✅ This product mainly consists of a fixed body, sliding body, steel wire rope and a telescopic cylinder. By changing the number of sliding bodies, an ideal working radius and vertical excavation range can be achieved. Generally used in combination with a bucket, it can complete deep pit excavation tasks, such as grabbing soil, sand or coal.

✅ The three-section telescopic boom is made of BS900E, and other parts are made of Q355B, which is lighter and more durable. We use 6mm thickness.

✅ Three Section Telescopic Arm Configuration

1. A set of telescopic arm
2. Two high-pressure hoses
3. Two pins
4. One clamshell bucket
5. One two-way foot switch

1. Excavator High Reach Demolition Boom Arm

✅Seamless precision steel pipe

✅Centralized lubrication system

✅The boom seat sleeve adopts all in one molding process

✅Hydraulic pipelines section design, convenient for later maintenance

2. Excavator Pile Driving Boom Arm

✅ The angle between boom and horizon can reach 88°

✅The angle between boom and arm can reach 160°

✅Comparing with the same length pile driving arm, ours can pile higher.

3. Excavator Shorten Arm

✅Stop valves prevent oil leakage when replacing breaker by bucket.

✅Multi-layer welding of pipe connectors to reduce the risk of oil leakage

✅Cylinder protective cover is beneficial to preventing the cylinder from being damaged in collision

✅Q355B material, using high-quality accessories, full weld, double plate reinforcement in the stress position, etc.

4. Excavator Sliding Arm

✅Built-in antiwear plastic slider for easy replacement and maintenance

✅The double oil seal design for the telescopic cylinder prolongs its service life

✅The whole plate is cut, not spliced, so as to be more firm and not easy to deform

✅Steel sliders are welded between the skateboards to avoid direct contact wear

6. EXCAVATOR LONG REACH

✅The pipeline we use is international seamless precision pipeline.

✅The bushing on the boom base we use graphite alloy copper sleeve ,and other place we use steel bushing for easy maintenance

✅Chamfering bevel before welding, our muti-layer welding is full and smooth with many year professional experence .

✅Rivers cleaning dregging project

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.

What type of model can directly install a 30 meter telescopic arm
A: In the absence of a nitrogen cylinder, the generally 30-meter telescopic arm can be installed by more than 450 machines, with 2.2 square shell buckets and 1 square grab buckets. If the nitrogen cylinder is added, the machine above 350 (including 350) can also be equipped with 30 meters telescopic arm and 2.2 square shell bucket. Whether it is 350 or 450 machine, the installation of 30 meters of telescopic arm is required to increase the counterweight to stabilize, 350 machine, it is recommended to increase the counterweight of 8 tons, 450 machine is recommended to increase the counterweight of 4 tons.What is a nitrogen cylinder and how does it work

What is a nitrogen cylinder and what is its working principle?
A: The nitrogen cylinder needs to be filled with nitrogen, why choose nitrogen? The first nitrogen is an inert gas, inactive; Second nitrogen, why can you install a longer telescopic arm if you install a nitrogen cylinder? The telescopic arm is relatively heavy, and the downward pressure of the telescopic arm depends on gravity, and the power support of the excavator is not required. The problem occurs when lifting the big arm, the weight of the telescopic arm during load far exceeds the weight of the original arm load, exceeds the ultimate load capacity of the big arm cylinder, and can not lift the big arm, or the phenomenon of slow lifting. In the face of this phenomenon, there are two solutions, the first is to increase the oil cylinder, the second method is to install a nitrogen cylinder. Enlarging the cylinder will not only cause the cylinder to meet the big arm, but also prone to a series of failure problems of high engine water temperature.
The second method is to install a nitrogen cylinder, the downpressure of the telescopic arm is enough, the lifting capacity is not enough, the principle of the nitrogen cylinder is to always give the big arm an upward lifting force, which increases the lifting force, while reducing the load of the engine, and fuel saving
