There are several ways to install ladders for chimneys
As an important industrial facility, the safety and reliability of the chimney are of paramount importance for industrial production. In the process of chimney maintenance and overhaul, the installation of ladders is an indispensable link. This article will introduce several common methods of chimney installation ladders, in order to provide reference for relevant practitioners.
1. Installation ladder for fixed chimneys.
Fixed chimney installation ladder refers to the construction method of fixed installation of ladder on the cylinder wall or top of the chimney after the construction of the chimney is completed. The advantages of this method are that it is easy to construct and less costly, and it is suitable for chimneys with low height and less frequent maintenance.
The specific steps are as follows:
1.According to the height and diameter of the chimney, design the appropriate ladder size and spacing, and determine the ladder installation position on the chimney cylinder wall.
2.At the ladder installation position, drill holes and insert expansion bolts to fix the fixing parts of the ladder to the chimney barrel wall.
3.According to the design requirements, the beam and tread board of the ladder are installed on the fixings one by one, and adjusted and fixed.
4.Check the installation quality of the ladder to ensure that it is safe and reliable, and complete the installation.

2. Movable chimney installation ladder.
Movable chimney installation ladder refers to the construction method of installing the ladder outside the chimney barrel wall and moving with the lifting of the chimney. The advantage of this method is that it is easy to maintain and overhaul, and it is suitable for chimneys with high height and high frequency of maintenance.
The specific steps are as follows:
1.Slide rails and pulleys are installed on the outside of the chimney barrel wall to support and move the ladder.
2.The beams and tread plates of the ladder are installed on the slide rails and pulleys to ensure that they can be raised and lowered as the slide rails move.
3.A driving device is set inside the chimney barrel wall, and the power is transmitted to the pulley through transmission elements such as chains or wire ropes to drive the ladder to lift.
4.Regularly inspect and maintain the ladder and its transmission elements to ensure that they are safe and reliable.
3. Ladder installation for hoisting chimney.
Hoisting chimney installation ladder refers to the construction method of hoisting the ladder to the top of the chimney as a whole by using hoisting equipment. The advantages of this method are that the construction speed is fast and efficient, and it is suitable for chimneys with high height and difficult construction.
The specific steps are as follows:
1.Brackets and hoisting equipment are set above the chimney for supporting and hoisting the ladder.
2.The ladder is hoisted to the support as a whole and fixed.
3.According to the design requirements, the beams and tread plates of the ladder are installed on the chimney wall.
4.Check the installation quality of the ladder to ensure that it is safe and reliable, and complete the installation.
