Chains container lashing

Types of Container Lashing Chains

Lashing is very important in securing cargo during transit to avoid damage and loss. Chains container lashing is one of the methods used to secure cargo on a container ship. It involves the use of heavy-duty chains and binders to tie down and restrain cargo. This chain lashing can be done in two main types as discussed below.

• Spring Lashing

  Spring lashing is a widely used method in container vessel lashing. It uses large elastic springs known as lashing rods. These rods are used to secure containers on deck and prevent them from moving. The rods are tensioned horizontally between the container rows and secured at both ends. This tension creates enough force to keep the containers in position even in rough weather or high winds. The spring lashing system is crucial for maintaining the integrity and safety of container stacks during maritime transport. By preventing shifting and displacement, spring lashing minimizes the risk of cargo damage and loss. This lashing method is especially important for valuable and fragile goods that require extra care and security.

• Twist Lock

  A twist lock is a locking device used to secure containers on ships during transportation. Container lashing devices provide safety and assurance that the containers will arrive at their destination intact. This is achieved through a combination of pins, hooks, and locking mechanisms that firmly attach containers to the ship's deck. Twist locks are typically used at the bottom corners of containers, where they connect to the ship's lashing points. This secures the containers and prevents them from swaying or shifting, which can cause damage or pose safety risks. Together with other lashing tools like ropes and chains, twist locks provide a robust and reliable system for securing cargo at sea.

Specifications and maintenance of chains container lashing

• Checking for Wear and Tear

  Inspecting lashing chains for signs of wear and damage is important. This includes checking for elongation, which is when the chain links stretch out and the chain gets longer. It makes the chain loose and weak. Other things to look for are broken or cracked links, bent hooks, or damaged fittings.

Salt buildup can cause corrosion and rust on the chain. After washing, using a soft brush or cloth to remove any stuck-on dirt or grime is necessary. One should also clean the lashing equipment, like hooks and shackles, to ensure everything stays in good shape.

• Lubrication

  Chain lashing should be lubricated often to keep it from wearing out. This is important for the places where the links rub against each other. Using the right kind of oil or lubricant keeps everything moving smoothly. It also stops rust from building up on the chain. When oiling the chain, one should use a clean cloth to wipe off any extra lube. This prevents dirt and dust from sticking to it.

• Load Limit and Proper Usage

  One should always follow the manufacturer's instructions regarding the maximum load capacity of the lashing chain. Overloading the chain can cause it to break or weaken. Using the chain for tasks other than those intended can also lead to problems. For example, using a chain with hooks that do not fit correctly could result in unsafe lashing.

• Replacement

  If any parts of the chain lashing system are damaged beyond repair, it is important to replace them promptly. This prevents accidents or failures while lashing containers. When replacing parts, ensure that the new components match the specifications of the original system.

• Record Keeping

  One should maintain a record of all inspections, maintenance activities, and replacements done on the chain lashing equipment. This helps keep track of the condition of the materials over time. It also ensures compliance with safety regulations.

• Training and Safety Practices

  Personnel involved in lashing chains container should receive proper training in maintenance procedures and safety practices. This ensures everyone knows how to handle the equipment safely and how to maintain it properly.
