Mich. Admin. Code R. 408.15753 - Gin poles and rope falls
Rule 5753.
(1)
A gin pole shall be properly attached to the wellhead or Christmas tree with a
chain and ratchet load binder in a manner that prevents movement when the load
is being handled. A chain and ratchet binder used to attach the gin pole to the
wellhead or Christmas tree shall be of a proper size and strength to support
the anticipated load to be handled.
(2) When the gin pole and rope falls are
being used to lift the lubricator or any other heavy object, the load shall be
pulled from as near a vertical position as practicable.
(3) A splice shall not be permitted in the
entire length of rope of a rope fall, except where the dead end is tied
off.
(4) The rope shall be
inspected at the beginning of each job to assure that it has not been partially
cut, frayed, or exposed to chemicals that may weaken it. A rope that has been
weakened by being cut or frayed or that has been in contact with damaging
chemicals shall be immediately replaced.
(5) The blocks of a rope fall shall be
inspected at the beginning of each job for shaft wear, the condition of
bearings, or damaged or severely worn sheaves that may cause rope damage. A
block that shows excess wear or damage shall be immediately replaced.
(6) A wire sling or equivalent that has been
inspected for defects before installation shall be used for the purpose of
securing the lower wire line sheave. The sheave shall be attached to a primary
rig beam, blowout preventer, or permanent stable fixture.
(7) A pin used in the makeup of a sheave
wheel shall be secured with a cotter pin or safety-type pin.
