Komatsu WB70A-1

Features

• 3 MACHINES IN 1
  The WB70A-1 is the successful combination of three specific models in a single machine: BACKHOE LOADER, WHEELED LOADER, TOOL CARRIER. In fact, based on needs, the WB70A-1 can be transformed into a specific machine for digging, loading or construction site operations. Thanks to the use of the front hydraulic quick coupler, available on request, any kind of equipment can be connected in just a few seconds without having to vary the digging forces while using the loader.
  
• Transmission
  The hydrostatic transmission offers many advantages: continuous and constant traction, braking effect on slopes, operations carried out on wheels only without stabilizers and travel speed control that doesn’t depend on engine rpm (thanks to the inch pedal). Besides these features, the WB70A-1 today offers one of the highest speeds in its category. The main characteristic of this model is the ± 40° central articulation, which, together with the 20° total oscillation of the frames (that can be locked from the cab), make the WB70A-1 unbeatable in terms of stability and adaptability to even the most irregular surfaces, thus allowing the load to be transported smoothly and safely under all operating conditions.
  
• Excellent performance and high productivity
  The "High-Flow" hydraulic system, the backhoe that’s the end result of 35 years of experience, the front loader with "Z" kinematic motion and a sturdy structure put the WB70A-1 at the top of its category for any type of performance. Engine power and digging forces make this machine a champion of productivity. Since the machine can operate with the front loader always aligned with the front wheels (a specific feature of wheeled loaders), greater thrusting forces are generated during loading along with higher stability during steering with no loader torsion.
  
• Comfortable and environmentally-friendly
  The ROPS and FOPS cab is roomy and comfortable, thanks to the efficient positioning of the controls, while excellent visibility is guaranteed by the wide glazed surfaces, the central position of the engine and the special configuration of the articulation. Ergonomic controls and reduced noise levels inside and outside the cab, together with the ventilation system with intake air filtering, provide the operator with a truly comfortable environment.
  
• Versatility
  Thanks to the exclusive KOMATSU coupling/uncoupling system, the operator can release the entire backhoe unit simply by moving a lever and disconnecting 2 pipes supplied with a rapid coupler. Therefore, the even more compact dimensions and improved manoeuvrability make the WB70A the best choice for working in limited spaces. A counterweight to increase machine stability is available upon request.
  
• Maintenance
  Owing to the position of the inspection points and the particularly safety-conscious overall design, the few routine maintenance operations required can be carried out without using special tools, while reducing time and costs and enhancing machine reliability at the same time.
