Application

Application:

It can be used for all forms of access and support structures in the building and construction industries,
shipbuilding, off-shore construction, and industrial maintenance. Our scaffolding consists of galvanized
high-strength steel modular components that are assembled together using integral wedge connectors. 

 

Our Advantages

Advantage

         Quality control:
         * We have specialized QC testers to check the quality of the products according to different customers
         requirement. Usually, it's a random inspection, and we also offer 100% inspection at a reasonable price
         if required.
         * We have IQC to check the dimensions and surface of the incoming material
         * We have PQC to inspect full-course during the manufacturing processing
         * We have FQC to inspect all the anodizing/plating and other finishes products from our supplier and
         proceed with the professional quality and appearance inspection before shipping.

 

Packaging & Shipping

Packing:
1. Generally, the total net weight of a loaded container is 22 tons to 26 tons, which needs to be confirmed before loading.
2. Different packages are used for different products: 
---bundles: timber beam, steel props, tie rod, etc.
---pallet: small parts will be put in bags and then on pallets.
---wooden cases: it is available on customer's request.
---bulk: some irregular goods will be loaded in bulk in the container.

Delivery:
1. Production: For full container, normally we need 20-30 days after receiving the customer's down payment.
2. Transportation: It depends on the destination charge port.
3. Negotiation is needed for special requirements. 
 

FAQ

 

     FAQ:
 

1. What is a Base Jack?
A Base Jack is a type of adjustable support used in construction to provide stable and level support for scaffolding, formwork, or temporary structures. It typically consists of a screw thread that allows the height of the support to be adjusted, making it useful for leveling and stabilizing construction elements on uneven ground.

2. What is the purpose of a Base Jack?
The main purpose of a Base Jack is to:

• Adjust height: It allows precise adjustments to the height of scaffolding or formwork to ensure level and stable placement.

• Provide stability: It helps distribute the load evenly across the base of temporary structures, such as scaffolds or formwork systems.

• Level uneven surfaces: The Base Jack is especially useful for leveling structures on uneven or sloped ground, ensuring proper alignment and safety.

3. Where are Base Jacks used?
Base Jacks are commonly used in:

• Scaffolding systems: To support and stabilize scaffold frames, ensuring they remain upright and secure during construction.

• Formwork systems: To support the formwork used in concrete construction, particularly for vertical elements like walls, columns, or foundations.

• Shoring systems: To provide temporary support for structures or elements that need extra reinforcement during construction.

4. What materials are Base Jacks made of?
Base Jacks are typically made from steel or galvanized steel, as these materials provide the necessary strength and durability to support heavy loads. The galvanized coating helps protect against corrosion, especially when used in outdoor or damp conditions.

5. How do Base Jacks work?
Base Jacks operate through a threaded screw mechanism, allowing the user to adjust the height of the support by rotating the jack. The process involves:

• Placing the Base Jack at the base of a scaffold, formwork, or shoring system.

• Adjusting the screw mechanism to raise or lower the jack until the desired height is reached.

• Ensuring the Base Jack is securely fixed to prevent any shifting once the structure is in place.

6. What are common issues with Base Jacks?
Common problems with Base Jacks include:

• Corrosion: If not properly coated or maintained, Base Jacks can rust, reducing their load-bearing capacity.

• Wear and tear: Frequent adjustments or improper use can cause wear on the threads, making it harder to adjust the height accurately.

• Instability: If the Base Jack is not properly installed or aligned, it may fail to support the structure evenly, leading to potential safety issues.

7. How can you maintain Base Jacks?
To maintain Base Jacks:

• Regularly inspect for corrosion or damage, especially if they are used in damp environments.

• Lubricate the threads to ensure smooth height adjustments and prevent jamming.

• Check for wear on the jack's base and threads, and replace any components that show signs of significant damage.

8. Can Base Jacks be reused?
Yes, Base Jacks are designed to be reusable. With proper maintenance and regular inspections for wear and damage, Base Jacks can be used on multiple projects without issue. They are commonly reused in scaffolding and formwork systems across different construction phases.

9. How much weight can a Base Jack support?
The load capacity of a Base Jack depends on its design and material strength. Standard Base Jacks can typically support several tons of weight. However, it's important to consult the manufacturer's specifications to ensure the jack is rated for the specific load it will carry in your project.

10. Why is a Base Jack necessary in construction?
A Base Jack is essential in construction because it provides the adjustable and stable foundation needed for scaffolding and formwork systems. Without the ability to adjust the height and ensure level placement, temporary structures may become unstable, which could lead to safety hazards, equipment damage, or delays in the construction process.
