A jack is a common lifting tool that can effortlessly raise or push objects without requiring excessive force. However, improper use of a jack can pose risks to both individuals and objects. Therefore, it is crucial to use a jack correctly.
The first step is to understand the performance of the jack. Jacks come in various models and types based on their load-bearing capacities. Before using a jack, it is necessary to confirm whether the jack's load-bearing capacity meets the required weight and select the appropriate model and type accordingly.
When using a jack, ensure it is placed on a flat surface and positioned vertically on the load-bearing surface to ensure stability when lifting heavy objects. The working surface at the end of the jack should be kept as level as possible.
When operating the jack, grip the handle gently and maintain moderate pressure to ensure control and stability during operation.
Before performing tasks, inspect all parts of the jack to ensure they are in good condition, especially the supports on both sides. Check for cracks or deformities during use to prevent damage to objects and ensure work safety.
From a safety perspective, it is prohibited to stand under or in front of the jack while operating it to prevent accidents.
Pay attention to the center of gravity and balance when using the jack. If the center of gravity is unbalanced, the jack may shift or tilt. In such cases, stop using the jack, rebalance, and correct the position of the load before continuing to use the jack.
Using a jack requires skill and experience. Before using a jack, thoroughly understand its performance and operation to smoothly and safely complete tasks. A positive attitude and comprehensive knowledge can enhance job safety while greatly improving work efficiency and task capabilities.
