All of these systems also employ constant-tension winches for take-up control. These systems have been around for about 20 years, but they have not been used on slope conveyors until recently. Most slope belts use gravity take-ups, which require a lot of maintenance. These new conveyor systems integrate constant-tension winches with VFDs.

The feature that increases the reliaBELT's capacity beyond that of industry standard belt conveyors is the belt width. A 20" inch belt in a 10" tube means the belt wraps around ¾ of the tube, thus carrying the product and minimizing damage. reliaBELT can move 4 tonne per minute which surpasses any of 10" belts on the market meaning ...

The take-up winches are installed on the conveyor gravity take-up tower. The winch is attached to the termination point of the take-up roller tensioning system. The winch positions the take-up weight in the tower such that it can travel freely and is also used to adjust the position of the take-up weight as the belt adopts its permanent stretch.

Tension in a conveyor belt is fundamental to its very operation in terms of supporting the load between rollers and enabling the drive to impart motion to it. For a conveyor on the verge of slipping, there is a direct ratio between T1, the traction force imparted to the Conveyor and T2, the Take-Up Tension, of a Conveyor Belt. This ratio is of the

The conveyor take-up winch will act on the associated take-up pulley trolley via a sheaved cable system with a 4:1 reeving ratio. A load cell connects the wire socket to the lug on the take up winch base frame. The load cell is wired to a load cell monitor, which provides an output signal of the belt tensions for display on the LCS and ...
