Takeuchi TB3150 Offset Boom Excavator Now Available in the UK

The Takeuchi TB3150 is a new 15-tonne class excavator with an offset boom, and Takeuchi UK confirmed on 15 October 2026 that it is now available in the UK. It runs a new 85 kW (114 hp) Yanmar engine, and Takeuchi says it has more than 14% more hydraulic horsepower than the model it replaces. It sits alongside the fixed-boom TB3150R, which arrived in the UK earlier in the summer, so buyers now have two choices of Takeuchi TB3150 in this weight class.

What Takeuchi has announced

In its UK news release, Takeuchi says the TB3150 brings its offset boom system into the 15-tonne class with a step up in hydraulic performance. The machine was first shown with its sister model ahead of Hillhead in June 2026, and the offset version is now on sale here. Takeuchi also says the first TB3150 machines are about to start work on HS2.

The two models replace the previous TB2150 and TB2150R. Takeuchi is best known in the UK for its mini excavators, but it has built larger 12 to 15 tonne machines for more than twenty years, and the offset boom has long been one of the features that sets its excavators apart.

Takeuchi TB3150 vs TB3150R: offset or fixed boom

Both machines share the same platform, engine and cab, but they are built for different ways of working.

• TB3150 (offset boom): the boom can swing to the side, so the operator can dig offset from the tracks without moving the whole machine. It uses a conventional tail swing.
• TB3150R (fixed boom): a reduced tail swing design with a reinforced fixed boom. Less rear overhang means the operator can work closer to walls, structures and traffic. Takeuchi also lists an optional 2-piece boom for extra flexibility when lifting and working at different distances.

In simple terms, the TB3150 is aimed at jobs where you need to dig alongside the machine, and the TB3150R is aimed at jobs where you need to keep the back end tucked in.

Why an offset boom matters on a 15-tonne machine

Takeuchi describes the offset boom as unusual in this weight class. Being able to dig to one side without tracking the machine round is handy for:

• Utility trenches along roads and pavements, where the machine can sit in one lane and dig beside it.
• Work tight to fences, buildings or boundaries.
• Sites where repeatedly moving a tracked machine would cut up the ground or get in the way of other trades.
• Jobs that need accurate positioning of the bucket without shuffling back and forth.

Engine, hydraulics and cooling

Both 15-tonne models use a new Yanmar engine rated at 85 kW (114 hp). Takeuchi says a lot of engineering went into redesigning the cooling system, and that this is what allowed the rise of more than 14% in hydraulic horsepower over the previous model. According to Takeuchi UK’s product manager, operators using the machine have said it feels more powerful in demanding work.

More hydraulic power is most noticeable when the machine is doing several things at once, such as slewing, lifting and crowding the bucket in one movement, or when running hydraulic attachments.

Inside the cab

The TB3150 and TB3150R get Takeuchi’s latest 3-Series cab. Takeuchi lists:

• Automatic climate control and a heated air suspension seat.
• Keyless start using a PIN code or RFID, which helps control who can use the machine.
• An 8-inch touchscreen display with a jog dial and a multi-switch control panel.
• 270-degree camera views around the machine.
• Pilot-operated joysticks, with electro-hydraulic controls for travel, the dozer blade and boom offset.

What this means for buyers of used excavators

Takeuchi has not published UK prices for the new machines, so speak to a Takeuchi dealer if you want a new quote. If you are weighing up new against used, a few points are worth thinking about:

• Older TB2150 models: as fleets move to the TB3150, more of the outgoing TB2150 and TB2150R machines may come up for sale second hand. Check hours, service history, the boom swing pins and bushes, and the condition of the tracks and undercarriage.
• Offset or zero tail: decide which suits your work before you shop. An offset machine and a reduced tail swing machine of the same weight are not like for like.
• Smaller Takeuchi machines: if 15 tonnes is more than you need, Takeuchi midi and mini diggers are common on the used market.
