How does a loader perform soil scraping?

Mining loader Suitable for earthwork but not rock work. It can still operate on soil with a small amount of mixed stones, but must stop immediately to remove larger stones, wood, metal or obstacles encountered during loading. Operating the loader in waterlogged clay or rainy weather is prohibited. It is not allowed to work in areas exceeding the comprehensive slope limit (longitudinal slope >10%, transverse slope >18%) to avoid tipping or excessive load on one side of the tires.

For the maintenance of loader accessories, first lift the door, then raise the bucket. Avoid raising the bucket when the door is fully closed as much as possible, which helps protect the door mechanism and hydraulic pipelines. Before excavation and loading, retract the soil unloading device to the rear of the bucket, open the door, and lower the bucket to be close to the ground.

When scraping soil, the bucket should slowly cut into the soil, and the height of the door from the ground should be controlled at around 300mm. When excavating hard ground or loading clay, move the bucket up and down. If the soil condition is poor, use a bulldozer for assistance—pay special attention not to let the bulldozer’s blade damage the loader’s rear tires.

First, the loader accessory manufacturer shall formulate the loader’s operation and travel route. Turns should be as few as possible and arranged during the return trip to facilitate machine travel. Do not make sharp turns less than 100° when towing the loader; use reverse to turn. When passing through potholed areas, drive at low speed to bypass deep potholes over 700mm as much as possible. For soil loading and unloading, the road needs to be leveled, and straight-line travel is preferred. The length of the working section shall not be less than the distance required to fill the bucket (about 30m). The length of the unloading section shall be sufficient for the bucket to empty the soil before reaching the end. The soil transportation distance of 50～500m is more economically beneficial.
