Product Overview
The TGEC excavator high reach demolition boom is a purpose-built replacement for standard booms, offering extended reach for bringing down tall buildings, dismantling high-rise structures, and breaking concrete at elevation. Its multi-section design pushes the maximum working height from 14.9 meters on the compact TG-UHD25 all the way up to 23.1 meters on the TG-UHD45, giving operators access to upper stories and elevated structural elements that would otherwise be out of reach. Each configuration includes a counterweight package specified for the corresponding machine size and boom geometry. This assembly is a core part of the TGEC excavator boom and arm assemblies family, built specifically for demolition contractors, building dismantling specialists, and structural removal experts.

Available Configurations & Models
Five models are offered to cover excavators from 25 to 45 tons. Keep in mind that all dimensions are approximate and may vary slightly depending on the final build and the specific carrier machine.

Series-Wide Technical Highlights
Multi-section extended boom delivers maximum lift heights from 14.9 to 23.1 meters, designed for high-rise demolition and elevated concrete removal.
Model-specific counterweight packages are provided to support the required machine balance for high-reach operation.
The arm end supports an allowable attachment weight of up to 2000 kg, compatible with standard demolition shears, concrete pulverizers, and hydraulic breakers.
Heavy-gauge steel construction with reinforced pivot points and thickened plate sections stands up to the extreme stresses of high-reach demolition.
Transport height is engineered to stay between 3.16 and 3.4 meters, supporting practical road transport subject to local height, weight and permitting requirements.
Excavator Compatibility Guidance
TGEC high reach demolition booms are sized for excavators from 25 to 45 tons in five steps. TG-UHD25 is configured for 25-ton-class excavators, TG-UHD30 for 30-ton excavators, TG-UHD35 for 35-ton-class units, TG-UHD40 for 40-ton models, and TG-UHD45 for 45-ton excavators. Each assembly includes a counterweight package specified for the corresponding excavator class and boom configuration. When ordering, provide the excavator make and model, operating weight, pin-to-pin spacing, pin diameter, stick width, and the demolition shear or attachment you plan to use—the technical team will complete the configuration review.
Typical Applications
High-rise demolition: Bring down tall buildings, towers, and multi-story structures floor by floor using hydraulic shears and concrete crushers.
Elevated concrete breaking: Bust up concrete slabs, beams, and columns at heights that standard booms and breakers can't touch.
Chimney and stack removal: Take down industrial chimneys, smokestacks, silos, and other tall vertical structures.
Bridge and overpass demolition: Remove bridge decks, girders, and overpass sections from an elevated working position.
Industrial plant dismantling: Tear down tall process vessels, pipe racks, and structural steel in industrial settings.
Working Principle
This high reach demolition boom runs off the excavator's standard hydraulic circuits—the boom cylinder handles raising and lowering, while the arm cylinder controls extension and retraction. The multi-section design pushes the working height far beyond what a standard boom can manage, allowing the operator to reach upper levels and elevated structures. A hydraulic demolition shear or concrete pulverizer attaches to the arm end and gets its power from the excavator's auxiliary hydraulic circuit. The counterweight system is specified to support the required machine balance for the extended boom configuration. Final operating stability depends on the excavator, attachment, working radius, ground conditions, and application. For transport, the boom sections are designed to fold or nest so that overall transport height remains within practical road transport dimensions, subject to local regulations.
