Over · Caterpillar 311Overzicht
The Caterpillar 311 is a crawler excavator in the 12-tonne operating class, producing 79 hp and equipped with a 0.55 m3 bucket capacity. At an operating weight of 12,516 kg, it occupies the upper boundary of the compact-to-mid excavator segment, offering a balance between jobsite maneuverability and productive digging force. It is a widely recognized machine in general civil and construction markets, supported by Caterpillar's established parts and service network.
Typische toepassingenWaar deze machine wordt gebruikt
Machines in this weight and power class are typically deployed on foundation excavation, utility trenching, road construction preparation, and site clearance work. The 0.55 m3 bucket capacity suits medium-volume earthmoving tasks where cycle efficiency and fuel economy are prioritized alongside raw output. Secondary applications include drainage work, pipeline installation, and light demolition support on constrained urban or suburban sites.
Tweedehandsmarkt inspectieWat je moet controleren voordat je koopt
Inspection of a used excavator in this class should prioritize undercarriage wear, as track components, rollers, and sprockets represent a significant portion of ownership cost on crawler machines. Assess the boom, arm, and bucket pins and bushings for play, and check hydraulic cylinders for seal condition and rod scoring. Engine bay inspection should confirm coolant and oil condition, absence of blow-by, and clean air filtration. Request all available service records to verify maintenance intervals have been followed. Confirm that all auxiliary hydraulic circuits function correctly, particularly if attachments are included in the transaction. Structural inspection of the mainframe and slew ring for cracks or abnormal movement is standard practice for any crawler excavator of this age and class.
Huidige marktPrijspositie
Within the 12-tonne crawler excavator class, the Caterpillar 311 is most commonly cross-shopped against the Hitachi EX120 and Hitachi ZX135US. The ZX135US operates at a slightly higher weight class and is positioned as a more powerful alternative, while the EX120 represents an older-generation comparable. The Caterpillar 311 distinguishes itself through brand familiarity and parts network density rather than outright specification differences at this weight. Within any given market, price positioning is driven by accumulated machine hours, undercarriage condition, attachment configuration, regional service availability, and overall mechanical and structural condition. Machines with low hours, verified service histories, and complete attachment packages, such as hydraulic thumb or quick coupler fitment, will consistently occupy the stronger end of the value band relative to high-hour or poorly documented examples.
