Abstract
A method of using a wide, flat-bottom, buoyant, amphibious hull with a powered articulating member mounted on the deck. The hull is propelled by at least one engine-driven propeller rotating above the hull. The hull has a shallow draft and distributes its weight over a large area. These features cooperatively provide a vehicle capable of performing overhead work, such as installing or servicing power transmission poles, towers, or other structures located in environmentally sensitive wetlands, swamps, marshes, shallow water, or other terrain.
Claims17
A method for performing overhead work at a power transmission tower comprising the steps of:
- a, launching a vessel comprising:
- i. a hull having a substantially flat bottom;
- ii. at least one drive motor mounted to said hull;
- iii. at least one propeller affixed to each of said at least one drive motor;
- iv. at least one rudder positioned aft of each propeller for steering said hull;
- and
- v. an articulating boom having a first end, a second end and at least one joint between said first and second ends, wherein each such at least one joint is pivotal about a horizontal axis intersecting said joint, and wherein said first end of said articulating boom is pivotally mounted to said hull and is rotatable about vertical and horizontal axes intersecting said first end;
- b. moving said vessel to said power transmission tower, wherein said articulating boom is in a collapsed or partially collapsed position while said vessel is moving;
- c. positioning at least one person near the second end of said articulating boom;
- d. extending said articulating boom;
- and
- e. performing overhead work at said power transmission tower.

A method for performing overhead work at a power transmission tower comprising the steps of:
- a. launching a vessel comprising:
- i. a wide hull having a substantially flat bottom and an upper surface;
- ii. at least one drive motor mounted to said hull;
- iii. a propeller affixed to each of said at least one drive motor;
- iv. at least one rudder positioned aft of each propeller for steering said hull;
- v. an articulating boom, pivotally attached to the upper surface of said hull, comprising:
- aa. a first rigid member having a base and a distal end, wherein said base of said first rigid member rotates about vertical and horizontal axes intersecting said base;
- and
- bb. a second rigid member having a base and a distal end, wherein the base of said second member is pivotally attached to the distal end of said first rigid member, and said second rigid member pivots about a horizontal pivot axis between said first and second rigid members;
- vi. a motor for selectively moving said boom about said vertical and horizontal axes intersecting said base of said first rigid member;
- and
- vii. a motor for selectively extending and retracting said articulating boom;
- b. moving said vessel to said power transmission tower, wherein said articulating boom is in a collapsed or partially collapsed position;
- c. positioning at least one person near the second end of said articulating boom;
- d. extending said articulating boom to an elevated position on said power transmission tower;
- and
- e. performing overhead work at said power transmission tower.
