The excavator extension arm is divided into two-stage excavator extension arm and three-stage demolition machine extension arm:
< < The two-stage excavator extension arm is mainly used for soil and sand transportation highway slope modification and dredging of rivers.
<
< . We must first understand the application fields and functions of the excavator extension arm:
< The excavator extension arm is divided into two-stage excavator extension arms and three-stage excavator extension arms
< The two-stage excavator's extended arm is mainly suitable for river dredging, earth and stone foundation deep trench excavation, etc.
< The three-stage excavator's extended arm is mainly suitable for high-rise building dismantling operations, etc.
< < Things to pay attention to when modifying the excavator extension arm during the warranty period:
< If you modify the excavator extension arm for a new excavator within the warranty period, you must coordinate the warranty issues with the excavator seller. Warranty requirements. There are many people who did not coordinate with the excavator seller before modification within the warranty period. During the warranty period, the complete machine agent made excuses for your excavator's warranty or refused to find various reasons, etc., causing disputes over after-sales service to avoid future disputes. Before refitting a new machine, a relevant agreement must be reached with the complete machine seller. After the excavator standard arm is modified to the excavator extension arm, the excavator load increases. Of course, the professional design is based on the excavator model and is designed to ensure the quality of the excavator extension arm from comprehensive aspects such as working performance and safety performance.

< Problems that should be eliminated when converting an old excavator into an excavator extension arm:
< When modifying an old excavator standard arm into an excavator extension arm, you must first measure the performance of the excavator such as hydraulic output. Can a certain pressure be reached? Can the traveling mechanism, turntable structure, etc. be able to bear the length of the excavator's extension arm? Reasons such as the age of the old excavator and the length of construction work have a direct impact on the performance of the excavator itself, such as being unable to lift the arm and walking slowly without digging force. For these reasons, it is difficult for the excavator to achieve the efficiency that an extended-arm excavator should have after being modified into an extended-arm arm. Before modification, enter the quality inspection of the excavator. Through the quality inspection, you will have a clearer understanding of the performance of your own excavator before you can choose a more suitable extension arm for modification!
< <. Clarify the operating requirements and working environment of the excavator's extended arm.
< The length of the excavator's extension arm is directly related to the excavator's own mass and output pressure. When selecting an excavator extension arm, we must determine how long the excavator extension arm should be configured based on the excavator's operating environment, operating requirements, its own quality, and the capacity of the bucket and other ancillary devices. The two-stage excavator extension arm is used in construction operations. The three main parameters of excavation height, excavation depth and working radius are often involved, while the extension arm of the three-stage building demolition machine often involves the three main parameters of lifting height, safe working height and working radius. Only comprehensive factors can determine how long the excavator extension arm can be equipped with this model.
< < Reference parameters for configuration length of modified excavator arm extension for corresponding models
< Two-stage excavator arm extension weight and arm configuration: - Ton machine weight can be equipped with meter excavator arm extension - The machine weight per ton can be equipped with an excavator extension arm of meters - The machine weight per ton can be equipped with an excavator extension arm - The machine weight per ton can be equipped with an excavator extension arm - The machine weight per ton can be equipped with an excavator extension arm - The machine weight per ton can be equipped with an excavator arm extension Meter excavator with extended arm three-section building demolition machine with extended arm Machine weight and long arm configuration: - Machine weight per ton can be equipped with meter demolition extended arm - Machine weight per ton can be equipped with meter demolition extended arm - Machine weight per ton can be equipped with meter demolition arm The ton machine weight of the floor can be equipped with a long arm. The ton machine weight can be equipped with meters. The ton machine weight can be equipped with a meter. The ton machine weight can be equipped with a dismantled floor and an extended arm. The above parameters are for reference only.
