Plus Series pavers

The Pavers AF 5000 Plus (on crawler tracks) and AF 5500 Plus (on tires), produced by Ciber Equipamentos Rodoviários in Porto Alegre, a city located in the south of Brazil, bring technological innovations that increase productivity and safety. One of the innumerous advantages of the Plus Series is the intelligent automation system.

The machines are used for paving city roads, airports, as well as municipal, state, and federal highways. They have the capacity to spread up to 450 t/h for pavements, 2 to 30 centimeters thick, at 1.9 to 5.3 meters wide.

This equipment comes with the general standard of components which unifies the new identify of Ciber pavers. The changes in the chassis design had the purpose of meeting the requirements of the various pavement applications such as the stabilizing bases used in bases and sub-bases. The new design makes it possible to alleviate tensions, distributing the efforts more uniformly along the chassis.

The control system is totally innovative and modern with an ergonomic panel, as well as a display for monitoring the functions and management by controlling modules through the Canbus-type system. The Plus Series pavers also come with a protective canopy that keeps the sun rays off the operator. This canopy is made of resistant material with side flaps to fully protect the operation area.

Another characteristic that comes with the model is the material transportation system (augers and conveyors). "This resource offers variable control speed, augers 380 millimeters in diameter, high load capacity sleeve bearings and bearings with external lubrication. Some of the advantages of this resource are the excellent flow control of mixture, more technology and efficiency, as well as the possibility to meet a greater number of paving applications," explains Rodrigo Pereira from Ciber's Marketing Engineering.

Adding value

The optional systems are used depending on the requirements of each job site. The ultrasonic leveling and automatic lubrication are some of the options made available for adding value to the machine. The new lubrication methodology, for example, brings important benefits such as basic control over the lubrication process, elimination of contamination risks, lowering costs with production, maintenance, and labor, reduction of wear, and increase of the useful life of the components, shortening the time for stopping for lubrication, which increases productivity.

The Plus series counts on an intelligent automation system with three microprocessing controllers designed specifically to operate with Off Road type of equipment. These components monitor and control all the functions by means of a display that not only informs real-time the equipment's parameters through its user-friendly interface, but also indicates to the operator what to do if certain components fail or in emergency situations. The automation components are connected by means of a high-speed network, which makes the operation much more precise and reliable.

In operation

Ciber's pavers are in operation at the construction site for Natal's new international airport, a city located in the state of Rio Grande do Norte in the northeast part of Brazil. Up until now the base and sub-base have been laid with 45,000 m³, which is 45% of the total forecasted for this stage. "More or less 10,000 metric tons of asphalt mixture has already been laid," informs Rodrigo Pereira.

The airport is being built in São Gonçalo do Amarante, a city close to Natal, an will have the capacity to handle up to 40 million passengers a year beginning in 2020. The inauguration is scheduled for 2009. This first stage will include the access terminal, a cargo terminal, patio, and take-off and landing strip 3,000 meters long and 45 meters wide. The idea is to make it a full-fledged airport complex and has an area planned for hotels and theme parks.
