Operation of small excavators for indoor use

For small excavators used indoors, when backhoeing, you must wait for the boom to stop before shoveling soil to prevent the bucket handle and the two sides of the boom groove from colliding with each other. When the small excavator can move on its own over short distances, it should be handled when traveling. The mechanism should be fully lubricated once. When driving, the driving wheels should be at the rear and the driving speed should not be too fast.

If the weather is particularly cold and the mini excavator is shut down for a long time, drain the engine coolant.

Generally, small excavators such as Komatsu, Carter and LEMG are operated by the forehand, with two operating handles and 9 basic movements. Each handle has four directions, front, rear, left and right, to complete the operation by pulling the handle. The specific basic operations are as follows, and the direction of the left handle is as follows : Pull to the left - extend the middle arm, pull to the right - retract the middle arm, pull forward - turn right, pull backward - turn left. The direction of the right handle is as follows: pull forward - lower the arm, turn towards Pull back - raise the arm, turn left - close the bucket, turn right - open the bucket.

During the dragline operation of a small excavator, when the shovel is full, no further shoveling is allowed to prevent overloading. When digging trenches, ditches, foundation pits, etc. with drag shovels, the distance between the machine and the slope should be determined in consultation with the construction personnel based on the depth, soil quality, slope, etc.

First, confirm the surrounding conditions; when operating, confirm the front and rear directions of the crawler tracks to avoid tipping or impact; when rotating operations, be aware of surrounding obstacles and terrain and operate safely; when operating, ensure that the left and right crawler tracks are in contact with each other. Complete contact with the ground improves the dynamic stability of the whole machine; at the same time, ensure that the left and right crawler tracks are in complete contact with the ground to improve the dynamic stability of the whole machine. Try not to face the final drive in the direction of excavation, otherwise it is easy to damage the traveling motor or hose.

The editor briefly introduced the "small excavator for indoor use". The small excavator is a multi-purpose earth and stone construction machine. It is mainly used for earth and stone excavation, loading, farmland water conservancy construction, and can also be used for land leveling, slope repair, crushing, and demolition. , trenching and other operations, so it has been widely used in road construction such as highways and railways, bridge construction, new socialist countryside construction, urban construction, airports, ports and water conservancy construction.
