Product Overview

The TGEC two-piece demolition front is built around an articulating boom joint that lets the boom fold at a secondary pivot point — providing variable working height and attachment positioning flexibility through the articulated joint, while remaining more compact than a dedicated high-reach demolition rig. This variable-angle (VA) boom design allows the operator to adjust working height and attachment positioning for a wide range of demolition tasks. Eight models cover machines from 6 to 50 tons, with lift heights ranging from 9.1 meters on the compact TG-DB06-8 up to 21.6 meters on the top-end TG-DB50. As part of the TGEC excavator boom and arm assemblies family, this configuration is designed for mid-height building demolition, interior structural tear-out, and job sites where a full high-reach demolition configuration may not be necessary. For a deeper look at boom configurations and how the pieces fit together, check out our excavator boom types guide and boom vs arm vs stick comparison.

Typical Applications

  • Mid-rise demolition: Take down low- to mid-rise buildings, warehouses, and industrial structures from the top down.

  • Interior structural removal: Remove interior walls, floors, and columns where exterior access is tight.

  • Concrete breaking and pulverizing: Break and process concrete slabs, beams, and columns at medium working heights using compatible hydraulic attachments.

  • Bridge and overpass work: Remove decks, parapets, and approach sections at accessible heights.

  • Plant dismantling: Dismantle process vessels, pipe racks, and structural steel in industrial facilities.

Working Principle

The boom and arm functions use the excavator's hydraulic system — the main boom cylinder controls the lower section, while a second cylinder manages the articulating joint up top. That variable-angle joint lets the operator fold or reposition the upper boom section, adjusting working height and reach without having to reposition the whole machine. The articulated configuration provides more positioning flexibility than a fixed mono boom, particularly when working around obstacles or at varying working heights. A breaker, pulverizer, or shear mounts at the arm end and is powered through the auxiliary hydraulic circuit. Certain models include a counterweight system configured for the specified machine and working geometry, and the boom sections can be folded for transport, reducing the overall transport height.

Frequently Asked Questions

What is a two-piece demolition front used for?+

A two-piece demolition front, also known as a variable angle boom or VA boom, is a boom configuration with an articulated joint that allows the boom to fold and reposition, providing variable working height and attachment positioning that a fixed mono boom cannot achieve. It is used for medium-height building demolition, interior structural removal, concrete breaking and industrial plant dismantling where a standard boom cannot reach but a full high reach boom may not be necessary. The variable angle joint allows the operator to work around obstacles and position the attachment at appropriate angles for demolition work.

What is a two-piece excavator boom configuration?+

A two-piece excavator boom configuration consists of a main boom section and a second articulated boom section connected by a pivot joint, with a hydraulic cylinder controlling the angle between the two sections. This design allows the boom to fold and extend, providing variable working height and reach that a standard one-piece mono boom cannot achieve. The two-piece design is more compact than a full three-section high reach boom while still providing extended reach for demolition work. It is sometimes called a variable angle boom, VA boom, or double boom excavator.

When is a two-piece demolition front preferred?+

A two-piece demolition front is preferred for medium-height demolition work where a standard boom cannot reach but a full high reach boom may not be necessary. It is designed for low-rise and mid-rise building demolition, interior structural removal where the variable angle allows work around obstacles, bridge and overpass work, and industrial plant dismantling. The two-piece design provides greater flexibility than a mono boom while remaining more compact and transportable than a full high reach configuration. It is also preferred for contractors who need extended reach for demolition but also want to use the machine for general excavation work.

What excavator information is required for matching?+

To match a two-piece demolition front to your excavator, provide the excavator make and model, operating weight, pin-to-pin spacing at the boom foot and arm connection, pin diameter, stick width, auxiliary hydraulic flow and pressure, and the intended demolition attachment specifications. Also specify the maximum required working height for the application. This information allows the engineering team to verify the mounting bracket geometry, confirm the correct model size, specify the required counterweight if applicable, and ensure the hydraulic system can power the attachment. If the excavator uses a quick coupler, provide the coupler brand and model as well.

Can the two-piece configuration be customized?+

Yes. TGEC engineers custom two-piece demolition fronts for specific excavator makes and models, including major excavator brands, subject to machine and mounting-data verification. Custom modifications may include alternative boom section lengths, modified arm configurations, adjusted counterweight systems, or specialized attachment mounts. Custom paint colors, branding and packaging are available through the OEM program. Provide the excavator details and application requirements, and our engineering team will produce custom fabrication drawings for approval before production begins.

What demolition attachments can be mounted to the front?+

The two-piece demolition front can accommodate hydraulic breakers, concrete pulverizers and demolition shears, depending on the model size and excavator hydraulic capacity. Hydraulic breakers are used for concrete breaking and structural demolition, pulverizers crush concrete and separate it from rebar, and shears cut through steel beams and structural steel. The attachment must be compatible with the excavator auxiliary hydraulic flow and pressure, and the breaker rod diameter must match the attachment specification. Consult the TGEC engineering team for specific attachment compatibility for each model.

How does a two-piece configuration affect working geometry?+

A two-piece configuration significantly changes the excavator working geometry compared to a standard mono boom. The articulated joint allows the boom to fold and extend, providing variable working height from 9.1 to 21.6 meters depending on the model. The articulated configuration changes the working envelope, allowing the operator to adjust working height and attachment position according to the boom angle. The variable angle allows the operator to position the attachment at appropriate angles for demolition work, including working vertically against building facades or horizontally under overhead structures. The transport geometry is designed to fold the boom sections into a more compact transport configuration.

Can TianGe manufacture OEM two-piece demolition fronts?+

Yes. OEM and private-label production is available for excavator two-piece demolition fronts and variable angle booms, with custom paint colors, logo placement, packaging and documentation. Custom mounting brackets and counterweight systems can be configured for the excavator brands common in your target market. Supply arrangements can be discussed based on project requirements, target market and order volume. Contact the sales team with your company details, target market and estimated volume for a customized OEM proposal.

What dimensions are required for replacement production?+

For replacement two-piece demolition front production, provide the excavator make and model, operating weight, pin-to-pin spacing at the boom foot and arm connection, pin diameter, stick width, and the current boom and arm dimensions if available. If the original assembly was a TGEC unit, provide the original model number and serial number. For non-TGEC replacements, provide as much dimension information as possible, including the boom section lengths, arm length, pivot spacing and bucket linkage geometry. Our engineering team will verify the dimensions and produce custom fabrication drawings for approval before production begins.

What should dealers confirm before ordering?+

Dealers should confirm the target excavator makes and models common in their market, the typical operating weight range, available pin dimensions for each machine model, the primary demolition applications their customers work on, the typical attachment types used (breakers, pulverizers, shears), and the expected order volume. Confirm whether customers require pin-on or quick-coupler mounting configurations. Specify any custom branding, paint color or packaging requirements. Dealers should also understand the transport dimensions, counterweight requirements and shipping arrangements for each model size. Contact the TGEC dealer sales team with this information to set up a wholesale account and receive volume pricing.

What information should contractors provide for a quotation?+

Contractors should provide the excavator make and model, operating weight, pin-to-pin spacing, pin diameter, stick width, auxiliary hydraulic flow and pressure, preferred model (TG-DB06-8 through TG-DB50), intended demolition attachment (breaker, pulverizer, shear), primary application, maximum required working height, mounting or coupler type, and the quantity required. If you are unsure which model fits your excavator, include the machine details and project height requirements, and our technical team can recommend the optimal configuration.
