Winter Protection of Pneumatic Telescopic Mast

It is a very common natural phenomenon that condensation water freezes outdoors in cold areas in winter. Because it is caused by climate change, air humidity, and light and temperature difference between day and night. Today, we will popularize the defrosting method of the pneumatic telescopic mast to solve your troubles and concerns.

Prevention

When the telescopic mast is not in use, a protective sleeve should be added at the top of the mast. The protective sleeve should be longer to cover all the connecting sleeves. Because it can effectively prevent rain, snow, and dust from entering and achieve the effect of preventing icing.

When the pneumatic telescopic mast is used, a protective sleeve can be added to the joint sleeve to prevent snow retention and condensation of moist air. The protective cover is mainly made of felt, cotton wool, and waterproof cloth.

Thaw

When the airlift mast has frozen condensed water in use, the common safe, and reliable defrosting method is mainly to solve the problem by heating with a hair dryer or electric heating belt.

If it is frozen when it is not in use, it must be heated and thawed before use. It is not allowed to use forcibly. Forced use will easily damage the seals, and in serious cases, it will scratch the inner wall of the cylinder barrel and damage the telescopic mast.

If it is not recovered and frozen during use, first heat the bottom section of the cylinder until there is water dripping out of the drain port. Then start to depressurize and lower the lifting mast, and the lowering speed should be as slow as possible. Because it is not known that it is frozen before being retracted, the air pressure in the rod is released. At this time, the rod must be pressurized before being heated to prevent damage to the telescopic mast and load caused by the impact force suddenly falling under the self-weight and load weight of the lifting rod during the heating process. In this way, each section of the cylinder barrel is lowered and retracted.

The anti-freezing and thawing methods for other types of telescopic masts are similar to each other, and the same method can solve the problem.
