Let’s see how to protect the subminiature excavator during the rainy season.
1.About the choice of parking lot
Where can I stop safely? First, you need to look and judge whether the surrounding geography is safe, away from rivers and hilly slopes where landslides may occur. It's not a great car park under a big tree. Thunderstorms are prone to lightning strikes, and if the wind is strong, blowing the excavator apart can also cause significant damage.
Choose solid on-street parking. Park on concrete floors and parking lots. However, our excavator job sites are rarely glued together and most are on site. In this case, please park for a long time. Please choose on a stable surface, do not park it on a crowded floor.
Additionally, you need to do the following:
(1) Make sure that the oil tank and hydraulic oil tank caps are tightened.
(2) Be careful not to let rainwater enter the filter of the excavator air filter.
(3) Be careful not to wear the engine grease seal to prevent rainwater from penetrating into the oil.
(4) Place the breaker vertically to prevent the piston from rusting.
2. How to prevent traps
(1) Prepare surveys and tools
(2) If the water volume is large, the construction cannot be carried out. If the construction time is not urgent, drain the water first and let the construction site dry for a few days before starting work after the soil has cured.
As the owner and operator, you need to carry wire ropes and steel plates for fish ponds and sludge. Before you start, use a bucket to insert into the bottom and slope of the pond and check the softness and hardness of the mud. In general, be careful when putting it in a 3/4 bucket. In particular, part of the bottom of the pond was dry, but after a few tens of centimeters it turned into sand and mud. If you can't find it, you're in trouble. The bottom of the pond can be hard, but the slopes are very muddy.
3. Watch Downhill (Stay and Retreat)
First, watch out for the downhill. If this location is not allowed, you could fall in or fall into the car. When you fail, you have to think of a way to get up. You have to keep holding back. For reference, there are the following items.
(1) Please do not go downhill. is 90 degrees
(2) Do not put the bulldozer in front of you when drowning.
(3) Under the silt driving wheel, the guide wheel is backward. If the vehicle shows signs of being stuck, pull the arm lightly to complete the operation. The arm extends further along with the bucket, and the reach of the arm is very narrow to escape.
(4) When entering the mud pit, squeeze the soil forward and squeeze the mud forward. In the 20-ton class, the mud needs to be filled with 60 cm of dry soil.
