Our designs allow for interchangeable use of digging buckets and grab buckets.
The first one is clamshell bucket ,usually use for Subway deep digging project .
The second one is the grab bucket , compare to the clamshell bucket , the grab bucket have power
,can grab the stone.
The last is the standard bucket , use for telescopic boom the bucket need do the special design .
ZHONGHE triple quality control system
The first system is the technical design drawing review mechanism,
The second system is the semi-finished product review mechanism,
(each process has a detection testing for the previous process)
The third system is the finished product testing.
(Before painting, the overall inspection is carried out to check
whether the design size matches the welding size, and whether the
installation size meets the design requirement.)
To sum up, every single ZHONGHE product has been passed the above
three-stage inspection system to ensure that is qualified before
shipping.

Some questions and answers that may interest you
Q: Are you a manufacturer?
A: We are a manufacturer/supplier of excavator arms and attachments.
We have a super large factory. The factory area is several times
that of our competitors. It is the largest excavator attachment
factory in Guangdong Province. It has complete production equipment
and its products have been exported to more than 60 countries
around the world.
Q: Why does the telescopic arm have the difference between a shell
bucket and a grab bucket?
A: Generally, shell buckets are easy to use for silt and sand, and
can dig a large volume with higher efficiency. However, in general
sand and stone work, shell buckets have no digging force and are
limited by the opening, so the efficiency of shell buckets will be
reduced. Grab buckets are more suitable for this kind of work.
However, due to the overall weight of the grab bucket, the volume
of the grab bucket is generally smaller than that of the shell
bucket, but in work with more stones, the advantages of grab
buckets are more obvious.
Q:Is it better to use a single cylinder or a double cylinder for
the shell bucket equipped with a telescopic arm?
A:We always use the double cylinder design and never use the single
cylinder design. It has the advantages of low failure rate,
convenient maintenance, and less oil leakage. What are the
disadvantages of the double cylinder? The first is that the shell
bucket with a double cylinder is heavier, and the synchronization
of grabbing is worse. The overall weight of a single cylinder is
lower, and the synchronization is better, the grabbing efficiency
is higher, but the failure rate is higher.
Q:What is the material of the telescopic arm?
A: The arm tube is made of BS900E, and other parts are made of
Q3558, which is lighter and more durable. We use a thickness of
6mm.
