IN Brief:
- Takeuchi has introduced two new crawler excavators in the 15 tonne class.
- The TB3150 uses an offset boom, while the TB3150R provides a reduced tail swing configuration.
- Both models add electrohydraulic controls, expanded camera coverage, and redesigned operator environments.
Takeuchi has expanded its crawler excavator range with the TB3150 and TB3150R, giving operators a choice between offset boom and reduced tail swing configurations in the 15 tonne class.
The TB3150 uses an offset boom that allows the machine to excavate close to walls, boundaries, and existing structures without repeatedly repositioning the undercarriage. The arrangement is aimed at utilities, drainage, roadworks, and precision excavation in restricted working areas.
Using a fixed boom and reduced rear overhang, the TB3150R is better suited to urban sites, carriageways, and projects where the machine must operate within a narrow envelope. An optional two piece boom provides additional flexibility for lifting, deep excavation, and working around obstacles.
Both models are powered by an 85kW Yanmar engine and use electrohydraulic controls. Operators can adjust machine response and auxiliary functions through the control system, allowing the excavators to be configured for different attachments and ground conditions.
The redesigned cab includes automatic climate control, a heated air suspension seat, keyless starting through PIN or RFID access, and an eight inch touchscreen display. A jog dial provides access to machine settings without requiring the operator to reach repeatedly towards the screen.
Camera coverage extends around 270 degrees, improving visibility of the machine’s working area and blind spots. The feature is intended to support safer movement where operatives, vehicles, temporary works, and materials may be close to the excavator.
Together, the two machines give fleet owners a choice within a size class widely used for utility work, medium civil engineering packages, housing infrastructure, commercial groundworks, and smaller quarrying or materials applications.
Machine configuration becomes more site specific
The distinction between the models reflects the varied conditions in which excavators are expected to operate. Conventional machines provide stability and familiar geometry, while urban projects frequently restrict tail swing, slewing area, and access for repositioning.
Reduced tail machines can lower the risk of the counterweight entering a traffic lane or striking an adjacent structure. Their more tightly packaged design and different weight distribution make lift planning and operator familiarity particularly important near the edge of the working range.
An offset boom addresses another constraint by allowing excavation beside obstacles while the tracks remain aligned with the working corridor. The arrangement can improve productivity in utility trenches or alongside buildings, although the additional joints and hydraulic components require careful inspection and maintenance.
Electrohydraulic controls are becoming common across more excavator classes because they allow manufacturers to tune behaviour through software. The same architecture can support attachment settings, operator profiles, assistance functions, movement limits, and future automated features.
Recent machinery development has shown how quickly those systems are progressing. Smart excavators demonstrated by Develon at Hillhead added functions designed to guide grading, manage operating limits, and improve visibility.
Takeuchi’s latest models place less emphasis on autonomous operation, although their electronic controls provide a platform for increasingly connected functions. Fleet owners will expect those systems to improve productivity without making diagnosis and maintenance unnecessarily complex.
Camera systems respond to a persistent site risk because excavators routinely work in areas shared with banksmen, groundworkers, delivery vehicles, and other plant. Better visibility can reduce blind spots, but it cannot replace exclusion zones, communication procedures, competent supervision, and planned movement routes.
For plant hire companies, the choice between configurations creates a fleet management decision. A reduced tail model may attract greater demand from city projects, while the offset boom machine could suit utilities and contractors requiring precise excavation beside existing assets.
Utilisation will depend on matching each machine to the correct work rather than treating both as interchangeable excavators. Attachment compatibility, transport dimensions, lifting duties, ground pressure, digging geometry, and operator preference will all influence selection.
Operator comfort also affects productivity and safety during long shifts. Climate control, seat quality, accessible controls, and reduced reaching can limit fatigue, while PIN or RFID access gives fleet managers greater control over authorised use.
Electronic controls and camera systems add capability while increasing reliance on sensors, wiring, software, and diagnostic support. Dealers and hire fleets will need technicians able to identify faults accurately without replacing components unnecessarily.
The TB3150 and TB3150R expand Takeuchi’s reach into a class where contractors expect compact dimensions without sacrificing the output needed for substantial excavation. Offering two distinct geometries recognises that constrained sites present different problems, with some requiring reduced rear swing and others demanding greater flexibility at the boom.
