International Classification:

B66C 2342

US Classification:

212300

Abstract:

In connection with a pair of pivotally connected articulating booms there is a pair of double-acting hydraulic cylinders which control the vertical pulling of well pipe, such that a boom assembly in conjuction with an improved winch assembly willgenerate at least a 1500 pound perpendicular pulling force to a vertical height of at least 23. 5 feet. This is done with a mini hoist, releasably mounted upon a hydraulically self-propelled 4. times. 4 vehicle. The entire weight of the mini hoist is less than 1500 pounds and in the collapsed stage can fit within a box truck or on a pickup truck.

Abstract:

A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element comprises a rigid plastic body of appreciable length to produce the standoff effect and a metal retaining member integrally mounted on the plastic body at an operative end thereof. The metal retaining member has main and retaining portions, the main portion being fixedly disposed within the plastic body and the retaining portion extending outwardly from the plastic body having a resilient reverse bend segment, and being adapted for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of the body length to physically secure the circuit board or other element to the plastic body adjacent to the operative end.
