The screed’s high-frequency vibration produces uniform vibration distribution over the entire blade length, enhancing the integrity of the concrete. The screed is powered by a 36-V lithium-iron-phosphate battery that boasts over 1,500 lifetime cycles. The E-Screed battery-powered unit can be used with existing Magic Screed blades.

The undercarriage of the 324 hydraulically retracts to a width of just 39 in. for passage through gates and doorways, and it can expand to 54 in.

Digital Level: Take Readings While Waving Digital Level: Take Readings While Waving

The Topcon DL-500 digital-level series has a “wave and read” feature, allowing for readings to be taken while the rod is being waved back and forth, instead of having to keep it plumb. The DL-500 also features random, bi-directional code for the staff software to allow for more accurate readings in less-than-optimal lighting conditions. It also boasts 2,000-point memory and onboard measurement programs for elevation, height difference, ceiling height, cut/fill and stakeout along horizontal distances.
