Abstract
Gripping equipment for lifting apparatuses of the type comprising: a rigid support framework which is adapted to be fixed/attached to the lifting apparatus; and one or more manually controlled gripping members that are firmly fixed to said rigid support framework, and are adapted to grasp and hold a specific object to be moved; said rigid support framework comprising at least one rectilinear tubular element with polygonal cross-section, which is made of metal and has a sectional modular structure.
Claims20
Gripping equipment (1) for lifting apparatuses (100) of the type comprising:
- a rigid support framework (2) which is adapted to be fixed/attached to the lifting apparatus (100);
- and one or more manually controlled gripping members (3) that are firmly fixed to said rigid support framework (2) and are adapted to grasp and hold a specific object to be moved;
- the gripping equipment (1) being characterised in that said rigid support framework (2) comprises at least one rectilinear tubular element with polygonal cross-section (10, 14), which is made of metal and has a sectional modular structure.
A construction method of the gripping equipment (1) of a lifting apparatus (100) wherein the gripping equipment (1) comprises:
- a rigid support framework (2) which is adapted to be fixed/attached to the lifting apparatus (100) and includes at least one rectilinear tubular element with polygonal cross-section (10, 14);
- and one or more manually controlled gripping members (3) that are firmly fixed on said rigid support framework (2), and are adapted to grasp and hold a specific object to be moved;
- said construction method being characterised in that it comprises the steps of:
- manufacturing, for said at least one rectilinear tubular element with polygonal cross-section (10, 14), a pair of rectilinear metallic section-bars (21) having a substantially C- or L-shaped cross-section;
- and then
- fitting the two rectilinear metallic section-bars (21) one into the other, along the respective longer longitudinal edges, so as to form a rigid tubular structure having a polygonal cross-section that substantially copies the shape of said rectilinear tubular element with polygonal cross-section (10, 14).
