Lat Laser Self-leveling Plummet (NEW)

Description

There shall be a datum for measuring the linerrity deviation ( the whole range ) and the parallelism of two rails. After passing the Liquid Wedge Compensator, laser beam becomes plumb datum with high precision. Based on this plumb datum, measure the verticality and lineraity deviation of the guide rails as well as the parallel deviation by analyzing the verticality of the two guide rails. This is the key technology in the product. Due to settlement of building and the contraction of the cement wall, the in-use elevator could not be inspected conventionally. Now we make it possible to measure the linearity deviation of in-use elevator. Offering datum on the template for installing vertical elevator. Replace the traditional plummet; improve the vertical precision and working efficiency. Quality testing after the guide rail installation, ensure a smooth comfortable running car. Inspect the guide rail to find the deviation and amendment value while there is swag of in-use elevator. Inspection and amendment of original guide rail for rebuilding elevator.
