Testing Methods
  • Visual Inspection: Examine weld seams for surface defects like unevenness, undercuts, or spatter.
  • Non-Destructive Testing (NDT): Use advanced techniques such as ultrasonic, X-ray, or magnetic particle testing to identify internal defects.
  • Strength Test: Apply pressure or load to assess the welds' load-bearing capacity.
Operation Stage
  • Conduct immediately after completing the welding process.
  • Address any defects identified before assembly to avoid further complications or costly rework.

2. Lifting Test
Purpose:The lifting test ensures the container can handle the designed load and additional stresses during lifting and transportation. It evaluates the strength and stability of lifting points and the overall structure.
Testing Methods
  • Load Test: Simulate lifting scenarios by applying loads exceeding the rated capacity.
  • Lifting Point Check: Verify the strength and integrity of lifting ears and points to meet international standards.
  • Dynamic Testing: Assess the container's response to conditions like sudden movements or uneven loads, ensuring stability.
Operation Stage
  • Perform this test after completing structural welding and assembly but before applying surface treatments.

3. Watertightness Test
Purpose:The watertightness test is essential to confirm the container’s resistance to water intrusion. This ensures the container can protect its cargo from environmental factors such as rain, snow, or humidity.
Testing Methods
  • Rain Test: Use high-pressure water jets or simulate heavy rainfall to check for leaks.
  • Seal Check: Focus on critical areas like door seals, welded seams, and joints to ensure they meet water resistance standards.
Operation Stage
  • Conduct after installing door seals and completing welding but prior to surface treatments. This stage allows easier identification and repair of any leakage points.

4. Paint Test

Purpose:The paint test ensures the durability and visual quality of the container’s surface coating. It evaluates the paint’s adhesion, resistance to corrosion, and overall appearance under various environmental conditions.
Testing Methods
  • Visual Inspection: Check for uniformity in the coating, ensuring it is free of bubbles, cracks, or peeling.
  • Adhesion Test: Utilize cross-cut or pull-off methods to verify the paint’s bond to the container surface.
  • Film Thickness Measurement: Measure the film thickness of the paint on the surface of the container using an electronic coating thickness gauge or a magnetic coating thickness gauge to determine the quality of the paint.
Operation Stage
  • Perform this test after completing the painting process to validate the container’s visual and protective qualities.

Recommended test sequence
  • Welding test → watertightness test (preliminary) → lifting test → surface treatment and painting → watertightness test (final)
  • After passing all final tests, product acceptance and preparation for delivery.

Conclusion:

Each of these tests plays a vital role in ensuring the quality and reliability of TLS special containers. By addressing potential issues at the appropriate stages of production, manufacturers achieve:
  • Enhanced Safety: Mitigate risks of structural failures, safeguarding personnel and cargo.
  • Increased Durability: Ensure the container can withstand challenging environments and prolonged use.
  • Operational Efficiency: Minimize downtime and repair costs by resolving issues before delivery.
  • Compliance with Standards: Guarantee adherence to international quality and safety regulations.

Through these rigorous testing processes, TLS ensures that its special containers meet the highest standards of performance and reliability, providing customers with products they can trust for their most demanding applications.

Mastering Container Lifting Techniques: A Comprehensive Guide

9/8/2023

 
Introduction
Container lifting is a crucial aspect of logistics and shipping operations worldwide. Efficient and safe container lifting ensures the seamless movement of goods from one location to another. Whether you're a seasoned professional or a newcomer to the industry, understanding the various techniques, equipment, and safety measures associated with container lifting is essential. In this comprehensive guide, we will delve into the world of container lifting, exploring its importance, methods, equipment, and safety considerations.
 
Why Container Lifting Matters
Container lifting is the process of raising and moving standardized cargo containers, which come in various sizes and configurations, such as 20-foot and 40-foot containers. Proper container lifting is vital for several reasons:
  1. Efficiency: Efficient container lifting processes reduce loading and unloading times, enabling shipping companies to optimize their schedules and meet tight deadlines.
  2. Safety: Mishandling containers can lead to accidents, injuries, and property damage. By following proper lifting procedures, the risk of accidents is significantly reduced.
  3. Cost Savings: Efficient container handling reduces operational costs associated with labor, equipment maintenance, and potential damage to goods.
 
Container Lifting Techniques
Several container lifting techniques are employed depending on the situation and equipment available. Here are some common methods:
  1. Forklifts: Forklifts equipped with container spreader attachments are commonly used for lifting and moving containers within a terminal or storage facility. They are versatile and well-suited for handling containers in confined spaces.
  2. Reach Stackers: Reach stackers are specialized container-handling vehicles designed for stacking and transporting containers efficiently. They are often used in container yards.
  3. Cranes: Mobile cranes or gantry cranes are utilized for lifting containers on and off ships or railcars. These heavy-duty machines are essential for container terminal operations.
  4. Straddle Carriers: Straddle carriers are large machines that can pick up containers and transport them short distances. They are commonly used in ports and rail terminals.
  5. Manual Handling: For smaller containers or in situations where machinery cannot be used, manual labor may be employed. However, this should be done with caution and adherence to safety protocols.
 
Container Lifting Equipment
To carry out container lifting effectively, the right equipment is essential. Key container lifting equipment includes:

Offshore Container Vertical Impact Test

11/29/2022

 
1. During the test, a uniformly distributed load equivalent to the difference between the rated mass and the tare weight of the container should be placed in the container and fully bolted.
2. The ground on which the offshore container falls should be a flat concrete floor or other hard surface. The ground may be covered with planks, which shall not exceed 50 mm in thickness.
3. Lift the marine container tilted so that the angle between the side beam and the end beam connected to the lowest angle on the bottom of the container and the ground is not less than 5°. On the bottom surface of the container, the height difference between the lowest corner point and the highest corner point should not be greater than 400 mm.
4. During testing, the corner with the worst stiffness should be selected as the lowest impacted corner.
5. The lowest corner point of the offshore container should be more than 50 mm away from the ground. The initial impact velocity of the offshore container touching the ground shall not be less than 1m/s.
6. After testing, the offshore container shall not show significant permanent deformation or damage. Small repairable open welds and deformations are allowed.
TLS will not proceed to the next production step until the marine container has passed the vertical impact test

WHAT BASIC TESTS WILL THE FACTORY DO BEFORE THE CONTAINER DELIVERY?

1/21/2022

 

1 WELDING INSPECTION
Welding inspection of containers, including inspection and NDT.
The whole inspection process runs through the manufacturing process of containers, not limited to the final product, and adjusts production at any time to ensure welding quality.
 
2 LIFTING TEST
In addition to the test required by international container safety convention, our company will also carry out a two-point and four-point lifting test.
The two-point lifting test mainly tests the anti-deformation ability of containers at sea under extreme conditions, and the four-point lifting test mainly tests the carrying capacity of containers at sea. Both tests do not allow permanent deformation of containers at sea during accelerated crane lifting.
 
3 DROP TEST
The main purpose of the drop test is to examine the impact of the lifting and placing of containers at sea to ensure that the cabinet can withstand the damage caused by the impact.
 
4. WATER TIGHTNESS TEST
The container body is sprayed with high-pressure water from all directions, and will be checked in all directions after spraying to ensure that there is no water in it.
