Abstract
A looped cable control device for use in guiding a supply cable to a mineral winning machine in a longwall mining installation to reduce the risk of damage, the device being mountable on a spill plate to form an elongate of side wall parallel to the spill plate, a platform being mounted between the spill plate and the goaf side wall, so that a trough is defined for receiving the supply cable, the goaf side wall being pivotally mounted for deflection towards the spill plate under impact, the goaf side wall having a projecting lever arm, which engages between a stop and a resilient member, so that the resilient member resists deflection and returns the wall to its normal position, risk of damage by the impact being, therefore, reduced.
