A multi-task workhorse suited for anything, from trenching to tunnel wall scaling

The Cat 305.5E2 CR can be fitted with an optional rear view camera. In addition to maximum workplace safety, this improves operator productivity and efficiency through a 360 degree view of the job, making tasks easier to execute.

Manufactured at Caterpillar’s Athens factory in Georgia, USA, the latest generation Cat Cat 305.5E2 CR (Compact Radius) mini excavator has now been launched into the southern African market for diverse, high performance applications across the building, construction and allied industrial segments, including the refractory and mining sectors. 

A multi-task workhorse suited for anything from trenching to tunnel wall scaling (when fitted with a hammer), the Cat 305.5E2 CR has an operating weight of approximately 5 335 kg (with cab and standard stick) and a transport length (with boom) of 5 330 mm, making it well-suited for towing or truck loaded transport, and rapid deployment. The shoe width is 400 mm, with rubber tracked undercarriage fitted as standard.

The Cat 305.5E2 CR has a dig height and depth of 5 330 mm and 3 470 mm.

Like all E2 Series models, the Cat 305.5E2 CR comes equipped with a new, innovative cab design and a high definition hydraulics system. The pin back door on the cab offers a wider entry into an operator environment with industry leading comfort, ergonomically designed 100% pilot controls, adjustable arm rests, updated air and heat controls, and excellent visibility for superior productivity and safety on the job site.

Other key features include 200 degree bucket rotation; dozer blade floats; the Cat 305.5E2 CR’s compact radius design (the upper body stays within the width of the undercarriage during rotation); and two way hydraulic lines, which makes the machine work tool ready. The Cat 305.5E2 is compatible with all 5 tonne Cat E Series work tools, including couplers, thumbs, buckets, hammers, augers, shears and rippers. An optional hydraulic quick coupler further extends their versatility, enabling rapid tool changeovers for diverse on-site tasks.

The Cat 305.5E2 CR features industry leading comfort, ergonomically designed 100% pilot controls, adjustable arm rests, updated air and heat controls, plus excellent visibility for superior productivity and safety on the job site.

“200 degree bucket rotation allows deeper flat back trenches without having to reposition the machine; plus more material retention is achieved at the top of the lift cycle while truck loading,” explains Barloworld Equipment product marketing manager, Desigen Naicker. (Barloworld Equipment is the Cat dealer for southern Africa.)

Power is provided by a Cat 2.4 model engine generating a rated net power output of 32,9 kW (ISO 9249). Excelling in mass excavation roles, the maximum bucket breakout force is 50,9 kN, with a maximum dig depth and height of 3 470 mm and 5 330 mm.

On the ground, precision is delivered by the machine’s high definition hydraulic system. This load sensing, flow sharing set-up provides improved efficiency, controllability, and reduced operating costs. Additional savings are achieved by the Cat 305.5E2 CR’s new Power on Demand feature, which replaces the previous generation Eco mode. Power on Demand ensures optimal fuel burn by automatically selecting the appropriate engine rating selection to match each work task.
