Bobcat adds 700 Series loaders

The 700 Series comprises a new skid-steer loader model, the S770, a new compact tracked loader, the T770, and a new all-wheel-steer (AWS) loader, the A770. The 700 Series loaders are part of a new large frame platform that fits between the extended medium (600 Series) and extended large frame loaders (800 Series) introduced in 2010. 

Powered by the 68.6 kW Kubota V3800-DI-T-E3 diesel engine with a rated speed (SAE JI 995 Gross) of 2400 RPM, the S770, T770 and A770 replace the S300/S330, T300/T320 and A300 models, respectively. All three of the new loaders offer higher rated operating capacities and increased engine and hydraulic power.  

The S770 loader has an operating weight of 4162kg, a rated operating capacity of 1569kg and a tipping load of 3137kg. 

The rated operating capacity and tipping load for the T770 compact tracked loader are 1611kg and 4602kg, respectively. The T770 loader has an operating weight of 4683kg.

The A770 AWS loader has an operating weight of 4291kg, a rated operating capacity of 1550kg and a tipping load of 3100kg.

As well as higher performance and power, the 700 Series loaders offer improved visibility, comfort and uptime protection, Bobcat says.  All three models have a height of 2065mm, a length with bucket of 3597mm and a bucket hinge pin height of 3353mm.  The S770 and A770 have a width without bucket of 1832mm, compared to a width over the tracks for the T770 of 1981mm. 

They all have the new Premium Cab, which has the following features:

• A new forward position that offers a 30% increase in all-round visibility for the operator
• Forward visibility improved by the 45% larger glass pane in door
• Visibility through top, side and rear windows all significantly enhanced
• 50% increase in the output from the front working lights
• Ample adjustment in seat and suspension to suit individual preference
• Adjustable SJC joysticks integrated on the seat arms
• Pressurised cab improving HVAC performance by 35%
• Improved hydraulic smoothness thanks to new cushions in the lift cylinders
• Radio ready, 12 V power outlet option for charging mobile phone/MP3 player/iPod
• Cup holder and additional storage compartments
• New full-colour deluxe instrumentation panel option

 Other improvements include:

• Traction is increased by 15 to 20% to provide greater pushing and digging power.
• The standard flow hydraulic efficiency has been increased by over 30%, providing better attachment performance. Hydraulic flow has been increased by 11% or 9 l/min. The pressure of the pumps has been increased by almost 14 bar, while back pressure of the hydraulic system has been reduced by 7 bar.
• Higher hydraulic performance results in faster cycle times with an 18% faster dump/rollback cycle. 
• Optional high flow hydraulic power (151 l/min) has been optimised by ensuring that peak flow occurs close to the rated engine load, providing better fuel efficiency and engine cooling.
• A larger double fuel tank allows for longer work intervals between refuelling.
• The cooling package is the same as on the new larger S850 and T870 loaders. Cooling capabilities are increased thanks to a larger cooling fan and a more efficient design of the fan shroud, which is made entirely of aluminium to ensure the best heat rejection and improved corrosion resistance. The screen has thinner fins, similar to lawn mowers. 

 The hydraulic quick coupler block is integrated and protected in the lift arm.  An integrated rear bumper protects the tailgate. The 700 Series loaders offer excellent serviceability with an easily accessible box-style air filter, a transversely mounted engine and swing-open tailgate. A swing-up oil cooler allows fast and easy cleaning of the oil cooler and radiator. Hydraulic oil filtration down to 10 microns significantly reduces the possibility of contamination.
