ProductsFeatures:

1. Excavator boom lengths range from 20-32 meters depending on the construction project.

2. The telescopic boom uses low-alloy high-strength steel plates, offering high tensile strength.

3. The product is lightweight and structurally strong. The boom and arm can utilize a completely new enclosed design. Special manufacturing standards and the use of large-scale equipment allow for one-piece molding of the excavator boom, minimizing the load during use. Alternatively, a combined submerged arc welding solution can be used to meet diverse customer needs.

4. Adaptable to most special engineering operations, capable of performing tasks that standard excavator configurations cannot.

5. Telescopic booms for special municipal engineering projects can increase working speed and accelerate the work process.

6. 24-hour on-site service and guidance are available.

OperatePrinciple:

The built-in hydraulic cylinder telescopic boom is made of wear-resistant and high-temperature-resistant square steel. Through high-precision machining, the first, second, and third sections are completely and tightly fitted together. Work is completed by pushing or retracting the boom using a stroke cylinder. This type of telescopic boom has a limited working depth, focusing on vertical excavation, but has a very small turning radius, enabling it to handle more complex working conditions than a two-section extended boom.

The external hydraulic cylinder telescopic boom is also made of high-strength steel formed square tubing, consisting of three or more sections. It utilizes steel cables and pulley systems to freely extend and retract, achieving maximum excavation depth. It is widely used in urban street construction, such as subway entrance excavation and elevated bridge foundation pit excavation.

ApplicationScope:

Telescopic booms are generally divided into those with built-in hydraulic cylinders and those with external hydraulic cylinders. Built-in cylinder booms operate on the same principle as truck-mounted crane booms, while external cylinder booms are designed based on pulley block principles. They are primarily used for excavating caissons and deep foundation pits. Built-in cylinder telescopic booms have an excavation depth of less than 12 meters, while external cylinder booms are available in depths of 25-35 meters. Various types of grab buckets can be mounted on the front.
