If possible, please provide only your telephone number to meet the needs of your local post office. If you are absent and cannot pick up items at your location in time, the post office may ask you to remind (in most cases, the postman will only give notice).
PS: We maintain a high degree of security and confidentiality of our customer's personnel information.
We mainly use EMS Express and Parcel Register Post for transportation. You can track EMS Express and your local post office. You can follow the post office at your local post office. Both require your signature to accept.
If you need a track number, please send us an email or leave us a message
We can also use other express transportation such as: UPS, DHL, FedEx, TNT etc. The cost will be higher. If you need the above services, you should contact us first.
Freight insurance is included in the S&H fee.
In general, EMS Express takes about 3 to 6 days depending on the location in the United States. Parcel post mail faster than EMS Express
If you do not use it at ordinary times, please contact us. We will first check its track number. If it does not work, we will send a paper tracking application to the USPS post office, which will take a few days to get a reply.
Laser rangefinder can effectively prevent the tower from tipping
Technology and the information age have narrowed the distance between people and countries.Nothing seems to hinder the relationship between the two relationships, but it is in production.Distance measurement is still a difficult problem to solve.For example, in the construction industry, tower crane is one of the most commonly used mechanical equipment.
Tower cranes usually have larger lifting capacity, larger working range and higher lifting height.It can realize the longitudinal and lateral transport of materials, and has been widely used in the construction industry.This large mechanical equipment is used in construction.This process does have its irreplaceable role.Help construction projects complete quickly and easily.
Tower crane is a tower crane structure.This type of equipment is very complex and involves high-altitude work, so it is likely that tower cranes will tip over.On the one hand, these accidents will affect the construction progress of the project, and on the other hand, it will bring huge loss of life and property to the country and people.Therefore, in order to ensure safety and minimize the loss of life and property, laser rangefinders are needed.Auxiliary equipment is used for detection and laser ranging is used for distance measurement.The state also has relevant provisions, tower crane equipment must be equipped with qualified testing equipment to pass the inspection.
Both products have their advantages and disadvantages. Although the tower crane has the disadvantage of being easy to tip over in the process of use, its strong bearing capacity still has an irreplaceable position in the construction industry. Is one of the common equipment.All products are found unsuitable in the process of use, and then they are improved to become more suitable products for our use.The same is true of tower cranes.In order to solve the problem of tower crane prone to tip over, adding laser rangefinder and using laser rangefinder to prevent tilt is the most commonly used method to solve this problem, which has been widely used now.The application has been proved to be practical in practice.
What are the advantages of laser golf rangefinder?
As the name suggests, laser golf rangefinder is a primary for the golf course of an auxiliary machine, but because of its excellent advantage function, make it in practice is not only used in the golf course, but for the whole shopping mall.According to the golf rangefinder merchants query flash, laser golf rangefinder in the whole shopping mall has been an excellent sense of customer understanding.Here's a look at the advantages of laser golf rangefinders after all.
The laser golf rangefinder ends the driveless part of the structure, and through the original laser optical planning makes the laser golf rangefinder in maintaining high brightness of parallel transmission light, the end of the laser scanning method is completely different from the driveless part of the structure, and then useful to reduce the operating pressure caused by the drive. In addition, it also conforms to the environmental tolerance standard IP67, and the standard air scavenging component can also be useful to avoid the sensor head front contamination, ending the environmental tolerance planning for a long period of stable operation in various environments.Because the outer aluminum body and the inner optical unit are independent, the outer body can maintain the internal optical unit after absorbing the impact and temperature changes, making it have strong resistance function in any environment.
Golf laser range finders outside side chooses is made by metal alloy technology, can carry on the work in any situation and environment, make it has high speed and high precision two efficient function, and can carry on the red outer side sight equipment, makes the laser can be visible to the naked eye can see, the more beneficial to customers friends to investigate the intuitive approach, reduce unnecessary cognitive mistakes, arrived in extremely efficient targeting.
Because the laser golf rangefinder has a more ambitious environmental tolerance planning, so that it can minimize the use of time to reduce the wear caused by external objects, in the maximum maintenance of the laser golf rangefinder use life. And because of its concise appearance, no messy planning, the end of completely no drive structure, can be useful to avoid the prism and motor due to long-term use of deterioration, significantly reduce maintenance costs.Then make later need not too much maintenance, can be said to have reached the maintenance free stage, more convenient for customers to use friends.
The above three points are the advantages of laser golf rangefinder.Although the laser golf rangefinder structure is attributed to the very simple mechanical equipment, but it has these advantages are similar products in the market can not reach.And with customer friends on the range finder requirements of the continuous progress and range finder experts continue to develop, making the advantages of laser golf range finder more significant.
