Redesigned cabs include an operating control layout based on the larger 6th generation wheel loaders.

Roadtec SB-2500D Shuttle Buggy
The SB-2500D Shuttle Buggy material transfer vehicle (MTV) can store and transfer hot-mix asphalt material from a truck to a paver for continuous paving. Its anti-segregation auger remixes materials just before they are delivered to the paver. A 25-ton surge capacity allows trucks to unload material immediately and return to the asphalt plant.

The unit is powered by a 300-hp Caterpillar C9 six-cylinder, Tier III diesel engine. All-hydrostatic ground drive allows for continuously variable speed control with two speed ranges. The unit has a truck unloading capacity of 900 tph and can load a paver at up to 550 tph.

Features include dual operator positions with a pivoting control panel for use from either station; 55° conveyor swing to either side of center; and an optional windrow pickup head.

HAMM HCQ Asphalt Navigator
The HCQ Asphalt Navigator is a new analysis and documentation system for the compaction of asphalt layers. Its network function enables continuous exchange of data between several rollers compacting the same layer. This enables roller drivers and site managers to see and assess the current state of compaction at any time across the entire site.

The system determines the number of passes, asphalt temperature and machine-related factors, such as model, speed and compaction method (including frequency and amplitude), and takes into account asphalt parameters such as asphalt type and rigidity. These values are linked to the position data from a DGPS receiver on the roller to produce color-scaled temperature, pass and compaction maps.

The system can be integrated into all road rollers at the factory or retrofit to existing models.

Genie GS-3232 Scissor Lift
The self-propelled GS-3232 lifts up to 500 lbs. and has a 38-ft. maximum working height. With its compact footprint of 7 ft. 11 in. long and 2 ft. 8 in. wide, it can easily fit through standard doorways. Dual front-wheel drive and a zero inside turn radius ensure maneuverability in restrictive work environments. A 3-ft. extension deck also allows workers and tools to utilize the maximum amount of platform work space.

The lift comes with an automatic leveling hydraulic outrigger system that is able to level on slopes of up to 5° side-to-side and 3° front-to-back. Also standard is a four-wheel braking system and advanced electronic control system.

Topcon SiteLINK
The SiteLINK wireless communications mapping, data logging, reporting and asset management system for off-road equipment provides the ability to work with any make, model or type of equipment on site, regardless of manufacturer and age. The technology is based on utilization of Mesh Radio Networks built on a standard Wi-Fi environment. The system can also pinpoint via GPS any make of equipment on a jobsite, serving as a built-in theft protection program by adding easy to configure geo-fencing functions.

In addition to monitoring fuel levels, oil pressure, temperature and hours of use, data that can be collected, stored and processed for individual machines include productivity, geometry files, real-time machine position and history with optional GNSS+ receiver hardware and percent of selected jobs completed. The data can be accessed anywhere you have Internet hookup or cell phone connection.
