Claim 1
Independent Claim
162 words
A device (1) for displacing a stack of objects such as boxes or bales comprising a carrying frame (2), a supporting structure (3) for the stack connected with said frame (2) and defining a supporting surface, a lifting device (4) engaging the carrying frame by a lifting member, for example a hoisting cable (5), at a distance above the supporting structure (3) and a push-off device (6) connected with the carrying frame (2) and comprising a pushing member (7) movably guided by guide means (10, 11) along the supporting structure (3) and driven by driving means (86) and coming into contact with a side face of the stack characterized in that the lifting member (5) engages an engaging member (75) movable between a high and a low position and connected with the carrying frame (2) and coupled with energy storing means (74, 82) receiving energy for the driving means (86) at least during a movement from the low to the high position.
Claim 2
Independent Claim
162 words
A device (1) for displacing a stack of objects such as boxes or bales comprising a carrying frame (2), a supporting structure (3) for the stack connected with said frame (2) and defining a supporting surface, a lifting device (4) engaging the carrying frame by a lifting member, for example a hoisting cable (5), at a distance above the supporting structure (3) and a push-off device (6) connected with the carrying frame (2) and comprising a pushing member (7) movably guided by guide means (10, 11) along the supporting structure (3) and driven by driving means (86) and coming into contact with a side face of the stack characterized in that the lifting member (5) engages an engaging member (75) movable between a high and a low position and connected with the carrying frame (2) and coupled with energy storing means (74, 82) receiving energy for the driving means (86) at least during a movement from the low to the high position.
Claim 3
Dependent Claim
28 words
A device as claimed in claim 1 characterized in that the energy storing means comprise a hydraulic jack (74) and a hydraulic accumulator (82) coupled with the former.
Claim 4
Dependent Claim
173 words
A device as claimed in claim 2 characterized in that the engaging member comprises a lever (75) journalled on the carrying frame (2), a first lever arm being engaged by the lifting member (5) and a second lever arm being engaged by the jack (74), the jack being connected with the lever (75) and the carrying frame (2) in a manner such that in the low position (Fig. 7) the engaging point (77) of the lifting member (5) is located considerably below the bearing (76) and the point (78) of engagement of the jack (74) is located substantially at the same distance from its end (80) connected with the carrying frame as the bearing (76), whereas in the high position (Fig. 8) the point (77) of engagement of the lifting member (5) is located substantially at the same height as the bearing (76) whereas the point (79) of engagement of the jack (74) is located at a considerably different distance from its end (80) connected with the carrying frame than the bearing (76).
Claim 5
Independent Claim
49 words
A device as claimed in anyone of the preceding claims characterized in that at the end remote from the supporting structure (3) the carrying frame (2) is provided with supporting wheels (87) rotatable about a shaft (13) extending transversely of the direction of movement of the pushing member (7).
Claim 6
Independent Claim
56 words
A device as claimed in anyone of the preceding claims characterized by a supporting frame (106) adapted to be separately positioned on a loading site (109) and provided with supporting means (114) supporting the carrying frame (102) in a direction opposite the pushing-off direction and engaging means (112) transferring forces and engaging the loading site (109).
Claim 7
Dependent Claim
33 words
.6. A device as claimed in claim 5 characterized in that the supporting frame (106) comprises carrying frame guides (114, 115, 116) co-operating with the carrying frame (102) and converging in downward direction.
Claim 8
Dependent Claim
31 words
A device as claimed in claim 5 or 6 characterized in that the supporting frame (106) comprises at its foremost end, viewed in the pushing-off direction, rearwardly converging pallet guides (118).
Claim 9
Independent Claim
41 words
A device as claimed in anyone of claims 5 to 7 characterized in that at the foremost end, viewed in the pushing-off direction, the supporting frame (106) is provided with at least one roller (119) rotatable about a horizontal, transverse shaft.
Claim 10
Independent Claim
50 words
A device as claimed in anyone of claims 5 to 8 characterized in that a ballast (117) is arranged on the supporting frame (106) and the engaging means comprise horizontal, flat elements (112) of material such as rubber having a high friction coefficient with respect to the loading site (109).
