How do common loaders work?(2)

The working principle of a loader is mainly based on the hydraulic system and mechanical transmission system. Here are a few key steps and principles of how a loader works:

1. Power source: Loaders are usually powered by a diesel engine. The engine transmits power to the hydraulic pump and traveling system through the transmission system.

2. Hydraulic system: The hydraulic system of a loader is the core of its operation. The hydraulic pump obtains power from the engine, generates a high-pressure oil flow, and drives the hydraulic 

cylinders to work.

3. bucket action:

   - Load: the operator through the control lever or pedal, control the flow of hydraulic oil to the corresponding hydraulic cylinder, so that the bucket down to contact the ground, the material is 

shoveled into the bucket.

   - Lifting: when the bucket is full of materials, the operator operates the control lever again, so that the hydraulic oil flows to the bucket lifting cylinder, and the bucket rises, lifting the materials to a

 certain height.

   - Tilt: The bucket can be tilted forward or backward to facilitate unloading or loading of material. This is usually achieved by controlling another hydraulic cylinder.

4. Travel System: The travel system of a loader allows the machine to move between loading and unloading material. Wheel loaders use tires, while track loaders use tracks. The operator controls the 

loader by controlling the steering wheel or joystick to move forward, backward, and steer.

5. Unloading: When the loader moves to the unloading point, the operator tilts the bucket by means of the control lever and the material flows out of the bucket to complete the unloading process.

6. Control System: Modern loaders are usually equipped with advanced control systems, including electronic control units (ECUs) and various sensors, to improve operational accuracy and efficiency.

Loaders are designed so that they can adapt to a variety of work environments, including rough terrain and harsh weather conditions. Widely used in construction, mining, agriculture, logistics and 

many other fields, they are an important tool for improving material handling efficiency.
