The bauma 2007 28th International Trade Fair for Construction Machinery, Building Materials Machinery, Mining Machines, Construction Vehicles and Construction Equipment proved to be the most successful edition in the exhibition's history.

Held this past April in Munich, Germany, the show outstripped the 2004 event in terms of exhibition space and exhibitor and visitor numbers. It hosted a record 500,000 attendees, representing a roughly 20% increase. The proportion of international visitors reached 160,000, or approximately 30% of the total.

The event also featured 3,041 exhibitors covering 180,000 sq. meters of hall space and 360,000 sq. meters of outdoor exhibition space.

Following is just a small sampling of products presented at bauma 2007. For more information on any of these products, just turn to the reader service card following page 12.

Dynapac LG300 Plate Compactor
The LG300 forward and reversible plate compactor is suited for soil applications, road repair, maintenance work and general compaction tasks. Speed and compaction depth are regulated via hydraulic servo control technology of the electric element. This ensures plate motion maintains a consistent level of smoothness. The design includes a strong, shock-resistant steel cover to protect vital components.

The unit comes with a 7.9-hp Honda gas or 5.6-hp Hatz diesel engine. It delivers 4,200-vpm frequency, an amplitude of .07 in. and up to 9,000 lbs. of centrifugal force. It can work at speeds up to 82 fpm.

Trimble Construction Manager
The Trimble Construction Manager version 1.9 is a fully integrated solution for managing construction equipment and operations. This version introduces charts and a dashboard view designed for users to visualize critical operational information for their construction fleet.

The program's new functionality is designed to enable simple identification of under-utilized equipment or bottlenecks in construction operations. Some examples include bar charts displaying equipment utilization, work time compared to idle time and a timeline of equipment activity through the day.

The new version also includes a detailed utilization report and maintenance alerts.

Komatsu PC138USLC-8 Excavator
The PC138USLC-8 short tailswing excavator has an operating weight of 31,107 to 32,568 lbs., and is powered by a 92-net-hp Komatsu SAA4D95LE-5 common rail injection, Tier III-ready engine. The unit provides increased lift capacity compared to the PC120LC-6 conventional-type excavator, while reducing the tailswing radius by 27%.

Improvements to the hydraulic system enhance productivity and efficiency. A single pump, double-flow system and pump flow merge divide valve improve swing acceleration and steering performance.

The operator station features an easy-to-view, 7-in. multi-function monitor incorporating five work modes. In addition, fingertip command of two different breaker and attachment flow selections provides a total of four flow settings.

The EMMS (Equipment Management Monitoring System) and Komtrax fleet monitoring system are standard equipment.

Vermeer HG200 Horizontal Grinder
The 5,500-lb. HG200 compact horizontal grinder processes brush and sizes the end product in one pass. It shares the same platform as the BC1000XL brush chipper, and is powered by an 85-hp Cummins turbocharged diesel engine.

The hammermill drum is able to process light contaminants such as nails, small gravel/stone aggregates, bolts, glass fragments and plastics. The SmartFeed feed-sensing control system automatically stops or reverses the feed rollers and infeed conveyor according to engine rpm drop. The clutchless PTO system combines the throttle and clutch engagement mechanisms to prevent the drum from being engaged at a high rpm.

An optional 2-ft. extension is available for the 17-in.-wide, 4-ft.-long infeed conveyor belt.
