Abstract
A receptacle transporting vehicle adapted to carry an open-top receptacle, such as a slag pot, includes an upper or scull frame adapted to retain and support the receptacle thereon and a dumping frame positioned between the scull frame and a mobile main frame. The scull frame and the dumping frame are each pivotally mounted on the main frame and respective extensible members effect movement of the scull frame and the dumping frame and thereby movement of the receptacle to a position for discharging the contents thereof. The scull frame has hook portions and movable keeper members engageable with respective trunnion portions of the receptacle for retaining the receptacle in supported engagement during transportation and the discharging of the contents thereof.
Claims10
A receptacle transporting vehicle comprising:
- (a) an elongated mobile main frame having a forward end portion and a pair of side members extending rearwardly from said forward end portion and spaced transversely outwardly from a longitudinal central axis of said main frame, said side members of said main frame each having a rear end portion;
- (b) an elongated dumping frame having a forward end portion and a pair of side members extending rearwardly from said forward end portion and spaced transversely outwardly from a longitudinal central axis of said dumping frame, said side members of said dumping frame each having a rear end portion thereof pivotally mounted on the rear end portion of respective side members of said main frame;
- (c) an elongated scull frame having a forward end portion and a pair of side members extending rearwardly from said forward end portion and spaced transversely outwardly from a longitudinal central axis of said scull frame, said side members of said scull frame each having a rear end portion thereof pivotally mounted on the rear end portion of respective side members of said main frame;
- (d) extensible means extending between said forward end portion of said main frame and each of said side members of said dumping frame for urging said dumping frame about said pivotal mounting thereof for raising and lowering said dumping frame relative to said main frame;
- (e) extensible means mounted on said side members of said dumping frame and each having one end portion thereof pivotally connected to a respective one of said side members of said scull frame for effecting pivoted movement about the pivotal mounting of said scull frame between a first position for carrying a receptacle and a second position for discharging contents of the receptacle rearwardly of the vehicle, said pivotal movements of the scull frame and the dumping frame each supplementing the other in tilting the receptacle;
- and
- (f) means on said scull frame for engaging trunnion portions of the receptacle and for retaining the receptacle in supported engagement during discharging contents of the receptacle;
- (g) said extensible means between the dumping frame and scull frame being double acting hydraulic cylinders and operable to swing the scull frame through an arc in the nature of 45.degree. relative to the dumping frame;
- (h) said extensible means between the forward end portion of said main frame and each of the side members of said dumping frame being two stage hydraulic cylinders with one stage being double acting and one stage being single acting, said two stages hydraulic cylinders being operable to swing the dumping frame through an arc in the nature of 75.degree. relative to the main frame and the combined movement of the dumping frame and scull frame moves the scull frame through an arc in the nature of one hundred twenty degrees relative to the main frame;
- and
- (i) said two stage hydraulic cylinders having the double acting stage operable to retract the dumping frame to a position for the weight of the dumping frame, scull frame and empty receptacle further returns the dumping frame to the first position thereof.
