1. Why do we need loader ramps?
Safe and efficient operation is the basic purpose of loader ramp design. Completing a large amount of earthwork and material loading and unloading operations in a short time is a problem that must be solved in loader operations. The application of ramps can effectively improve the efficiency and safety of loader operations.
2. Key points of ramp design
1. Slope
The slope refers to the ratio of the height difference between the two ends of the ramp to the length of the ramp. It is generally expressed as a percentage. A large slope can improve operating efficiency, but it will also bring many safety hazards. Therefore, it is necessary to determine the slope size according to the needs of the operation and the topography.
2. Length
The length of the ramp should be determined according to the working conditions. Too short a length will affect the climbing ability of the loader, and too long a length will occupy a lot of land resources. Generally speaking, the length of the ramp should not exceed 40 meters.
3. Width
The width of the loader ramp mainly depends on the preparation width of the operation and the width of the vehicle. Generally speaking, the width of the loader vehicle passing through the ramp should be more than 3.5 meters.
4. Material selection
Ramp material selection should be determined according to geological conditions and operational needs. Generally speaking, different materials are required for the upper and lower layers of the ramp. The upper layer can be made of relatively hard stone, and the lower layer can be made of soft soil or gravel.
III. Construction skills
1. Pay attention to safety
Pay attention to safety during construction. Warning signs and isolation facilities should be set up at the construction site, and a dedicated person should be assigned to direct and supervise the construction.
2. Correct construction
During construction, the principle of "bottom-up, inside-out" should be adhered to. First, the pit excavation and lower layer filling should be carried out, then the upper layer of stone should be laid, and finally the slope should be processed. The ramp should be kept flat, the slope should be uniform, and the compaction should be appropriate.
3. Operation skills
When operating the loader, pay attention to the following points:
(1) When the slope is large, you should shift to a high gear, accelerate slowly, and avoid sudden braking.
(2) After loading, keep the throttle stable, and go downhill slowly when leaving, avoiding sharp turns and braking.
(3) When using a ramp machine for construction, it can effectively improve labor efficiency and construction quality.
In short, ramp design and construction is one of the key links in loader operation. Mastering the ramp design principles and construction techniques can effectively improve the efficiency and safety of loader operations and create more value for production.
