Excavator grab 2, broken hammer ( Also called impact drill) Use percussion drill excavator to dig stone, gravel, floor, etc. Excavator hammer 3, scarifier using scarifier excavator can have crack rock excavation, frozen soil, asphalt pavement performance, etc. Scarifier cut out 4, hydraulic shears use hydraulic excavators can be broken down, rescue operations, etc. Hydraulic shears, dig into the cable, the person will get an electric shock? In the process of construction, there are often dig the cable of the accident. Dig into the cable, but the fact is that the car of the operator will not get an electric shock. Reason is the excavator is a & other; Throughout the equipotential body &; All to bring, the big arm to touch the high tension line, the operator has a high voltage, but because of the potential inside the car are equal, so the car is with the voltage but it could not form current, and by the same token, the bird in the telegraph pole so you don't get an electric shock.

Comfortable modern excavator cab after six, excavator in the car? After excavators in car accident, can't blind touch, otherwise will be deeper. Desire & other; Drawing & throughout; If not the correct approach is: 1, the excavator from the shore, very close to the big arm forearm straight, tick the scoop on the firm ground, scoop a little bit to pull the excavator. 2, if the excavator is not deep, can be found in the nearby objects such as steel, wood, logs mat under the chain belt of excavator, excavator can share out. 3, if trapped car serious or self-help fruit, do not take any action, take the time to find the crane, large excavator to the rescue.
