Telescopic Arm with Brush Cutter for Rail Excavators used in vegetation management

Vegetation clearance on slopes, waterside zones along railway, highway and photovoltaic sites has long been a tough challenge. Steep and narrow terrain is inaccessible for workers, while conventional attachments suffer from limited working reach and low efficiency. The TNSB85 telescopic arm brush cutter, developed by Shandong Tiannuo Machinery, is purpose-built for 7.5–9 ton road‑rail excavators, delivering reliable long‑distance mechanical clearing with superior technical performance.

Equipped with a 3‑stage synchronized telescopic boom, this attachment reaches a standard total length of 6 meters, with customizable extension travel. Driven hydraulically, it delivers smooth and precise boom movement. Built‑in hydraulic lines avoid exposed hoses, lowering risks of collision and abrasion, perfectly matching the tight time window of railway maintenance during track possession.

Fitted with a heavy‑duty brush cutting head, it features 24 durable flail blades running at a speed over 2200 r/min. It only requires an oil flow of 20 L/min for operation. The cutting roller has a working width up to 1000 mm and can shred branches with a maximum diameter of 200 mm. The front attachment weighs 484 kg with well‑balanced counterweight for stable cutting. Its compact dimension of 1423×600×903 mm enables easy transportation and positioning along rail tracks.

This versatile machine serves multiple applications: railway slope maintenance, highway slope trimming, river and canal vegetation removal, fire prevention weeding for power and photovoltaic corridors, as well as low shrub trimming on hillsides and woodland. Thanks to the extended telescopic boom, it safely handles hazardous steep slopes and waterside areas without manual entry, greatly reducing safety risks. Mounted on a rail excavator, it efficiently removes overgrown vegetation intruding the railway clearance, securing sightlines and lowering fire hazards.

Compared with manual clearing and fixed‑arm cutters, it combines far reach and powerful shredding capacity. Robust blades and proven hydraulic construction withstand harsh outdoor conditions. Customizable boom length is available to meet different project demands for railway maintenance, water conservancy and new energy sectors, cutting labour costs and boosting vegetation management productivity.
