Power supply winch system
View Patent ↗The power supply winch system comprises a generally inverted L-shaped supportive frame and a winch attached to the supportive frame. The supportive frame comprises a horizontal member and a vertical member that are pivotally attached to one another at one end. The horizontal member has a first horizontal stability bar attached thereto and a flexible strap which depends from a free end of the horizontal member. The vertical member has a winch support affixed to it and a second horizontal stability bar attached to a free end of the vertical member. The winch is secured to the winch support. The inverted L-shaped supportive frame can embrace a corner of the power supply cabinet, such that the horizontal member corresponds with a top surface of the cabinet while the vertical member corresponds with an adjacent side surface. The winch system can be folded into a compact, portable structure.
