Product Overview

The TGEC excavator ripper boom assembly is a dedicated reinforced boom-and-arm configuration designed for severe-duty ripping applications, featuring a ruggedized design to handle high ripper loads. Manufactured from high-tensile steel with strengthened pivot joints and extra-thick plating, it’s built to endure the severe stresses of ripper tooth operation. The integrated ripper, fixed at the arm end, uses the excavator's bucket curl function to loosen rock, caliche, and permafrost through the standard bucket curl circuit rather than a dedicated auxiliary attachment circuit. As a key member of the TGEC excavator boom and arm assemblies family, this unit is ideal for quarrying, highway construction, mining, and major earthmoving jobs where conventional buckets fall short.

Excavator Compatibility Guidance

TGEC ripper boom assemblies are available for 30-to-90-ton excavators in four distinct sizes. Choose the TG-RB30 for 30-ton-class machines, the TG-RB40 for 40-ton excavators, the TG-RB70 for 70-ton-class equipment, and the TG-RB90 for 90-ton models. Each assembly is built to order for the precise make and model, with mounting brackets designed to match the machine's pin dimensions. When you place an order, be sure to include the excavator make and model, operating weight, pin-to-pin spacing, pin diameter, and stick width so our engineering department can confirm the correct mounting configuration. This ripper configuration is designed to use the excavator's bucket curl circuit rather than a dedicated auxiliary attachment circuit.

Typical Applications

  • Quarries and surface mining: Loosen and displace hard rock layers, overburden, and tundra for easier loading.

  • Road building: Penetrate caliche, compacted subgrade, and rocky outcrops during base course prep.

  • Large civil works: Excavate solid ground, shattered rock, and permafrost on heavy civil and footing projects.

  • Demolition and site clearing: Dismantle concrete pads, footings, and stubborn ground during site preparation.

  • Rock trenching and hard-ground excavation: Cut through rock and cemented layers that stop standard buckets, then clear out the spoils.

Working Principle

The ripper tooth is operated through the excavator's bucket curl function. During ripping, the machine applies hydraulic force through the arm and attachment to loosen hard or compacted ground. The boom and arm are constructed from thicker plate with reinforced joints to withstand the loads generated during ripper operation. This configuration uses the excavator's standard bucket curl circuit rather than a dedicated auxiliary attachment circuit.

Frequently Asked Questions

What is an excavator ripper boom assembly used for?+

An excavator ripper boom assembly is a reinforced boom and arm configuration with an integrated ripper tooth, designed to break and loosen hard rock, hardpan, frozen soil and compacted ground that standard buckets cannot penetrate. It is commonly used in quarry work, mining, road construction, heavy civil projects and demolition site preparation. The ripper tooth uses the excavator bucket curl force to break up material without requiring a separate hydraulic breaker.

What type of excavator is suitable for a ripper boom assembly?+

Ripper boom assemblies are designed for medium to large excavators from 30 to 90 tons. The TG-RB30 is intended for 30-ton-class excavators, the TG-RB40 is available for 40-ton machines, the TG-RB70 is configured for 70-ton-class equipment, and the TG-RB90 is intended for 90-ton excavators. The appropriate excavator size depends on the required ripping force, ground conditions and machine configuration. The assembly is configured in place of the standard boom and arm. The ripper configuration is designed to use the excavator's bucket curl circuit rather than a dedicated auxiliary attachment circuit.

What information is needed to match a ripper boom to an excavator?+

To match a ripper boom assembly 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, and the primary application. This information allows the engineering team to verify the mounting bracket geometry, confirm the correct model size, and ensure the assembly fits the machine properly. If the excavator uses a quick coupler, provide the coupler brand and model as well.

Can the ripper boom assembly be customized for different excavator models?+

Yes. TGEC engineers custom mounting brackets for specific excavator makes and models, for specific excavator makes and models, subject to machine and mounting-data verification. The boom foot connection, arm pivot geometry and ripper attachment are configured to match the specific machine. Custom modifications may include reinforced sections, alternative ripper tooth designs, or modified transport dimensions for specific shipping requirements. Provide the excavator details and our engineering team will confirm the custom configuration.

Can the mounting interface be made to match the customer's machine?+

Yes. The mounting interface is custom-engineered to match the customer's specific excavator model, including the boom foot pin spacing, pin diameter, arm pivot geometry and stick width. Mounting configuration can be engineered according to the excavator's connection requirements. When ordering, provide the excavator make and model, operating weight, pin-to-pin spacing, pin diameter and stick width, and the engineering team will supply the correct mounting bracket. If the machine uses a quick coupler, provide the coupler brand and model so the bracket can be configured to match.

What attachments can be used with a ripper boom assembly?+

The primary attachment for a ripper boom assembly is the integrated ripper tooth, which mounts to the arm end in place of the bucket. The ripper tooth is designed for breaking rock, hardpan and frozen soil. Some configurations may allow alternative ripper shank designs or tooth profiles for specific ground conditions. The assembly is not designed to switch back and forth between a ripper and a standard bucket, as the boom and arm are reinforced specifically for ripper applications. Consult the TGEC engineering team for alternative attachment options.

How is a ripper boom different from a standard excavator boom?+

A ripper boom assembly differs from a standard excavator boom in several key ways. The boom and arm are fabricated from thicker, higher-strength steel with reinforced pivot points to withstand the high shock loads generated by ripping. The arm end is configured for a ripper tooth attachment rather than a bucket. The overall geometry may be optimized for ripping force rather than digging reach. Unlike a standard boom, the ripper assembly is designed specifically for hard ground and rock breaking applications and is not intended for general-purpose digging or material handling.

What should dealers confirm before ordering ripper booms?+

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, and the primary applications their customers use ripper booms for. Verify whether customers require pin-on or quick-coupler mounting configurations. Confirm the expected order volume and any custom branding or packaging requirements.
