New 8530 asphalt paver from LeeBoy

LeeBoy’s new paver offers easier maintenance

LeeBoy has taken the wraps off its all-new 8530 paver, as well as the upgraded 8516D and 8520B models. Power for the 8530 comes from a Tier 4 Final compliant Kubota diesel rated at 93kW, running at 1,900rpm for working use. The machine is fitted with the HD Pro screed featuring electric heating, and which offers paving widths of 2.44-4.72m (8’-15’6”).

A key feature of the machine is the way its access for maintenance has been improved over earlier models from the firm. Previously, the flight chain adjustment, hydraulic tanks and generator, for example, were located under the hopper on previous generation LeeBoy pavers.

This meant maintenance to any of these items required unbolting the hopper and lifting it off to provide access. These items have now been moved to the deck, with the fuel tank, an item rarely requiring maintenance, now located under the hopper instead. The fuel tank offers a 133litre capacity, which a spokesperson for the firm said, “…gives you more than a day’s shift.”

Service access to the engine and hydraulics is said to be good, with daily maintenance points under a cover that can be raised electrically. The deck design gives the operator good forward visibility over the hopper while the seats can be swung out over the side for a view of the screed edges. Two operator seats are typically fitted as standard, with full control consoles.

The 8530 is now available, having benefited from an intensive testing programme in different climates, to ensure it offers continuous working. In addition to being tested close to the firm’s plant in North Carolina, intensive trials were carried out in the hot, dry air of Las Vegas, as well as in the more humid conditions in Florida.

LeeBoy has also upgraded its 8616D and 8520B paver models. These share the improved maintenance access of the new 8530, with the fuel tanks now relocated under the hoppers, while the hydraulics and generators are on the deck with the engine. Both machines also benefit from Tier 4 Final compliant Kubota diesels, rated at 79kW for the smaller 8616D and 93kW for the 8520B.

As with the 8530, the 8520B is equipped with the HD Pro screed, offering paving widths of 2.44-4.72m (8’-15’6”). Another important feature of the 8520B is its hydraulically extendable push roller system, which allows the machine to work with different sizes of tipper trucks. Meanwhile, all three machines can be equipped with 2D grade control technology from Topcon Positioning.

At present these three machines are available with Tier 4 Final compliant engines only. However, the smaller machines in the LeeBoy range, from the 8510 down, are also offered with Tier 3 compliant engines for use in Latin America.
