- Q:Heavy machine soldier 3 crab excavator, where I can't get on
- I've been looking for that place for a long time... It's very weirdFirst of all. In 1 wandering into the factory on the ground is 3 rooms, it is the factory, the roof is excavator, don't go into the factory... Now go outside, there is a place that can trigger automatic plot, look up, sway the crab excavator swagger before others go directly to... I, this story no trigger...

- Q:Introduction of excavator
- First, the definition of excavators, excavators, also known as mining machinery (excavating machinery), is digging with bucket mining materials above or below the surface of the machine, and loaded into the transport vehicle or dump to the stacker of earthmoving machinery. The main materials are soil, coal, sediment and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, and excavator as one of the most important construction machinery models in engineering construction, the correct selection is also more important. Two, a brief history of excavator first hand excavator has been developed for more than 130 years of history, has experienced a gradual development process of automatic hydraulic excavator driven by steam rotary bucket excavator to the internal combustion engine and electric drive rotary excavator, application of mechatronics technology during the. The first hydraulic excavator was successfully invented in japan. Due to the application of hydraulic technology, 1940s has been installed in the tractor equipped with a backhoe hydraulic excavator suspension, in early 1950s, and have been developed in the mid towed rotary hydraulic excavators and crawler hydraulic excavator.
- Q:The hero League digger listens, will the enemy show it on the map?
- On the big map, the enemy movement will have obvious ripples, and it will not appear on the minimap.If the enemy to escape to the excavator, into, you will hear a very clear sound, like terror footsteps, so when the excavator on the mobile side if you can find the enemy immediately. Play with the excavator, you must bring headphones.It is worth noting that, if the enemy is stationary, you can not hear, such as the enemy 3 BUFF blue eyes sweep ambush, you can not face the grass so dangerous, but to find the angle shrink gun (by the shrink gun in the enemy will be exposed to the blue grass field) watch Party A. Generally, the enemy who hears the enemy is sure to hit the ground gun in a locked position, and when he is not sure, he will plug into the eye and shrink the cannon. It's very difficult to hide.
