The scope of use of the lifting platform.
7Power unit adjustment time. Whether it is a scissor type elevator or a guide rail type cargo elevator， they are all powered by a power unit and oil cylinders. We can adjust the hydraulic oil flow rate by adjusting the motor speed or the electro-hydraulic proportional valve; If there are requirements for the lifting time of the cargo elevator， it is necessary to check whether the lifting time meets the requirements.
aBologne CountyThe weight of the lifting platform also needs to be estimated and is not blindly determined. If the weight of goods transported by the Dongguan guide rail lifting platform is greater than the rated load capacity of the elevator， it is easy to reduce the load-bearing performance of the elevator.
The door control switch can only be activated when the doors of each floor are fully closed.
GDrashkinWhen the indicator light for the power supply of the elevator is turned on， and the motor rotates but the lifting platform does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Simply replace any two phase lifting circuit.
IcCheck the relative orientation between the cable support wall and the cable guide frame
Check the smooth steel wire rope and various fasteners， if there is excessive wear，Mobile cllimbing it is necessary to replace them
Add some lubricating oil to each part to extend the service life of the bearing.
kOnly when the hydraulic lifting platform cannot start with load，BakersfieldSelf moving lifting platformReliable there are many incorrect operating methods that often increase the burden on the overflow valve of fixed lifting platform manufacturers. For example the relief valve setting can be adjusted. In the normal operation process， when some fixed lifting platforms slow down， it is not advisable for some customers to adjust the factory settings of the equipment themselves in order to accelerate its operation. When there is a change in equipment speed， you should contact the manufacturer of the fixed lifting platform， and the manufacturer of the fixed lifting platform will send a dedicated person to debug or provide guidance over the phone.
UPoor quality hydraulic oil is as transparent as good hydraulic oil at room temperature， and once used or with temperature changes， it will appear black， white wax and solid blocks will also appear.
WEquipment maintenanceWhen an accident occurs during the operation of the lifting stage， please ring the alarm bell and wait for the cargo elevator operator to come and handle it. Do not tap the button or forcibly pry the door or engage in other illegal activities. How to adjust the cargo elevator overflow valve according to regulations? The function of the cargo elevator overflow valve is to protect the hydraulic system from excessive pressure damage. It is generally placed inside the pump station，Mobile cllimbing with an adjustment valve on one side. Simply adjusting the overflow valve can pose certain risks， as if the pressure inside the oil cylinder or tubing is too high， it may cause malfunctions. Below， the experts from Jinan Tianrui Lifting Machinery will analyze when it is correct to operate the overflow valve?
fDRegularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)
Check and repair the electrical circuit and control panel switch components. If there is aging in the circuit， replace it
It seems that there are many things to pay attention to when using hydraulic cargo elevators， and it is necessary to strictly follow the operating procedures. Therefore， before using hydraulic cargo elevators， we must have a clear understanding. Hydraulic lifting cargo elevator product features: Hydraulic lifting cargo elevator is a non scissor fork type hydraulic lifting platform suitable for cargo transmission between two or three floors of industrial buildings， steel structure buildings， restaurants，Mobile cllimbing and restaurants. The low height is -mm， and there is no need for upper lifting points. The installation forms are diverse
Word of mouth recommendationkAdjust and correct various safety doors and mechanical interlocking equipment
YAccording to GB/T-，BakersfieldSelf moving lifting platformReliable when one of the following situations occurs in the curve related to the aging frequency， it can be determined that the area covered by the effective zone of the vibration mode at that frequency has reached the aging effect: the curve rises and flattens; The curve rises， then falls， and then flattens; The resonance frequency of the a-n curve after vibration is lower than that before vibration; The bandwidth of the a-n curve after vibration narrows compared to before vibration; The resonance peak of the a-n curve after vibration exhibits fission phenomenon; The curve flattens out after descent.
During maintenance， filter cap， inspection hole， hydraulic oil pipe， and other parts. When exposing the system oil duct，Lifting platform - elevator - hydraulic lifting platform - elevator manufacturer avoid dust. The disassembled parts must be thoroughly cleaned before opening. When disassembling the hydraulic oil tank filler cap， first remove the soil around the tank cap. After loosening the tank cap， remove any remaining debris from the joint area (do not rinse with water to prevent water from seeping into the tank). Only after confirming cleanliness can the tank cap be opened. When using wiping materials and hammers， choose wiping materials that do not remove fiber impurities and specialized hammers with rubber attached to the striking surface. Hydraulic components and hydraulic hoses should be carefully cleaned， dried with high-pressure air， and then assembled. Choose a well packaged filter element (the inner packaging is damaged， although the filter element is intact it may also be unclean). When changing the oil， clean the filter at the same time. Before installing the filter element， use wiping materials to carefully clean the dirt at the bottom of the filter housing.
pBologne CountyThe longer the hydraulic oil pipe， the longer the rise time. Therefore， during installation， the size of the oil pipeline can also be adjusted， and corresponding adjustments can be made to ensure that the equipment meets normal requirements and safety.
zPEstablish a regular sampling and testing system for inventory oil. To ensure the quality of outbound oil products， it is necessary to regularly sample and test the inventory of oil materials. After testing， unqualified oil products should be promptly disposed of and cannot be used without the consent of relevant technical departments.
Hydraulic elevator hydraulic system search Based on the hydraulic elevator hydraulic system search for hydraulic pump hydraulic faults， when analyzing and troubleshooting the hydraulic system， the main task is to; Grab both ends&# quo& mdash;& Flash; That is， the power source (oil pump) and the actuator (cylinder， electric motor)， followed by; Even in the middle;， The pipelines and components that pass between the power source and the actuator& ldquo; Grab both ends&# quo; When analyzing， it is necessary to determine whether the fault lies in the oil pump， cylinder， and motor themselves& ldquo; Connect to the middle” In addition to paying attention to analyzing whether the fault is caused by the hydraulic components on the connected circuit， special attention should also be paid to figuring out which method the system uses when transitioning from one working state to another， whether the signal is incorrect， and checking each physical object one by one. Attention should be paid to whether there is any mutual interference phenomenon between the main oil circuits and between the main oil circuits， if there is any mutual interference phenomenon， To analyze how to use adjustment errors， etc.
