ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to the movement of loads and more particularly, to devices and systems for accomplishing the movement of loads.
2. Background Information
A winch provides a stationary hoisting machine from which a load may be raised or lowered by wrapping a cord or rope around a drum. Such devices are commonly used in rescue operations. However, such devices generally require a great deal of area to set up and maneuver the winch assembly and considerable time to set the system up for proper operation. There is needed a device for raising or lowering a load that may be used in a confined area and may be assembled and put in place in short order.
SUMMARY OF THE INVENTION
The invention relates to a recovery device particularly useful in confined space and remote rescues. The recovery device includes a base plate, a winch coupled to the base plate, and an anchoring plate coupled to the base plate to detachably couple the base plate to an object that will support the recovery device. A cord is attached to the winch to raise or lower the load to or from the recovery device. A guide roller assembly is coupled to the base plate to guide the cord and allow the cord to be wound properly on the drum when raising a load with the winch.
The recovery device is particularly useful with a confined space derek load management system such as, for example, a tripod (three leg) or quadpod (4 leg) system. The recovery device may be quickly and easily secured or coupled directly to a leg of the tripod to reduce the amount of area or space needed to complete the recovery. The recovery device may also be coupled to a vehicle trailer hitch receiver. In this manner, in remote areas or inadequate work space environments, the recovery device can be coupled to a vehicle to support the recovery.
The recovery device may also be coupled to a support object resembling a letter “H.” In this manner, the device can be quickly transported to remote off-road or into back-country environments for recovery support.
