Abstract

Method and apparatus for a portable hoisting system having an upright gin pole which is attached to the upright standing very tall pole or tower using a plurality of straps. Extending away from the gin pole is an angularly adjustable arm which is user selectable to be either; e.g., at a 90-degree angle or a 45-degree angle, which arm is supported by a brace connected between the extension arm and the upright gin pole. The gin pole is hollow on its inside which allows a load line to travel through the interior of the gin pole from its lower end to its upper outlet end and includes a plurality of pulleys which allow the load line to travel through the inside of the hoisting system. Also included is a heel block or the like wherein one end of the load line is connected to a capstand hoist disposed on the front or rear end of a vehicle and a ball with hook for supporting a load. Also included optionally is a tag line connected to the load line and being held by a ground member for helping to control the movement of the load.

Claims18

Dependent claims

A system for hoisting a load up a structure using a load line the structure being upright standing and supported on the ground, comprising:

a) a gin pole, wherein said gin pole is elongated having upper and lower ends being attached to the structure so that said gin pole is upright standing and being substantially parallel to a longitudinal axis of the structure, wherein said gin pole is hollow thereby having an interior;
b) an arm having proximal and distal ends, said proximal end being pivotally attached to said upper end of said gin pole, wherein said arm extends laterally away from said gin pole, wherein said arm is hollow thereby having an interior;
c) wherein said arm is angularly adjustable with respect to said gin pole;
d) a brace for supporting said arm, wherein one end of said brace is pivotally connected to said gin pole and an opposite end of said brace is pivotally connected to said arm;
e) a first elbow portion being disposed on said upper end of said gin pole, a second elbow portion being disposed on said distal end of said arm so as to terminate in a free end, said free end of said second elbow portion having a longitudinal centerline which is substantially parallel to a longitudinal centerline of said gin pole;
f) a first and second pulley, wherein one said pulley is mounted on an inside radius of each said first and second elbow portions so that a portion of each said pulley passes through said inside radius and extends into said interior of each said first and second elbow portion;
g) said load line having first and second ends, wherein said load line passes through said interior of said gin pole and said arm, wherein said load line has said first and connected to a capstan on the ground and said second end connected to the load;
and
h) wherein said load line passes over said first and second pulleys so that said load line is disposed in said interior of said gin pole and said arm, wherein said load line is spaced away from an inner surface of said gin pole and said arm.

A method for hoisting a load up a structure using a load line, the structure being upright standing and supported on the ground, comprising the steps of:

a) attaching a gin pole to the structure, wherein the gin pole is elongated having upper and lower ends so that the gin pole is upright standing and substantially parallel to a longitudinal axis of the structure, wherein the gin pole is hollow thereby having an interior;
b) providing an arm having proximal and distal ends, the proximal end being pivotally attached to the upper end of the gin pole, wherein the arm extends laterally away from the gin pole, wherein the arm is hollow thereby having an interior;
c) wherein the arm is angularly adjustable with respect to the gin pole;
d) providing a brace for supporting the arm, wherein one end of the brace is pivotally connected to the gin pole and an opposite end of the brace is pivotally connected to the arm;
e) disposing a first elbow portion on the upper end of the gin pole and disposing a second elbow portion on the distal end of the arm so as to terminate in a free end, the free end of the second elbow portion having a longitudinal centerline which is substantially parallel to a longitudinal centerline of the gin pole when the arm is disposed perpendicular to the gin pole;
f) providing first and second pulleys, wherein one pulley is mounted on an inside radius of each first and second elbow portion so that a portion of each pulley passes through the inside radius and extends into the interior of each first and second elbow portion;
g) wherein the load line has first and second ends, wherein the load line passes through the interior of the gin pole and the arm, wherein the load line has the first end connected to a capstan on the ground and the second end connected to the load;
and
h) wherein the load line passes over the first and second pulleys so that the load line is disposed in the interior of the gin pole and the arm, wherein the load line is spaces away from an inner surface of the gin pole and the arm.
