Articulated lifting devices for lifting objects under overhangs

Articulated lifting device comprising:

• a substantially orthogonal support frame having a downwardly extending leg and a forwardly extending upper arm adapted for connection to a hoisting device,
• a load adapter which is able to attach to an object to be lifted having a rearwardly extending arm,
• a connector, pivotably connecting said downwardly extending leg with the adapter arm that allows free rotation of said leg in relation to said arm within certain limits and can lock said leg in predetermined position hereby providing rigid connection,
• whereby said load adapter can be attached to the load to be lifted, and
• whereby said support frame may be pivotably rotated towards said load, and
• whereby said support frame can be rigidly locked in predetermined position thereby creating rigid frame connection with said load adapter, and
• whereby said hoisting device can lift said lifting device together with said load and move to another location.

A method for removal of a part of machinery located under overhanging structure, comprising the steps of:

• providing a load adapter having a rearwardly extending arm and having a counterweight assembly attached to a free end of the adapter arm, and
• providing a substantially orthogonal support frame having a downwardly extending leg and a forwardly extending upper aria suspended off a hoisting device at the free end of said upper arm, and
• pivotably connecting said leg of said frame with said adapter arm and adjusting the counterweight so it balances weight of said load adapter, and
• attaching said load adapter to said part of machinery, and
• rotating said support frame towards said part of machinery until said support frame reaches predetermined position, and
• restricting pivotal movement of said support frame by locking it in predetermined position thereby creating rigid frame connection between said support frame and said load adapter, and
• lilting said part of machinery to take load off supports supporting said part of machinery in place and moving said part of machinery away.

• providing a load adapter having a rearwardly extending arm, and
• attaching said load adapter to said part of machinery, and
• providing a substantially orthogonal support frame having a downwardly extending leg and a connector pivotably attached to the bottom end of said leg and having a forwardly extending upper arm suspended off a hoisting device at the free end of said upper arm, and
• connecting said orthogonal frame to said adapter with said connector, and
• rotating said support frame towards said part of machinery until said support frame reaches predetermined position, and
• restricting pivotal action of said connector thereby locking said support frame in predetermined position thereby creating rigid frame connection between said support frame and said load adapter, and
• lifting said part of machinery to take load off supports supporting said part of machinery in place and moving said part of machinery away.
