Abstract

GRUA PLEGABLE. ESTA FORMADA POR UNA BASE FIJA (1) APOYADA EN EL SUELO Y UN SOPORTE GIRATORIO (3) QUE COMPRENDE LOS MECANISMOS DE ACCIONAMIENTO DEL MASTIL, PLUMA Y CONTRAPESOS. EL MASTIL ESTA FORMADO POR UNA VIGA ARRIOSTRADA EN SU BASE POR LAS DIAGONALES (8) - (16) UNIDAS MEDIANTE VIELAS ABATIBLES (13) DOTADAS DE VARIAS POSICIONES DE MONTAJE. EN SU PARTE SUPERIOR SE ENCUENTRA EL TRIANGULO (21) ARTICULADO AL PIE DE LA PLUMA (23) CONSTITUYENDO UN PARALELOGRAMO DEFORMABLE. LA PLUMA ESTA FORMADA POR UNA PUNTA (34), UN TRIANGULO ABATIBLE CENTRAL (35) UNIDO MEDIANTE LAS BIELAS (36) Y (37) Y UN PIE (23). EL ACCIONAMIENTO DE LA GRUA SE REALIZA POR EL CABRESTANTE (40). EN EL PLEGADO LA PLUMA SE ALOJA EN EL HUECO EXISTENTE ENTRE EL MASTIL Y SU PIE (4) Y SOBRE LA BASE (1) SE FIJAN UNAS RUEDAS FACILITANDO SU TRANSPORTE.
