Material Processor:Cleans Sand and Gravel

First unveiled at the CONEXPO-CON/AGG trade show, held March 10-13 in Las Vegas, the Combo X900 is a wet-processing system that can handle up to 500 tons per hour. When processing material such as sand and gravel, the Combo X900 can readily remove unwanted clay, silt and organic contaminants. The water tank has been integrated into the overall design rather than being a stand-alone unit, reducing the overall footprint. The system is also more efficient than earlier models, using only 800 gallons per minute of water to wash 500 tons per hour of material.CDE;www.cdeusa.com

Modular Formwork:基础设施的重点

The PERI booth at CONEXPO featured the formwork maker’s new heavy duty column system as well as its modular dance floor system for bridge piers. The column system allows for corner ties to be spaced 2 ft apart, with no impact wrench needed for removal. The modular dance floor system is designed for rebar and post-tensioning tasks as well as concrete placement and any other tasks that need to be performed on bridge pier caps. The length of modular beams can be adjusted, allowing for reuse.佩里；www.peri-usa.com

Track Drill Rig:Remote Control

LSGT+HDA在ConexPo 2020展览会上推出，是一款专门针对土壤采样和岩土技术应用的遥控轨道钻。轨道机的地面压力仅为3.8 psi，非常适合在环境敏感的区域工作。可以调整机器的每个角落的高度，以确保在不平坦的地面钻孔过程中保持水平。该钻头带有140磅自动锤，并能够将样品收集到100英尺。Lone Star Drills;www.lonestardrills.com

Pipe Extractor:无风煤管更换

Seen first at CONEXPO, the SLX1300 trenchless pipe extraction system can be used to replace coated and bare-steel gas service lines from 1⁄2 in. to 11⁄4 in. in diameter at lengths up to 100 ft. The system is hydraulically driven and offers up to 13.3 tons of pulling force. By pulling new HDPE or MDPE pipe into the same path as the old pipe, the SLX1300 saves time and avoids disrupting ground conditions. It features on-board shears to cut up the extracted pipe as it is removed. The entire unit can function within a 4-ft by 4-ft working pit and is small and light enough to be transported in the back of a pickup truck.无锤trench;www.hammerheadtrench.com
