Aquajet Systems AB has introduced the Ergo Climber attachment for its new Ergo System hydrodemolition robot. The Climber attaches to any standard scaffolding pipes and robotically moves along them to deliver powerful hydrodemolition forces for systematic vertical concrete or refractory removal, such as high-rise construction, petrochemical facilities, and other industrial applications.

"Combining the power of the Ergo System with the maneuverability and precision of the Ergo Climber gives demolition contractors a fast, efficient solution for challenging concrete removal jobs," said Roger Simonsson, Aquajet Systems managing director. "It uses something already on a jobsite – scaffolding – and turns it into a frame for safe and simple controlled concrete removal." 

The Climber's roller beam and hydraulically synchronized left and right climbers robotically move and position the attached Power Head, directing the water jet to remove concrete from areas 9.8 inches (0.25 metres) to 6.6 feet (2 metres) wide. Aquajet's high-pressure Power Pack provides the required water pressure and flow. 

The Ergo System's controller unit powers and controls the hydraulics. It uses intelligent sensing to allow the operator to program the lance for optimal material removal. The Power Head oscillation is adjustable to 8 or 14 degrees. The lance angle is modifiable up to 45 degrees. The combination results in contractors being able to remove as much as 9 cubic feet of concrete per hour.

The compact Ergo System serves as an effective alternative to hand lances, producing as much as four times the water reaction force —1,000 newtons — to remove concrete while leaving steel reinforcement unscathed.

Aquajet Systems designed the Climber with spring-loaded, high-friction rollers that connect to a lightweight roller beam with just one bolt. Contractors attach the all-wheel drive system to scaffolding pipe with two spring-loaded handles – one for the right and one for the left. The system offers a better grip and aids in the consistency of movement. Safety latches secure the handles in the locked position. The Climber travels well over most types and condition of pipe, including bent pipe, pipe joints, aluminum and steel pipe. Operators can arrange scaffolding to maximize the Climber's effectiveness in a variety of applications.

The compact Ergo System serves as an effective alternative to hand lances, producing as much as four times the water reaction force –1,000 newtons – to remove concrete while leaving steel reinforcement unscathed. 

Beyond the simplicity of the single-bolt connection, the Ergo Climber weighs just 48 pounds and can be carried by one person, making it easier than ever for a contractor to add hydrodemolition services to their offerings. In addition, the Climber system's power head features interchangeable parts with the Ergo Spine and operators can use the Spine roller beam with the Climber, improving convenience for contractors who own both systems.

Keestrack extends worldwide manufacturing

Keestrack prides itself in consistently developing its worldwide manufacturing capacities. The company, which at bauma celebrated its 10,000th production machine since the legendary "4518" was introduced in 1996, is also marking the completion of its new 8740-square-metre assembly complex, the second extension phase of its main factory in Šternberk, Czech Republic. More milestones and new extension projects will be set and started in 2019, including the opening of Keestrack's Indian assembly in Neemrana and new production capacities in Ponzano Veneto, Italy.

Recycled aggregates for roads

Municipalities are responsible for the care and maintenance of vast amounts of roads, from lanes to highways. When those roads are repaired or replaced, there's the potential to generate a significant amount of aggregate material - concrete and asphalt removed from the surface that must be dealt with.
Today's roadbuilding contractors are taking this material and recycling it more than ever before. However, research is showing that some municipalities are far better than others when it comes to using this type of aggregate in their roads - and some are far behind.

LEED changes a boost for C&D

Construction and demolition (C&D) materials are hefty. It is why we can so effectively build roads, bridges and buildings out of them. It's also why, by weight, they are the most significant material in the North American waste stream. This creates a challenge for recycling, as it's usually too expensive, in terms of ROI, to ship most recovered C&D end products, including wood, concrete, drywall, asphalt, and asphalt shingles.

New sidewall protection for OTR tires designed for concrete and aggregates recycling

At concrete and aggregate recycling sites, recycled aggregate is produced by crushing concrete and asphalt to reuse the aggregate in the construction industry as a base for roads or building foundations.  To keep operations running site managers rely on loaders to push large jagged chunks of torn up sidewalk, roadway or building materials - which can contain steel rebar - to the crushing line to reduce its size.

Cat multi-processors feature quick-change jaws, greater cutting/crushing forces, increased speed, durable design

Three new Cat MP332, MP345 and MP365 Multi-Processor models are heavy-duty, high-production tools that accept multiple interchangeable jaws for taking on a variety of specialized demolition tasks. The new models, compared with previous models, can cycle 50 percent faster and generate up to 19 percent greater cutting/crushing forces. An innovative locking system enables a single operator to typically change jaw types in 15 minutes or less, using only standard hand tools. An included stand securely and stably holds unused jaw sets.

  • Concrete Cutter: outer jaw cracks concrete, inner jaw shears steel
  • Demolition: cracks thick concrete structures
  • Pulverizer: crushes concrete, separates rebar
  • Shear: cuts structural steel, pipe, cable
  • Tank Shear: cleanly cuts tanks or plate steel at right angle on three sides
  • Universal: cuts steel and crushes concrete
