What are the excavation characteristics of a forward shovel excavator?
1 Answers
The excavation action characteristic of a forward shovel excavator is "forward and upward, forced soil cutting"; while the characteristic of a backhoe shovel is "backward and downward, forced soil cutting". The specific details are as follows: 1. Different applicable conditions: The forward shovel excavator can excavate soil above the parking surface, and is suitable for dry foundation pits with an excavation height greater than 2m, but it is necessary to set up ramps. The backhoe excavator can excavate type I to III soils below the parking surface, and is suitable for foundation pits, foundation trenches, and pipe trenches with a depth not exceeding 6m. It is also suitable for wet soil, soil with high moisture content, soil below the groundwater level, and soil in areas with high groundwater levels. 2. Different bucket sizes: The bucket of a forward shovel excavator is larger than that of a backhoe excavator of the same equivalent. Due to the arrangement and connection structure characteristics of the boom and stick, this type of forward shovel excavator is not suitable for excavating working surfaces below the parking surface, but is suitable for excavating working surfaces above the parking surface. 3. It has sufficient lifting force and pushing force, and performs forced pushing motion, making it suitable for all types of soil.
