The CB2.7 GC is one of Caterpillar’s most popular paving machines in Australia, with popularity expected to grow. Chris Harkness and Dean Alley from Caterpillar give insight into the versatile roller and the features that help set this machine apart.
The Cat CB2.7 GC, originally known as the CB2.7, is another iteration in the tandem combination utility compactor range, with classification changes to deliver increased productivity and efficiency, along with simpler operation and easier maintenance.
Industry Territory Manager Chris Harkness says the development of the CB2.7 GC roller came from the need for a product update.
“The 2.7 tonne utility compactor has proven itself a very popular model in Australia and is Caterpillar’s biggest selling utility compactor,” he says.
“Its size is perfect for small and medium asphalt jobs that include parking lots, and urban streets. It works equally as well in landscaping or house job site compaction.”
The new CB2.7 GC has efficiency specifics including a range of updates to improve operator experience.
“It’s important to be able to see the outside of the drums when in operation. We have tapered this so operators have a clear line of site when working,” Harkness says.
“This improves efficiency greatly. You don’t have to lean too far or even leave the machine to see where the drum aligns. The narrow drum means a clear line of sight directly from where you’re sitting.”
Efficiency also comes from the new compaction measurement value (CMV) displayed to the operator for improved compaction performance and consistency.
Territory Manager Dean Alley says features like this allows operators with a range of skill levels to use the roller with ease.
“The CMV feature is great especially for asphalt compaction,” he says.
“It is designed to let the operator know when the machine has reached the desired compaction level – and it does this job extremely well.”
Development of the CB2.7 GC also considered safety a high priority.
Some of the key safety specifics include a new 76 millimetre high-visibility orange seatbelt, optional LED lighting for night works and a seat with an operator pre-sense sensor to prevent unintended operation while out of the machine.

Simpler to Operate
Another key aspect of the CB2.7 GC is the updated water spray system.
Alley says the updated system is an essential part of the machine, made to be noticeable and easily accessible.
“We’ve worked hard to optimise the whole water spray bar system,” he says.
“The gauge is in a place where you can easily understand water levels, an aspect that was essential through the development stage. We also made sure to keep Cat’s triple filtration system so the water remains clear of any possible debris, making it easy for operators to see.”
The water spray system also comes with an optional test mode, another key feature acknowledging safety as a priority. Harkness says that, especially with asphalt compacting, being able to test where the water is spraying is critical.
“The CB2.7 GC spray test mode means you don’t need to leave the machine idling and creating noise to test the water spray,” he says.
“You can simply turn a dial located on the machine to switch to test mode, get out of the roller and check that the nozzles are spraying correctly and that there are no blockages in the way to optimise coverage.”
Harkness says Caterpillar wanted to ensure this system worked well for operators, knowing the importance of water.
“In the business of asphalt, if you run out of water, you might as well run out of fuel. If water runs out, the system will begin picking up asphalt and causing damage to the machine. The test-mode is designed to avoid these risks,” he says.
“Having a water level gauge just a quick glance away is designed to assist in quick and efficient monitoring – perfect for this easy-to-use machine.”
The development and upgrades of the new CB2.7 GC originated from one simple thing, operator feedback. Harkness says that feedback from the very people the machines are designed for, is the reason why each iteration of the roller keeps getting better.
“Operator feedback is very important in the development of any machine Caterpillar provides,” he says.
“People using the equipment were reporting that there wasn’t enough coverage, so we made sure to add an extra nozzle for water spray and an internal application across the drum.”
Other productivity specifics of the CB2.7 GC include new 14 millimetre thick drum shells for longer durability and two vibe frequencies for simple and versatile operation.
Ensured peace of mind
Upgrading the CB2.7 to the CB2.7 GC also meant the upgrade of the engine.
Alley says the C1.7T engine with 18.4 kilowatts is Tier 4 ready.
“The new compactor line-up features an electronic technician (ET) that is built into the C1.7T engine with diagnostic software which enables quicker access to diagnostics,” he says.
“Through ET, you have the ability to capture critical information around the operating data as well as track the machine’s location.
“It gives you a sense of safety and reassurance for your equipment; very useful in case of stolen or missing property.”
According to Caterpillar, the updated engine also has a 55-litre fuel tank for longer run times and comes with an auto idle shutdown feature for fuel economy.
Quality and reliability
Harkness says Cat dealers’ after market offers is what really sets them apart.
“The CB2.7 GC roller is Cat’s biggest selling roller, but despite the flexibility, ease-of-use and efficiency, our after-market offers, and extended warranties offered by our network of dealers is what makes us unique,” he says.
Alley continues the emphasis on Caterpillar’s service.
“We always jump at the opportunity to offer aftermarket service to our customers through our dealers,” he says.
“This all plays a huge part in what Cat is about.”
The updated CB2.7 GC roller is now available in the Australian market.
