For tower crane buyers，It is not just the functionality of the tower crane that is required.，Also the durability and residual value of the tower crane.。In this regard，Potan tower crane with its excellent quality and lasting stability，Became a trusted choice.。

Let's go through the real comparison.，Look, under the huge time span,，The changes these steel behemoths are undergoing。

The pin in the picture above is from Potain.MC320，Year of production is 2007，It's been 16 years.，It can be seen that the pin hole and the pin fit perfectly.，There is no deformation.。Potham's engineering team has done rigorous calculations.，Control tolerance，Structural design for stress reduction，Even for some components, attention should be paid to the control of the distance from the hole to the end face.，So that it is not easy to deform due to fatigue。After 16 years of use, this Potan tower machine，Its steel structure is still largely intact.，Not affected by rust，This is due to the quality paint of the Potan tower machine.，Excellent workmanship and material control。

Another brand of tower crane was on site just 11 years later.，Due to the problems of steel quality and paint process，There has been a lot of rusting.，May seriously affect the safety of the tower crane。Even if the paint is redone.，Changes in the steel structure can also be seen.。

This tower crane of other brands in 2012，The gear is worn，And rust inside，It may also affect the subsequent service life of the equipment.。

There is no deformation of the 2007 Potain equipment slewing gear at the site.，Because it's greased.，It's probably not that obvious.，But you can see the difference in the details.。

Rust is an important problem of tower crane.，Because it will not only reduce the performance of the tower crane.，It also poses a threat to the safety of the operator。This is the special concern of Potan tower crane in the design and manufacture of its steel structure.。The Potan tower crane is treated with a special anti-corrosion coating.，And high quality steel.，Ensure corrosion resistance，Thereby ensuring the durability and stability of the tower crane.。

Rusty steel structure of other brands of tower crane

Let's look at the advantages of the Potan tower from a more practical point of view.。When you're thinking about buying a used tower crane，You should be concerned about its residual value.。Excellent quality and lasting stability of Potan tower crane，Making it a trusted choice.。Whether new or used.，Potan tower machines offer outstanding performance and value。If you are looking for a reliable brand of tower crane，Then the Potan tower machine is undoubtedly a wise choice.。

Time is the best way to test the quality of tower crane.。With the passage of time，The performance of tower crane under various environmental conditions will be more obvious.。For the next 10 and 15 years,，The status of these tower cranes will be affected by the following aspects：

Deformed pin shaft hole of other brands

Wear and aging：Long-term use will lead to different degrees of wear and aging of various parts of the tower crane.，Uch as a wire rope、Pulley、Pin shaft, etc。These worn and aged components may reduce the performance and safety of the tower crane.，Regular inspection and maintenance is required。

Potain provides better materials.，Better workmanship，More professional design，Only to provide a stable, reliable and long-life tower crane products to buyers.。Technological innovation and upgrading：With the development of science and technology，The design and manufacturing technology of tower cranes are also improving.。New materials、The application of process and technology will improve the performance of tower crane.，At the same time, it will bring higher security and reliability.。So，Some old tower cranes may need technical transformation or upgrading to meet new requirements.。

The Value Journey of a Piece of Steel

Potain is committed to providing industry-leading materials and processes，Technologies introduced by many peers in recent years，Potain was used twenty or thirty years ago.。For example, in the 1990s，Poten has developed a remote control system and a variable frequency speed control mechanism.。Every Potam device you buy is a manifestation of extreme technology.，It is also the precipitation of long-term technology.。
Repair and maintenance：Good repair and maintenance is the key to prolong the service life of tower crane。In the course of use，Regular inspection and maintenance shall be carried out.，Replace the parts with severe wear.，Ensure the normal operation of the tower crane。At the same time，The tower crane shall also be maintained regularly.，Uch as lubrication、Cleaning, etc，To reduce component wear，And that operation efficiency is improve。
