The slag scraper is operated by hydraulic oil through the hydraulic system. There are two methods. One is multi-way valve operation and the other is hydraulic pilot operation. Different operating modes correspond to different types of slag scrapers. Wheel type The slag scraper uses a multi-way valve to operate, while the crawler slag scraper uses a hydraulic first channel operation. Both of these need to be understood, because modern mining companies use these two operating methods.
The operating lever of the multi-way valve is a six-link four-rod structure. The operation method is: the first handle on the left hand (bucket lifting and lowering, big arm steering): push the handle forward, pull the bucket stick back, and retract the bucket stick. Push the handle to the left and the big arm will turn left. Push the handle to the right and the big arm will turn right. 2. The second handle on the left hand (moving the whole vehicle): Push the handle forward and the vehicle will move forward; pull the handle back and the vehicle will move backward. 3. The second handle on the right hand {shovel mouth lifting): push the handle forward and the shovel mouth touches the ground; pull the handle backward and the car will move backward. 4. The first handle on the right hand (boom lifting, bucket lifting). Push the handle forward to lower the boom; pull the handle backward to raise the boom.
