A jack is a commonly used tool in places such as auto repair shops, workshops, and construction sites. Welded jacks are one type of jack that has gained recognition in the market. There are two types of jacks that are commonly accepted: cast jacks and welded jacks. As the name suggests, a welded jack is made by welding multiple metal components together, while a cast jack is made by casting a single piece. So, is a welded jack better? Let's compare.

Features of a welded jack:

Strength and stability: Welded jacks are made by welding multiple metal components together, resulting in high strength and stability. Welded joints typically have higher strength than cast parts and can withstand greater weight and pressure.

Reliability: Welded jacks form strong connections during the welding process and are less prone to loosening or breaking. Welded joints are usually very reliable and can withstand heavy loads over a long period.

Compactness: Welded jacks are typically more compact compared to cast jacks because they are assembled by welding multiple components together. This makes welded jacks more convenient to use in space-limited situations.

Repairability: Components of welded jacks can be repaired or replaced through welding, making maintenance relatively easy. Welded joints can be re-welded, restoring the jack to normal working condition.

Welded jacks also have some drawbacks, such as:

Weight: Welded jacks are typically heavier than cast jacks because they are assembled from multiple metal components. This may make carrying and moving welded jacks more difficult. Cast jacks are generally lighter and easier to handle.

Cost: Welded jacks require welding processes during manufacturing, which increases production costs. This may result in higher prices for welded jacks compared to cast jacks.

Manufacturing complexity: The manufacturing process of welded jacks is relatively complex, involving welding processes and assembly of multiple components. This may increase the complexity and cost of the manufacturing process.

In summary

The advantages of welded jacks lie in their higher strength and stability, making them suitable for lifting heavy loads of 10 tons or more. Welded structures are typically stronger and more durable. However, welded jacks are less portable and more difficult to move due to their heavier weight and multiple components. Additionally, the manufacturing cost of welded jacks is higher. If they are not frequently used for heavy-duty applications, cast jacks can be a more cost-effective option.
