= Excavator, we are not new to Jinan and even the whole country. After all, the advertisement of Lanxiang is too popular. Because of the limitation of excavator itself, we need to cooperate with the flexible arm of excavator in many scenarios to speed up the construction period, but we still need to pay attention to a lot of operation specifications.
1. After installing the elastic arm of the excavator, the manipulation difficulty of the excavator will increase. Therefore, in the operation and walking hours, it is necessary to ensure that the site is flat and solid, if it is soft, it should be padded with sleepers or pads, and in the marsh area, roadbed treatment should be done first, or the special crawler board for wetland should be replaced.
When starting operation, the upper limit of excavation height and depth should not exceed the functional rules of the machine itself except for loose soil.
2. Because the excavator's elastic arm is longer and heavier than the standard arm, and its action inertia is larger, it is lighter than that of the standard arm in operation, the operation process should be smooth, the action should not be too fast or too violent, and the emergency braking should not be appropriate. In addition, in order to ensure safety, after installing the elastic arm of excavator, it is forbidden to replace the large excavators which exceed the standard capacity, and when working in flat workplaces, it is forbidden to sweep or tamp the ground with the bucket.
3. The items to be inspected before the excavator elastic arm is operated should meet the following requirements: the lighting, signal and alarm devices are intact; the fuel, lubricating oil and hydraulic oil are in accordance with the rules; the articulation parts are firmly connected; and the hydraulic system is free from leakage.
When working, the elastic arm of excavator should adhere to the horizontal position as far as possible, brake the walking mechanism, and tighten the track. The trembling up and down should not be too violent, and the frame or track should not be knocked when falling.
