I believe that friends who are engaged in the machinery industry must be familiar with the excavator long boom. A large number of construction machinery and equipment will be used in our municipal construction, improvement of subway traffic, sewer reconstruction, river channel cleaning, etc., and the standard excavation Machinery cannot meet all construction needs. In some special construction environments, standard excavators bring great inconvenience to our construction. At this time, all kinds of extended arms will show their power.

Let’s learn about the members of the excavator long boom family:

1.Two-stage excavator long boom: the scope of use is relatively large, and its main function is to increase the digging radius. It can be found in various sites that require large-scale excavation. The general refit size is in the range of 10-26 meters.

2.Three-stage excavator long boom: or multi-stage long boom, mainly used in the dismantling of high-rise buildings. The modification size is in the range of 20-28 meters.

3.Telescopic arm: It is suitable for engineering operations with large effective working distance and high working height, and it is necessary to cross obstacles to load and unload goods. The modification size is within 26m.

4.Extended arm of pile driver: the big and small arms are straight, the front arm is about 2.6 meters, and the vibrating hammer is suitable for driving and pulling steel sheet piles for road and railway construction or buried pipelines.

Problems that we need to be clear about in the modification
It is not recommended to refit the new machine, because after refitting the excavator long boom, the load of the excavator will increase, and the after-sales service dispute with the original factory will easily arise if the warranty period has not expired;

It is also not recommended to refit the machine below 50% new, because the machine has a long life and its performance has declined in all aspects. It is difficult to play its due efficiency after refitting. new excavator.

Before refitting the old excavator, we must first conduct quality inspections to avoid the failure of the extended arm to fully exert its due efficiency due to the unqualified performance of the old excavator after refitting.

The most suitable excavator long boom should be selected for modification according to the excavator’s performance and operating environment, operating requirements, its own quality, and the capacity of the bucket attachment. Never blindly pursue efficiency while ignoring performance and its security.
