Product Description-----Excavator Demolition Boom
What is an Excavator Demolition Arm?
An Excavator Demolition Arm is a specialized attachment designed to
extend the demolition reach and capabilities of a standard
excavator, especially for demolishing tall buildings. These arms
are used to safely demolish buildings, bridges, and other large
structures. Key features include:
1. Extended Reach: Allows the excavator to reach greater heights, often up to 30
meters or more, making it ideal for tall building demolition.
2. Heavy-Duty Construction: Designed to handle the additional stress and forces generated
during demolition, especially when used with attachments such as
hydraulic shears or breakers.
3. Customization: Demolition arms can be customized to the specific requirements of
a project, including arm length and compatibility with a variety of
attachments.
4. Safety: Enhanced operator safety is a top priority, and some models
feature a tilting cab and better visibility for precise demolition.
This attachment is very effective for controlled demolition in
urban environments and is often used in conjunction with hydraulic
attachments such as pulverizers, shears, or breakers. These systems
allow for precise demolition without compromising the structural
integrity of surrounding buildings.

Zhonghe Machinery Factory Advantages of Three-section Demolition
Boom
The Advantages of our demolition boom excavator:
1. The demolition arm we designed can be completely lowered, and
the accessories we carry can be rotated without disassembly.
In the transport state, this arm can also rotate, while other manufacturers' designs cannot rotate and will hit the
track plate.(P1)
2. The opening angle of the demolition arm can be larger, basically reaching 180 degrees, allowing the demolition height to be higher.
We have enlarged the pin of the bucket cylinder and adopted a 90-degree pin to ensure that the pin is not prone to problems under
high-intensity operations(P2)
3. We currently use the best products on the market in terms of
pipe design, pipe materials, and joint materials.
We strictly control the processing requirements, and must open grooves for welding and conduct trial assembly before leaving the factory to ensure precision control.
We shortened the distance between the internal ribs to increase the rigidity of the demolition arm and ensure toughness,
but also increased a certain amount of weight, which improved the quality of the product.
4. Seamless precision steel pipe
5. Q690D for boom's upper and lower cover
6. Adopt 90mm pin to avoid pin breakage
7. The pipeline is hidden to avoid being smashed
8. Hydraulic pipelines section design, convenient for later
maintenance

Related building demolition attachements for excavator demolition
arms
Double cylinder shear: The double cylinder shear adopts a specially made reinforced
slewing bearing. The teeth of the slewing bearing are processed
with high frequency, so it has better wear resistance and longer
service life. This reinforced slewing bearing has a greater
load-bearing capacity and can withstand loads in various directions
at the same time. It is the one with the largest load-bearing
capacity among slewing bearing products of the same level and can
be used in harsh working conditions such as high-altitude
demolition.
Rock hammer/breaker hammer: Suitable for mining, construction, demolition, highways,
railways, ships, metallurgy, municipal gardens, etc. The impact
energy-enhanced structure design of the breaker hammer; it adopts
the optimal design concept, increases the piston and cylinder
stroke, and uses the same diameter of the piston and drill rod, so
that the breaker hammer and the main machine match better,
reasonably utilizes the highest output energy, saves energy, and
achieves the highest work efficiency; it is manufactured using
high-quality materials and special precision technology.
Hydraulic pulverizer: It is suitable for demolition operations such as separating
reinforced concrete.
1. Made of Hardox 500, light weight and wear-resistant.
2. The oil cylinder adopts honed tube and imported HALLITE oil
seal, with short working cycle and long life.
3. The pin is made of 42CRMO alloy steel with built-in oil channel,
high strength and good toughness.
4. The blade is made of wear-resistant alloy steel, resistant to
high temperature and deformation.
Multi crusher/Multi shear: It is suitable for the demolition of high-rise buildings in the
old city renovation and the demolition of abandoned factories,
solving the problem of high-altitude operations; at the same time,
it prevents the occurrence of safety accidents.
1. The scissor body is made of Hardox steel plate, which ensures
maximum strength and best wear resistance;
2. The oil cylinder is installed in reverse, mainly to protect the
oil cylinder rod, avoid damage, and extend the service life of the
oil cylinder.

FAQ(Some frequently asked questions):
Q: Are you a manufacturer?
A: Zhonghe machinery offered a wide range of attachment parts for
excavators and dozers. Such as long reach arm, demolition arm,
telescopic arm, standard bucket, rock bucket, cleaning bucket,
tilting bucket, etc. We know that the perfect combination of
high-quality cast steel products and a moderate price is the key to
the success.
Q: What material is used for the demolition arm?
A: Most demolition arms are made of Q355B material. Customers
require lighter weight and better quality. We can use Q690D
material, but the price will be higher.
Q.The difference between the demolition arm and the two-stage long
reach arm?
A: The maximum angle of the general long reach arm after
straightening is 150 degrees, while the angle that the demolition
arm can open is about 180 degrees, which can almost be made into a
straight line. So under the same length, the demolition arm has a
higher demolition height. The two products have different focuses.
The long arm focuses on deeper digging depth, and the demolition
arm focuses on higher demolition height.
Q: What are your terms of payment?
A: We prefer T/T (50/50) payment terms, and for trial orders, we recommend using Ali Credit Insurance for added security.
