What it is
Machine control system Trimble Earthworks 3D for dozer Spektra. Key specifications: type 3D levelling control system for dozers, operating system Android, display Trimble TD520 10" touchscreen.
Laser and surveying instruments include laser distance meters, laser levels, rotary lasers, GNSS receivers and machine control systems, with tripods and accessories, for measuring and setting out.
What it is for
Used for levelling surfaces and structures and for setting out and in earthmoving work.
How to use it
Set the instrument on a tripod or stable base, away from vibration, and let it self-level or level it manually. Before starting, check accuracy against a known reference and, outdoors, use the detector or staff to read the beam. Never look into the laser beam, and transport the instrument switched off in its case.
