28-35m Super Excavator Long Reach Boom for Hitachi1200 Custom Long Reach Booms Excavator Long Arm Attachment Exporter

The extended arm of an excavator is an equipment attachment specially used for equipment that requires a larger operating range. It is commonly used in engineering projects such as deep excavation, river cleaning, and demolition of high-rise buildings. The extended arm can greatly increase the operating radius and height of the excavator, improving work efficiency and flexibility.

Zhonghe Factory Advantages of Long Reach Boom/Long Arm:

1.These 4 main weld passes, they are all double layers. We ensure the welding melts to the whole plate.

2. It can make the pass more firm and less likely to crack. 3. Here you can see the pass is full and very smooth.Our welding worker is skillful and have more than 10 years working experience, very professional.

4. Seamless precision steel pipe
5. Three layers and four passes welding
6.Lubrication concentrate system. There are 5 lubrication pipes, all concentrated here, making it easy and convenient for operators to add lubricating oil.

We use double-layer reinforcement plates at the boom base, making our long arms more durable and stronger than other suppliers.

1. The parts prone to cracking have been reinforced, and the box inside the ear seat has been reinforced.

2. The connection between the end of boom and the box has been reinforced.

3. The ear seat of the arm has been reinforced and the design mechanism has been changed.

What is the purpose of a long arm plate bevel?

Welding machines commonly used in the industry have a depth of fusion of only 3mm thick, and our long arm plate is at least 8mm thick. Our long arm plates are at least 8mm thick, and without a bevel, the welder cannot penetrate the entire weld, resulting in poor weld results and problems such as cracking of the weld at a later stage.

We make bevels mechanically, while other factories make bevels manually (as shown in the picture)
