Rokade roto technicks offers belt transmission alignment [bta] from progressive technologies. This is a perfect tool for alignment of belt transmissions and chain drives. It is easy to use and much quicker than old techniques. An easily visible laser line projected on to the targets allows on to quickly ascertain and correct the misalignment of sheave and pulley. When the line lies in the target slots, the machine is in the right position. The result is a fast and accurate alignment. Immediately after switching on the bta, a laser line is projected on to the targets, which show the vertical and horizontal misalignment at the same time. One can watch the moves live during the alignment procedure that can be done by a single operator, which saves precious man-hours, making this the most cost-effective maintenance tool. The process saves money and energy [power] by reducing belt/sheave wear and vibrations; and increases available machine time by reducing costly machine downtime due to sheave and pulley misalignments.
