SAMSUNG SE50-3 CRAWLER EXCAVATOR

Technical Description

The Samsung SE50-3 is a compact mini excavator engineered for precision earthmoving in confined spaces and light-duty applications. Powered by a Yanmar 4TNE94 diesel engine, this wheeled excavator delivers 51 horsepower at 2200 rpm with a maximum torque output of 133.8 lb-ft at 1600 rpm, providing reliable performance for sustained digging operations. The machine features a 0.3 cubic yard bucket capacity and achieves an impressive maximum digging depth of 12.6 feet with a maximum cutting height of 19 feet, making it suitable for trenching, site preparation, and general excavation work. The SE50-3 weighs 24,537.5 pounds and maintains a compact footprint with a width of 6.2 feet to the outside of tracks and a tail swing radius of 5.5 feet, facilitating maneuverability in restricted work areas. Its hydraulic system operates at 2990 psi with a pump flow capacity of 37 gallons per minute, supported by a 23.8-gallon fluid capacity reservoir. The undercarriage incorporates advanced track design with 10 track rollers per side, 2 carrier rollers per side, and 78 shoes per side, generating a low ground pressure of 4.4 psi to minimize surface disturbance. Standard operating specifications include a 23.8-gallon fuel capacity for extended operational periods, a 12-volt electrical system with 40-amp alternator supply, and maximum travel speed of 2.6 miles per hour. The swing mechanism rotates at 10 rpm, enabling efficient material handling. With its combination of powerful hydraulics, compact dimensions, and proven reliability, the SE50-3 remains an industry-standard choice for contractors requiring versatile, efficient mini excavation capabilities.
