CONSTRUCTION: EXCAVATORS

HITACHI EX1200-6

By Pierre Sanson

H itachi focuses on building excava- tors, not every other kind of machine. The results are, more reliability and higher productivity. Hitachi has a rock-solid reputation as they can lay claim to the conception that over one third of all the hydraulic excavators op- erating throughout the world are Hitachi. All their excavators such as the EX1200-6 are engineered to give the flexibility to handle many different jobs. As a total package the customer gets stronger horsepower, effi- cient engines, comfortable cabs, advanced hydraulics, tough frame and powerful arm and bucket digging forces. With the EX1200-6 the advanced hydrau- lic system provides, combined bucket tilt, boom raise and fast pass speeds which de- livers quicker loading times. In addition, the EX1200-6 has a stronger boom and bigger bucket for increased lift capacity and the smoothest precise operation.

bending and twisting forces and provides strength and balance to handle heavy dig- ging jobs and mated to the heavy duty under- carriage with large diameter swing bearing, provides increased reliability and durability, combined with a high stability factor. The Cummins, 6-cylinder, EPA Tier 2, eco friendly diesel engine adds to the produc- tivity and efficiency of the EX1200-6. With 567 kW (750 hp) on tap, combined with a 3468 Nm of torque, the Cummins engine provides this mammoth excavator with the power source to drive the three main vari- able displacement hydraulic pumps and the gear driven pilot pump. The design characteristics of the EX1200- 6 has reduced the service inspection and maintenance times to a minimum. The unit is loaded with time-money saving mainte- nance features like easy-to-check sight gauges and fluid reservoirs, quick-change remote-mounted filters, advanced self-di- agnostic and extended filter replacement intervals. b

switchable power modes, adjustable for ev- ery job. The power modes include a deep- end mode that gives you the muscle to get the heaviest jobs done and a fuel saving mode for less heavy jobs, which significantly reduces fuel costs. The EX1200-6 also raises productivity with an exclusive auto-level crowd mechanism that allows for easy one-lever crowding of the bucket into the material at a constant level. The well insulated pressurized cab ensures operator comfort under all conditions thanks to the highly efficient heating/air conditioner system. Being a particularly large and roomy cab, operators of various sizes can be ac- commodated without any discomfort. The EX1200-6 is built with uptime in mind. Features such as heavy duty rigging struc- tures and reliable hydraulic, electrical un- dercarriage components.
