Conexpo 2011 will see the North American launch of the first representative of Sandvikâ€™s new generation down-the-hole drill rigs, the Sandvik DI550. The new machine offers unique productivity and user comfort in 5â€ť hammer drilling.
Businesses, large and medium sized quarries and contractors in particular, constantly need to improve the productivity of their operations. This means that it is of great importance to choose machines that do exactly the job they are supposed to – no more, no less. The new Sandvik DI550 is the machine that meets these criteria. It is a down-the-hole drilling rig with features a 324 kW diesel engine and a 24.4 m3 compressor air flow at 24 bar pressure â€“ making the machine a perfect match for the 5â€ť DTH hammer. This careful match of power and hammer size makes the rig productive, whilst keeping fuel consumption and operating costs as low as possible. Cost effective machine performance is further enhanced by other advanced features such as active diesel RPM control, optimized diesel RPM level during drilling and active control of compressor running temperature.
On top of high performance, simple and comfortable machine operation was in focus during product development. Featuring a modern, accurate control system with simple icon displays and comprehensive service information, the new DI550 thus enables seamless co-operation of man and machine. The rigâ€™s modern, over-pressurized ROPS and FOPS certified cab with its advanced ergonomic, efficient air conditioning, and excellent visibility, further add to the operator comfort. The large windshield comes with a strong safety bar that is easy to open for cleaning.
The new, efficient dust collector with non-stop cleaning decreases the amount of dust emissions to the environment. It also improves filter lifetime and, therefore, reduces the need for maintenance.
Other features that translate into easy maintenance and thus low downtime include the engine compartmentâ€™s open layout, easy cooler cleaning, modular compressor control system and simplified electric system. All daily maintenance points are located on the ground level to simplify the process and improve safety of service personnel. A fast fuel filling option and large fuel tank further cut costly downtime.
