Vacuum cranes are often operated in high-density, so what should be paid attention to when using it? The following editor will talk about the precautions when using the vacuum hoist.

The speed of the vacuum pump of the vacuum hoist is too high, the heat is increased, and the speed is too low, which will cause the engine to knock, and the additional impact of the component will affect the life, the appropriate speed, the larger adjustment position of the hand throttle should be adjusted in advance. The pump type 50QZXDG-45 is suitable for 500-600 rpm. Turning the tank on a flat ground and turning the tank on a sloping road will distort the components and cause failures, and may cause equipment rollover accidents. Open the rear door and window when turning the tank, and open the rear fan before turning the filling of the tank. Never close the door leaf and turn the tank, because the center of gravity shifts back and there is a risk of rollover.

When the clutch oil pump power take-off box and the vacuum pump power take-off box, the engine is idling, and the clutch pedal is fully stepped on, and the clutch pedal should be slowly raised during the clutch. When entering the bottom of the tank or for maintenance with the lifting device raised, support rods and safety blocks must be used. When transporting materials, you must use the back door housing clamping device. Because there is no anti-wave board in the tank and the center of gravity is high, the vacuum hoist must be driven at medium and slow speeds without heavy changes and sudden braking.

When in use, turn on the alarm switch, pull the hand throttle handle to a larger position, and observe the tachometer to make it reach 500-600 rpm. Place the four-way valve switch lever in the suction position, and check whether the material lifting device is operated correctly, whether the air pump is running abnormally, and the vacuum gauge is normal. Heavy objects with too large diameter, such as cotton yarn, stones, containers, etc., will affect the lifting height and range. At this time, it should be replaced by a four-way valve control operation. The switch lever is placed in the neutral position and the ball valve is placed in the open state.

The above is the relevant content of the precautions for vacuum suction cranes to share with you. I hope that through the above content, everyone has a better understanding and understanding of vacuum suction cranes. If you have any other questions, please contact us.
