The L68B1 mast section is made of high-strength steel and is designed to provide maximum stability and support for tower cranes. It is a key part of the tower crane’s structure, providing the necessary height and rigidity to lift and move heavy loads safely and efficiently. With its durable construction and reliable performance, the L68B1 mast section is a popular choice among construction professionals who demand the best in quality and performance.
Overview of L68B1 Mast Section
If you are in the market for a mast section for your tower crane, the L68B1 Mast Section is one option you might want to consider. This particular mast section is a popular choice for many construction projects due to its durability and reliability.
The L68B1 Mast Section is made up of four panels, two of which have telescoping lugs while the other two do not. These panels are assembled using 20 special fishplate bolts, with the heads of the bolts on the outside. The panels that have ladder-fixing gussets must be face to face when assembled.
One of the benefits of the L68B1 Mast Section is its versatility. It can be used with a variety of tower crane models, making it a great option for those who need a mast section that can be used on multiple projects. Additionally, the L68B1 Mast Section is designed to be easy to install, which can save you time and money on your construction project.
Another advantage of the L68B1 Mast Section is its strength. This mast section is made from high-quality materials that are designed to withstand the rigors of heavy lifting and construction work. This means that you can rely on the L68B1 Mast Section to hold up under even the most challenging conditions.
Overall, the L68B1 Mast Section is a reliable and versatile option for those in need of a mast section for their anti-tower crane. Its durability, ease of installation, and strength make it a great choice for a variety of construction projects.
Design Specifications
Material Composition
The L68B1 mast section is made of high-quality steel material, which is durable and has excellent corrosion resistance. The steel composition of the mast section meets the requirements of relevant standards and specifications. The main components of the mast section include the lattice column, diagonal brace, horizontal brace, and connecting bolts. These components are carefully designed and manufactured to ensure that they meet the required specifications.
Structural Dimensions
The L68B1 mast section has a standard length of 2 meters and is composed of four panels, two of which have telescoping lugs, and two do not. The panels that are provided with ladder-fixing gussets must be face to face. The panels are assembled by 20 special fishplate bolts, and the heads of the bolts are on the outside. The extension length of the lattice column should be ≥ 1.5m, and the pile stirrup at the position where the lattice column extends into the pile should be doubled, so as to ensure that the additional pouring length of concrete meets the requirements of relevant specifications.
Load-Bearing Capacity
The load-bearing capacity of the L68B1 mast section is determined by the structural dimensions and the material composition. The mast section can withstand a maximum load of 68 tons and has a high safety factor. The deformation and corrosion of main structural parts shall be within the allowable range of the specification. The setting of platform, walkway, ladder, and guardrail shall meet the specification requirements. The structure and bearing capacity calculation of the tower crane must be carried out according to the relevant standards and specifications to ensure the safety of the tower crane operation.
In summary, the L68B1 mast section is a well-designed and high-quality component of a tower crane. Its material composition, structural dimensions, and load-bearing capacity are all carefully designed and manufactured to ensure that it meets the required specifications and standards.
Installation and Assembly
Assembly Instructions
Assembling and installing the L68B1 mast section requires careful attention and adherence to the manufacturer’s instructions. The following are general assembly instructions that should be followed:
Begin by assembling the lower section of the mast. This involves installing the foundation section, support section, and standard section in turn.
Once the lower section is assembled, install the outer jacket swivel part, then install the tower cap, rear arm, and finally install the lifting arm.
Install the remaining counterweight, ensuring that it is evenly distributed.
The balance arm should be placed and anchored to the standard section of the tower body. Install three oblique support rods, and fix one end of the suspension rod for the time being without installing the fourth.
Through winding wire rope, the wire rope of the hoist is passed through the cab to the pulley block of the Tower Cap, and is finally fixed at the head of the crane. All the length of the rope and the distance between the two pulley blocks should be calculated and determined.
Safety Precautions
When assembling and installing the L68B1 mast section, it is important to observe the following safety precautions:
Always wear appropriate personal protective equipment (PPE), such as hard hats, safety glasses, and gloves.
Use proper lifting equipment, such as cranes or hoists, to lift and position the mast sections.
Follow proper rigging procedures when lifting and positioning the mast sections.
Ensure that all bolts and fasteners are tightened to the manufacturer’s specifications.
Never exceed the maximum load capacity of the crane or hoist being used to lift and position the mast sections.
By following these assembly instructions and safety precautions, you can ensure that the L68B1 mast section is installed safely and correctly.
Operational Use
Compatibility with Crane Models
The L68B1 mast section is compatible with various tower crane models. It is important to ensure that the mast section is compatible with your crane model before use. Refer to the manufacturer’s guidelines or consult with a qualified technician to ensure that the mast section is compatible with your crane model.
Maintenance Procedures
Proper maintenance of the L68B1 mast section is crucial to ensure safe and efficient operation. Regular inspections and maintenance procedures should be performed on the mast section to ensure that it is in good working condition. The following maintenance procedures should be performed:
Regularly inspect the mast section for signs of wear and tear, such as cracks or corrosion.
Keep the mast section clean and free from debris.
Lubricate all moving parts of the mast section as per the manufacturer’s guidelines.
Check all bolts and nuts regularly to ensure that they are properly tightened.
Replace any damaged or worn components immediately.
By following these maintenance procedures, you can ensure that your L68B1 mast section is in good working condition and ready for use when you need it.
