The small hook machine has the characteristics of small size, light weight, low fuel consumption, high efficiency, and strong flexibility. The rubber crawler will not damage the road surface, and it is convenient to transfer and transport. It is suitable for various narrow space operations. In real life, when people are doing road construction or building construction, they often need to use mechanical equipment such as hook machines. Then, as a driver, how should they operate when operating the hook machine? What matters need attention during operation? In response to this series of questions, you may wish to read the following introduction patiently.
The hook machine is an excavator, which is a common saying in some areas, and it is also called an excavator in other places. An all-in-one machine is an earth-moving machine that uses a bucket to dig materials that are higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard.
Small hook machine operation process:
1. First, let's understand the correct operation method of the hook machine:
1. When excavating, take the surface layer first. When removing the lower layer, you cannot excavate to the bottom at one time (especially the excavation of deep trenches is especially important). For trenches larger than the width of the bucket, dig both sides first, and then dig the middle;
2. When digging a straight-line ditch, the excavator must be kept in a straight line when retreating, and the movement of the bucket can be adjusted according to the track marks left by the retreat, mainly based on the starting point of excavation; Excavation means walking in a curve or cooperating with rolling back when retreating;
3. The excavated soil should be placed upside down one meter away from the side of the ditch in turn, and upside down according to the ditch shape;
4. Confirm that there are no obstacles around the excavator;
5. Honk the horn after getting on the bus;
6. Confirm that there is no alarm on the instrument;
7. Turn the cut-off valve to ON;
8. Operation hook machine: the pedal controls the forward and backward of the whole vehicle; the right handle controls the lowering and raising of the boom, the right handle controls the retraction and release of the bucket; the left handle controls the rotation, the left handle The left and right controls the lifting and lowering of the stick.
There are three main methods of excavation:
1. Riding digging type: mainly in the open area of the site, the hook machine is parked in the middle of the ditch to be excavated and the bucket is dug between the two crawlers;
2. Side-by-side type: it refers to the relatively narrow area of the site, like a clean water channel, the bucket only digs along one side of the track line;
3. Face-to-face type: mainly for the excavation of highway culvert trenches, which means that the hook machine is parked at 90 degrees to the side of the ditch (it should be noted that when the ditch is relatively deep, the bucket cylinder may encounter the ditch) Side) Excavation of well-shaped ditches: pay attention to the control of the sequence, and use the trimming technique of 90-degree corners when excavating at the interface between ditch and ditch.
Small hook machine process standard:
When operating the hook machine, you must first confirm the surrounding conditions. When rotating, you must be aware of the surrounding obstacles and terrain, and operate safely; During the process, try not to face the final drive in the direction of excavation, otherwise it is easy to damage the travel motor or hose; during operation, ensure that the left and right crawlers are in full contact with the ground to improve the dynamic stability of the machine.
1 The right operating handle (right hand operation) controls the work of the boom and bucket:.
Pull the handle backward to lift the boom, and push the handle forward to lower the boom. When the crawler touches the ground, hold down the handle and push the excavator forward to lift it. Move the handle to the left to fold the bucket, and move the handle to the right to move the bucket eversion.
2. The left operating handle (left-handed operation) controls the forearm and its rotation. Pull the handle backward to retract the forearm. Push the handle forward to turn the forearm out. Operate the handle to the right to move the excavator to the right and turn the handle to the left to move to the left. .But many excavator hands can adjust the direction, which is what we call the positive and negative mobile phones. It is to adjust the left operating handle. After adjusting, the forearm and the turning action will be opposite. Everyone who just drives the excavator must ask the master for the opposite direction. cell phone,
Before operating, try it lightly. Do not act as a veteran or above excavator to forcefully pull the operating handle to avoid unnecessary accidents.
3. Walking pedal operation: push the excavator forward to move forward, pull the excavator backward to move backward. For quick steering, one can be pushed forward and the other can be pulled backward.
