Building limit measuring device LDM300A for scaffolding measurements in station redevelopment construction.
Using a "building limit measuring device" for distance measurements of structures such as scaffolding and temporary installations during redevelopment work at major stations can significantly reduce work time.
This is a "building clearance measuring device" that can measure the distance for railway operators and railway-related construction workers. Its main purpose is to be used for measuring the clearance from railway facilities such as tunnels, platforms, signals, and scaffolding or temporary structures associated with station redevelopment work. The rotation angle of the internal laser distance sensor is controlled by an internal motor, allowing for continuous or single measurements to be performed automatically or manually. The measurement results are saved to a microSD card, enabling serial data communication output to a PC or other devices. A dedicated base is used to install the measuring device on the track, and it can simultaneously measure cant and slack along with the building clearance measurement values. To measure, the base is installed on the rail, and the laser is directed at the desired measurement point while pressing the measurement switch. The horizontal distance from the rail surface and track center, as well as the height, are measured, and the measurement point is simultaneously plotted on the building clearance diagram, with the clearance value calculated. 【Features】 ■ Equipped with a color graphic LCD - Allows for confirmation of measurement results on-site ■ Inclination sensor included - Cant measurement is possible with the dedicated base ■ Compact & labor-saving - Has a widening measurement function *If you are interested in renting, please indicate your rental request by clicking the "Contact Us" button below.
