic lifting platform is more widely used at present.
FaMany times， after the customer has determined the parameters，Products the designer will first consider all aspects of the factors before design， including the size during transportation，KkradFactory use elevatorsCapable of completely isolating radioactive substances to prevent it from being difficult to transport to the customers installation site after being too wide， so during design and manufacturing， it is necessary to consider separate assembly or table split to meet the requirements. At the same time， we should also consider the bearing capacity of the split， design and manufacture on the premise of ensuring the load and stability， and ensure that the equipment can be transported， hoisted and moved easily.
The heavy operating rod mechanism of the operating rod has defects. Check， adjust and replace unqualified parts; Clean the valve; Check the clamping of the hydraulic oil cleanliness valve core (manufacturing，Lift_ Hydraulic elevator_ Hydraulic lift_ Hydraulic lifting platform - lift manufacturer installation and dirt problems)
The main structure and use of the guideway elevator are closed gear transmission. The big and small gears are made of steel， the design is calculated according to the contact fatigue strength of the tooth surface and checked according to the bending fatigue strength of the tooth root. The support bracket is used to fix and support all mechanical parts and some electrical components inside the lifting case. It is mainly welded from side plates， connecting tubes， connecting pieces and other parts. The materials are selected， including the thickness of both sides of the plate. At the same time， in order to reduce the weight of the support， many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio compact structure， small impact load， stable transmission and low noise， and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can lock itself when the motor is powered off during the handling of patients， so the worm gear reducer is selected. The involute worm is made of steel， and its spiral surface is quenched to improve transmission efficiency and wear resistance. The worm gear is made of polyformaldehyde. Plastic worm gear has the advantages of good processing economy， stable transmission， vibration absorption and noise reduction， light weight， wear resistance and self-lubrication， which makes the design of elevator more humanized.
nNo matter what the problem is， if there is an unsolvable problem with the hydraulic lifting platform， it is fast and convenient to contact the manufacturer first for guidance. Please pay attention to safety precautions during maintenance.
KDuring the installation of the guide rail， the conical cap of the screw on one side of the lifting platform contacts with the slope of the conical hole of the positioning block， and the other side forms a certain gap with the slope of the conical hole of the positioning block， so that the axial force when the screw is tightened separates a transverse force， thus fixing the guide rail roller of the lifting platform. Only after the guide rail positioning device is installed properly， the subsequent installation will be much easier and smoother.
YTotal quality managementHow to use the emergency stop of the hydraulic lift is very important in the process of use. In case of special circumstances the emergency stop can be used. Therefore， before use it is necessary to carefully check whether all items are normal and ensure the effectiveness of the braking device.
vWThe equipment operation is very simple. Just press the operation button， and the equipment height adjustment plate will automatically rise; Release the button， the adjusting plate will fall through the dead weight， and the tongue plate can be used after being put on the truck.
The indicator light is on， press the up button， the motor rotates and the lifting table does not rise. Check≥ When the phase power supply contacts， the motor will reverse after the power supply is connected reversely， and only need to correct the power supply.
To ensure the excellent power supply at the installation site， install a separate distribution box. When the distribution box is used， the electric leakage switch must meet the requirements of the construction elevator. If the installed construction elevator is frequency conversion， the leakage switch should be matched with the frequency converter when selecting the leakage switch.
originalkCheck before use Carefully check the grounding wire safety device， buffer spring， dirt and dust， especially the air， fuel and oil filters of the engine should be checked and cleaned according to the specified time to prevent impurities from entering the cylinder and oil channel， so as to accelerate the wear of moving parts. The lift manufacturer suggests to develop some maintenance systems. The regular maintenance system is based on the wear and service life of mechanical parts and the loss law of oil and liquid， and the number of operating hours of machinery as the main basis for determining the maintenance of machinery， which also becomes the planned expected maintenance system.
The lifting table does not lift when the voltage is too low. Check the starter potential when the motor is working with load. Allowable voltage hydraulic range&Turn to arbitrarily change the two phases in the three-phase line.
cHoustonThe solenoid valve on the motor should not be adjusted at will. The solenoid valve is pre-adjusted before leaving the factory. After being adjusted at will， the internal pressure will increase or decrease， and the service life of the motor will be shortened in serious cases.
sHThere will be electric brushes in this machine. The parts where the brushes touch each other must be kept clean. The bearings in the machine also need to be checked regularly， especially the bearings should be added with grease regularly. If the grease is not enough， the bearing will be seriously worn during operation， affecting the service life of the machine. There are all kinds of wires and cables in the machine. After a period of use， it is necessary to check the wires and cables. If the wires and cables are damaged， they should be repaired or replaced. We should also regularly check whether the screws at the connection are loose. If the screws are loose， we should tighten them. Some screws must meet certain torque requirements. In the absence of relevant professional equipment， we can go to the maintenance shop to use professional equipment to tighten the screws. We must make the screws meet the corresponding torque requirements.
