The heavy NESTLE elevating tripod with centre column is ideal for positioning heavy line and rotary lasers. On tripods with self-locking, the telescope is moved very easily and precisely to a desired height by means of a crank drive (crank stroke per revolution 1.2cm). The main application of this tripod is is benchmarking work or tasks with working heights (90-188cm). The integrated circular level ensures quick and easy set-up. With a 35cm crank stroke, instruments can be set up steplessly and precisely to a desired height. The other technical features, such as stable tread shoes, spreader stop, eccentric clamping, anodised aluminum, plastic parts made of fibreglass-reinforced polyamide, and high quality workmanship ensure many years of use under the toughest conditions.
