Description:In recent years, the application of excavator olecranon shears in scrap steel processing has become increasingly popular. It is especially suitable for the dismantling of steel structures and factory structures, the dismantling of used vehicles, and the shearing of heavy waste in stock yards. With its flexible and convenient operation, high efficiency and low energy consumption, it is favored by the scrap steel industry. It is a new concept and high-efficiency equipment in the scrap steel industry and will soon become the mainstream equipment for scrap steel and metal dismantling in the future.

Answer:

In recent years, the application of excavator olecranon shears in scrap steel processing has become increasingly popular. It is especially suitable for the dismantling of steel structures and factory structures, the dismantling of used vehicles, and the shearing of heavy waste in stock yards. With its flexible and convenient operation, high efficiency and low energy consumption, it is favored by the scrap steel industry. It is a new concept and high-efficiency equipment in the scrap steel industry and will soon become the mainstream equipment for scrap steel and metal dismantling in the future.
However, most of the operators of olecranon shears are directly transferred to the operation of olecranon shears directly from the operation of earthmoving and breaking hammers, and they will directly bring some habits of operating earthmoving and breaker excavators to the eagle. Mouth cut operation is coming. However, in view of the special structure and performance of the olecranon, some bad operating habits need to be strictly prohibited to avoid unnecessary damage to the olecranon and the excavator itself.
First, it is strictly forbidden to use olecranon for hammering operations. The olecranon is different from the breaking hammer. The olecranon is a more complicated device with precise rotating parts, oil supply parts and electrical components. The violent impact will cause the failure of these components and cause the olecranon to be damaged and malfunction. Work. In addition, the movable shaft of the olecranon and the bushing and the blade are all very precise matching structures, and the violent impact can easily lead to the deformation and damage of the structure.
Second, it is strictly forbidden to use olecranon scissors to swing the car with a pestle. Excavator drivers are familiar with an operation called "swinging with a pestle", which is to support the bottom surface with a bucket and breaker in front of the forearm, pressurize the front end of the chassis, and then rotate the chassis to change the direction of the crawler to turn on the spot. , Instead of traditional turning methods. Ordinary excavator attachments are generally simple and bulky, such as bucket breakers, etc., which will not cause problems. But the olecranon is lighter, more sophisticated and more complex than these attachments. In particular, the rotating parts of the olecranon are easily damaged during this operation. Most of the olecranon slewing supports, motors and gears are damaged because of this poor operation.
Third, it is strictly forbidden to operate the motor for turning while cutting. Due to the structure of the olecranon, a large motor and transmission device cannot be configured, and it can only meet the rotation position of the cutting head in an unloaded state. If the motor is operated while cutting, the motor will often be overloaded, and it is easy to damage the motor and the transmission gear.
Fourth, it is strictly forbidden to use olecranon for tearing operations. Many drivers like to bite the material and tear it off when using olecranon shears for demolition and shearing operations. However, this operation can easily cause damage to the forearm cylinder of the excavator. In severe cases, it can directly cause the forearm. The piston rod of the cylinder broke on the spot, causing danger and injury to personnel and vehicles. In addition, this kind of operation can easily lead to the loosening of the bolts of the jaw knife of the olecranon, which will damage the jaw knife in the subsequent cutting.
Fifth, it is strictly forbidden to use olecranon for swing sweeping operations. Many operators like to use the cutting head to sweep or move the material to the side while cutting the scrap steel on the ground. This kind of job is also easier to damage the olecranon. Generally, they think that the cut material is not heavy, and sweeping will not cause any damage to the cutting head. However, in this operation, the operator cannot clearly and accurately judge the distance between the cutting head and the bottom surface every time. When the cutting head touches the ground, it will cause varying degrees of damage to the rotating connection bearings and motor drive gears of the olecranon. Damage is also detrimental to the excavator arm and connecting shaft.
Having said so many prohibitions, what is the correct operation? The correct operation is to use the excavator to drive the olecranon to find the position and angle that needs to be cut, and then cut it. Try not to allow the olecranon to withstand additional external force, let alone the impact of the olecranon.
