If you are in the construction industry, you know that tower cranes play a critical role in the success of any building project. Tower cranes are used to lift and move heavy materials and equipment from one location to another. One of the most important components of a tower crane is the mast section. The mast section is the vertical part of the crane that supports the jib and the load. One type of mast section that is commonly used in tower cranes is the L68A1.
The L68A1 mast section is a key component of tower cranes that are used for heavy lifting. It is designed to provide stability and strength to the crane, allowing it to lift heavy loads with ease. The L68A1 mast section is made up of four panels that are assembled using special fishplate bolts. Two of the panels have telescoping lugs, while the other two do not. When assembling the mast section, the panels with ladder-fixing gussets must be face to face. The L68A1 mast section is made of high-quality steel, such as Q345B and Q235B, which gives it the strength and durability needed to withstand the rigors of heavy lifting.
Overview of Mast Section L68A1
If you are looking for a reliable and sturdy mast section for your tower crane, the L68A1 mast section might just be the right choice for you. This mast section is widely used in the construction industry due to its excellent performance and durability.
The L68A1 mast section is made up of four panels, two of which have telescoping lugs and two of which do not. The panels with ladder fixing gussets must always be assembled face to face. The panels are held together by 20 special fishplate bolts, with the heads of the bolts on the outside.
This mast section is designed to be compatible with a variety of tower crane models and can be used for lifting heavy loads with ease. It has a lifting capacity of up to 12 tons and can reach a maximum height of 60 meters.
The L68A1 mast section also comes with a lifting weight limiter, which ensures that the crane does not exceed its maximum lifting capacity. The force measuring ring of the limiter is fixed on the support of the tower crane mechanism, while the other end is fixed on the guide pulley.
Overall, the L68A1 mast section is a reliable and efficient choice for tower crane operators looking for a sturdy and durable mast section that can handle heavy loads with ease.

Once the site has been assessed, the installation team should review the manufacturer’s instructions in full detail. This will provide practical information that is essential for safe and efficient installation. It is important to fully understand the instructions before starting the assembly process.
During the assembly process, it is important to position the auxiliary crane in a suitable location to assist with the assembly and disassembly of the tower crane. The manufacturer’s instructions should be followed closely to ensure that the crane is assembled correctly and safely.
It is also important to ensure that the metal structure parts are free from fatigue damage and that the pulley assembly is free from fracture damage. The hook should be inspected for deformation, damage, and wear to ensure that it meets the required standards. The tower crane must be grounded reliably and well, and the paint should not have any peeling. Additionally, the weight must be piled according to the manufacturer’s instructions.
To assemble the tower crane, you will need to insert the lifting arm on the support shaft of the gantry platform and build the wooden pier according to the assembly dimension of the tower body lying down. The tower body and tower cap should be assembled according to the manufacturer’s instructions, ensuring that the panels with ladder-fixing gussets are face to face. The panels should be assembled using special fishplate bolts, with the heads of the bolts on the outside. The masts should be assembled between each other using shafts.
In summary, the installation and assembly of the L68A1 mast section requires careful planning, attention to detail, and following the manufacturer’s instructions closely. By taking the necessary precautions and following the correct procedures, you can ensure that the tower crane is assembled safely and efficiently.

Maintenance and Safety
Maintaining your L68A1 Mast Section is crucial for ensuring the longevity and safety of your tower crane. Here are some tips to keep your mast section in good condition:
Inspect your tower crane daily: It is important to inspect your tower crane every 80 hours to ensure that all bolts and connecting parts are properly fastened. During shift changes, the crane driver should check the fastening condition of the bolts at the connecting parts and tighten them in time if there is any loosening. This will prevent any accidents caused by loose bolts.
Clean your mast section regularly: Cleaning your mast section regularly will help prevent rust and corrosion. You can use a soft cloth and a mild detergent to clean the mast section. Avoid using abrasive materials that can damage the surface of the mast section.
Replace damaged parts: If you notice any damage to your mast section, it is important to replace the damaged parts immediately. This will prevent any further damage to the mast section and ensure the safety of your tower crane.
In addition to maintenance, safety is also important when using your tower crane. Here are some safety tips to keep in mind:
Use a lifting weight limiter: The current national standard safety regulations for tower crane stipulate that the tower crane shall be installed with a lifting limiter. If there is a lifting display device, it should be set up according to the requirements of the manufacturer. A lifting weight limiter is essential for preventing overloading accidents.
Set up walking limit: If your tower crane is an orbital crane, a limit switch should be set on its operating direction. In this way, the crane can be automatically parked within a distance of 0.5 meters when entering the correct track end, preventing any accidents caused by the crane going off track.
By following these maintenance and safety tips, you can ensure the longevity and safety of your L68A1 Mast Section and tower crane.
