Cat is expanding its product range to include asphalt pavers in the 8-foot size class

To contractors who ask about a Caterpillar compact paver, your wish has been granted.

Cat has filled the gap in its product offering with a new line of 8 foot paver and screed combinations. The asphalt pavers AP400, AP455, AP500 and AP555 as well as the asphalt planks SE47 V and SE47 FM are designed for small, narrow work such as narrow streets, driveways and small parking lots.

“Compact pavers and screeds offer opportunities for both large and small contractors,” says Cat sales consultant Jon Anderson. “For large contractors doing extensions and shoulders, this is the perfect machine to do that at a lower cost. Smaller customers have the opportunity to step up and do larger jobs that they have always wanted to bid for but didn’t feel they had the equipment for. ”

The SE47 V screed can be extended to any width between 8 and 15 feet 6 inches, with a maximum width of 20 feet. The screed SE47 FM offers a standard paving area between 2.40 m and 4.5 m with a maximum width of 20 m 6 inches. Both planks offer installation depths of up to 10 inches.

“One of the hardest things to do is do a job where the paver is too big and you have to do it all in the narrowest possible width,” says Anderson. “It’s a real challenge, it opens up new opportunities.”

Easy to load or road

When switching between multiple jobs a day, equipment needs to be easy to transport. Cat says these 13-15 ton machines don’t require special permits to move and have convenient attachment points.

Less than 18 feet 6 inches long and 8 feet 6 inches wide, the pavers easily fit on trailers and can be moved with other equipment. In addition, the front loading angle of 17 degrees and the high freedom from bumpers simplify loading without additional locking material.

Driving instead of charging? Anderson says the versatile chassis design provides “excellent traction and speed for the journey to the next take-off point”.

The Cat Mobil-trac undercarriage design used on the AP455 and AP555 has a unique four-bogie system with self-tensioning batteries and center guide blocks. This helps prevent slippage and reduce wear, while the oscillating carriages ensure smooth transitions when exiting the cut across transverse joints from milling and filling applications.

A simple wheel chassis design is also available with sand rib or radial drive tires. The AP400 can be equipped with a front wheel assist option, while the AP500 can be equipped with a front wheel assist or all-wheel drive option for more power on soft surfaces or when pushing heavy loads.

Simple, intuitive operation

Simplified menu structures offer touchscreen activation from the main screen.Equipment worldStandardized controls across the Cat road construction line make it easy for crew members to move between machines and train new employees.

“We have some new, simplified menu structures that make changes easier, and single-touch activation for the feeder system,” says Anderson. “The new display offers fantastic visibility even in bright sunlight.”

The screed heating, smoke evacuation, vibration settings and washdown system are all accessible at the push of a button from the main menu, which helps the operator start faster and increase productivity.

Versatile new screeds

Screeds with rear or front mounted extensions allow contractors to meet their application needs. The SE47 V is a rear screed, ie the hydraulic extensions are located behind the main screed. This design allows the material to naturally flow to the end gates for smooth, stable performance.

The Schlouch crew tested the AP455 with the SE47 V in the field last year. Here are some of the reasons why they prefer the rear-mounted screed:

  • Full catwalk: “It has a full catwalk. When you extend the extensions, it extends the walkway so you can continue to run until the extension ends, ”says Powell. This allows for excellent visibility when paving neighborhoods around rainwater inlets.
  • Durability, rigidity and weight: the setup is also well suited for high-tolerance applications such as sports fields. “The extra weight of the screed behind the machine gives us a nicer mat from behind, slightly better compaction directly behind the screed, and enables us to achieve good results,” says Powell.

A front-mounted system can be a better option for contractors who frequently have to maneuver around obstacles like curbs and light poles. The SE47 FM is equipped with hydraulic extensions in front of the main screed and offers a smaller footprint, which reduces the manual work at the beginning of the paving. When the installation width is reduced, material is quickly withdrawn into the screw chamber.

For construction companies that require a wider installation capacity, optional expansion packages and Bermen attachments are available for the SE 47 FM.

Fuel saving performance

Cat has equipped the new pavers with an eco mode which, in combination with automatic cruise control, reduces fuel consumption. In most conditions, the engine can run at a slower speed and still provide the power required to meet the power requirements. If necessary, the engine automatically adjusts to a higher engine speed if certain load conditions are met.

The AP400 and AP455 have a 120 hp Cat C3.6 engine, and the AP500 and AP555 run on a 148 hp Cat C4.4 engine. Both engines meet the Tier 4 Final emissions standard.

Improved visibility

Operators will immediately appreciate the improved visibility into the container and the unrestricted forward view of these compact machines. The exhaust chimney has been integrated into the new hood design and does not protrude upwards like on other Cat paver models. The small footprint of the paver offers excellent mobility in confined spaces and for applications with little ground clearance.

“Some of the things that caught our eye was the visibility around this machine,” says Powell. “Above all, the elimination of a stack in front of the engine compartment. As a result, the operator can now really see what is in front of him, as well as a slightly smaller hopper size on the machine. When you tip trucks into the paver, the spotter standing next to the machine can see into the hopper, see when it is full, see when the truck is empty and have a better view of this area. “

Smooth material flow

Smaller augers ensure a smooth flow of material in small widths and help contractors to achieve quality goals. The 14-inch diameter screws move material efficiently through the screw chamber. When using separating shoes or when installing in narrow widths, the operator can control every material feed sensor. Simply switch to manual and use the proportional rotary control for the feed system.
