Lat Laser Self-leveling Plummet

详情

There shall be a datum for measuring the linearity deviation (the whole range) and the parallelism of two rails. After passing the Liquid Wedge Compensator, laser beam become becomes plumb datum with high precision. Based on this plumb datum, measure the parallel deviation by analyzing the vertically 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. Offing datum on the template for installing vertical elevator. Replace the traditional plummet; improve the verticla 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.
