Powered by the 68.6kW Kubota V3800-DI-T-E3 Stage IIIA diesel engine, the T770 claims a significant increase in power, hydraulic performance and productivity. With an operating weight of 4683kg, the T770 has a rated operating capacity of 1611kg and a tipping load of 4602kg.
Bobcat has increased the standard hydraulic flow on the T770 by more than 30% to 87.1 litres/min to improve attachment performance. High flow hydraulic power has been optimized by ensuring that peak flow occurs close to the rated engine load, providing better fuel efficiency and engine cooling. The higher hydraulic performance also results in faster cycle times with an 18% faster dump/rollback cycle.
The standard maximum travel speed of the T770 is 10.6 km/h, but this can be increased to 17.2 km/h using an optional two-speed system. Traction has been increased by 15 to 20% to provide greater pushing and digging power. A larger fuel tank allows for longer work intervals between refuelling.
Innovations include the Premium Cab design, with more space and improved sound insulation. Bobcat says that the ergonomics are also improved for greater operator comfort, enhanced productivity and better protection both back and front. The cab has also been moved further forwards to improve visibility for the operator both in front and all round the machine.
Bobcat will also have its recently launched S630 and S850 skid-steer loaders and the T650 and T870 compact tracked loaders on show in Las Vegas. The stand will also have the new E45 and E50 zero tail swing (ZTS) models. Based on the same platform, the E45 and E50 are in the 4t-6t mini-excavator category.
Equipped with cab and bucket, the E45 has an operating weight of 4634kg and offers a maximum digging depth of 3300mm. The E50 model, equipped with cab and bucket, has an operating weight of 4905kg and a maximum digging depth of 3524mm.
They are powered by the 4-cylinder Kubota V2403-M-DI-TE38-BC-5 and V2403-M-DI-TE38-BC-4 turbo-charged Tier III diesel engines, respectively. The E45 has breakout forces of 28.0kN in the dipper arm and 35.1kN at the bucket, while the E50 offers 30.4kN in the dipper arm and 41.2kN at the bucket. Lifting capacities are 2369kg and 2778kg, respectively.
