    Precautions
    Precautions for use of P.PB series harrow bucket rock loader

    The wire rope (especially empty rope) of the rake bucket is easy to swing during the rock loading process. The driver must have a reliable protective device on the operating side. The driver should send a signal to drive others to pay attention before driving. It is strictly forbidden to stand or carry out other work within the travel range of the bucket when loading rocks.

    Avoid tightening the two handles at the same time to prevent the bucket from flying up.

    If the harrow bucket is blocked or overloaded during the rock digging process, it should not be pulled forcibly.

    When working on the winch, at least three turns of wire rope should be left on the drum.

    Do not stack piles too high in front of the feed tank, and do not pile too much piles in the tank to prevent accidents caused by overload of the winch and the gangue and rake bucket jumping out of the tank.

    When using a pneumatic cart cylinder to push a heavy truck, you must pay attention to safety and send a signal first so that others can pay attention.

    After the rock is loaded, the harrow bucket should be pulled to the feed trough, and then the tail wheel unloaded from the head will be placed in the harrow bucket to prevent it from being buried by vermiculite after firing.

    After the rock loading is completed, the two control handles should be located at the release position, and the handles should be removed and placed on the trolley, and then the rotary valve of the pneumatic system should be turned under the slot to prevent smashing when firing.

    Before firing, remove the anti-glare light installed on the side of the middle tank and place it under the tank to prevent shock damage.

    After firing, the tanks, cables, and anti-skid devices should be checked before driving.

    If the shunting disc is used, after the installation is complete, pay attention to whether the piston rods of the air cylinder of the empty cart and the air cylinder of the heavy cart have all been retracted into the cylinder barrel to avoid damage to the piston rod. And the vermiculite on the shunting disc should be cleaned in time.

    P.PB Series Rake Bucket Rock Loader Maintenance and Management

    Maintenance and Management

    After wiring, the electrician should pay attention to the direction of rotation of the drum. When viewed from the reducer side, the drum should rotate counterclockwise. When the two drums rotate in opposite directions at the same time, the one at work should prevail.

    Always pay attention to whether the tightness of the brake band and auxiliary brake band is appropriate, whether the winch is flexible, and whether the work is reliable. If you find that the internal gear cannot be held or disengaged, you should adjust the adjustment bolt of the brake band to make it suitable.

    Always check the rope for wear and tear and replace it when it breaks.

    Grease each sheave bearing once a month, and add 90 ~ 150 industrial gear oil to the winch reducer once every three months, and add 90 ~ 150 industrial gear oil to the planetary gear transmission every month.

    When refueling the planetary transmission, care should be taken not to allow the oil to fall on the brake surface of the drum and the brake belt. If oil spots are found in the above parts, wipe them clean.

    When using in level lanes, check the oil level of the oil mist device of the pneumatic system every day. If the oil level is found to be insufficient, add lubricating oil in time.

    Always pay attention to whether the wire rope joint is firm and reliable to prevent pulling.

    Check the connection bolts for looseness and loss once a week, tighten the loose parts, and make up the missing parts.

    Clean the machine once a week to clean up leaks, slag and mud.
