YHJ-50(A) Laser Slope Gauge


Product Overview

The YHJ-50 laser slope gauge is primarily used for alignment, positioning, and line-setting in mining excavation faces and installation projects. It serves as a modern surveying tool that replaces traditional string lines in applications such as achieving the “three-levels-and-one-straight” standard on coal-mining faces, establishing centerlines for drilling and support in tunneling faces, positioning and installing mechanical and electrical transportation equipment, and setting reference lines in civil engineering and highway construction. The device boasts advantages including compact size, light weight, portability, ease of operation, high operational efficiency, and minimal interference with other work processes.
