CB4.4

Overview

The CB4.4 is a 3-5 metric ton versatile machine that can be used as the only vibratory roller on small sized jobs or on larger jobs as a support roller for high-production rollers. Its high amplitude and drum width give it the capacity to achieve a tons-per-day production rate that make it an excellent match for shoulders, small parking lots, lane additions, or other similar sized jobs.

Features

Simple Operation

• The bright LCD display and LED console lights optimize control for day and night operation. Roading and working lights include front lights with turn signals, a single rear working light with turn signals and a warning beacon.
• Powerful lift cylinders enables a single person to raise and lower without the use of tools. A fixed ROPS is also available. The foldable canopy is compatible with fixed or foldable ROPS.
• Multiple language options are available for crew diversity. The display screen options include; engine speed, fuel level, hour meter, coolant temperature, hydraulic oil temperature, voltage. The default screen includes: engine speed, fuel level, hydraulic oil temperature and visual indicators to keep the operator informed of low water level (spray system), Eco-mode, drum selections, lights, water spray settings, traction control, regeneration, parking brake, and warning indicators.
• Intuitive, multi-function control panel with vandal protection enables good performance. Easy viewing LCD Display and Vibrant LED lights on the control panel simplify operation in both day and night operation. Integrated vandal cover protects value.

Optimized Power

• Two engine offerings are available to meet local emissions requirements. An electronic control module (ECM) helps enable steady operation. The engine includes an electric fuel-transfer pump and fuel tank sized for 12-14 hours of runtime. Multiple engine speed settings enable operators to customize to the specific application and environment. Eco-mode can reduce fuel consumption up to 8 percent, depending on model.
• The cooling system provides ambient capability of 49�C (120�F) @ 80 percent load. The hydraulically driven fan motor enables variable speeds and reduces sound levels.
• A traction control option is available in a pin-on design that offers quick installation. Field retrofitting can be completed in an hour.

Efficient Compaction Performance

• Two frequency selections deliver excellent compaction performance and low sound levels. Selections of 55 Hz (3,300 vpm), and 48 Hz (2,880) are available.
• The vibratory system is equipped with automatic vibration de-activation when the propel lever is in the neutral position. Vibration is available on front, rear, or both drums. The exclusive eccentric weight shaft delivers quick starting and stopping times and a bearing service interval of 3 years or 3000 hours.
• A 50 mm (2 in) drum offset capability enhances control near curbs and offers more coverage.

Best-In-Class Water Spray System

• Spring loaded scrapers keep the drums clean and distribute water evenly for reduced consumption. Robust, retractable hinges help maintain contact with the drum and retract when roading to reduce unnecessary wear. Scrapers are located at the front and rear of each drum.
• The protected spray bar is designed to fight winds, while a low water level indicator keeps the operator informed. A single water tank with a capacity of 308 L (81 gallons) provides more hours of operation between refills. The intermittent and continuous modes increase control and efficiency. Triple filtration in the tank, before the water pump, and in spray nozzles provides reliability. An antifreeze option provides protection in cold weather, while a single point to drain and filter water offers easy service.
