A telescopic arm for excavators includes a fixed base, a sliding
extension, a wire rope, and a hydraulic telescoping cylinder. By
varying the number of sliding sections, the operational reach and
excavation depth can be customized. It is commonly paired with a
bucket for deep digging applications, including handling soil,
sand, and coal.
The two-section telescopic boom is crafted from LG700 steel for
high strength, with Q355B used for additional components to
maintain a balance of durability and reduced weight. Features
include:
22-ton bucket cylinder for enhanced digging force
Strengthened reel with enlarged spring plates
Multi-layer reinforced bearings for extra durability
LG700 steel box construction for high load capacity
Reinforced pivot end to handle greater excavation forces
High precision machine of Zhonghe Machinery Manufacturers
Large, floor-mounted double-sided boring and milling lathe:
- Increased Precision and Consistency: The double-sided boring and milling lathe enhances operational
accuracy and consistency.
- Post-Welding Process: After welding, the machine bores through the hole, ensuring the
parallelism and verticality of the shaft.
- Main Responsibility: This machine is primarily used for post-welding boring of large
and small arms and buckets to ensure accuracy.
- Simultaneous Boring: The double-sided boring lathe performs boring on both sides at the
same time, guaranteeing even accuracy.

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: Is the length of the telescopic arm the total length or the
digging depth?
A: The length of a two-stage telescopic arm refers to the digging
depth. For example, a 14-meter telescopic arm means that the
maximum digging depth is 14 meters, so it is called a 14-meter
telescopic arm. The actual arm length is not only 14 meters.
Q: What material is the telescopic arm made of?
A: The arm tube of the telescopic arm is made of a690 or HG785
material, and the material of other parts is a355B material.
Q: What are your terms of payment?
A: We prefer T/T (50/50) through Ali Credit Insurance as a trial
order.
Q: Are you always delivered on time?
A: We can't promise about the sea freight but what we can do is
shorten our lead time while keeping the same quality level. So
there will not be any problem even if the sea freight is delayed
for a couple of days.
