Belt tensioning device  
to control the belt tension along the length
of the conveyor		  
 
Construction and function:  
Placed at the sides of the belt frame, the VHV tensioning device saves space by reducing the take-up area needed behind the drum. The stretching device tightens and loosens the conveying belt by pushing the complete drive or return station, including the head pulley and scraping plow. This way, adjustment of the head pulley is not necessary anymore, while tensioning the belt later. No impurities can gain access to the drum due to constant gap between the drum and the scraping plow. The take-up section is operated by a spindle, which is working against a fix point. The spindles in the sliding block that is used as a fix point are mounted to the sides of the belt frame, which helps avoid a "jam" due to their orientation. The spindles are protected from impurity due to the design of the tension system. They are protected by the conducts at the sides of the conveyor and at the top by a pressure pad.
