Abstract
A method and system for removing mortar from a plurality of joints between a plurality of masonry units in a masonry structure, incorporating a suspension work platform, a work tool, and an articulating arm system (500).
Claims20
A method for removing mortar from a plurality of joints (J) between a plurality of conjoined masonry units (MU) in a vertical stationary masonry structure (MS), comprising:
- a) elevating a suspension work platform (1300) to a working height of at least six feet;
- b) supporting a work tool (200), having a work tool weight, from an articulating arm system (500) attached to the work tool (200) and the suspension work platform (1300);
- c) adjusting the work tool (200) position to a desired initial work tool elevation;
- d) adjusting the work tool (200) position to a desired cutting depth between the plurality of conjoined masonry units (MU);
- e) advancing the work tool (200) in a longitudinal X-direction along a portion of at least one of the plurality of joints (J) and removing mortar;
- f) removing the work tool (200) from between the conjoined masonry units (MU);
- g) elevating the work tool (200) to a second working height;
- h) adjusting the work tool (200) position to a second cutting depth between the plurality of conjoined masonry units (MU);
- i) advancing the work tool (200) longitudinally along a portion of at least one of the plurality of joints (J) and removing mortar;
- and
- j) removing the work tool (200) from between the conjoined masonry units (MU).

A method for removing mortar from a plurality of joints (J) between a plurality of conjoined masonry units (MU) in a vertical stationary masonry structure (MS), comprising:
- a) elevating a suspension work platform (1300) to a working height of at least six feet using at least one suspension work platform hoist system lift (1430);
- b) supporting a work tool (200), having a work tool weight, from an articulating arm system (500) attached to the work tool (200) and the suspension work platform (1300);
- c) adjusting the work tool (200) position to a desired initial work tool elevation by the application of an external elevation adjustment force that is less than twenty percent of the work tool weight;
- d) adjusting the work tool (200) position to a desired cutting depth between the plurality of conjoined masonry units (MU);
- e) advancing the work tool (200) in a longitudinal X-direction along a portion of at least one of the plurality of joints (J) and removing mortar;
- f) removing the work tool (200) from between the conjoined masonry units (MU);
- g) elevating the work tool (200) to a second working height by the application of an external elevation adjustment force that is less than twenty percent of the work tool weight;
- h) adjusting the work tool (200) position to a second cutting depth between the plurality of conjoined masonry units (MU);
- i) advancing the work tool (200) longitudinally along a portion of at least one of the plurality of joints (J) and removing mortar;
- and
- j) removing the work tool (200) from between the conjoined masonry units (MU).
