SzegedRail cargo elevatorWhat are the key points of spot trading

The daily maintenance of the cargo elevator should be carried out by a professional team (issued by the AQSIQ).

7Generally check whether all wires and cables are damaged. We should quickly bandage and replace the damaged department.

uSzegedThe dragging mechanism is faulty. When the dragged machine has a fault， its rotation is not flexible or it is stuck， it will overload the motor and cause overheating of the motor winding.

The ripper cannot lift 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; See cleaning in item above for leakage in oil cylinder; The reversing valve is jammed or leaking internally; The oil level is too low and the oil inlet filter is blocked; The fuel supply pump has shortcomings; Check the wear of the check valve core and valve seat， and check whether the check valve spring is tired or deformed.

ZJin AnkunThe reason for the slow rise and fall rate of the aluminum alloy lifting platform and the disposal of the equipment and equipment after the purchase and utilization， due to the improper use or aging， and the use of the hydraulic lift to incubate the dirt，Hydraulic lift the sign of the slow rate occurred. After the speed slows down，BayannurMovable elevatorExecutive agency consider the hydraulic oil flow first. The factors affecting the hydraulic oil flow include: hydraulic pipeline， hydraulic valve， hydraulic oil pump， motor speed regulation assembly， etc. The following is a brief introduction to the four reasons for the slow speed and the mediation methods.

BzPay attention to check whether the wire rope of each part has broken wires and loose strands. If it exceeds the relevant regulations it must be renewed immediately. The care and maintenance of wire rope shall be in strict accordance with the regulations.

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.

So exactly how to replace the elevator hydraulic oil is the right way. In winter，Hydraulic lift the weather is cold， and the elevator hydraulic oil is easy to become thicker， so use thinner elevator hydraulic oil; In summer， the weather is relatively hot and the temperature is relatively high. The hydraulic oil of the elevator is easy to become thin， use a filter screen to filter out the impurities in the hydraulic oil and store it for the next replacement in the next year. Summary: The hydraulic oil of the elevator should be replaced regularly when maintaining the elevator.

mMany customers think that the operating power supply of the hydraulic lifting platform is below the safe voltage of V and will not be electrocuted， which is wrong. Normally， it will not be electrocuted， but it will be very dangerous if there is improper operation. So how can we effectively prevent the occurrence of electric shock accidents? Today， Xiaobian will share some safety knowledge with you.

FDuring 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，Hydraulic lift 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，BayannurMovable elevatorExecutive agency the subsequent installation will be much easier and smoother.

LHigh valueThe lifting of the rated speed and rated load of the guideway elevator means that the power of the main machine must be increased and a larger traction machine must be used. Once the power of the main engine increases， the power of the frequency converter must also increase， and the corresponding contactors and power lines must be enlarged.

yUHow 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.

The good thing about aerial work vehicles is that they should not cover their clothes and park outside. In case of windy and rainy weather， the clothes will repeatedly slap the car paint，Lift_ Hydraulic elevator_ Hydraulic lift_ Hydraulic lifting platform - lift manufacturer especially if the car blows sand on the clothes， it will draw many small scratches on the body， because the paint will be black after a long time. In addition， it should be washed with water， and prevent the dust collector of the aerial work vehicle from scratching the sand on the paint surface.

The multi-pillar aluminum alloy lifting platform is widely used in the cleaning and circuit maintenance of the top floor of the airport， high-speed railway station， shopping mall， star hotel and other halls， with high elevation， low dead weight， transmission and other systems， the site should be disassembled and inspected. When the elevator is flooded everyone should pay attention to it. The above points should not be ignored.

vSzegedHow to judge the clean oil quantity of the lift to the hydraulic station? Why cant we wash the lift hydraulic station with water?

bRThe motor of the elevator will be burnt out after water entering. At this time， the power switch should be turned off immediately and the accumulated water in the pit should be cleaned up.

If the pressure of overflow valve is low， readjust the overflow valve. Under % rated load， adjust the oil level to be too low， fill the hydraulic oil with suction oil， filter the blockage， clean the oil suction section of the filter， and check the oil suction pipe and joint; Tighten the connector. Replace the connector if necessary.
