CATERPILLAR CS423E STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CS423E is a robust static smooth drum roller engineered for efficient compaction on flat and graded surfaces with an operating weight of 15,410 lbs and a width of 71 inches. It is powered by a Caterpillar 3054C four-cylinder, 4.4L diesel engine delivering 83.2 hp gross (79.2 hp net), compliant with Stage II emissions standards. The engine features direct injection, natural aspiration, and a displacement of 269 cubic inches, providing reliable power and efficiency. The CS423E employs an exclusive dual pump propel system supplying balanced hydraulic flow to both the rear axle and front drum drive motor, enhancing gradeability and control while minimizing drum and wheel spin-out on low-traction surfaces. Its smooth drum measures 48.3 inches in diameter with a static linear load of 288.8 pounds per inch, producing centrifugal forces of 30,124 lbs at high and 15,062 lbs at low settings. The vibration frequency ranges between 1400 and 1914 vibrations per minute, with a nominal amplitude of 0.1 inches, optimizing soil compaction performance. Operating speed reaches up to 7.2 mph, supported by a 42.3-gallon fuel tank, 15.9-gallon hydraulic system, and 4.8-gallon cooling fluid capacity. The operator cabin height is 9.8 feet with a ground clearance of 15.9 inches, mounted on 14.9x24 tires. Designed for durability and ease of maintenance, the CS423E includes a pod-style weight housing with bearing lubrication intervals of up to 3 years/3,000 hours. It offers excellent operator visibility, comfort, and control for a wide range of compaction applications requiring smooth drum rollers.
