Is it enough for ten national standard wire cranes with more than 400 pounds of air conditioners?

There is no standard for the installation height of the outdoor unit. Because the working mode of the outdoor unit will not change, regardless of the high or low, it will be cycled by the compressor to compress the refrigerant. As for the "most of the outdoor units you see, they are lower than the indoors", it is estimated that it is because most of the houses you see are commercial houses or unit houses, and if you install them, they will be installed in other people's homes!

If the outdoor unit is installed up, of course, it can, the condensate discharge is very easy to solve, and the condensate discharge pipe can be separated from the indoor and outdoor unit connection pipe after the hole in the wall, and the condensate discharge pipe will naturally sag a few ok!

This is related to the material of the screw, as long as it is not an aluminum screw or a plastic screw, the general carbon steel screw can withstand this load.

This depends on the specifications, such as:

Thru-wire boom meters).

Thru-wire boom meters).

Thru-wire boom meters).

The theory of the through-wire boom is a long through-body engraved wire bolt; Through the silk, that is, the whole body is engraved. The position of the nut can be adjusted freely. The boom is a hanging screw, and if it is used horizontally, it can become a tie rod.

The English name of the wire boom is bookerrod, also known as the whole wire boom.

The Chinese name is the wire boom, also known as the whole wire boom.

The foreign name is booker rod, which means that the height of the object to be lifted can be adjusted freely.

The formula for calculating the weight of the thread rolling screw per meter = the square of the diameter centimeter, which can be calculated for all specifications.

Specifically, it depends on whether the thread part of the thread is turned or rubbed, and what kind of processing method is used. Turning should consider the turning part, which is related to the pitch, thread bottom diameter, with the weight of the raw material minus the weight of the turning process, if it is rubbed out, the weight is the weight of the raw material.

The thread cross-sectional area of m12 is millimeters squared, then the weight per meter is: centimeters square; The length is 100 cm;

The specific gravity is grams of cubic centimeters, so its weight is:

According to the national standard and non-standard standards to distinguish, but also according to the weight of the wire screw, the same diameter of the wire screw has several weight levels, ** is not the same, I hope to help you, thank you.

12 wire screws have national standard non-standard only, different weights are different, raw materials are produced with new materials and the weight of old materials are also different.

The density of copper is: 8900 kg cubic meters.

kilogram meters. kilogram meters.

A: The weight of copper wire with a diameter of 10 per meter is kilograms.

There is no national standard for coiled steel pipes, I have a longitudinal seam coil welded steel pipe size table here, the pipe diameter of 400mm, the outer diameter is 426mm, and the wall thickness from 6mm to 14mm has to be produced, and the final explanation.

It is written like this, and the material and wall thickness are determined by the design as needed.

According to the theoretical weight table, the steel bar is 10 kg m, which is 9 meters*

That's about 11 pounds.

Now the steel bar ** is 1800 2000 yuan a ton, you can't buy this, unless you go out, such as spending dozens of yuan to buy a ten-meter one. Now the diameter of the steel bar is below 10 (inclusive), all of which are disc steel, and the steel bar needs to be straightened with a straightening machine to be used when used, which is very troublesome. It is still recommended that you buy 12, which saves trouble and the money is about the same.
