Hamburg Wheel Tracker - Tracking Device QualiHWT™ 340
Hamburg Wheel Tracker - Tracking Device QualiHWT™ 340 is a laboratory testing device designed for the asphalt industry. It evaluates the durability and resistance of asphalt mixes to water damage and wear.
Built with corrosion-resistant, high-grade 304 and 316 stainless steel tubing, the QualiHWT™ 340 model features a rigid frame and reinforced wheel assemblies. This ensures precise rut depth measurements without interference from machine flex. The electronics are securely housed in a custom stainless steel cabinet, protecting them from environmental exposure while allowing for easy maintenance and plug-and-play component replacement.
The Auto-Lift Feature automates the testing process by preventing pre-loading effects during sample conditioning. It also ensures both samples undergo full testing, even if one does not complete the test
