RUNNING GEAR FRAME OF SELF-PROPELLED LOAD-LIFTING CRANE

FIELD: building machinery; load-bearing frames of self-propelled load-lifting machines. SUBSTANCE: frame cross and longitudinal beams. Longitudinal beam is made in form of box-section beam with base unit for slewing circle. Novelty is that base unit is made in form of prism of height equal to height...

Beschreibung
Zusammenfassung:	FIELD: building machinery; load-bearing frames of self-propelled load-lifting machines. SUBSTANCE: frame cross and longitudinal beams. Longitudinal beam is made in form of box-section beam with base unit for slewing circle. Novelty is that base unit is made in form of prism of height equal to height of box section of frame longitudinal beam. Upper and lower webs of longitudinal beam of frame serve as upper and lower bases for base unit. EFFECT: increased rigidly over perimeter of slewing circle, its longevity and reliability at minimum weight of frame, improved manufacturability. 3 dwg
