RL-H4C dB (PN 57177) RL-H4C DB level laser system with LS - 80 l receiver, clip 6 bar mount, suitcase, all batteries, DB - 74 battery door (no charger jack using the DB version), user manual and 5 year warranty card.
Vertical measurement is an important part of engineering measurement, especially the construction of a large number of modern urban high-rise buildings, the building height increases, and the construction site is often narrow and the vertical quasi measuring method and the instrument is more necessary to exchange and discussion. Verticality measurement of traditional methods by hanging ball hammer, theodolite and laser collimator to vertical projection by layer transfer coordinate, but these methods often subject to restriction or interference of environment and construction conditions, for example, the wind speed is too large, the view is obstructed, in light of laser spot is not clear. TOPCON RLVHDB rotation of the laser instrument for construction of vertical and horizontal measurement lofting, a wide range of uses, one person can operate. Instruments can be arranged vertically or horizontally arranged, after starting the automatic leveling, in vertical and horizontal directions to emit laser beam, and the laser beam rotary scanning out of a high precision horizontal or vertical plane (Figure 1). In addition, the apparatus is also provided with a receiver of a L30 inscribed markings (Figure 2). When rotating laser beam scanning to the location of the index line (accuracy of 0.1snun, receiving distance is up to 800 m), the receiver sends out the sound of chirping, namely by auditory graphs Zi 2O 3 receiver to replace visual judgment, in bright sunlight, can still use. Using this feature, the instrument can also be used for high-rise building vertical measurement. Sichuan Province construction machinery engineering company has high-rise buildings in the building materials market in Chengdu, Jinmao building, Shenzhen building practice, have reached a good effect, were rated as excellent engineering, now the specific operation method is briefly described as follows: when the construction site is narrow hours, using the traditional control method, according to the high
