Tower hoist, platform and davit system

A method of securing a hoist system to a tower pole comprising a tower pole top located above the ground, a tower pole bottom and a tower pole height extending from the tower pole top to the tower pole bottom, the method comprising assembling a hoist system by performing the following steps in any suitable order including simultaneously:

• a) securing a first clamp bracket system to the tower pole by placing the first clamp bracket system at least partially around the tower pole;
• and
• b) providing a hoist system comprising a hoist beam comprising a forward end, a rear end, a hoist beam length extending from the forward end to the rear end;
• wherein, at least after complete installation,
• i) the first clamp bracket system connects the hoist beam rear end to the tower pole;
• ii) the hoist beam extends laterally from the tower pole and the first clamp bracket system;
• iii) the hoist beam further comprises at least one load-end sheave and at least one return sheave located rearwardly relative to the at least one load-end sheave;
• iv) a brace cable connects the hoist beam to the tower pole and extends at an angle relative to the tower pole height and comprises an upper end connected to the tower pole and a lower end connected to the hoist beam;
• and
• v) the first clamp bracket system comprises a first clamp central bracket comprising a front side connected to the rear side of the hoist beam, a rear side facing the tower pole and opposite the front side, a left side and a right side and a cable system extending partially around the tower pole and comprising a first end connected to the left side and a second end connected to the right side, wherein a horizontally-oriented pivot bolt pivotably connects the hoist beam to the first clamp central bracket, the horizontally-oriented pivot bolt configured to allow the hoist beam to rotate clockwise and/or counter-clockwise about a horizontally-oriented pivot bolt pivot axis extending generally perpendicular to the tower pole height, wherein rotation of the hoist beam about the horizontally-oriented pivot bolt pivot axis allows the hoist beam forward end to move upward and downward and toward and away from the tower pole top, a lower vertically-oriented pivot bolt pivotably connects the hoist beam to the first clamp central bracket, the lower vertically-oriented pivot bolt located rearwardly relative to the horizontally-oriented pivot bolt, the lower vertically-oriented pivot bolt configured to allow the hoist beam to rotate clockwise and/or counter-clockwise about a lower vertically-oriented pivot bolt pivot axis extending generally parallel to the tower pole height, wherein rotation of the hoist beam about the lower vertically-oriented pivot bolt pivot axis allows the hoist beam to rotate at least partially around said tower pole in the plane perpendicular to the tower pole height, and wherein the first clamp bracket system further comprises a brake, the brake, when engaged, configured to prevent rotation of the hoist beam clockwise and/or counter-clockwise about the lower vertically-oriented pivot bolt pivot axis.
