Abstract
An overhead sawing device comprising a central frame, a cutting cable, a driving unit, a first and a second arms configured to deflect the cutting cable to a lower level, at least two rotatable arms configured to receive the cutting cable from the higher level and to guide said cable during a cut. The device further includes a telescopic cable tensioning element. A method of operating the device is also provided, which method permits the execution of a continuous cut without repositioning the device, even in confined spaces.
Claims13
An overhead sawing device comprising:
- a. a central frame further comprising a horizontal bottom level and a horizontal top level connected to the horizontal bottom level by a plurality of substantially vertical elements;
- b. a cutting cable stored in a cable storage, said cable storage being mounted on the top level of the central frame, said cable storage having a first row of axially aligned pulleys and a second row of axially aligned pulleys placed opposite to the first row of axially aligned pulleys;
- c. a driving unit rigidly attached to the top level of the central frame, said driving unit comprising a horizontal pulley drivable by a motor, said driving unit being configured to receive and move the cutting cable towards other elements of the overhead sawing device;
- d. a first arm having a first horizontal section radially extending from the top level of the central frame, said first arm further having a second vertical section extending downwards from a distal end of the first section, the first arm is further having a first deflecting pulley at the distal end of said first section and a second pulley at a distal end of the second section;
- e. a second arm having a first horizontal section radially extending from the top level of the central frame and in a direction opposite to that of the first arm, said second arm further having a second vertical section extending downwards from a distal end of said first section, the second arm is further having a first deflecting pulley at the distal end of said first section and a second pulley at a distal end of the second section;
- f. at least two rotatable arms, each rotatable arm having a first radially extending section radially extending from a base rotatably attached to the central frame, each of which the bases being located between the top level and the bottom levels of said central frame;
- and
- g. a telescopic cable tensioning element mounted on the top level of the central frame and adjacent to the cable storage;
- wherein each of the at least two rotatable arms further has a second vertical section extending downwards from the first radially extending section, and wherein a distal end of each said second vertical section of the at least two rotatable arms has at least two horizontal pulleys.
