On a more than 150 m high building in Dubai we delivered and installed a tower clock with a dial diameter of 14 m. The figures are more than 2 m long. The four-sided clock has for motor hand drives MHD14000 with single drive, which are special designed and statically calculated as well as the hands due to high wind load requirements. The master clock PERCONTA with GPS receiver controls the complete clock system. The special developed remote system allows to operate the clock also from our workshop here in Germany. Each of the dials can be controlled separately. The clock is visible and readable over kilometres. This is the biggest clock in the United Arab Emirates.
