What Environmental Factors Should Be Assessed Before Operating a Lever Hoist?​

Before using a lever hoist for heavy - duty lifting, it is essential to assess the surrounding environment to identify potential hazards. First, check the ground conditions. The ground should be level and firm enough to support the weight of the hoist and the load. If the ground is uneven or soft (such as on a construction site with loose soil), use a sturdy base plate or wooden blocks to stabilize the hoist's support structure. Second, evaluate the overhead environment. Ensure that there are no overhead obstacles such as power lines, pipes, or beams that could interfere with the lifting process. If the lifting operation is near power lines, the minimum safe distance should be maintained (for example, at least 10 feet away from low - voltage power lines). Additionally, check the weather conditions. Avoid using the lever hoist in strong winds (with wind speeds exceeding 20 mph) or heavy rain, as these conditions can affect the stability of the load and the hoist's operation. For instance, in an outdoor construction site, if a sudden gust of wind occurs during lifting, it could cause the load to swing, leading to collisions or falls.​

What Are the Correct Postures and Movements When Operating a Lever Hoist?​

Using the correct posture and movements when operating a lever hoist can not only ensure safety but also reduce physical fatigue. When operating the lever, stand in a stable position with your feet shoulder - width apart, keeping your body balanced. Avoid leaning too far forward or backward, as this can cause you to lose balance if the load suddenly shifts. When pulling the lever, use the strength of your legs and core muscles rather than just your arms. This distributes the force more evenly and reduces the strain on your arms and shoulders. Do not pull the lever at an angle; instead, pull it in a direction that is perpendicular to the hoist's body to ensure that the force is applied evenly to the internal components. For example, when lifting a heavy steel beam, if you pull the lever at a 45 - degree angle, it can cause the hoist's gears to wear unevenly and may even lead to the lever jamming. Additionally, do not use extensions on the lever to increase the force, as this can exceed the hoist's rated load capacity and cause the hoist to fail.​

How to Respond to Unexpected Situations During Lever Hoist Operation, Such as Load Slippage?​

Unexpected situations like load slippage can occur during lever hoist operation, so it is crucial to know how to respond quickly and correctly. If you notice that the load is slipping, do not panic. First, immediately stop pulling the lever to prevent further movement of the load. Then, check the cause of the slippage. Common causes include a loose hook or shackle, a worn braking system, or an overloaded hoist. If the hook or shackle is loose, carefully tighten it using the appropriate tools, ensuring that it is securely fastened to the load. If the braking system is worn, do not continue using the hoist; instead, mark the hoist as "out of service" and arrange for maintenance or repair. If the hoist is overloaded, reduce the load to within the hoist's rated capacity before continuing. In the event that the load has already started to fall, do not attempt to catch it with your hands or body. Instead, move quickly to a safe area and activate any emergency stop devices if available. After the situation is under control, conduct a thorough inspection of the hoist before using it again to ensure that all components are in good working condition.
