Precautions for excavator operation and excavator driving
1. When the excavator works, it shall park on a solid and flat ground. The wheel excavator should hold up the supporting leg well.
2. The excavator shall be in a horizontal position when working and stop the walking mechanism. If the ground is muddy, soft and dangerous to sink, use sleepers or planks and pads.
3. It is not advisable to eat the earth too deep every time when excavating the bucket. The bucket should not be too strong to damage the machinery or cause overturning accidents. When the bucket falls, be careful not to impact the track and frame.
4. The personnel who cooperate with the excavator to clear the bottom, level the ground and repair the slope shall work within the turning radius of the excavator. If the excavator must work within the turning radius of the excavator, the excavator must stop turning and stop the rotating mechanism before the work can be carried out. Meanwhile, people on and off the plane should take care of each other and cooperate closely to ensure safety.
5. Vehicles and pedestrians shall not stay within the loading range of the excavator. In case of discharging materials to the vehicle, the vehicle should wait for a stable stop until the driver leaves the driver's cab before turning the bucket and discharging the materials to the vehicle. When the excavator rotates, the bucket should be avoided from crossing the top of the cab. When unloading, the bucket should be lowered as low as possible, but attention should not collide with any parts of the car.
Preventive measures for excavator gear shifting
1. Operate in strict accordance with the operating rules and driving requirements, and avoid "punching teeth" during gear shifting to minimize wear of gear pairs.
2. Strictly implement the maintenance system and strengthen the maintenance of gear shifting device. When the bar system connection of gear shifting device is not timely adjusted to ensure good performance of gear shifting device.
3. Pay attention to the maintenance and maintenance of the self-locking mechanism, and timely repair or replacement of the positioning steel ball, spring and fork shaft that reduce or lose the positioning efficiency, so as to keep the self-locking performance of the self-locking mechanism in a good state.
4. When assembling the transmission, the operation should be carried out in strict accordance with the operating rules to ensure the correct adjustment and proper tightening of all parts of the transmission. When a large downhill road surface, the driver should strictly follow the action points of the downhill operation, do not break the rules.
