What are the different characteristics of the excavator telescopic arm
|
|
When it comes to deep foundation excavation, you may not be unfamiliar with it. It is often encountered in cities, such as the foundations of high-rise buildings, subway stations, etc. The methods of excavation are also varied, and the excavators and cars are usually driven in large scenes. To carry out construction at the bottom of the pit, long-arm excavators are used for smaller scenes, and ordinary excavators are generally not required for the excavation of shafts in subway stations for smaller scenes. In fact, the specific situation may be more complicated, such as the soil is not suitable for cars to drive into the foundation pit, or the cost of repairing the road is too high. The telescopic arm of an excavator, as everyone who has used it, knows that it can easily handle this complex working environment.
Product features of telescopic arm excavator
The effective working distance is large and the working height is high. The telescopic arm structure can reach a long distance and can directly work over obstacles; it has good working safety performance; it is easy to replace our various attachments and improve the machine function.
Applications
Applicable to: bridge foundation pit (pier dredging), subway foundation pit (subway exit), sewage treatment pond (caisson), underground garage, wharf dredging, river dredging, cofferdam dredging, excavation, etc.
There are more benefits of excavator telescopic arm:
Telescopic arm and clamshell bucket can realize vertical excavation
In recent years, the telescopic arm and clamshell bucket have gradually been used in more and more foreign countries, because it can effectively take into account the depth and efficiency of digging, and the application occasions have also been expanded, especially those that cannot be opened by ordinary excavators.
Suitable for small spaces
The clamshell bucket is not a new tool. It has been used for decades, but it is generally not used for ordinary excavation. Now that the clamshell grab is installed on the excavator with the telescopic arm, it gives full play to the advantages of both parties. The telescopic arm can extend the bucket to a depth of about 30 meters for excavation, and it does not take up much space when it is lifted, which is convenient for loading.
The cab extends forward for easy observation
Nowadays, some excavator manufacturers have made the cab that can extend forward for this application, which is convenient for the driver to observe and greatly improves the efficiency. For example, the shaft of the subway station can also be excavated in this way.
It usually takes up little space on the ground
The clamshell bucket and telescopic arm have a greater excavator depth than an extended arm excavator, and the bucket is also larger, so the efficiency is much higher than the latter. At the same time, it requires less swing space, suitable for compact locations, and does not require roads. Of course, this tool can not be installed with just an excavator and is usually only used for excavators over 20 tons.
Loading at close range is much more convenient and efficient
In actual application, depending on the situation, there are often other excavators in the foundation pit, with clamshell bucket to achieve higher construction efficiency.
