Construction, the loader should be more safe operation, the following is a detailed introduction to the. Loader safety operation can be divided into the following five steps.

Check under the first machine

1, succession, the driver must according to the provisions and requirements of strict carefully check the equipment, such as the discovery of anomaly and the problem should be promptly report, and make a record.

2, check railings, ladders, support plate, a protective cover and the external surface of the device shell with and without deformation, cracks, welding and collision, a lamp and a frame is intact.

3, check the various parts of the pin and sleeve, screw loosening, wear, channeling, damage and loss. Two pin four pin and the bucket rod bucket arm is short of oil.

4, check the tire without cut and crack, pressure is normal, tire pressure ring and a pressure ring lock is normal, cover tyre fixing screw and the end whether the loosening of screws, inflatable valve cap is lost.

5, check the bucket without open welding, wear braces, iron etc. are complete, whether serious wear.

6, check the front and rear differential, final drive, wheel brake, hydraulic system, gear box, after the cooling device and the various parts of the pipe, water pipe leakage phenomenon.

7, the hydraulic oil and the table to check the hydraulic pump drive lubrication oil.

8, check the pressure gauge, such as pressure is less than 90Psi can not start the engine.

Second checks on the machine

1, check the steering and brake hydraulic oil level and brake cooling hydraulic oil surface and oil (oil quality is judged by the naked eye observation, mainly to see the color, if black, oily, need to be replaced).

2, check the engine lubrication system, cooling system and the body with no leakage phenomenon.

3, check whether the dust of the engine filter.

4, check the roll cage with open welding, crack and screw loosening.

5, check the transmission oil level and oil.

6, check the car mirror, window glass with no damage, and keep it clean, check whether the wiper is intact.

Third driving room inspection

1, check the seat and seat belt is in good condition.

2, check the instrument, indicator, alarm and the switch is in good condition.

3, check the operating handle and the body is in good condition.

4, check the fire facilities are normal (including outdoor portable fire extinguishers).

5, check the walkie talkies and random tools, utensils, etc. the records are complete and in good condition.

Fourth jobs

In 1, before the operation, must be on the area of operation environment of careful observation, to understand the situation of the action in cable, equipment failure and other obstacles, to ensure the safe operation.

2, before the operation, must be cleaned up the working surface, the formation of a sufficient operating radius, to create a good condition for the equipment and truck operations.

3, the operation and the operation of the personnel in the equipment, also not allowed to stand in the driver outside for maintenance and other work, no other irrelevant personnel aboard.

4, bucket digging is full, will be above cargo floating shake off, make the scuttle slightly leaning forward, when the bucket lifting over cab should be small arm handle operation, to prevent the bucket out goods wounding or playing bad equipment.

5, loading, especially the bucket digging full lift, travel must be slow, when reversing and other equipment firm, direction, throttle and brake to be reasonable and careful use, to ensure smooth operation.

6, at the time of loading, the first bucket to discharge low bucket as far as possible, slow discharge, cannot be loaded in bulk, so as not to hit the truck, shall not be installed in the partial car, mining should be straight dug into.

7, the bucket lift height to arm back device Limited (effective) and should not reach the arm cylinder out of limit, in order to avoid the cylinder and oil pipeline damage.

8, are not allowed to use the "floating" position to lift a load of bucket, digging in the torque converter lock when not under normal circumstances.

9, met with windy weather, avoid wind operation.

10, the operation, the former equipment should be promptly cleaned up the working surface, especially in the soft and muddy place, must be thoroughly processed, to confirm the error before the operation, so as to avoid soft and sink into the equipment.

11, the installation should cooperate with each other to contact, stagger the unloading time, so as to avoid the collision bucket. In gob area operations, to clear the roadway influence scope, take necessary measures before operation.

12, the operation, the operating area is not allowed to have pedestrians, if necessary, the first signal loader to stop the operation before entering the work area.

13 and when the lubricating oil, add oil and cooling water and troubleshooting, the driver must the bucket into the front position on the ground, turn off the engine, to get started braking, take key, leave the driving chamber can be carried out.

In 14, operation and running, no cross pressure cables and pipelines, not passing over tonnage bridge.

15, in the area of the fire zone and the temperature is too high, so as not to damage the tires, when necessary, to take safety technical measures.

16, in the operation of loading, walking and loading after the forward backward: it is necessary and pull equipment to make contact with each other, to confirm the safety of the rear can be carried out.

17, in close to the high-pressure line of work, the body and the cargo each section of the high voltage line shall not be less than 4m.

18, flammable items prohibited abandonment, the car should promptly clean up debris, so as not to cause fire.

19, the machine is equipped with fire extinguishers must be complete and effective, otherwise the report in a timely manner, to repair or replace, the driver must be familiar with the fire extinguishing device is used with a method and fire extinguishing method.

20, encountered the fire to immediately the machine stop to the appropriate place, shut off the engine, to brake and to report on the leadership, and actively take remedial measures.

21, up and down equipment, must be in the face of equipment, hands up and down, to prohibit the back of the device up or down.

Fifth parking

1, parking bucket smoothly put on the ground, to the parking brake, allow the engine to run at idle speed for 5 min, the engine cooling after flameout, it is strictly prohibited to stall the engine is running at high speed.

2, should choose the safe and smooth area when parking.

3, parking and other equipment around the distance shall not be less than 2m before and after the interval shall not be less than 5m.

4, are not allowed to park in the following places:

1) major transport corridors or ramps.

2) intersection.

3) within 15m from the bottom line of the step slope.

4) umbrella eaves or movable block below.

5) large equipment blind area.

6) the turning radius of the excavator.

5, parking will be placed in the "neutral" position, to the brake, turn off the engine and the power switch, take off the key, close the window, lock the door.
