Utilaj nou, second-hand sau de inchiriat, dumneavoastra alegeti!
Elevator Mechanism
The elevator mechanism conditions material as it works, lifting material off the cutting edge and carrying it to the top of the load for true self-loading capability. The 623G is ideal for windrowing, blending material as well as breaking up vegetation in stripping operations.
Scraper Bowl
Caterpillar Scraper bowls deliver large loads with better retention, excellent material flow, fast cycle times and high productivity. Relocating the implement valve to the draft tube improves access and serviceability.
Serviceability
The latest electronic monitoring systems, grouped service points, and rugged Caterpillar components simplify maintenance and minimize downtime. New two-piece access doors open easily and stay open for better access.
Structures
Superior structural design delivers state-of-the-art ride, capacity, and material control while assuring the durability and reliability customers expect from Caterpillar.
Customer Support
The best parts availability and the best service capability will help keep your equipment working.
Power Train – Transmission
Planetary powershift transmission delivers excellent load capability. Redesigned front and rear axles accommodate wider brake shoes and drums. The neutral coast inhibitor and programmable top gear reduce wear while increasing machine performance.
Electronic Controls
Electronic controls improve machine response and provide advanced diagnostic capabilities that result in better machine availability. The Product Link option allows remote monitoring of location, machine system status, and alert indicators.
Power Train – Engine
Electronically controlled Caterpillar® engines with ACERT technology, modular radiator with 9 fins per inch, and an Electronic Control Module maximizes power to the cutting edge and exceptional haul road speed.
Operator Station
Convenient control placement and a comfortable work environment are keys to high productivity. Features include Single Lever Implement Control, an air seat suspension and improved instrumentation.
