The Case CX145D SR is a compact radius crawler excavator in Case Construction Equipment's D Series lineup. Designed for urban construction, utility work, roadbuilding, and confined job sites, it combines a short tail swing design with a mid-size operating class. The CX145D SR is typically equipped with a fuel-efficient diesel engine, hydraulic system optimized for digging and lifting, and a comfortable operator cab with modern controls. Common attachments include buckets, hydraulic thumbs, and breakers. Its reduced rear swing radius supports work near structures, traffic, and other obstacles while maintaining digging performance and versatility across general excavation applications.
