المميزات الرئيسية:

Proven Power Unit The excavator is equipped with the Cat C1.8 three-cylinder turbo diesel engine, delivering 23.6 kW (31.6 HP) net power at 2400 rpm. This reliable factory engine provides strong low-speed torque, stable output under continuous light loads and good fuel economy for long-hour site operations. It adopts optimized fuel injection technology and comes with auto idle function to reduce fuel consumption during standby.

Stable Heavy-Duty Build With an operating weight of approximately 3,520 kg, the 303.5E2 CR adopts CR compact radius tracked design. Minimal tail swing avoids hitting walls and obstacles in narrow construction areas. Retractable rubber tracks can protect pavement and ground surface. Reinforced boom, stick and X-frame structure resist digging impact and extend service life. Tilt-up cab design makes daily maintenance much easier.

Versatile Digging & Loading Performance Bucket capacity ranges from 0.08 to 0.12 m³ and maximum digging depth reaches 3,180 mm. The machine efficiently completes foundation excavation, mass earthmoving, backfilling and site material shifting. Auxiliary hydraulic lines support quick installation of hydraulic breakers, augers for multi-purpose construction tasks.

نظام هيدروليكي فعال Caterpillar’s advanced load-sensing hydraulic system delivers smooth and precise joystick control. Pressure compensation technology enables coordinated multi-function movements and fast cycle times, improving productivity during repeated digging, slewing and dumping operations. Adjustable auxiliary hydraulic flow fits different attachments.

Serviceable & Operator-Centric Design Ground-level service access points simplify daily inspection and routine maintenance to minimize downtime. The spacious operator cab provides good all-around visibility and ergonomic controls, lowering operator fatigue during long working shifts in various construction environments.
