New 311F LRR Excavator from Caterpillar

Caterpillar has introduced its new Cat® 311F LRR excavator. Powered with a 52-kW (ISO 9249) Cat C3.4B engine that meets EU Stage IIIB emissions standards, the new excavator features a reduced radius that limits over-the-side tail swing to just 508 mm, making it ideal for space-restricted job sites.

A massive 2450-kg counterweight gives it the stability and working capacity of conventional excavators, and the unique design allows for use of a full-sized rollover protective structure (ROPS) cab.

The machine’s compact size is complemented with fuel-saving features and an efficient hydraulic system that powers through tough digging and easily handles a range of work tools.

Emissions control is transparent to the 311F LRR operator, requiring no intervention and causing no interruption of work cycles.

The 311F LRR can be equipped with the Caterpillar Tool Control, including 10 pre-programmed tools, precisely limiting flow and pressure at the touch of a button. The combination of auxiliary hydraulic systems and couplers allows the use and quick change of a variety of work tools, for greater machine versatility and productivity.

Major structures for the 311F LRR are designed for durability. The upper frame incorporates special mountings to accommodate the heavy-duty ROPS cab, and the standard long undercarriage uses high-tensile-strength steel components for long service life in a wide range of applications.

The reach boom and stick use internal baffle plates for added strength and are ultrasonically inspected to ensure weld quality. In addition, box-section multi-plate fabrications use high strength castings and forgings in high stress areas such as the boom foot, boom nose, cylinder mounts, and stick foot.
