BOMAG ideas envision electrical, LPG BW 120 rollers; totally autonomous ROBOMAG compactor (VIDEO)

The ROBOMAG totally autonomous tandem vibratory curler

At ConExpo 2020, BOMAG gave a glimpse of the corporate’s imaginative and prescient for the way forward for asphalt compaction, with idea rollers that run on battery, liquified petroleum gasoline or with no operator on the machine.

The corporate displayed its idea alternative-drive BW 120 AD-5 tandem rollers, one with an  electrical engine and one other that runs on LPG, for working in areas with strict environmental necessities. The sales space was additionally occupied by the ROBOMAG totally autonomous tandem vibratory curler, which the corporate unveiled finally yr’s Bauma present in Germany.

BOMAG rolled out its idea electrical and LPG drive techniques on its BW 120 AD-5 tandem compactor.

The normal diesel mannequin runs on a 33-horsepower Kubota engine and has a 47-inch compaction width. The choice fashions are geared towards indoor, tunnel, inner-city or different tasks the place low emissions are wanted.

Tim Eisfeld, BOMAG director or advertising and marketing and product administration, says the electrical model has been requested extra in Europe, whereas the LPG model is predicted to draw extra curiosity in North America.

The tank on the BOMAG BW 120 AD-5 LPG may be modified in 5 minutes, and an operator can get 5 hours of compaction on one tank, the corporate says. In comparison with the diesel model, the gasoline mannequin considerably reduces emissions –  95 % much less nitrogen-oxide and 15 % much less carbon-dioxide and advantageous mud, in keeping with BOMAG.

Together with better emissions discount, the gasoline model delivers 7 extra horsepower than the diesel mannequin, and BOMAG notes that LPG sometimes prices about 40 % lower than diesel.

The electrical BW 120 AD-5 E reduces emissions even additional, all the way down to zero. Additionally it is a lot quieter than diesel rollers.

The electrical-drive engine delivers 24.eight horsepower, or 18.5 kilowatts. At this level, battery life is simply 2.5 to 3 hours, which the corporate is working to enhance, Eisfeld says. He provides, although, that in lots of rental functions for restore work, a curler is used for just one.5 hours.

The electrical curler’s price could be double that of the diesel mannequin, so it’s not for everybody. However the firm notes that upkeep is far less complicated and results in financial savings of about 40 %.

The corporate used ConExpo to realize enter from sales space guests on any modifications to be made to the idea fashions earlier than they hit the market.


Autonomous future


The electrical and LPG compactors are anticipated to hit the market a lot ahead of the ROBOMAG, though BOMAG’s press launch hints that it represents the corporate’s imaginative and prescient for the “not-so-distant future.”

Eisfeld says the idea tandem vibratory curler is presently totally operational however nonetheless years away from launch.

“As a producer, we might be prepared quicker than the market is prepared for taking it,” he says.

Regardless of the longer time-frame, BOMAG continues to enhance the autonomous curler.

At ConExpo, the futuristic machine was geared up with Asphalt Supervisor, BOMAG’s new automated clever compaction management, monitoring and documentation system. The system, additionally accessible on among the firm’s latest rollers, mechanically adjusts drum vibration for constant mat high quality, stopping bow waves and scuffing, the corporate says.

ROBOMAG may be operated totally autonomously in an outlined work space. It makes use of GPS, LIDAR lasers and positioning sensors to information its path. It detects objects to keep away from collisions. It will also be operated autonomously by manually coming into motion patterns, and it may be operated manually by distant management.
