How can a novice avoid "injury" to the shovel teeth when operating a loader?

Operational details during the initial stages are often overlooked. A 1:1 scale bucket force diagram shows that when the loader is initially started, if the bucket is immediately lowered to the ground and forced forward, the shovel teeth will experience an impact force three times greater than normal operation. The correct approach is to idle the loader for three minutes after starting. After the hydraulic system pressure stabilizes, slowly lower the bucket, allowing the shovel teeth to lightly touch the ground at a 15° angle, and then advance at a steady speed. Data from a training school shows that novices who master this technique experience a 58% reduction in abnormal shovel tooth damage.

Angle control during material loading and unloading is crucial for protecting the shovel teeth. When loading a truck, after the bucket is raised to bed height, the shovel teeth should be kept at a 30° angle to the horizontal plane during unloading, rather than fully tilting. This prevents the shovel teeth from being violently impacted by falling material. When unloading sticky materials, gently shake the bucket two or three times before lowering it, allowing most of the material to fall off. This minimizes scraping of the shovel teeth against the bed. Xiao Li, a new worker at a logistics park, shared his experience: "I used to think I had to flip the bucket all the way to the bottom to unload cleanly, and ended up wearing out a pair of shovel teeth in just two weeks. Now, I follow the angles my master taught me, and they're still working perfectly fine after a month."

Emergency handling in unusual working conditions demands even more skill. When encountering bumps on the ground, adjust the bucket's height in advance to avoid them rather than forcibly running over them. When stuck in mud, don't slam on the accelerator to try to escape. Instead, slowly operate the bucket to support the ground and help you get going, preventing the shovel teeth from breaking due to uneven force. These seemingly basic, standard procedures actually serve as an "invisible shield" protecting the shovel teeth.

The process of becoming an experienced worker is also a process of developing a rapport with the equipment. Understanding the "force language" of the shovel teeth ensures efficient and safe operation every time, which is essential for professional advancement.
