EXCAVATOR: Hitachi’s new EX3600-7 offers more efficiency, reliability, durability



The new Hitachi EX3600-7 is rigged with intelligent features to minimize downtime.

ILLINOIS – Hitachi unveiled the EX3600-7 mining excavator, which delivers increased efficiency, reliability and durability for customers in North and South America. The new model is the fourth machine in Hitachi’s new EX-7 Series lineup, following the recent launch of the EX5600-7, EX2600-7 and EX1200-7.

“The EX3600-7 sets a new standard in the mining industry,” said Brian Mace, mining product marketing and applications manager, Hitachi Construction Machinery Americas. “With a multitude of innovative features, it’s a reliable [workhorse] that is ready for its tough job. A variety of new features reduce its fuel consumption, increase its efficiency and make maintenance even simpler.”

Maximized efficiency

Available in a backhoe or shovel configuration, the new EX3600-7 features fuel consumption optimization (FCO) technologies that reduce consumption costs while achieving superior productivity and enhancing sustainability. Customers can choose a Cummins or MTU EPA Final Tier 4 engine option and hydraulic system improvements that reduce fuel consumption by 4% to 7% compared to the previous model (the EX3600-6 with Cummins engine configuration).

Other new features that enhance efficiency include: individually controlled hydraulic

Improved reliability

The EX3600-7 is loaded with intelligent features to minimize downtime and optimize machine longevity. A new auto-lubrication system with a large capacity grease tank, new grease pump, in-line grease filter with breather and grease level indicator in the cab helps reduce downtime.

A larger hydraulic oil cooler with variable speed reduces energy demand to create a more reliable hydraulic system and effectively reduce temperatures to improve maintainability.   Likewise, the cab riser now features a pressurizer system to reduce dust infiltration and extend the service life of electronic components within.

Additional new features that increase reliability include: reduced cylinder pump flow rate; rearranged hydraulic hoses; self-lubricating centre joint; and a removable major wire connections.

Reinforced durability

The EX3600-7 design was created for optimal durability to withstand tough jobs and menacing terrains. The mainframe is now stronger than previous models because stress is more evenly dispersed across the sturdy, slanted frame. This exclusive center track frame delivers optimal stress dispersion through specially designed forged steel parts that reduce the chance of failure in critical high-stress areas.

More new features that boost durability include: a lubrication piping cover on the swing bearing; three double-sided, pedestal designed upper rollers on each side of the track frame; solid conduit that protects wires; and patented track shoes with Hitachi’s unique hardening process.

Enhanced comfort and safety

The EX3600-7 increases provides maximum cab comfort and safety for operators with a pressurized cab, air conditioning, and a seat that automatically adjusts the suspension to the operator’s weight. More new features and options that contribute to safety include: an on-board inclinometer with two levels of alerts; anti-slip walkways; improved handrails; and Aerial Angle, a 360° vision system.

The EX3600-7 also features connection to Hitachi’s Global e-Service. This online machine management system provides access to each on-site machine from a PC. With on-board sensors, diagnostic tools, real-time data and intelligent software, the EX3600-7 can reach its full potential.

The EX3600-7 will be available to those in the United States, Canada, Latin America and Brazil. The machine is also available as an electric powered shovel in the United States and Latin America. Hitachi’s EX-7 Series excavators are manufactured in Japan.
