Abstract

Abstract A loading apparatus for handling preferably loads supported on pallets. By means of this apparatus it is possible to lift loads positioned at floor or ground level at either side of for instance a truck, up to the loading platform of said truck and to then deposit said loads in any position on the platform, if desired in a stacked pattern. For this purpose the loading apparatus comprises a carriage movable in the longitudinal direction of the truck platform, a mast movable in the vertical direction relatively said carriage and supporting the lifting tool proper, such as a lifting fork, and a projection arm. The projection arm is arranged for movement in its longitudinal direction perpendicularly to the direction of movement of the carriage and horizontally relatively the carriage frame, and it supports the mast which is arranged for vertical displacement thereon. The mast may be arranged to move in a trolley in the vertical direction and the trolley moves in the horizontal direction of the projection arm. This arrangement provides for loading and unloading in an easy and quick manner and on a minimum of space.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 132 words
A loading apparatus comprising a carriage, a projection arm connected to said carriage for sliding movement relative thereto in a horizontal direction perpendicular to the direction of movement of said carriage, a mast mounted on said projection arm and arranged for vertical displacement thereon, a fork supported on said mast, two forwardly directed arms arranged on said carriage, a two armed lever pivotally mounted on the forward end of each of said arms, a runner wheel supported on one lever arm of each of said two armed levers and a preferably hydraulically driven rod system for turning the other lever arm of each of said two armed levers in a vertical plane, this turning movement causing a corresponding degree of tilt of the frame of the carriage, the mast and the fork.
Claim 2
Dependent Claim 132 words
A loading apparatus comprising a carriage, a projection arm connected to said carriage for sliding movement relative thereto in a horizontal direction perpendicular to the direction of movement of said carriage, a mast mounted on said projection arm and arranged for vertical displacement thereon, a fork supported on said mast, two forwardly directed arms arranged on said carriage, a two armed lever pivotally mounted on the forward end of each of said arms, a runner wheel supported on one lever arm of each of said two armed levers and a preferably hydraulically driven rod system for turning the other lever arm of each of said two armed levers in a vertical plane, this turning movement causing a corresponding degree of tilt of the frame of the carriage, the mast and the fork.
Claim 3
Dependent Claim 132 words
A loading apparatus comprising a carriage, a projection arm connected to said carriage for sliding movement relative thereto in a horizontal direction perpendicular to the direction of movement of said carriage, a mast mounted on said projection arm and arranged for vertical displacement thereon, a fork supported on said mast, two forwardly directed arms arranged on said carriage, a two armed lever pivotally mounted on the forward end of each of said arms, a runner wheel supported on one lever arm of each of said two armed levers and a preferably hydraulically driven rod system for turning the other lever arm of each of said two armed levers in a vertical plane, this turning movement causing a corresponding degree of tilt of the frame of the carriage, the mast and the fork.
Claim 4
Dependent Claim 132 words
A loading apparatus comprising a carriage, a projection arm connected to said carriage for sliding movement relative thereto in a horizontal direction perpendicular to the direction of movement of said carriage, a mast mounted on said projection arm and arranged for vertical displacement thereon, a fork supported on said mast, two forwardly directed arms arranged on said carriage, a two armed lever pivotally mounted on the forward end of each of said arms, a runner wheel supported on one lever arm of each of said two armed levers and a preferably hydraulically driven rod system for turning the other lever arm of each of said two armed levers in a vertical plane, this turning movement causing a corresponding degree of tilt of the frame of the carriage, the mast and the fork.
Claim 5
Dependent Claim 26 words
A loading device as in claim 1 further comprising a trolley movable along said projection arm, said mast being arranged for vertical movement on said trolley.
Claim 6
Dependent Claim 107 words
A loading apparatus comprising a carriage, a projection arm mounted on said carriage for sliding movement in a horizontal direction lengthwise of said arm and perpendicular to the direction of movement of said carriage, a trolley mounted on said projection arm for movement therealong, a mast supported for vertical movement on said trolley, a lifting tool supported on said mast, and drive means for effecting the horizontal movement of said projection arm, said drive means comprising a chain supported on said projection arm, guide rollers engaging said chain on opposite sides thereof, and a drive wheel mounted on said carriage and having teeth engaging in said chain.
Claim 7
Dependent Claim 107 words
A loading apparatus comprising a carriage, a projection arm mounted on said carriage for sliding movement in a horizontal direction lengthwise of said arm and perpendicular to the direction of movement of said carriage, a trolley mounted on said projection arm for movement therealong, a mast supported for vertical movement on said trolley, a lifting tool supported on said mast, and drive means for effecting the horizontal movement of said projection arm, said drive means comprising a chain supported on said projection arm, guide rollers engaging said chain on opposite sides thereof, and a drive wheel mounted on said carriage and having teeth engaging in said chain.
Claim 8
Dependent Claim 20 words
A loading apparatus as in claim 3 wherein said trolley is provided with drive means for displacing said mast vertically.
