Sand blasting and paint removal method for tower cranes can quickly remove old paint on tower cranes! The tower crane dustless sand blasting machine can quickly remove the old paint on the tower crane, including the old paint coating on the tower crane, and the cement residue can be removed! The renovated tower crane will restore the original metal color, and the surface will be flat without pits and wear marks after repainting! For the renovation efficiency, each manufacturer’s is different!

The main reasons are as follows:,

1. Each customer’s site is different, and whether there are cranes, forklifts and other construction machinery

2. The sand materials used by each customer are different. The coarser the sand, the faster the efficiency is. The finer the sand, the slower the efficiency is! 3. The corrosion degree of tower cranes is different!

It only takes about 30 minutes to renovate a standard section of 2.2 meters!

The tower crane shall be rectified and renovated in 5 steps:

1. The pipe frame, standard section and elevator to be cleaned by tower crane shall be erected and placed.

2. Knock the thick rust block and hard cement block on the steel structure pipe frame of the tower crane with a hammer or other tools.

3. The spray gun of the sand blasting machine shall be aligned with the pipe rack to be cleaned for rust removal, paint removal and cleaning.

4. After rust removal and paint removal, clean the sand particles scattered on the surface with an air gun to make the steel structure surface clean and tidy.

Renovation advantages of tower crane dustless sand blasting machine:

Simple operation —- semi-automatic processing, only one person is required to operate

The retrofitting of the tower crane is fast – it only takes about 30 minutes to retrofit a 2.2m high tower crane

The tower crane is renovated with good effect – there is no dead corner and old paint; a rust stain; Oxide scale; Oil stain; Cement impurities can be cleaned up to restore the natural color of metal

The cost of the tower crane elevator rust removal sandblasting machine is low – ordinary river sand can be used as sandblasting material. When the electricity is used at about 17 degrees an hour to deal with the agglomeration, it takes time and effort, pollutes the surrounding environment, and it is impossible to achieve clean production. By adopting relevant measures and actively managing, we have solved the problem of agglomeration in the warehouse.

The working principle of tower crane for sand blasting, rust removal and paint removal is to use yellow sand, quartz sand, steel sand, steel shot, etc. to impact and cut the workpiece surface to achieve the purpose of rust removal, oxide skin removal, old paint removal and other surface cleaning, so that the workpiece surface can obtain a certain degree of cleanliness and roughness, so that the mechanical performance of the workpiece surface can be improved. Therefore, the adhesion between the workpiece and the coating is increased, the durability of the coating is extended, and the impurities The noise and oxide layer are removed, and the medium surface is roughened to eliminate the residual stress of the workpiece and improve the surface hardness of the substrate.

The tower crane has the advantages of fast dustless speed, good effect and low dustless cost. While dustless, it can also remove burrs and sundries on the surface, which has a certain beautification effect on the surface.
