Why More Contractors Choose Custom Excavator Long Reach Arms？
The core function of an extension boom is to overcome limitations and expand operational boundaries. It allows excavators to operate at higher, deeper, and farther distances. Based on different operational needs, extension booms are mainly classified into the following types:
By Number of Sections:
Two-Section Extension Boom: The most widely used, used to increase the excavation radius, depth, and height.
Three-Section/Four-Section Extension Boom: Commonly known as a "demolition boom," designed specifically for high-altitude operations such as the demolition of high-rise buildings.
By Operation Method:
Demolition Extension Boom: Used for dismantling high-rise buildings.
Deep Pit Extension Boom: Used for deep excavation operations such as deep foundation pits and subway tunnels.
Piling Extension Boom: Used in conjunction with equipment such as vibratory hammers for piling operations.
By Performance:
Fixed Extension Boom: Fixed length, simple structure, high load-bearing capacity.
Sliding/Telescopic Extension Boom: Adjustable length, high flexibility, suitable for working conditions requiring changes in the operating radius.
Key Advantages:
Wide Operating Range:Significantly increases digging height, depth, and radius. For example, a 40-50 ton excavator with an extended boom can achieve a maximum digging radius of 27 meters and a depth of 24 meters.
High Adaptability: Capable of handling special working conditions inaccessible to ordinary excavators, such as deep pits, high-altitude work, and underwater operations.
High Construction Efficiency: Significantly accelerates project progress in specific scenarios.
Main Features:
High Precision and Durability:Constructed with high-strength steel and a box-type structure, ensuring robustness and durability. Advanced manufacturing processes also guarantee its performance and service life.
Requires Comprehensive Modification:Adding an extended boom is a systematic project that requires comprehensive consideration of the excavator's power, hydraulic system, and counterweight balance.
Main Application Scenarios and Working Conditions
River and Water Conservancy Projects: Commonly used for river dredging and sediment removal. The equipment can clean the riverbed directly from the bank without needing to enter the water; also suitable for embankment protection and tailrace cleaning of hydropower stations.
Municipal and Infrastructure Projects: Widely used for construction pit excavation, subway tunnel excavation, and municipal pipeline laying, requiring long-distance or deep excavation.
High-Rise Demolition Projects: Three-section and above extended booms are the main equipment for the safe demolition of high-rise buildings, chimneys, and viaducts, allowing operators to stay away from danger zones. The front end is usually equipped with hydraulic shears or a hydraulic breaker.
Special Terrain and Working Conditions: Suitable for slope trimming on highways or for excavating and stacking high-level cargo piles in storage yards.
