Abstract
Techniques facilitating increased operational reliability for jib cranes are provided. In one example, a jib crane can comprise a mast, a shaft mechanism, and a rod. The mast can extend vertically from a base structure. The shaft mechanism can be disposed within the mast. The rod can be coupled to a boom arm and can be disposed within the shaft mechanism. Rotation of the rod can facilitate continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.
Claims25
A jib crane, comprising:
- a mast extending vertically from a base structure;
- a shaft mechanism disposed within the mast;
- and
- a rod that is coupled to a boom arm and is disposed within the shaft mechanism, wherein rotation of the rod facilitates continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.
An apparatus, comprising:
- a boom arm coupled to a rod disposed within a shaft mechanism that is disposed within a mast extending vertically from a base structure, wherein rotation of the rod facilitates continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.
An apparatus, comprising:
- a shaft mechanism disposed within a mast extending vertically from a base structure, wherein the shaft mechanism supports a boom arm;
- and
- a rod disposed within the shaft mechanism, wherein rotation of the rod facilitates continuous rotation of the boom arm about a longitudinal axis of the rod with respect to the base structure.
An apparatus, comprising:
- a rod disposed within a mast extending from a base structure;
- a boom arm coupled to the rod via a proximal end of the boom arm, wherein the boom arm is continuously rotatable about a longitudinal axis of the rod with respect to the base structure;
- and
- a mounting bracket that facilitates coupling a load to a distal end of the boom arm that opposes the proximal end of the boom arm coupled to the rod.
A computer-implemented method comprising:
- coupling, by a system operatively coupled to a processor, a load to a distal end of a boom arm comprising a proximal end coupled to a rod disposed within a shaft mechanism disposed within a mast extending vertically from a base structure, wherein the boom arm is continuously rotatable about a longitudinal axis of the rod with respect to the base structure;
- and
- transferring, by the system, the load from a first position to a second position by rotating the boom arm about the longitudinal axis.
