holdexcavating machineryRotate the upper rotating platform to a 90 degree angle with the slope, and check the maximum inclination angle at which the upper rotating platform can rotate towards the uphill side.
preparation:
1. Check that the lubrication of the rotary gears and bearings is good
2. Load the bucket with full load. The weight of the bucket load (W: ton) can be calculated using the following formula:
W=MX1.5
In the formula: M=full bucket capacity (CECE; m ')
1.5=specific gravity of soil
3. Fully retract the forearm cylinder and extend the bucket cylinder, so that the top pin of the forearm is at the same height as the foot pin of the boom.
4. Climb the slope and rotate the upper rotating platform to a 90 degree angle with the same slope
5. Keep the hydraulic oil temperature at 50 ± 5 * C
Measurement:
1. Select the following switch positions:
Engine control dial: maximum position
E-mode switch: OFF
HP mode switch: OFF
Work mode selector: General purpose mode
Automatic slow switch: OFF
2. Operate the rotary control lever to the full stroke to rotate the upper rotary platform towards the uphill side.
3. If the machine can rotate, measure the tilt angle of the cab floor.
4. Increase the angle of the slope and repeat steps 2 and 3. Check in both clockwise and counterclockwise directions.
5. Conduct measurements three times.
