Product Overview
The TGEC 3-stage telescopic stick features three nested arm sections that slide in and out to deliver maximum reach beyond what a standard or two-stage arm can achieve. This configuration is designed for deep excavation, slope work, forestry log handling, and steep-terrain material handling where operators must reach across steep grades or deep cuts. Often referred to as a three-section log arm or 3-segment forestry boom, it is well suited to timber extraction, log loading, and material movement in remote mountain terrain. Four models are available for excavators from 30 to 60 tons, with extended stick lengths from 14 to 22 meters (maximum working reach from 16 to 24.5 meters). This unit is part of the TGEC excavator boom and arm assemblies lineup.

Series-Wide Technical Highlights
Three telescoping sections provide extended stick lengths from 14 to 22 meters, with maximum working reach from 16 to 24.5 meters depending on model.
Retracted lengths are kept between 6.5 and 9.5 meters, supporting practical road transport subject to local height, weight and permitting requirements.
Constructed from high-strength steel with wear-resistant slide guides and bushings at each telescoping joint for long-term reliability.
Well-suited for deep excavation, forestry log handling, steep-slope material handling, and mountain terrain work where long reach across difficult ground is essential.
Mounting brackets are custom-fabricated for each excavator make and model, with pin spacing and diameters precisely verified.
Excavator Compatibility Guidance
TGEC 3-stage telescopic sticks are offered in four sizes for excavators from 30 to 60 tons. TG-TS30 is configured for 30–35 ton excavators; TG-TS40 for 40–45 ton excavators; TG-TS50 for 50–55 ton excavators; and TG-TS60 for 55–60 ton excavators. The mounting interface is configured to match the specified excavator make and model. Because the extended arm increases leverage, bucket capacity must be reduced relative to a standard arm configuration—match it to the model specifications. When ordering, include the excavator make and model, operating weight, pin-to-pin spacing, pin diameter, and stick width, and the technical team will complete the configuration review.
Typical Applications
Deep excavation: Dig deep foundations, basements, and underground structures where a standard arm won't reach.
Forestry log handling: Extract, lift, and load timber in forestry operations using the three-section log arm to reach across rugged terrain.
Mountain-pulling and slope work: Reach across steep hillsides and mountain slopes for material handling and clearing vegetation.
Marine and waterfront work: Handle underwater excavation, channel dredging, and shoreline jobs that demand extended reach.
Long-distance material handling: Span wide excavations, barriers, or waterways to place or retrieve materials.
Working Principle
The 3-stage telescopic stick uses three nested arm sections that extend and retract via hydraulic cylinders. Each section slides inside the one before it: the outer section connects to the boom, the middle section moves within the outer, and the inner section moves within the middle. The bucket or attachment mounts to the end of the innermost section. When fully extended, the three sections combine to a stick length of 14 to 22 meters (depending on the model), delivering a maximum working reach of 16 to 24.5 meters when mounted on the carrier boom. When retracted, the sections nest together to a compact length of 6.5 to 9.5 meters for transport. The sliding surfaces are fitted with wear-resistant guides and bushings to support alignment during extension and retraction. Because the extended arm increases leverage, bucket capacity should be selected according to the specific model, excavator stability, and working conditions.
