HITACHI EX135USR CRAWLER EXCAVATOR

Technical Description

The Hitachi EX135USR is a mid-sized crawler excavator engineered for versatile construction and forestry applications. Powered by an Isuzu A-4BG1T diesel engine producing 80.5 horsepower at 2,100 rpm, this machine delivers robust digging performance with exceptional maneuverability in confined spaces. Operating at 29,101 pounds, the EX135USR features a compact rear body design that reduces the turning radius to 1,690 mm, making it ideal for tight job sites where larger equipment cannot operate efficiently. The excavator accommodates a maximum bucket capacity of 0.8 cubic yards and achieves impressive working ranges: 28.1 feet maximum cutting height, 18.3 feet maximum digging depth, and 27.3 feet maximum reach along the ground. Its ground pressure of 6 psi minimizes surface impact, while the track-mounted undercarriage with 19.7-inch shoes provides superior stability and traction on uneven terrain. The swing mechanism operates at 12.7 rpm, enabling rapid repositioning. With an 11.8-foot track length and 5.6-foot tail swing radius, this machine excels in confined work environments including forest road construction and logging operations. The hydraulic system holds 18.3 gallons of fluid, supported by a 66.1-gallon fuel capacity for extended operational periods. The pressurized cab offers operator comfort with responsive controls and excellent visibility. The EX135USR represents an optimal balance between power and compactness, delivering 11% greater traction force than its predecessor while maintaining superior stability through reinforced frame construction.
