The crawler mucking loader is also called crawler mucking loader, which is mainly used for rock rake crawler mucking loader is mainly used in coal mines, metallurgical mines, tunnels and other engineering tunnels to be loaded with mining carts or buckets to carry out loading operations. The main equipment for mechanization.
(1) There are two operation handles on the crawler mucking loader console. The right and back direction of the right handle controls the forward and backward movement of the trolley, and the left and right direction controls the tilting movement of the slag picking arm. The left and right direction of the left handle controls the slag scraping plate to be raised and lowered, and the left and right direction controls the rack to swing left and right. The right and left handles push and control the proportional valve, which can control the running speed of the trolley according to the push angle. The larger the push angle, the faster the speed; the other two handles push and control the reversing valve, which can only be reversed and the speed cannot be adjusted. The adjustment is pre-adjusted through a throttle valve in the hydraulic system.
(2) There is a limit switch in front of the crawler mucking loader rack. The car will stop automatically when the switch is hit. Due to the different moving speed of the operating trolley, the inertia effect will cause the stopping distance of the trolley to be different. The position of the front travel switch is generally set to stop the trolley without impacting the bumper after a medium-speed impact. Due to the ladle position limitation during actual operation, the trolley does not need to reach Front limit position. There are two limit switches at the back of the frame. The one at the front is a deceleration switch. When it hits it, it will output a signal to control the car to decelerate. When the car hits the back limit switch, it will stop quickly.
