The Belt Arrestor is a 100% mechanical device. It is operating in cases of loss tension in the belt. There is no hydraulics, pneumatics or electrics which may add additional maintenance problems. It works by using the tension of the belt to keep the device open with mechanical counterweights.
Therefore, during the occurrence of loss tension in the conveyor belt. It may be due to snapping or breaking, the counterweights engages. Thus, activating the Belt Arrestors “jaws.” It is snapping shut almost immediately and prevents the top and bottom belts from running down the incline.
Prolonged downtime in the production process due to a belt breakage is being reduced by up to 90% with the arrestors being fitted. Therefore, minimising the decrease in productivity and lost income.
TOP AND BOTTOM ARRESTORS
There is a top and bottom arrestor, which traps both the top and return conveyor belt and prevents it from running back down the incline. Both ends are then in close proximity to facilitate easy splicing.
The carry side of the conveyor belt is using Top Arrestor. The installation is as close as possible to the head pulley. It exerts a positive clamping force of up to 60 ton.
Only Head Drive conveyor systems uses Bottom Arrestor. The bottom arrestor activates immediately with the Top Arrestor and prevents the belt and counterweight from running away. It exerts a positive clamping force of up to 20 ton.
