How to operate mini excavators ?
[Efficient operation method of excavator]
Specific operation methods are as follows:
1.While lifting the big arm, turn left and right to quickly reach the borrow point.
2.While lifting the large arms, the rods can be deployed and retracted to quickly reach the borrow and discharge points.
3.While collecting the bucket rod, the shovel-head can be scratched to quickly remove soil and release soil.
4.While turning left and right, open the shovel too quickly.
How to correctly operate the excavator, some safety matters that should be paid attention to when the excavator is as follows:
1, excavators shall be parked on solid and flat ground. A tire excavator shall top the legs.
2, the excavator shall be in the horizontal position and break the travel mechanism. If the ground is mud, soft, and subsidence, apply sleepers or board or cushion.
3, bucket excavation should not each eat too deep, not too fierce, so as not to damage machinery or cause dumping accidents. Be careful not to impact the tracks and the frame when the bucket falls.
4, Personnel who cooperate with the excavator to clear the bottom, flat ground, and slope repair shall work within the rotation radius of the excavator. If it must work within the excavator rotary radius, the excavator must stop turning and stop the swing mechanism before working. At the same time, the personnel on the machine should take care of each other, closely cooperate, to ensure safety.

5, excavators shall not stay within the range of loading activities. If unloading on the car, then dump the bucket until the car stops firmly and the driver leaves the cab. When the excavator rotates, please avoid crossing the bucket from the top of the cab. When unloading, keep the bucket as low as possible, but be careful not to impact any part of the vehicle.
6, excavator rotates, the rotary clutch shall rotate smoothly with the rotary mechanism brake, and sharp rotation and the emergency braking are prohibited.
7, bucket shall not do swing, walking in front of the ground. Do not arm and walk when the bucket is full and suspended.

8, shovel operation, do not continue to prevent overload. When digging ditches, ditches, canals, foundation pits, etc., negotiate with the constructors according to the depth, soil quality, slope, and other conditions to determine the distance from the convenient slope of the machinery.

9, back shovel operation, the soil must be shoveled after the arm is stopped to prevent the handle and the arm groove.
10, crawler excavator moves, the arm rod shall be placed in the walking forward direction, and the bucket height is not more than 1 m from the ground. And break the swing mechanism.
11, The excavator shall be behind the drive wheel and arm above; the drive wheel shall be in front and arm. The rod shall be at the rear. The upper and lower slope shall not exceed 20 °. Down-slope should be slow driving, variable speed, and neutral taxi is not allowed on the way. Excavators shall be paved when passing through the track, soft soil, an
d clay pavement.
12, When excavating scattered soil on a high working surface, remove large stones and other debris from the working surface to avoid collapse. If the soil is excavated in a suspended state and can not collapse naturally, it shall be treated manually, and it shall not be hit or pressed with a bucket to avoid accidents.
13, excavators shall not be close to overhead transmission lines, whether operating or traveling. If working or passing near the high and low-pressure overhead line, the safe distance between the machinery and the overhead line
must meet the dimensions specified in Schedule I. In thunderstorm weather, it is strictly prohibited to work near or below the overhead high-voltage line.
14, works near cables, the cable must be directed and displayed on the ground and shall be maintained
Excavate at a distance of 1 m away.

15, The excavator should not turn too quickly. If the curve is too large, the turn shall be within 20 ° each time.
16, tire excavator due to the steering blade pump flow is proportional to the engine speed when the engine speed is low, special attention should be paid when turning during driving. Especially when downhill and sharp turn, we should change the low-speed gear in advance, to avoid the use of emergency braking, resulting in a sharp reduction in the engine speed, so that the steering speed can not keep up and cause accidents.
17, electric excavators must remove the capacitor on the switch box when connecting the power supply. Non-electrical personnel is strictly prohibited to install electrical equipment. Running the cable shall be moved by staff wearing rubber shoes or insulation gloves. And pay attention to prevent the cable from wiping out and leakage.
18, excavator, maintenance, and tightening. If abnormal noise, odor, and excessive temperature rise occurs during work, stop immediately for an inspection.
19, During the maintenance, overhaul, lubrication, and replacement of the top pulley. The arm rod, the arm rod shall be lowered to the ground.
20, Lighting good night lighting in working area and cab.
After the excavator works, the machinery shall be removed from the working area in a safe and flat place. Turn the body-positive, make the internal combustion engine to the sun, the bucket landed, and put all the levers in the "neutral" position, brake all brakes, shut off the engine (clean the cooling water in winter). Do routine maintenance in accordance with the maintenance procedures. Close doors and windows and get locked.

When excavators can be transferred at a short distance, the general distance of crawler excavators shall not be more than 5 kilometers. Tire excavators can be unrestricted. However, do not do long-distance self-transfer. When the excavator can be transferred at a short distance, the walking mechanism shall be fully lubricated. When the driving wheel should be in the rear and the walking speed should not be too fast.
Excavators shall be directed by experienced hangers. During loading and unloading, excavators shall not turn or turn on the ramp. If dangerous conditions occur during loading, lower the bucket to assist in the brake, and then the excavator will slowly retreat.
