Takeuchi 15t excavators: design, control and visibility upgrades for site engineers

30 Second Briefing
Takeuchi has introduced two 15‑tonne 3‑Series excavators, the offset boom TB3150 and reduced tail swing TB3150R, both powered by an 85kW (114hp) Yanmar engine and upgraded hydraulic horsepower for multi‑function operation. The TB3150’s boom swing system enables offset digging without repositioning the tracks, while the TB3150R’s reinforced fixed boom, minimal rear overhang and optional two‑piece boom target confined or structure‑adjacent work. A redesigned cab adds an 8in touch screen, 270° camera coverage, pilot joysticks, electro‑hydraulic travel and blade controls, and keyless RFID/pin security.
Technical Brief
- TB3150R’s reinforced fixed boom is configured to minimise rear overhang for structure-adjacent excavation.
- Optional two-piece boom on TB3150R extends reach flexibility for lifting at varying stand-off distances.
- Offset digging on TB3150 reduces track repositioning cycles, improving productivity in narrow utility corridors.
- Increased hydraulic horsepower is tuned for simultaneous multi-functioning, e.g. combined swing, boom and auxiliary tool use.
- Pilot-operated joysticks are paired with electro-hydraulic travel, dozer blade and boom swing for finer modulation.
- Cab upgrades include automatic climate control and a heated air-suspension seat for long-shift operator endurance.
- Keyless start with PIN and RFID reduces theft risk on dispersed civil and utility sites.
- 270° camera coverage and 8in touch display support safer trench-edge operation and blind-side manoeuvring.
Our Take
Takeuchi’s move into the 15t class in the United Kingdom comes as our database shows it more often appearing in dealer and distribution stories (such as the MSM/DRH–Merlo UK agreement) than in core machine launches, signalling a push to rebalance towards higher-spec product visibility.
The use of an 85kW Yanmar engine aligns with Yanmar’s parallel expansion in compact and mid-size equipment lines (SV10 mini excavator, compact track loaders, tracked carriers), suggesting contractors could benefit from parts and service commonality across mixed Yanmar-powered fleets.
