Abstract
An articulated vehicle with pivoting motion, on which the forward carriage supports a loading shovel for a forklift and the rear carriage a counterweight, at least a portion of the counterweight being displaceably arranged on a rear guide mounted transversely to the rear carriage and being so connected with the forward carriage that for every pivoting excursion an opposite displacement of the counterweight is achieved.
Claims14
A pivoting vehicle, comprising:
- (a) a forward carriage and a rear carriage including a rear end portion;
- (b) hinge means defining a pivot axis connecting said forward and rear carriages to permit pivoting excursions of at least one of said carriages about said axis;
- (c) pivot control means associated with said forward and rear carriages for pivoting excursions of at least one of said carriages;
- (d) work means mounted to said forward carriage;
- (e) guide means mounted to said rear end portion and extending transversely thereof;
- (f) counterweight means mounted to said guide means and adapted for lateral displacement along said guide means;
- and,
- (g) control means associated with said counterweight means and said forward carriage for cooperative lateral displacement of said counterweight means by pivoting of at least one of said forward and rear carriages whereby proportional displacement of said counterweight means is associated with each pivoting excursion of at least one of said forward and rear carriages and in a direction opposite thereto.
