How to operate the hydraulic system of the muck loader?

Date:2022-06-01

As a commonly used equipment in the mining industry, the muck loader must be operated correctly, otherwise it will cause huge danger once a problem occurs. Therefore, the following editor will introduce to you the operation method of the hydraulic system of the vehicle to avoid mistakes.

1. Turn on the main power switch of the muck loader.

2. After the button indicator light is on, start the oil pump and fan. If it is used for the first time or after rewiring, it should be judged whether the sequence is correct. If the sequence is not correct, the machine will not start.

3. Wait for 10 seconds to start up before using with pressure. If the pump is shut down for more than 4 hours, let the pump run empty for 5 to 10 minutes before it can work under pressure.

4. Lower the transport chute shovel to the ground.

5. Operate the muck loader to move forward, gather the stones, and push the ground level at the same time.

6. After confirming that the mining electric tricycle or other transfer equipment has entered the unloading part of the machine, turn the handle to the forward rotation of the conveying. If you feel that the speed of the feeding cannot keep up, you can turn the acceleration confluence handle in place.

7. Operate the pilot valve to raise the boom, extend the forearm, put the bucket in a position about a line with the forearm, then lower the boom and retract the forearm (while making the boom move up and down slightly), The stone can be scraped into the transport trough. Rotating the slewing arm can pick up in a large range, and properly retracting the bucket according to the distance of the stone will be beneficial to picking.

8. In the process of picking, always pay attention to whether the scraper chain is conveying normally. If it gets stuck, stop conveying in time, otherwise the oil temperature will rise rapidly and it will not work. The way to release the chain is to pull the conveying rotary joystick to the neutral position, and quickly move the conveying joystick back and forth, so that the scraper chain impacts quickly forward and backward, and the chain can be released. When there are stones in the transport trough, the transport lever must not be stopped at the position where the transport is reversed, otherwise the chain or scraper may be broken, which will seriously affect the production.

Therefore, when you drive the muck loader to work, you must pay more attention to the operation methods mentioned by the editor above, standardize your own operation methods, and avoid wrong operation behaviors that cause vehicle problems and endanger personal safety.
