1. Operate the pilot valve of the mucking rock loader in order to raise the boom, extend the forearm, place the bucket to a position approximately in line with the forearm, then lower the forearm and retract the forearm (while making the upper Move), you can chop the stone into the transport trough. Rotating the swing arm can pick up in a large range. Depending on the distance of the stone, the bucket can be retracted appropriately to facilitate picking. Generally, the arms should not be moved to the limit position during the picking process to avoid frequent transient impacts and shorten the service life of the machine. At the same time, the excessive oil temperature caused by the overflow of the overload valve can be avoided. Do not be careful not to allow the bucket to directly hit the transport slot, otherwise the tank will be seriously deformed.
2. During the picking process of the mucking rock loader, pay attention to whether the scraper chain is normally transported. If it is stuck, stop the transport in time. Otherwise, the oil temperature will rise rapidly due to overload, and you cannot continue to work. The method to release the stuck chain is to move the forward rotation control lever to the neutral position, and then move the forward and backward control lever to make the scraper chain quickly and positively impact, and the stuck chain can be released. When there are stones in the transport trough, do not stop the conveying control lever at the position where the conveying is reversed. Otherwise, the chain or scraper may be broken, which seriously affects the production.
3. When you need to stop the brake during the walking of the mucking rock loader, put the foot pilot valve in the neutral position. If you stop for a long time, you need to press the head production plate against the ground.
4. The mucking rock loader should start the electric bell as a warning signal when walking or reversing.
