Tilting Cooling Package The cooling package tilts for easy cleaning. Normal cleaning ensures that the cooling systems protects the engine to full capacity.
Enhanced Vibratory System
Pod-style Eccentric Weights The B-Series utilizes the proven Cat pod-style vibratory system. The system design significantly reduces the risk of contamination common to conventional designs that employ metal weights. Providing unrivaled reliability and performance, the Cat pod-style vibratory system is virtually maintenance free, with the first scheduled maintenance period at 3 years or 3,000 hours.
More Amplitude The B-Series vibratory soil compactors deliver enhanced compaction performance as the result of an increase in amplitude. Maximum amplitude is now amongst the highest in the industry, and provides a greater ability to put compaction energy into the ground.
Auto-vibe There is a new automatic vibration function. When vibration is engaged, vibration will cease as the compactor slows beneath a predetermined speed. When propel resumes, vibration recommences at a predetermined speed. This feature contributes to uniform, high-quality work.
Padfoot Drum Padfoot drums are ideal for compacting cohesive and semi-cohesive materials and can be equipped with either Cat exclusive oval pads or conventional square pads. The oval faced design provides deeper lift penetration, contributing to better overall compaction in cohesive soils than other pad designs. The square faced design provides optimal performance on semi-cohesive soils. It has a higher surface area, which allows it to create a good surface seal; but the larger face area does not allow deep lift penetration.
Reliable Power Train
Dual-pump Propel System The exclusive Cat dual pump propel system provides steady hydraulic flow for unmatched gradeability and blade function and now has been enhanced with electronic control for even better performance. The dual pump propel system provides separate hydraulic flow to the rear wheels and the drum for exceptional tractive effort in thick lifts, soft underfoot conditions or steep slope applications and allows for superior control on a grade in forward and reverse.
Cat Diesel Engine with ACERT™ Technology The B-Series Vibratory Soil Compactors feature a Cat engine that offers enhanced efficiency, better serviceability, ample power, and less noise. Cat engines meet emission standards. This innovative engine yields cleaner combustion and delivers steady power in all operating conditions with optimal fuel efficiency.
Large Cooling Package B-Series Vibratory Soil Compactors are equipped with a large cooling package and a variable speed fan. The large system helps to keep operating temperatures within optimal ranges. The variable speed fan reduces power draw by only operating at the speed that is necessary to cool the system. The reduced power draw contributes to more efficient use of fuel.
Eco-mode The B-Series vibratory soil compactors are equipped with Eco-mode, a function which helps to economize the use of fuel. When the machine idles for a predetermined amount of time, Eco-mode is engaged and the engine rpm is lowered. When the propel is engaged, higher engine speeds resume. For certain applications, Eco-mode can be engaged to operate the engine at lower rpm than normal. The lower engine speed results in less fuel burn. Eco-mode can also be programmed to shut down the engine entirely after a user-defined amount of time.
Automatic Speed Control Automatic Speed Control is a feature that allows the operator to select a maximum working speed. Once selected, the speed can consistently be reached by engaging the propel lever to the full stroke. Consistent speed contributes to compaction quality by making it easier to maintain compaction uniformity.
Comfortable Operator's Environment
ROPS/FOPS Configuration The ROPS/FOPS configuration features hand rails that enclose the platform area. A multi-position steering wheel adjusts for comfort. An adjustable, pivoting vinyl seat with seat belt and integrated operator's display is comfortable and keeps controls and operating information within easy reach. A 12-volt adapter provides power for personal electronic devices. A floor mat reduces vibrations. A specially designed fixture allows the operator to securely store lunch boxes. Cup holders are provided on the steering column. Large mirrors provide excellent views to the rear of the machine. An additional mirror package for enhanced rear visibility is available as an option.
ROPS/FOPS Cab Configuration The ROPS/FOPS Cab is an enhanced design that provides greater comfort for the operator. The cab features a multi-position steering wheel that adjusts for operator comfort. An adjustable, pivoting cloth seat with seat belt and integrated operator's display keeps controls and operating information within easy reach. A 12-volt adapter provides power for personal electronic devices. A floor mat reduces vibration. Glass panels and large exterior mirrors provide excellent views to the rear of the machine. Operator comfort is enhanced with climate control, including a heater and air conditioning. Large windows on the door and right side of the cab open wide for maximum ventilation. The cab is pre-wired for the addition of a radio (not included). A cloth headliner provides a smart, finished appearance. An interior mirror package and a deluxe, high-back cloth seat are available as an option.
Operator's Seat A new standard operator's seat design rotates to the right 20 degrees and integrates the propel stick and control console with LCD user display on the right armrest. The design allows the controls and display to comfortably follow the operator as the seat is rotated. The seat has a retractable seat belt. ROPS/FOPS configured machines will have a vinyl, all-weather seat. ROPS/FOPS Cab configured machines will have a cloth seat. A deluxe, high-back, air-ride seat is available as an option on Cab-equipped machines.
Multi-function LCD Display The operator's seat has a standard control console with a multi-function LCD display unit integrated with the seat arm. The display functions as a gauge cluster as well as provides diagnostics and additional data to the operator. Machines that are equipped with Cat Compaction Control output compaction measurements to the display as well.
Cat Compaction Control Option
Machine Drive Power (MDP) Machine Drive Power (MDP) is an exclusive technology only available from Caterpillar. MDP indicates soil stiffness by measuring rolling resistance. It is available on all Cat B-Series soil compactors- both smooth drums and padfoots. It can also be used by smooth drum machines equipped with padfoot shell kits. It is effective on all soil types, and can function when the drum is static or vibrating. MDP measures closer to depth of the lifts of materials being compacted, around 30-60 cm (1-2 ft) deep. MDP is more flexible than CMV because it can be used on all soil types, and because it measures more shallow than CMV, which allows results to be correlated with portable measuring equipment such as lightweight falling deflectometers and nuclear gauges. Because it does not require the drum to vibrate, there is less risk of de-compaction when used for proofrolling.
GNSS Mapping Capability Cat Compaction Control can be augmented by adding an optional Global Navigation Satellite System (GNSS) mapping antenna and a dedicated display unit, which provides SBAS-level accuracy and allows the operator to visually monitor results, map them to locations and save the data for analysis or documentation purposes. An RTK GNSS mapping capability is also available that provides greater accuracy than SBAS
Easy to Service
Tilting Cooling Package The cooling package tilts for easy cleaning. Normal cleaning ensures that the cooling systems protects the engine to full capacity.
Long Service Intervals Long service intervals contribute to more productivity and lower owning and operating costs. The vibratory system scheduled oil change interval is 3 years/3,000 hours. The hydraulic oil service interval is 3,000 hours. Engine oil service is every 500 hours.
Maintenance-free Hitch The hitch features sealed-for-life bearings that never need greasing.
