Reasons for instability in hydraulic lift platforms

Analysis of the Causes of Instability in Hydraulic Lifting Platforms

Those familiar with hydraulic lifting platforms should know that when the hydraulic lift is unstable, from the perspective of on-site use, the smoke package often slips, the lifting position is difficult to perceive, the middle position cannot be found, and there are phenomena such as lifting noise and oil leakage.

On-site inspections mainly show that hydraulic rapid lifting leads to increased failure rates, seriously affecting production efficiency. There are many reasons for unstable lifting, as detailed below:

Regarding hydraulic lifting platform system failures, the speed theory is used to analyze the reasons for the instability of hydraulic lifting:

(1) Composition of the lifting hydraulic circuit, pump overflow valve, directional valve, directional valve (without throttle) and booster cylinder.

(2) Conduct stiffness research on the lifting circuit. The total flow rate entering the hydraulic system, that is, the total single-direction flow rate formula, is the total flow rate passed; the shape and viscosity of the hydraulic oil, and other relevant coefficients.

Based on the analysis, we can easily draw the following conclusions:

When the load remains unchanged, the smaller the throttle valve inlet, the higher the system; conversely, if the valve opening area is larger, it is lower.

When the load remains unchanged, the hardness is good at low speed, and when the load changes, the hourly rate is just right.

(3) Increasing the supply pressure and increasing the effective functional area of the hydraulic cylinder can improve hardness.

In summary, many equipment failures are related to hydraulics. The main cause of hydraulic elevator failures is the unreasonable design of the hydraulic system upgrade and speed regulation circuit. The editor believes that relevant companies should pay attention to this aspect and not wait until an accident occurs to regret it, which would be counterproductive.

So how do we use Hydraulic Lifting Platform it?

1. Before starting, carefully check each component of the hydraulic lifting platform, check whether the screw connections are reliable, whether there are leaks in the hydraulic pipeline components, and whether the wire connection points are loose or damaged.

2. Before lifting the hydraulic lifting platform, place the four corners on the fulcrum, firmly fix the four support legs on a solid ground, adjust the table to be horizontal (only visual inspection), and then start work after checking the normal displacement of all parts.

3. After entering the platform, close the guardrail door, insert the bolts, fasten the safety rope, and the intermediate load (the seat where people stand) should be located as much as possible in the middle of the console.

4, Hydraulic Lifting Platform Lifting: Press "lift" to start the motor and rotating motor, and the oil tank extends the lifting platform; when it rises to the required height, press the motor's "pause", then delay the lifting of the platform, and then work. If you do not press the "stop" key, the platform will rise to the standard degree and switch the stroke, the platform will stop at the standard position, and after completion, press "down", the solenoid valve will be activated, at this time, the platform will descend by its own weight.

5. Overloading of the hydraulic platform is strictly prohibited during operation, and personnel on the platform must not move during lifting and lowering.

6. When towing the hydraulic platform, retract the support legs, lower the platform to a lower position, and strictly prohibit moving the platform at high altitudes.

That's all for today's introduction. Thank you for watching, and see you next time.
