EH700

Product catalog summary

Overview:
The document provides detailed technical specifications and performance data for the Hitachi Construction Machinery model EH700. It includes information on the vehicle's capabilities, design features, and optional equipment, as well as instructions for interpreting performance charts.

Specifications:
The EH700 is powered by a Cummins QSK19-C525 engine with a rated output of 392 kW (525 hp) at 2100 rpm. It features a turbocharged and aftercooled 4-cycle engine with six cylinders. The transmission is an Allison M5610 planetary type with full automatic shifting, offering six forward speeds and two reverse speeds. The vehicle's electrical system operates on 24 volts, and the body has a struck capacity of 17 m3 and a heap capacity of 23.9 m3.

Weights and Dimensions:
The chassis with hoist weighs 24,591 kg, and the body weighs 7,257 kg, resulting in a net machine weight of 31,848 kg. The maximum gross machine weight is 69,854 kg. The steering system features a 42° steering angle and a turning diameter of 16.15 m.

Systems and Features:
The vehicle includes a hydrostatic power steering system, an all-hydraulic braking system with front dry disc brakes and rear oil-cooled wet disc brakes, and a hydraulic system with a hoist pump output of 301.3 l/m. The Command Cab III features an integral ROPS/FOPS structure and a CONTRONIC II monitoring system.

Construction and Design:
The body is constructed with high tensile strength alloy steel, and the frame is a full fabricated box section with high strength low alloy steel. The ACCU-TRAC suspension system includes independent trailing arms and NEOCON struts.

Service Capacities:
The vehicle has a fuel tank capacity of 454.2 liters, with various other fluid capacities for the crankcase, transmission, cooling system, and hydraulics.

Optional Equipment:
Options include air suspension seats, body liners, and additional safety and performance features.

Procedures:
Instructions are provided for using performance and retarder charts, guiding users to determine machine speed based on total resistance and weight lines.

Key Data:
Charts are based on 0% rolling resistance, standard tires, and gearing, with diagonal lines representing total resistance.

Full fabricated box section main rails with section height tapered from rear to front. Wider at the rear to support the loads and narrower at the front to allow for engine accessibility. One piece top and bottom flanges that eliminate cross member tie in joints and provide a large exposed center area for access to major components. Large radii at frame junctions are blended and ground to minimize stress concentrations. Weld joints are oriented longitudinally to the principal flow of stress for greater durability and more strength. Frame utilizes 345 MPa 50,000 psi yield high strength low alloy...
