Outdoor lighting unit

摘要

Apparatus for illuminating the sloping faces of an open cut mine consists of a trailer which is towable to the site by a four wheel drive vehicle and a mobile cart which travels to and from the trailer. The cart has an array of floodlights and a drive motor which are supplied with power by a cable inside a hose fed from a reel on the trailer. A generator and pump on the trailer supply power for reel rotation and cart travel. The cart has two sets of wheels, one above the other at the front of the cart to prevent tipping as the cart travels down the sloping face. The cart is tethered to the trailer and the reel feed is matched to the cart speed.
